<p>The continuous belt (1), for use in a papermaking machine and the like, has at least two longitudinal couplings (5) which extend across the belt, with coupling eyelets at their facing sides. The couplings (5) are assembled together so that their eyelets overlap to form a channel for the insertion of a coupling wire. The couplings (5) are tubes to form the coupling eyelets. Complementary cut-out sections (6) to the eyelets take them when the coupling tubes (5) are secured together. A pair of coupling tubes (5) are next to each other with the cut-outs (6) and eyelets only at their facing longitudinal sides. The couplings (5) are held to the ends (2) of the belt (1) by filaments (3) around them. Reinforcement wires are incorporated into the couplings (5). The coupling wires through the eyelets are held in place by the filaments around them, holding the couplings in place at the ends of the belt. The filaments (3) are part of the woven/knitted belt (2) structure. The whole belt can be composed of couplings which are locked together by coupling wires. The coupling tubes (5) have an oval cross section, with a flat upper and lower side, flush with the surfaces of the belt (1). The couplings are of extruded polymer materials, with an inner reinforcement. They have a thickness of 1-4 mm and extend along the belt line by 3-25 mm. An Independent claim is included for the prodn. of the belt couplings (5) where they are initially shaped and then the cut-out sections (6) are stamped out, cut out or milled. Preferred Features: To produce the couplings (5), a tubular reinforcement is given a plastics cladding, or the couplings (5) are extruded. A further Independent claim is included for a belt where the couplings are laid together at their longitudinal sides, and neighboring couplings are locked together by an inserted coupling wire through the channel formed by their eyelets.</p> |
