ABSTRACT:
A semiautomated sewing station includes an improved frame in which the stationary bed of the x-y positioner is mounted directly on coplanar machined members. The x-y positioner has a vertically movable sewing clamp which eliminates angular readjustment of the clamps when they are changed. The x-y positioner also includes a redesigned sewing clamp arm which is considerably more rigid than the prior art arm and which allows very rapid stitching, even when moving the sewing clamp arm in a non-linear manner. A quick change sewing clamp and quick change workpiece preparation group, such as a folding group, allow the operator to change the operation of the device in a rapid, convenient manner.
