Abstract
A method and apparatus for manufacturing wire link bands, for example for use in paper making machines, are disclosed. Several wire links or helices are arranged parallel to each other, adjacent helices having opposite pitch. The helices are simultaneously fed through a closure slot while under tension. The closure slot is so shaped as to cause each turn of each helix to be engaged between two adjacent turns of an adjacent helix, thereby to form a wire link band. The closure slot may be held stationery while the wire links are pulled therethrough, or the wire links may be held stationary under tension while the closure slot is moved along their length. A plurality of closure slots may be used to form several wire link bands in parallel, and at least one additional closure slot may then be used to combine the wire link bands into a larger wire link band or sieve. Connecting rods may also be inserted into the wire link bands and may be heat fixed before insertion.
