Abstract
The insertion of thread into a yarn tester is accomplished by a mechanism that includes a clamp (3) for the thread end and an insertion arm (14) mounted for pivoting movement about a fixed axis to contact a portion of the thread above the clamp and swing a loop portion of the thread down into the space between feed rollers and to present the loop to a take-over nozzle (13). The thread is transferred from the insertion arm to the nozzle (13) and is fixed until transfer in the clamp (3), so that the thread transfer takes place in the form of a loop. Consequently, the insertion arm (14) need have no special thread clamp and can be of correspondingly simple design. The pivoting movement of the insertion arm (14) requires only a simple drive, and the take-over of the loop-shaped thread (F) by the take-over member is carried out without difficulty.
