ABSTRACT:
A hook control apparatus for a shed forming machine comprises lift blades for lifting the hooks which are adapted to pivot in a bottom shed position between a hooking position and a non-hooking position relative to the blades. The hooks are supported in the bottom shed position on a hook bottom member and are biased towards their hooking position. The apparatus further includes one or more electromagnets for arresting the hooks in their non-hooking position relative to the blades. The electromagnets are arranged on the other side of points of reversal of the movement of the lift blades, which are remote from the respective hooks. A respective elongate control member is disposed movably in the direction of movement of the lift blades between each of the electromagnets and hooks. The end portion of each control member which is towards a respective electromagnet is in the form of an armature while provided at the opposite end portion of each control member is a mechanical arrester co-operable with the respective hook to retain it in the non-hooking position thereof.
