Abstract:
A machine for the production of at least a single-face lined web of corrugated board (43), comprising:two fluted rolls (2, 3) for producing a corrugation (36) on a paper web (35),a gluing device (13) for applying glue (41) to the peaks (37) of the corrugations (36) of the corrugated paper web (35),a pressing device (16) for pressing a liner web (38) on the glue (41) on the peaks (37) of the corrugated paper web (35) which rests on one of the fluted rolls (3) along a pressing zone (40),the pressing device (16) comprising a continuous pressing belt (19) which is guided along a deflection pulley (17) and another pulley (18) and which is pressed against the fluted roll (3) over the pressing zone (40) and which consists of a fabric of metal having warp threads (30a, 30b, 30c) and weft threads (31),wherein the warp threads (30a, 30b, 30c) are provided to form groups of three warp threads (30a, 30b, 30c) at a time with two outer warp threads (30a, 30c) and one central warp thread (30b), the distance b between two neighboring groups of warp threads (30a, 30b, 30c) being smaller than the width a of each group of warp threads (30a, 30b, 3c);wherein the weft threads (31) are of the same diameter and formed of a rod-type wire;wherein the weft threads (31) and the warp threads (30a, 30b, 30c) are of substantially the same high chrome nickel steel alloy, and the weft threads (31) are softer than the warp threads (30a, 30b, 30c); andwherein the weft threads (31) have notches (33), in each of which a warp thread (30a, 30b, 30c) is disposed.
