Abstract: ABSTRACT An interlocking frame for selective engagement with a plurality of adjoining interlocking frames is presented herein. The frame includes a frame body that defines an interior portion at least partially enclosed by a plurality of interior walls, a front face, a rear face, and a plurality of peripheral walls. The interlocking frame also includes a plurality of locking tabs each selectively and independently rotationally disposable between a retracted position and an extended position relative to the frame body. Each of the locking tabs has an arm that extends beyond the frame body when the locking tab is disposed in the extended position in order to engage with a corresponding locking slot of an adjacent frame.

Abstract: A web processing system for laser welding at least two continuous webs includes a supply station for supplying the webs and a lamination station for laser welding the webs together in a pre-determined pattern. The lamination station includes a platen having a platen surface between leading and trailing ends thereof across which the webs are conveyed and a laser welding apparatus offset from the platen surface and configured to direct a laser beam to said platen surface to laser weld the webs in the pre-determined pattern. In one aspect, the platen surface is arcuate so that the webs are maintained in intimate contact across the platen surface.
