Vacuum threading device for needles - features hole for inserting needle, in which eye adjustment is automatic

摘要

A vacuum threading device is for needles and incorporates a hole, into which the needle is pushed. The adjustment of the eye occurs automatically through the slit width and an adjusting wire. The thread is cut to the desired length by means of a knife and clamped in a threaded holder. The thread end is inserted into a funnel and the threading device is joined to a vacuum source (vacuum cleaner). The thread is sucked in by means of the vacuum. ADVANTAGE - The threading process takes place automatically without the need for a good eyesight on the operators part.
