  • Device for mechanically turning over a longitudinal edge of a continuous fabric web
    Patent number: 6155188
    Abstract: A device for mechanically turning over at least one longitudinal edge of a continuous fabric web is provided with a conveyor for conveying the fabric web in the direction of the longitudinal edge and at least one edge turning device (1). The edge turning device (1) has two guide elements (2, 3), which can each be applied to one side of the fabric web in the region of a longitudinal edge section. An inner guide element (2) includes a convex guide surface (14) and the outer guide element (3) includes a matching concave guide surface (15). The opposing guide surfaces (14, 15) of the two guide elements (2, 3) are arranged in the edge turning device (1) so as to form a gap (10), whose width is at least slightly larger than the thickness of the fabric web in the region of the longitudinal edges. As the fabric web is drawn through the gap (10), the longitudinal edge of the fabric web is turned over in the desired manner.
