ABSTRACT:
A small cloth vise in a sewing machine arranged for the automatic application of small pockets applied on blue-jeans or on other similar garments by two fixing seams where at least on one side the seams are not parallel, comprising a central element, a cylinder fixed to the element, a small plate which transmits motion driven by the cylinder, a first blade placed under the central element for displacement in proximity to the seams operatively connected to the small plate, and first and second levers having ends connected to the blade corresponding to the side where the seams are not parallel, the first lever effecting a displacement larger than that of the second lever for causing the blade to rotate and thus to translate in sequence.
