Abstract
A process and apparatus for forming a mattress. A border material is fed through a sewing station to form a hem. The same material is fed through the sewing station again, at a different elevation to form a second hem and an attachment gusset. The hemmed gusset and border material then is preferably subjected to a ruffling process to form a series of pleats about the corners of the mattress border. The perimeter of the border is then closed, and the finished border is placed over a set of mattress springs and fixed in place.
