Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements include the accounts of the Company and Span-Canada, its wholly-owned subsidiary. Significant inter-entity accounts and transactions have been eliminated.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation Span-Canada uses the Canadian dollar as its functional currency. The assets and liabilities of Span-Canada are translated into U.S. dollars at the fiscal quarter-end exchange rate. Revenues and expenses are translated at weighted average exchange rates. The resulting translation adjustments are recorded as a separate component of shareholders’ equity in “Accumulated Other Comprehensive Income/Loss.”
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition We recognize revenue when goods are shipped and title passes to the customer. However, in the case of one customer relationship, at this customer’s request, we recognize revenue and title passes to the customer when the goods are produced.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." This ASU will supersede the revenue recognition requirements in ASC 605, "Revenue Recognition," and most industry-specific guidance. The standard requires an entity to recognize revenue in an amount that reflects the consideration the entity expects to receive in exchange for goods or services. The guidance is effective for annual reporting and interim periods beginning after December 15, 2017, with early adoption permitted after December 15, 2016, making it effective for our second quarter of the fiscal year beginning October 2018. We are currently evaluating the impact of adoption of this new standard on our consolidated financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on our financial statements upon adoption.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation We measure and recognize expense for all stock-based compensation at fair value. We have granted options to purchase common stock to some of our employees under various plans at prices equal to the market value of the stock on the dates the options were granted. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option pricing model. New shares of stock are issued upon the exercise of stock options. We do not have treasury stock. We have not made any stock option grants since fiscal year 2011.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
