A sewing machine includes a support surface for two plies of material to be sewn together and a sewing mechanism that is attached to the support surface and is in operative connection with a machine controller, wherein a plate element positioned between the two material plies is arranged in the material feed area thereof. A vertical adjustment device for the plate element that is actuatable by the machine controller adjusts a vertical distance between the support surface and the plate element, and thus also influences the feed of material to the sewing mechanism. The vertical adjustment device is equipped with an electromagnet for adjusting the position of the plate element. The plate element is equipped with a magnet, which cooperates with the electromagnet.

A flexible support receiver comprising a base, a sewing flange, and a snap fit flange. The base is configured to receive one or more support poles or other support device. A first sewing flange and a second sewing flange are radially disposed around the perimeter of the base. The support receiver may contain vented openings. A sewing fixture aids to position hardware with a circular sewing flange such that a sewing machine places a circular stitch line relative to the central axis of the hardware.

An edge stitching device for a fly includes a table on which the fly is placed, a clamping device which sandwiches the fly in cooperation with the table, a sewing machine which edge-stitches an edge of a fly body, a cutter provided in the sewing machine and cut the fly body to form the curved side, and a clamping device conveying device which conveys the clamping device in a sandwiched state. The clamping device conveying device continuously performs: pre-edge-stitching conveyance, in which the clamping device is linearly conveyed toward the sewing machine in a state where the fly is sandwiched before edge stitching; and edge stitching conveyance, in which the clamping device is conveyed in a state where the fly is sandwiched during the edge stitching. In the edge stitching conveyance, the clamping device is conveyed in accordance with a shape of the curved side formed by the cutter.

An invention is provided for use with sewing machines that either allows for a table to be attached or to use the integral table built into certain manufacturers of sewing machines. The table has provisions to slidably secure guide plates thus allowing for more consistent seam lines when in use. The guide plates have provisions to provide clearance to the presser foot when moved closer together. The table has ruled markings to more precisely set the seams with the use of the guide plates. The guide plates can be used with sewing machines with integral tables by the addition of a pair of support plates secured to the bottom of the table, and a pair of slide plates separated by sleeves. The slide plates may have graded markings as depicted on the table.
