Problems solved by technology

Therefore, the procedure of operation and transfer of healds is complicated
[0012] (4) Since a plurality of healds are fixed by the gear belt at the position where they are conveyed to the support, it is difficult for the operator to find a fault in the healds
Moreover, if a fault is found in any one of the heddles, subsequent work to eliminate the fault is complicated by the presence of multiple healds

Abstract

A drawing in machine comprises a plurality of laths, a lath memory and a transporting mechanism. The transporting mechanism receives the laths separated from the lath memory at the heddle supplying position, and transports the heddle to the warp leading position, and transports to the lath popping position through the lath led with warps. The transporting mechanism comprises a plurality of loaders, loader guides, transporting mechanisms of constant pitch and transporting mechanisms of non-constant pitch. The loaders fix the independent lath and can be movably arranged on the loader guides. The loader guides lead the loader having lath to the warp leading position. The transporting mechanisms of constant pitch transport the loader from the heddle supplying position to the warp leading position by instant pitch. The transporting mechanisms of non-constant pitch transport the loader from the warp leading position to the lath popping position by instant pitch.

Description

technical field [0001] The present invention relates to a drawing-in machine for threading warp yarns through a harness, such as a heddle or dropper, and more particularly to the transfer of the harness from a harness feed position to a harness ejection position. Background technique [0002] Japanese Patent No. 3213813 discloses a heald transmission mechanism for automatically threading warp yarns through heddles in a drawing-in machine. [0003] The drawing-in machine disclosed in the above-mentioned patent has a heald transfer device for operatively transferring a heddle, such as a heald, between a first position where the heald is separated from its storage device and a second position where the warp thread passes through the heddle. [0004] The transfer device has a pair of top and bottom plates spaced apart from each other by a predetermined distance, a gear belt is arranged around the plates, chain links are also arranged around the plates, and four guide wheels are ...
