Abstract
The present invention concerns a method and an apparatus for quality control of textile threads, and particularly of threads produced by different spinning methods. The apparatus comprises a housing (10) containing two measurement modules. A first module comprises a double condenser (32) and its associated electronic circuit to determine uniformity of linear mass of the thread, a precision scale (31) to determine linear mass and a drive means (33). The second module comprises a device (34) and a device (37) which cooperate to determine twist and elastic recovery of the thread. A manipulator (17) allows automatic positioning of the test pieces of thread (46) admitted into the apparatus through flexible tubes (16). The apparatus offers the advantage of permitting a series of measurements to be taken and computer processed for purposes of statistical compilation and/or memory storage.
