Description

Technical Field

[0001] The utility model relates to the technical field of clothing machinery, in particular to a material taking and pressing foot mechanism of a pocket machine. Background Art

[0002] On the trouser pocket of jeans, you can often see a small pocket, which is called a watch pocket. When jeans first appeared as work pants, most of the wearers were workers. When working, in order to avoid scratching their watches, workers would take off their watches and put them in the small pockets of jeans. The reason why the pocket is made so small is to prevent the watch from swinging out. Nowadays, people usually use this small pocket to put coins, lighters, etc. The existing pocket sewing equipment usually includes a folding device, a feeding device, a sewing machine head and a receiving device. The folding device folds the watch pocket fabric and places it on the large pocket fabric. The material taking device then feeds the watch pocket fabric and the large pocket fabric to the sewing machine head for sewing. After sewing, the receiving device collects the sewn watch pocket fabric and the large pocket fabric.
