Abstract
The sieve belt is comprised of a multiplicity of helices made of thermosettable synthetic resin material which are interlocked with each other by inserting a plurality of pintle wires into the channels defined by the overlapping helices. For controlling the air permeability of the sieve belt, the hollow interiors of the helices are filled with a filler material comprised of crimped synthetic filaments.
Claims10
A sieve belt comprised of a plurality of helices made from thermoset synthetic resin material with adjacent helices intermeshed so that the windings of one helix enter between the windings of the adjacent helix, a pintle wire disposed in each of the respective channels formed by the intermeshed windings of adjacent helices and a filler material within the hollow interior of each of the helices, said filler material being comprised of crimped or undulating filaments.
A method for producing a sieve belt comprising filling the interior of a plurality of helices with a filler material, intermeshing a plurality of helices so that the windings of one helix are disposed between the windings of an adjacent helix to define a channel and inserting a pintle wire through each channel.
