ABSTRACT:
An apparatus (10) for providing stitching along the edges of material panels on a semi-automatic basis includes a sewing machine (28) and a material locator assembly (30). The locator assembly (30) incorporates a guide member (62) with a predetermined guide edge for engaging the edges of the material panels prior to sewing. Sensor (46) senses the presence of a material panel in proximity with the sewing machine (28). Sensor (70) senses engagement with guide member (62) by a material panel. A clamp assembly (122) selectively immobilizes each material panel after sewing and before collection by stacker assembly (34). Preferably, air flow is directed through ports (50) formed in a portion of the working surface adjacent to the sewing machine (28) to facilitate advancement of each material panel.
