Abstract
A method of aligning a portion of textile fabric, whereby at least two movable gripping elements of a display device are brought alongside one another into contact with and fastened to a front edge of the portion of fabric and the gripping elements are moved substantially parallel to the surface of a display surface until the portion of fabric is laid out with one side flat on the display surface. In this case, the feed rate of the independently controllable gripping elements (2a, 2b) is so selected that the alignment of the portion of fabric (4) is variable by a feed difference (d, v) between the gripping elements (2a, 2b).
Claims19
A method of aligning a portion of textile fabric, the method comprising:
- providing at least two independently controllable and movable gripping elements of a display device are brought alongside one another into contact with and fastened to a front edge of the portion of fabric;
- moving the gripping elements substantially parallel to a display surface of the display device until the portion of fabric is laid out with one side flat on the display surface;
- adjusting a feed rate of the gripping elements so that alignment of the portion of fabric relative to the display surface is variable by means of a feed difference between the gripping elements.
An apparatus for laying out a portion of textile fabric, the apparatus comprising at least two movable gripping elements which are movable alongside one another into contact with and fastenable to a front edge of the portion of fabric, a display surface on which the portion of fabric may be laid out, said display surface having an alignment setpoint, and a control unit for controlling the gripping elements, the control unit moves the gripping elements independently of one another and varies a feed rate of the individual gripping elements while the portion of fabric is being laid out to align the fabric with the alignment setpoint.
A method for aligning a fabric, the method comprising the steps of:
- providing display surface with an alignment setpoint;
- providing first and second gripping elements independently movable across said display surface;
- connecting a first edge of the fabric to said gripping elements;
- moving said gripping elements with the fabric across said display surface;
- measuring an offset distance from a second edge of the fabric to said alignment setpoint;
- adjusting a rate of said moving of said gripping elements to minimize said offset distance.
