Process for producing a topographical pattern in or on a papermachine fabric.

摘要

Process for producing a topographical pattern on or in a fabric (26) of papermaking machine, which is produced by a rotary screen (28) having a topographical pattern (18-24) polymer and wherein the polymer is fed the fabric (26) of paper through the rotary screen machine (28), wherein the rotary screen (28) extends only over a partial width of a support structure of the fabric and that, to form the topographical pattern ( 18-24) of polymer on the support structure, the rotary screen (28) is moved relative to said support structure such that the polymer topographical pattern is formed with respect to the width of the support structure for several topographical pattern sections juxtaposed with each other, at least in the plane of the support structure, an offset of 0.1 mm or less.
