Saumbildung für ein Papiermachergewebe.

摘要

A spiral seam construction for lower caliper, multi-layer papermaking fabrics. The fabric has two opposed ends (2,4), each of which is provided with a coil member (6). The coil members (6) have a plurality of headcurves (14,16) which are interconnected by a plurality of winding legs (18,20). Each of the winding legs has a cross-section in which the vertical dimension is less than the horizontal dimension, whereby it is possible to use a larger seaming pintle without an associated increase in seam caliper. The winding legs (18,20) determine the maximum caliper of the seam, and the seam does not exceed the final fabric caliper.
