Patent ID: 8302649

Claim:
An infrared welding device comprising: a machine base having at least two workpiece supports for two workpieces, a distance between the workpiece supports being variable, at least one infrared radiator fixed at a movable tool holder of the machine base and introducible into a gap formed by the distance between the workpiece supports, and a program control, wherein the distance between the workpiece supports and a relative assignment of the tool holder are adjustable by the program control, and wherein the workpiece supports and the tool holder are assemblable to form a welding module transportable as closed unit and are connectable to the machine base by quick-action couplings, wherein a storage for at least two welding modules is associated with the machine base from a rear side, and wherein the welding modules received in the storage are alternatively introducible into the machine base and engageable with the quick-action couplings.
