Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a lining feeding device of a sewing machine. Background Art

[0002] For clothing such as jeans or high-end trousers, since the inner skin of the trouser loop is severely abraded, a small piece of non-woven fabric or cloth reinforcement is usually added to the inner side of the trouser loop to reduce the friction of the trouser loop on the skin. Therefore, a round piece needs to be placed above the needle hole of the tacking machine first, and then be sewn to the inner side of the trouser loop during the tacking process.

[0003] In order to solve this problem, many factories punch out the lining cloth in a circular shape in advance, and then put it on the feeding plate above the needle hole of the bartacking machine before manual sewing, and sew one by one. This method is feasible, but the efficiency is very low and the cost is relatively high. There are also machines that automatically feed the lining, but the overall size is long, and the trouser loop needs to be put into the machine forward, but the existing device is not convenient for sewing, and it is difficult to meet the needs of different customers.
