International ClassB65H 029/00AbstractAn apparatus is disclosed for flipping over flexible and limp planar workpieces such as fabric. The apparatus includes a primary workpiece propeller having a cylindrical means for contacting the workpiece about a central rotating axis. A slot of sufficient size to receive the workpiece is positioned in a vertical orientation beneath the primary propeller. The slot preferably has a flared upper end positioned directly beneath and in contact or near contact with the propeller. The fabric is drawn into the slot by the rotation of the propeller and follows the contour of the flared open end of the slot. The fabric enters into the slot until the trailing edge of the fabric is in contact with the primary propeller. The trailing edge of the fabric is gripped by the propeller and thereby drawn to the opposite side of the flared opening of the slot and is subsequently pulled out of the slot. The fabric has thereby been inverted so that the top of the fabric is now on the bottom.Other References
