Problems solved by technology

[0005] However, when using the conventional button sewing machine described in the above-mentioned No. 4198023 communique to perform the button sewing process and the thread winding sewing process, it is necessary to manually change the position of the button fabric holding device.
Especially when the buttoning process is finished and the next winding sewing process is transferred, the fabric with lining is first removed from the fabric holding part, and on this basis, the position of the fabric holding device with lining is changed, and then the fabric with lining is removed. The button fabric is re-set (reset) on the buckle fabric holding device after the position has been changed. In this case, many and troublesome manual operations are required when transferring from the button sewing process to the winding sewing process. (Sewing worker) homework
[0006] Therefore, although the button sewing process and the thread winding sewing process can be performed with one sewing machine, the above-mentioned many and cumbersome operations are required when the two processes are switched, so the workability and work efficiency of the predetermined button sewing cannot be sufficiently improved.

Abstract

The present invention relates to a button sewing method and a sewing machine for sewing buttons, wherein the button sewing method comprises the following continuously-implemented steps of: disposing an outer button, a lining button and a cloth on a carrier plate; enabling the two buttons to independently move and simultaneously sewing the buttons on the cloth; keeping the cur-off state of a cut-off end portion of a sewing thread for sewing buttons and keeping the state of the outer button and the cloth; enabling two button supporters to move away from each other; overturning the two buttons to be in a vertical posture; folding the end portion of the cloth hanging downwards due to overturning; repeatedly performing winding first needle motion, and winding second and third needle motions for alternatively threading at both sides of the sewing thread for sewing buttons; cutting off portion of the thread wound at the periphery of the outer button after winding second needle motion; and enabling the two supporters to perform reverted return overturning, thereby enabling the two buttons to be in a horizontal or substantially horizontal posture.

Description

technical field [0001] The present invention relates to a button sewing method and a button sewing machine. The button sewing method and the button sewing machine are such as nailing outer buttons such as flat buttons on the surface side of fabrics such as men's and women's clothing, and nailing linings on the back side of the fabrics. In order to wrap the sewing thread around the button sewing thread located between the outer button and the material, wrapping sewing is performed. [0002] In order to use a sewing machine to sew the outer button and the lining button sewing to enhance its sewing fastness, and to perform winding sewing to further ensure the fastness of the button, it is generally necessary to have two processes, the buttoning process and the winding sewing process. In the process, the outer button and the lining button held on each button support body are set in a horizontal or roughly horizontal posture at the specified buttoning position, and the fabric is pl...
