Abstract
The quilting of rectangular comforter bags, mattress cover panels or other similar panels is provided without the need to premount the panel on a rectangular frame. A leading edge clamp is preattached along the leading edge of a panel and the clamp is fed from an operator station to the upstream end of a shuttle movably mounted on the frame of a programmed single needle quilting machine. Opposed belt conveyors on opposite sides of the shuttle advance the clamp and pull the panel onto the shuttle, with the belts gripping the side edges of the panel as it is pulled. A trailing edge clamp bar frictionally engages the panel to provide trailing edge securement to the panel, with the belts and leading edge clamp providing securement around the other edges to stretch the panel on the shuttle. The shuttle reciprocates longitudinally under a sewing head that moves transversely on the frame at a quilting station, while the sewing head operates to stitch a pattern in the panel. A pickup head then engages the clamp and directs it along a conveyor across an outfeed table at the top of the frame, pulling the quilted panel over the table where the clamp is released to drop the panel on the table,…
