ABSTRACT:
A seam for joining the ends of a fabric to form an endless belt which can be used for papermaking, is created by attaching a continuous coil to each fabric end, the loops of the coils being preformed so that when the loops are intermeshed each loop of one coil engages or creates an interference fit, with two loops of the opposite coil. To strengthen the seam, a pin is inserted in the tube formed by the intermeshed loops.
The loops are joined by using a tool which has two channels through which the ends are brought together. The channels are formed between two plates attached to the ends of scissor arms.
