Description

TECHNICAL FIELD

[0001] The utility model relates to the field of home textile manufacturing technology, and particularly to a pull cylinder capable of controlling the width of a patch and folding two live folds at equal distances for home textile products. BACKGROUND

[0002] The sewing technology of folding a live fold on a patch is a common process in home textile products such as bedspreads, pillowcases, and cushions in recent years. Specifically, one, two, three, or more live folds are folded on a patch, and then pressed and sewn to form a multi-level effect, which is favored in the field of home textiles.

[0003] Currently, there are two conventional methods for making a second fold on a patch after folding a live fold on a patch in a home textile product: Method one is to directly measure the size with a ruler and control the live fold distance from the edge, the live fold width, and the interval by ironing. Method two is to control the live fold distance from the edge by an airplane baffle and control the live fold width and interval by a sewing machine needle position. The above methods have the following disadvantages:

[0004] 1. The size of the fold made by method one is inconsistent, the distance from the edge of the fold is inconsistent, the operation method is complicated, and the auxiliary time is too long.

[0005] 2. In the process of making a fold on a patch by method two, the flash will be tightly pressed against or separated from the baffle, which will still cause the size of the fold to be inconsistent, and the line will be bent and not straight.

[0006] Moreover, the folds pressed by the two methods are vertical, and after the production is completed, the fold needs to be ironed with the reverse process. When ironing, the reverse side of the fold is easy to be sandwiched with fabric and not easy to be completely ironed open, which affects the appearance quality of the product, cannot be continuously operated, has low work efficiency, and is not suitable for mass production.
