摘要

A method for manufacturing a belt of a type suitable for use in extended nip (shoe) presses of a papermaking machine, which comprises the steps of: (a) closing, between the upper and lower platens (1,2), of a platen press, an insert plate (3), a polymer sheet (7), and part of an elongate fabric base, e.g. an endless fabric (4) held taut between rolls (5); (b) opening the platen press after a time sufficient to melt the polymer and force it, in liquid form, into the structure of the fabric base; (c) advancing the fabric base in the platen press to the point where fabric, as yet untreated with polymer, is adjacent to the insert plate; (d) inserting polymer sheet into the platen press, closely butting it to the melted polymer; and (e) repeating steps (a) to (d) until the entire length of the fabric base has been coated and impregnated with polymer. <IMAGE>
