Method to increase bond strength and minimize non-uniformities of woven two-layer multiaxial fabrics and fabric produced according to same

摘要

A papermaker's fabric formed of a woven fabric strip (16). The fabric strip (16) has a width less than a width (W) of the papermaker's fabric, a main portion (29) that is in form of a multi-layer weave comprising two or more layers of lengthwise and crosswise yarns and two lateral edges (30, 32) that are in the form of the weaves having fewer layers than the main portion. The edges (30, 32) are formed such that when the fabric strip (16) is wound around in a continuous spiral fashion to form a papermaker's fabric, the lateral edges (30, 32) overlap one another forming a spiral seam which has a number of layers equal to that of the main portion with the joining surfaces of said overlapping edges being substantially smooth.
