Accounting Policies [Abstract]
Fiscal Year	Fiscal Year Typically, the Company's fiscal quarters and fiscal year consist of 13 and 52 weeks, respectively, ending on the Saturday closest to the end of the corresponding calendar quarter for the Company's fiscal quarters and on the Saturday closest to December 31 for the Company's fourth fiscal quarter and fiscal year. As a result of the difference between the fiscal and calendar periods, a 53rd week is added to the Company's fiscal year every five or six years. In a 53-week fiscal year, the Company's fourth fiscal quarter contains 14 weeks. The Company's fiscal year ending January 3, 2015 (fiscal 2014) contained 53 weeks and the Company's fiscal year ending January 2, 2016 (fiscal 2015) contains 52 weeks. Each quarter of fiscal 2014 and 2015 contains 13 weeks, except the fourth quarter of 2014, which contained 14 weeks.
Critical Accounting Policies	Critical Accounting Policies Critical accounting policies are defined as those that entail significant judgments and estimates, and could potentially result in materially different results under different assumptions and conditions. The Company believes that the most critical accounting policies upon which its financial position depends, and which involve the most complex or subjective decisions or assessments, concern revenue recognition and accounts receivable, warranty obligations, income taxes, the valuation of goodwill and intangible assets, inventories and pension obligations. A discussion of the application of these and other accounting policies is included in Notes 1 and 3 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the fiscal year ended January 3, 2015.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Although the Company makes every effort to ensure the accuracy of the estimates and assumptions used in the preparation of its condensed consolidated financial statements and in the application of accounting policies, if business conditions were different, or if the Company were to use different estimates and assumptions, it is possible that materially different amounts could be reported in the Company's condensed consolidated financial statements.
Warranty Obligations	Warranty Obligations The Company provides for the estimated cost of product warranties at the time of sale based on the actual historical occurrence rates and repair costs, as well as knowledge of any specific warranty problems that indicate that projected warranty costs may vary from historical patterns. The Company typically negotiates the terms regarding warranty coverage and length of warranty depending on the products and applications. While the Company engages in extensive product quality programs and processes, the Company's warranty obligation is affected by product failure rates, repair costs, service delivery costs incurred in correcting a product failure, and supplier warranties on parts delivered to the Company. Should actual product failure rates, repair costs, service delivery costs, or supplier warranties on parts differ from the Company's estimates, revisions to the estimated warranty liability would be required.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-08, which provides new guidance on reporting discontinued operations and disclosures of disposals. Under the new guidance, only disposals representing a strategic shift in operations will be presented as discontinued operations. The new guidance also requires disclosure of the pre-tax income attributable to a disposal of a significant part of the company that does not qualify for discontinued operations reporting. The Company adopted this ASU in the first quarter of 2015 and it did not have an impact on the Company's consolidated financial position, results of operations or cash flows. Revenue from Contracts with Customers (Topic 606) Section A-Summary and Amendments That Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs-Contracts with Customers (Subtopic 340-40). In May 2014, the FASB issued ASU No. 2014-09, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. The new guidance is effective for the Company beginning in fiscal 2017. Early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is currently evaluating the effect that ASU No. 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. Compensation-Stock Compensation (Topic 718) Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. In June 2014, the FASB issued ASU No. 2014-12, which clarifies the proper method of accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. Under the new guidance, a performance target that affects vesting and could be achieved after completion of the service period should be treated as a performance condition under FASB Accounting Standards Codification (ASC) 718 and, as a result, should not be included in the estimation of the grant-date fair value of the award. An entity should recognize compensation cost for the award when it becomes probable that the performance target will be achieved. In the event that an entity determines that it is probable that a performance target will be achieved before the end of the service period, the compensation cost of the award should be recognized prospectively over the remaining service period. The new guidance is effective for the Company beginning in fiscal 2016. Early adoption is permitted. Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial position, results of operations or cash flows. Preparation of Financial Statements - Going Concern (Subtopic 205-40), Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. In August 2014, the FASB issued ASU No. 2014-15, which states that under GAAP, continuation of a reporting entity as a going concern is presumed as the basis for preparing financial statements unless and until the entity’s liquidation becomes imminent. If and when an entity’s liquidation becomes imminent, financial statements should be prepared under the liquidation basis of accounting. Even when an entity’s liquidation is not imminent, there may be conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern. In those situations, financial statements should continue to be prepared under the going concern basis of accounting, but the amendments in this ASU should be followed to determine whether to disclose information about the relevant conditions and events. The new guidance is effective for the Company beginning in fiscal 2017, and for annual periods and interim periods thereafter. Early adoption is permitted. The Company will evaluate the going concern considerations in this ASU; however, management does not currently believe that the Company will meet the conditions that would subject its financial statements to additional disclosure. Income Statement-Extraordinary and Unusual Items (Subtopic 225-20), Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. In January 2015, the FASB issued ASU No. 2015-01, which eliminates the concept of extraordinary items in an entity’s income statement. Extraordinary classification outside of income from continuing operations was previously considered only when evidence clearly supported its classification as an extraordinary item. Extraordinary items were events and transactions that were distinguished by their unusual nature and by the infrequency of their occurrence. The ASU eliminates the need to separately classify, present, and disclose extraordinary events. The disclosure of events or transactions that are unusual or infrequent in nature will be included in other guidance. This new guidance is effective for the Company beginning in fiscal 2016. Early adoption is permitted. Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial position, results of operations or cash flows. Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. In April 2015, the FASB issued ASU No. 2015-03, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. This new disclosure guidance is effective for the Company in fiscal 2016. Compensation-Retirement Benefits (Topic 715): Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets. In April 2015, the FASB issued ASU No. 2015-04, which provides a practical expedient that permits the entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply that practical expedient consistently from year to year. The practical expedient should be applied consistently to all plans if an entity has more than one plan. If a contribution or significant event (such as a plan amendment, settlement, or curtailment that calls for a remeasurement in accordance with existing requirements) occurs between the month-end date used to measure defined benefit plan assets and obligations and an entity’s fiscal year-end, the entity should adjust the measurement of defined benefit plan assets and obligations to reflect the effects of those contributions or significant events. However, an entity should not adjust the measurement of defined benefit plan assets and obligations for other events that occur between the month-end measurement and the entity’s fiscal year-end that are not caused by the entity (for example, changes in market prices or interest rates). This new guidance is effective for the Company in fiscal 2016. Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial position, results of operations or cash flows. Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. In April 2015, the FASB issued ASU No. 2015-05, which provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. This new guidance is effective for the Company in fiscal 2016. Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial position, results of operations or cash flows.
Derivatives	The Company uses derivative instruments primarily to reduce its exposure to changes in currency exchange rates and interest rates. When the Company enters into a derivative contract, the Company makes a determination as to whether the transaction is deemed to be a hedge for accounting purposes. For a contract deemed to be a hedge, the Company formally documents the relationship between the derivative instrument and the risk being hedged. In this documentation, the Company specifically identifies the asset, liability, forecasted transaction, cash flow, or net investment that has been designated as the hedged item, and evaluates whether the derivative instrument is expected to reduce the risks associated with the hedged item. To the extent these criteria are not met, the Company does not use hedge accounting for the derivative. The changes in the fair value of a derivative not deemed to be a hedge are recorded currently in earnings. The Company does not hold or engage in transactions involving derivative instruments for purposes other than risk management. ASC 815, "Derivatives and Hedging," requires that all derivatives be recognized on the balance sheet at fair value. For derivatives designated as cash flow hedges, the related gains or losses on these contracts are deferred as a component of accumulated other comprehensive items. These deferred gains and losses are recognized in the period in which the underlying anticipated transaction occurs. For derivatives designated as fair value hedges, the unrealized gains and losses resulting from the impact of currency exchange rate movements are recognized in earnings in the period in which the exchange rates change and offset the currency gains and losses on the underlying exposures being hedged. The Company performs an evaluation of the effectiveness of the hedge both at inception and on an ongoing basis. The ineffective portion of a hedge, if any, and changes in the fair value of a derivative not deemed to be a hedge are recorded in the condensed consolidated statement of income.
Fair Value Measurement	The carrying value of long-term debt obligations approximates fair value as the obligations bear variable rates of interest, which adjust quarterly based on prevailing market rates. The Company uses the market approach technique to value its financial assets and liabilities, and there were no changes in valuation techniques during the first three months of 2015. The Company's financial assets and liabilities carried at fair value include cash equivalents, banker's acceptance drafts, and derivative instruments used to hedge the Company's foreign currency and interest rate risks. The Company's cash equivalents are comprised of money market funds and bank deposits that are highly liquid and easily tradable. These investments are valued using inputs observable in active markets for identical securities. The carrying value of the banker's acceptance drafts approximates their fair value due to the short-term nature of the negotiable instruments. The fair values of the Company's interest rate swap agreements are based on LIBOR yield curves at the reporting date. The fair values of the Company's forward currency-exchange contracts are based on quoted forward foreign exchange rates at the reporting date. The forward currency-exchange contracts and interest rate swap agreements are hedges of either recorded assets or liabilities or anticipated transactions. Changes in values of the underlying hedged assets and liabilities or anticipated transactions are not reflected in the table above. The Company recorded contingent consideration as part of its acquisition of a European manufacturer on December 30, 2013. The fair value of the contingent consideration is based on the present value of the estimated future cash flows. Changes to the fair value of the contingent consideration are recorded in SG&A expense.

- Definition

Disclosure of accounting policy for determining an entity's fiscal year or other fiscal period. This disclosure may include identification of the fiscal period end-date, the length of the fiscal period, any reporting period lag between the entity and its subsidiaries, or equity investees. If a reporting lag exists, the closing date of the entity having a different period end is generally noted, along with an explanation of the necessity for using different closing dates. Any intervening events that materially affect the entity's financial position or results of operations are generally also disclosed.
