<p>A sewing machine for use with a template capable of holding together two or more layers of fabric that are to be stitched together, the template having a groove shaped according to the required stitching profile and engageable with a guide member projecting upwardly from a baseplate of the sewing machine, the guide member having a hole through which a needle mounted on the sewing machine passes to effect a stitching action, the template further comprising relatively movable sections for forming at least one pleat in an upper layer of fabric and so imparting fullness to that layer as the sections are moved together, the end of the pleat extending across the groove. The machine includes diverting means for engaging the pleat, the diverting means being secured in a fixed position on the sewing machine head to lie above the guide member. The diverting means has a needle passage aligned with the needle passage hole through the guide member. The machine includes drive means for effecting movement of the template relative to the guide member to drive the template so that the groove moves along the guide member. The drive means comprises a drive wheel having a periphery capable of engaging a drive edge of the template, means for rotating the drive wheel to cause this to move the template in a normal direction, and means for reversing the direction of rotation of the drive wheel to cause this to move the template in a reverse direction.</p> |
