Abstract
A hot wedge, automatic seam welder is disclosed. The welder is comprised of a chassis having a base plate, a motor housing and a support arm extending from the motor housing. An S-shaped guide for guiding opposing sheets of material is between the base plate and the motor housing. Disposed downstream from the motor housing, depending from the support arm, is vertically-movable suspension for a driven upper pressure roller which is occludable with a driven lower pressure roller on the base plate. Also depending from the support arm is vertically-movable and adjustable suspension for the hot wedge. A horn-shaped shroud for guiding material over and under the wedge, and for shrouding the wedge when in its disengaged mode, is disposed upstream from the wedge. Guides for performing lap welds, fin welds and hem welds, as well as many variations thereupon, are also disclosed.
