ABSTRACT:
A system for spreading and severing material utilizing a roller movable over a lower substrate and carrying with it a loop of material for spreading without tension. One or two plies are spread as a function of roller travel prior to severing from a source. If two plies are spread, severing of the loop occurs at the roller by an element movable with the roller. A second severing element is located at one end of the substrate to separate material from the source. A top platen carries a removable substrate having thereon multiple patterns. The patterns are defined by a resistance wire having thermal expansion joints and carried by stand-off insulators mounted on the removable substrate. When the wires are brought into contact with the material on the lower substrate, severing occurs. Multiple cycles of spreading and severing may occur prior to removal of the lower substrate.
