Abstract
A pickup device for a piece of sheet-form flexible fabric or the like includes first and second fabric gripping elements that come together at the face of the fabric piece to grip a localized portion of the fabric, a support for resiliently biasing the fabric gripping elements together in a gripping position, and an actuatable separator for applying force to overcome the biasing to move the fabric gripping elements apart. Upon deactuation of the separator, the support is adapted to resiliently return the gripping elements to the gripping position. A pickup system and method for loosening and removing a single face piece of fabric from a stack of pieces aligned at an edge are also described in which a vacuum stabilizing system is combined with a jet directing air under the raised edge of a fabric piece.
