Device and method used for seaming tubular fabric

Abstract

The invention discloses a device and method for seaming a tubular fabric. The device comprises a transfer device, a clamping plate, an overturn device and a seaming device. The transfer device comprises a transfer plate used for taking the knitted tubular fabric down and transferring the knitted tubular fabric to the clamping plate for clamping; the clamping plate comprises two semicircle ring sewing disks which can be folded in half; the seaming device is located on the side face of the clamping plate; the overturn device comprises a first tubular part and a second tubular part, the first tubular part is coaxially located under the clamping plate, and the second tubular part is coaxially located over the clamping plate; the first tubular part and the second tubular part are both connected with a negative-pressure air source. The overturn of the tubular fabric is achieved by using a pneumatic device, a device which turns over the fabric by using the mechanical principle in the prior art is replaced, and the structural complexity and fault rate are reduced.

Description

technical field [0001] The invention belongs to the technical field of circular knitting machines, in particular to a device and method for sewing tubular fabrics. Background technique [0002] After the circular hosiery knitting machine has knitted the tubular fabric, it often needs to stitch the tubular fabric. In the prior art there are devices for picking up the knitted tubular fabric of a circular hosiery knitting machine and transferring it to a sewing or crocheting station, where a sewing or crocheting station is provided. A weaving head, through which the sewing or crocheting head tubular fabric is seamed. Typically, the pick-up device picks up the fabric from a circular hosiery knitting machine and transfers it to the transport device, optionally by respectively engaging the knitting loops on the end row of the fabric so that the half row of stitches of the end row of said fabric is knitted Knitting loops facing the other half-row respectively before sewing or cro...

Problems solved by technology

Although this device basically meets the requirements of flipping fabrics, the overall structure of the device is too complicated, and the auxiliary sliding device often breaks down during use, resulting in machine failure or tubular fabric jamming, which is not conducive to large-scale promotion.

And the final product of the tubular fabric is facing outwards, with the suture or hook thread on the inside. During the factory quality inspection, it is still necessary to turn the tubular fabric inside out to check the stitching effect. The process of quality inspection increases labor costs
