Abstract
The disclosed stitching machine and method orients cooperating needle and hook components of a sewing machine in spaced horizontal alignment, and suspends flexible sheet(s) to be stitched in a generally vertical orientation between these sewing machine components, and tensions the sheet(s) to a flat stitchable condition whereby the sewing machine components might stitch interior seams through the flexible sheet(s). Horizontal and vertical slides support the cooperating sewing machine components to move along horizontal and vertical axes parallel to the suspended flexible sheet(s), and controlled drives shift them in unison along these axes as needed to trace out an intended seam pattern relative to the flexible sheet(s). A conveyor is provided with a substantially vertical run of a height in excess of the sheet(s) to be stitched when vertically oriented, to pass the sheets between the sewing machine components and hold them in the vertical orientation for stitching, and to remove them after being stitched. The disclosed invention reduces floor space previously needed for prior art stitching machines that oriented the flexible sheet(s) in a horizontal plane when being stitched.
