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.
Claims18
Apparatus for forming a one-piece border for a mattress comprising:
- a feeding section for providing a length of border material along a substantially vertically oriented path of travel;
- a rewinding section downstream from said feeding station for receiving the border material;
- a sewing station, including a sewing head, positioned along the path of travel between said feeding and rewinding sections for sewing at least one faux seam in the border material;
- a folder blade for folding the border material as the border material moves through said sewing station for sewing said at least one faux seam defining the one-piece border with a gusset portion therein, by said sewing head;
- a drive system for moving the border material in a substantially vertical orientation from said feeding section, through said sewing station, and to said rewinding section;
- and
- a first active edge guide mechanism, between said feeding section and said sewing station, for maintaining the border material at a substantially fixed vertical elevation relative to said sewing station.
