Use of a latch, as a clamping element in the case of a tensioning device for a lower apron in the case of a drafting arrangement on a spinning machine

摘要

A draughting system for a ring frame is carried between pressings and has a bottom apron which can be tensioned by roller. The roller is mounted in a tensioning element which is in the form of a ratchet device. One element of the ratchet device bears against pressing and the other against the mounting rod. ADVANTAGE - The device allows the tension in the bottom apron to be adjusted accurately in very small steps.
