IMPROVEMENTS IN OR RELATING TO DRAW HOOKS OF A DOBBY

摘要

A process and apparatus for reading-in of a perforated pattern card by means of reading needles for controlling the draw hooks of a dobby. An operating lever is flexibly coupled to the reading needles so as to effect the position of the draw hooks. The reading needles, when they fall into a hole of the pattern card, bring the operating lever within reach of a power drive which, without effecting the reading-in position of the needles, initiates an amplified power control of the draw hooks through the operating lever.
