Accounting Policies [Abstract]
Basis of Presentation	*Basis of Presentation* In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary for a fair presentation of results for such periods. Albany International Corp. (Albany, the Registrant, the Company, we, us, or our) consolidates the financial results of its subsidiaries for all periods presented. The results for any interim period are not necessarily indicative of results for the full year. The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in Albany International Corp.’s Consolidated Financial Statements and accompanying Notes. Actual results could differ materially from those estimates. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with “Risk Factors,” “Legal Proceedings,” “Management’s Discussion and Analysis of Financial Condition and Results of Operation,” “Quantitative and Qualitative Disclosures about Market Risk” and the Consolidated Financial Statements and Notes thereto included in Items 1A, 3, 7, 7A and 8, respectively, of the Albany International Corp. Annual Report on Form 10-K for the year ended December 31, 2017. Effective January 1, 2018, we adopted the provisions of ASC 606, Revenue from contracts with customers, using the modified retrospective method for transition as discussed in Note 2, Revenue Recognition. Accounting policies have been applied consistently to periods presented, except for the application of ASC 606, as further described in Note 2.

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.
