Auxiliary device for a semi-automatic warp thread drawing-in device for mechanical looms

摘要

The auxiliary device for a semi-automatic warp thread drawing-in device instructs the person carrying out the drawing-in of the warp threads from which heald frame (18) of a stack (16) of heald frames the heald (24) into which the next warp thread must be drawn must be selected. For this purpose, the relevant heald frame (18.3) is raised by means of apparatuses (17 or 25) so that the thread eyes (23') of the healds (24') of this heald frame (18.3) reach a different level (B) from the thread eyes (23) of the healds (24) of the other heald frames of the stack (16) of heald frames. The apparatuses (17, 17a, 25) have, for every heald frame (18), separately controllable adjusting members (19/20). <IMAGE>
