ABSTRACT:
A device for shearing, welding and aligning two sheets of thin material includes two segmented tables arranged on opposite sides of a vertically moveably welding head. Substantially parallel shears are equally spaced on opposite sides of the welding head. The sheets of material are arranged so that their uneven ends lie between the welding head and the respective shears. Clamping bars are arranged to clamp the sheets of material snugly against moveable segments within each of the segmented tables. The uneven ends are clamped in position and then sheared off. The moveable segments and the clamping bars move the two sheets of material inwardly toward the welding head. The distance that the moveable segments move slightly exceeds the distance between the welding head and respective shears so that the sheared ends overlap a preselected distance. A deflector arranged in the proximity of one of the shears assures that one of the sheets overlaps the other sheet. The vertically moveable welding head is moved downwardly into engagement with the overlapped sheets to effect a strong weld.
