Abstract
A fabric component pickup apparatus or the like having first and second fabric gripping elements defining first and second opposed gripping lines in the plane of the face of the fabric component, the fabric gripping elements adapted for movement relative to each other essentially in the plane with simultaneous components of motion closing the distance between the gripping lines and displacing one gripping line laterally in the plane of the fabric at an angle to the closing motion. As the fabric lying between gripping lines is tensioned by the component of lateral displacement motion of the gripping elements, the fabric is simultaneously gathered by the component of closing motion. In one preferred embodiment, an air blast is directed through the porosity created by tensioning the fabric to impinge upon the underlying layer of fabric.
