Abstract: A mounting assembly for mounting plastic closure elements or snaps on fabric includes a pair of parallel holding bars. Rows of closure elements are formed between the holding bars. The mounting assembly is positioned on the fabric and a sewing machine having a slide with a pair of guide bars is positioned over the holding bars. The holding bars of the mounting assembly provide a track for the sewing base during the stitching process. The base portions of the closure elements are stitched onto the fabric. After stitching the holding arms are torn off the closure elements and discarded. The sewing base includes a pair of guide bars for guiding the sewing base along the holding bars.
