Wire loom dobby

摘要

Attached to a dobby for use in a loom is an actuator which is, in turn, attached to a first finger and a second finger to move them in unison in a cycle. The first and second fingers control the position of an upper hook and a lower hook. These hooks, when engaged by a knife, will raise a frame. During the first half of a cycle, the actuator positions both fingers in either an upper or lower position. In the second half of the cycle, the actuator positions the fingers in either the upper or lower position.
