A sewing machine includes a contact area for two superimposed material webs, which have edges and which are to be sewn together by the sewing machine, wherein, in order to align the edges of the material webs to each other, there is a bottom guide element under the contact area for the bottom material web and a top guide element for the top material web above the contact area, wherein the guide elements are each rotatably mounted about a rotation axis. The rotation axes of the guide elements are arranged extending perpendicular to the contact area.

A forming device for forming links in the shape of a Mbius strip includes a rotation module with an inner path. The forming device has a widening for 180 rotation of a strip introduced into the rotation module. The rotation module has an inlet suitable for one end of a strip, an outlet suitable for the strip and the inner path extends from the inlet to the outlet. The widening is adapted for rotation of the end of the strip 180 about its longitudinal axis. The device also includes a gas injector positioned at the inlet of the rotation module intended to drive the strip through the inner path of the rotation module.

A resilient band for an article of apparel, formed with a first fabric secured to another more resilient fabric. The first and second fabrics are secured together by a plurality of fastening structures extending transversely to a longitudinal length of the resilient band. The first fabric presents a plurality of pleats, where a pleat in the plurality of pleats is defined by an adjacent pair of fastening structures in the plurality of fastening structures.

A method of fabricating pattern composite fabric pieces by an automatic pattern fabric article piece processing machine is described. A composite fabric sheet is fed in the processing machine onto a conveyor having a permeable belt under which is provided a vacuum chamber to retain the fabric sheet stationary while a laser cutter effects a programmed job function. The machine forms seam allowance flaps for the composite fabric pattern piece. A stitching or ultrasonic bonding machine also forms seams. In a further stage, printed matter may be applied to the allowance flaps. Glue may also be applied to the flaps and labels to some of the pattern fabric pieces. By interconnecting the seam allowance flaps of different fabric pieces, in a specific order, a fabric material article is produced.

A seat heater includes a substrate. A formed heating wire is disposed on the substrate. A sewing thread attaches the formed heating wire to the substrate. A method of fabricating the seat heater includes forming a straight heating wire into a formed heating wire having miniature wave shape, feeding the formed heating wire onto a substrate, and attaching the formed heating wire onto the substrate by sewing a thread.
