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.
Claims5
A seam for joining first and second ends of a fabric used in papermaking, without a backing material, to create an endless belt comprising:
- a plurality of first end loops attached to said first end;
- a plurality of second end loops attached to said second end;
- a first coil formed of continuous first coil loops spaced at a predetermined distance;
- second coil formed of continuous second coil loops spaced at a predetermined distance;
- and
- each said first and second coil loops engaging the respective end loops for securing the coils to the respective fabric ends;
- each coil loop having a portion disposed opposite the respective end, said portion being wider than said preselected distance to interlock the loops of one of the coils to corresponding loops of the other coil in a male-female engagement when said first and second coils are intermeshed;
- said first and second coils being arranged and constructed to form a space therebetween when intermeshed for an additional locking means.
