Abstract
A method and apparatus for sewing a cloth handle to the side panel of a mattress or box spring. The apparatus includes a modified X-Y programmable sewing machine which can sew both ends of a handle to the side panel in sequence without the necessity of removing the handle and side panel from the clamp and manually adjusting the position of the side panel. The apparatus also includes a folding jig, and a clamp with an upper lip to retain the handle in a desired position. The method includes the steps of folding the handle and placing it within the clamp on the sewing machine, and thereafter sequentially stitching each end of the handle to the side panel automatically without removing the handle from the clamp or without manual movement of the side panel.
