A sewing machine for sewing a stitch into an article is provided. The sewing machine includes a support structure, a first head and a second head. The first head is coupled to the support structure and includes a coupler contained within a second actuator assembly and 360° rotatable relative to the support structure and a first stitching element rotatable with the coupler and translatable via a first actuator assembly relative to the coupler. The second head is coupled to the support structure and includes a coupler contained within the second actuator assembly and 360° degree rotatable relative to the support structure and a second stitching element rotatable with the coupler via the first actuator assembly.

A decoration lace comprises at least three or more decoration strings which are arranged side by side, and are connected to each other by sewing, where the decoration strings are connected to each other by a seam line which is formed in the shape of a zigzag in a longitudinal direction, and a top thread fed from an upper portion of the decoration string by a needle is locked by a bottom thread located under a lower portion of the decoration string to make a knot, and two threads are locked to the decoration string, thereby forming the zigzag-shaped seam line.

Regarding a method of a sewing process for a trim cover of a vehicle seat provided with a decorative band, conventionally, a decorative band made up of a covering and wadding is sewn to a member of a trim cover similarly made up of a covering and wadding. Because of this, an area where a decorative band is sewn has an increased thickness, causing discomfort when an occupant sits. To address this, in the example embodiment, a sewn covering is manufactured by sewing together coverings for a portion of a trim cover and a decorative band and sewing decorative stitching through the sewn ends, and then the sewn covering and wadding are overlaid on each other to sew their borders together. This makes it possible to reduce the thickness of an area where the decorative band is sewn and reduce the discomfort when an occupant sits.

A method for manufacturing a composite warm-keeping textile structure includes the steps of: applying an elastic gripper-puffing mechanism to perform puffing operations upon opened cotton fibers for forming at least one puffy fiber agglomerate; applying the elastic gripper-puffing mechanism to grab unit fiber agglomerates from the puffy fiber agglomerate and further to drop the unit fiber agglomerates onto a first cloth layer on an operational platform; vibrating the operational platform to have the unit fiber agglomerates to be evenly distributed over the first cloth layer, so that the unit fiber agglomerates are formed as a fiber agglomerate distribution layer adhered onto the first cloth layer; and, having a second cloth layer to cover the fiber agglomerate distribution layer, so that the first cloth layer and the second cloth layer clamps together the fiber agglomerate distribution layer in between to form the composite warm-keeping textile structure.

An apparatus has a plurality of needle assemblies. Each needle assembly has a needle defining a groove, and an attachment medium for attaching a first piece of fabric to a second piece of fabric, the attachment medium being discharged though the groove. The apparatus has a framework supporting the plurality of needle assemblies, the framework defining one or more tracks for actuating each needle assembly of the plurality of needle assemblies in at least one dimension. The apparatus has a mechanism configured to force insertion of the needle of each needle assembly of the plurality of needle assemblies through the first piece of fabric and the second piece of fabric, and trigger each needle assembly of the plurality of needle assemblies to simultaneously discharge the attachment medium through the first piece of fabric and the second piece of fabric.
