METHOD FOR MAKING A SCREENCLOTH OUT OF FILLED SYNTHETIC SPIRAL ELEMENTS AND THEREBY MADE SCREENCLOTH |
摘要 |
<p>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.</p> |
