Abstract
A high speed stock thickener has a foraminous endless wire. The stock thickener is of the type in which an open mesh endless wire is trained over a pair of rolls and paper stock to be thickened is applied between the wire and the rolls and is carried on an inside surface of the wire for dewatering, particularly at the regions where the stock is carried between the wire and a roll. The improved wire is formed with a width greater than that of the rolls with a marginal edge of the wire extending beyond the face of the rolls. A guide belt is attached at each of the marginal edges of the wire and runs with a side wall in engagement with the end of the adjacent roll. The guide belts are attached to the wire by an adhesive bond between the backs of the belts and the adjacent wire surfaces, and by a continous thread which is sewn through each belt from the bottom of the belt and through the back thereof and into the wire.
