Abstract
An automatic border sewing system having a pre-feed assembly for feeding a length of material for forming a mattress border. A feed and cut assembly feeds the border material into a sewing station for forming mitered corners in the border material and thereafter cuts the border material to form a border of a desired length. The mitered border is moved to a closer station for closing the leading and trailing edges of the border.
Claims32
A method of automatically forming a mattress border, comprising:
- (a) providing a workpiece of a desired length for forming the border;
- (b) moving the workpiece along a path of travel adjacent a sewing station;
- c) feeding a selected portion of the workpiece into the sewing station;
- d) forming a mitered corner in the selected portion of the workpiece at the sewing station and removing the selected portion of the workpiece from the mitering station;
- (e) repeating steps c-d until four mitered corners are formed in the work piece;
- and
- (f) closing the workpiece to form a completed border.
An automatic border sewing system, comprising:
- a pre-feed assembly for feeding a length of border material to form a border;
- a feed and cut assembly that receives, measures and cuts the border from the length of border material, and which includes a drive assembly, a cutting blade, and a sewing station into which a corner portion of the border are fed for forming a mitered corner in the border;
- a closer station downstream from the feed and cut assembly, having a closer sewing head for sewing a leading and trailing end of the border and a clamp assembly for holding the border as the leading and trailing ends of the border are sewn;
- and
- a control system.
A system for automatically measuring, cutting, closing and forming mitered corners in a mattress border, comprising:
- a pre-feed assembly adapted to supply a length of material to form the border;
- a drive assembly downstream from the pre-feed assembly for measuring and feeding the desired length of material to the border and for selectively feeding corner portions of the border to a sewing station;
- said sewing station including a sewing head adapted to engage and sew mitered corners along the corner portions of the border, and a sewing detector for monitoring a sewing operation;
- a closer station downstream from said sewing station for closing leading and trailing ends of the border;
- and
- a control system for monitoring and controlling operation of the system.
