A bending resistant part of an endless multilayer fabric for densifying paper materials is placed on a trimming part; to thereby prevent cutting of a fabric at the trimming part. Also oblique movement and dropping off a guide protrusion is prevented. Particularly, a bending resistant part is formed by filling a polyurethane resin in internal structure of an endless fabric of trimming part of the width direction of the fabric woven with arranging at least three layers of weft. A guide protrusion molded from similar polyurethane is arranged on the bending resistant part by fusion. Cutting caused by bending and wearing of the fabric near the guide protrusion is prevented.
