A sewing machine able to gather one or more materials through a variable speed transfer disc or transfer cup. The gathering operation can assist in joining materials of different lengths without causing a warp or other unintended variation in the sewn article. The gathering operation may be used in connection with sewing of an article of footwear upper with an insole portion to form a foot-receiving cavity. During a sewing operation, a tension on the thread may be adjusted and confirmed with a display output. Similarly, an indication of pressure applied to decrease a rotational speed of the transfer disc or the transfer cup may be presented on a display output to achieve repeatability across operators and articles.

The footwear parts are at least partly connected together by stitching for forming at least part of an upper part of the footwear. The method includes providing a base layer and providing the at least two footwear parts. The at least two footwear parts are positioned on the base layer. The at least two footwear parts are fixated on the base layer in respective relative positions corresponding to predefined connected positions. The at least two footwear parts are connected with each other by an automated stitching. The at least two footwear parts in connected form to provide the footwear.

An embroidered vamp process includes the following steps: (1) designing a vamp manufacture drawing by a computer; (2) according to the design drawing of step (1), cutting different pieces of cloth into base fabric of the vamp and a splice component of the vamp respectively by a laser; (3) typesetting the splice component cut in step (2) on the base fabric, then embroidering the splice component on the base fabric according to an embroidery thread pattern of the drawing by an embroidery machine; (4) cutting out the redundant base fabric of the vamp along the edge the splice component by, once again, the laser, forming the vamp of the finished product shoe model. An embroidered vamp comprises a vamp body, said vamp body comprising the base fabric and the splice component, said splice component being embroidered on the surface of base fabric by embroidery thread.
