Description

A cuff rib reinforcement stitching and rolling device

Technical Field

The utility model relates to a clothing machine, in particular to a cuff rib reinforcement seaming and rolling device.

Background Art

The applicant previously disclosed a threaded sleeve production line with publication number CN212117251U, which includes a sewing machine, a feeding device, a barrel pulling device, a traction device, a cutting device, a conveyor belt device, and a rolling device. The rolling device includes two support rods and two lower clamping fingers. The upper and lower surfaces of the support rods extend outward to form convex edges, and barbs are processed on the convex edges. When the two lower clamping fingers swing inward, they are respectively located between the upper and lower convex edges on both sides of the support rods. When the two support rods are close together, they extend from the left end of the barrel section. When they are opened, the barrel section is stretched open and the right end of the barrel section can be covered on the two lower clamping fingers. When the two lower clamping fingers swing outward to clamp the right end of the barrel section, the two support rods remain in the stretched state and withdraw to drive the left end of the barrel section to roll toward the right end to form a double layer. However, after the cuff rib is sewn and folded, the double seams of the cuff rib are relatively separated, that is, when the folded seam of the cuff rib is rubbed with two fingers, the double seams of the cuff rib can slide relatively, which is not allowed under certain clothing sewing requirements, so it is necessary to improve the existing equipment.
