An endless fabric, such as a papermaker's felt, composed of a series of generally parallel warp yarns and having cross machine yarns or fibers extending in a zig-zag pattern across the warp yarns. The cross machine yarns in each section of the zig-zag pattern extend at an acute angle up to 80 DEG with respect to a line normal to the warp yarns. The cross machine yarns are stabilized in their zig-zag pattern by physical or chemical means, such as by needling or heat setting, but remain adjustable thereafter in angularity with respect to the warp yarns once installed on a papermaking machine.
