ABSTRACT:
A border serger, used in the bedding industry, the serger having a left-hand and a right-hand sewing head, positioned approximately in a common horizontal plane, permitting border serging of both edges of one piece of border, or simultaneous border serging of one side of two pieces of border. The respective lateral spacing of the sewing heads can be adjusted as desired, for example, by having a motor driven acme threaded screw rod connected to the left-hand sewing head. A pair of pull rollers downstream of the sewing heads are used to pull the one or two pieces of border material past the sewing heads for serging. Typically, a border may be serged only along one side for the border to be used in box springs manufacture and serged along both sides for a border to be used in mattress manufacture.
