A cut-and-weld device has two pairs of conveyor belts which run parallel to one another and grip and convey superimposed foils. A foil support plane is defined by the nip between the belts. A cutter is mounted between the pairs of belts and extends through the foil support plane so as to cut the foils as they pass along the plane. The blade is also heated, so that the foils are simultaneously welded together. In addition, a tension rail with an upper edge is positioned adjacent the cutter, and pushes the foils in the opposite direction out of the foil support plane, so as to tension the foils to assist the cutter in cutting the foils and to keep the cut and welded edges separate. |
