Abstract (en)

A stock thickener for thickening pulp and paper stock, for use in papermaking equipment, includes a pair of spaced-apart rolls (20 and 22), and a single open-mesh or foraminous endless wire (30) trained over the rolls. Stock to be thickened or dewatered is admitted to a region defined by an inside surface of the wire and is carried by the endless wire from one of the rolls to the other. The wire (30) has a width which is greater than the width of the rolls, and guide belts (70) are attached to the portions of the wire which extend beyond the roll faces (72). The guide belts (70) are attached to the wire at their backs by an adhesive (77) and by a continuous thread (75) which extends through the belt from the bottom thereof through the back and through the wire.
