Means for controlling knife oscillations and hook movements in a loom dobby.

摘要

An improved dobby uses linkages for controlling the oscillations of the fixed and mobile knives about their axes which comprise first levers fixed to the knives, second levers fixed to control shafts, and connecting rods which link said first and second levers together to form an articulated parallelogram.

In this dobby, the hook operating rods are controlled by the same shafts which control the knife oscillations, by means of an articulated joint.
