Embodiment Construction

[0040] according to figure 1 , the transverse cutting device 11 and the blade device 10 according to the present invention are part of the pulp dryer 100 . figure 1 Only a portion of the pulp dryer 100 is shown, more specifically the press section 110, cutting section 112 and sheet section 114 of the dryer. In pulp dryer 100, a fibrous web formed from cellulosic pulp arrives as a uniform, full-width web onto a slitting machine (slitting machine) 122, and the fibrous web is cut in the direction of travel of the fibrous web In other words, the fibrous web is cut into a plurality of individual webs in the machine direction. Thereafter, these parallel fiber webs are cut into pulp sheets in the transverse direction using the transverse cutting device 11 according to the invention. The pulp sheets are stacked on the lamella portion 114 in stacks of pulp sheets. according to figure 1 , the transverse cutting device 11 according to the present invention comprises the main componen...

Abstract

A blade apparatus and a transverse cutting machine. In a blade apparatus in a cutting roller of a sheet cutter of a pulp dryer, the cutting roller comprising a roller shell recess comprising opposingsurfaces for the blade apparatus and fastening elements for fastening the blade apparatus to the opposing surfaces of the cutting roller. The blade apparatus comprises: an elongated cutting blade forcutting a pulp board, adapted to be fastened in a recess of a cutting roller; an elongated guide bar adapted to support the cutting blade on an opposite surface, the guide bar comprising an opening for the fastener; a fastener comprising a head for fastening the guide bar to the opposite surface by means of the fastener through the opening in the guide bar; and an adjusting element for positioningthe guide bar in the radial direction of the cutting roller. The bar includes a longitudinal blade recess of the cutting blade. Longitudinal blade recesses are formed on opposite sides of the head ofeach fastener from the guide bar, adapted to lock the cutting blade between the guide bar and the opposite surface by means of frictional locking.

Description

technical field [0001] The present invention relates to a blade arrangement (arrangement, arrangement, arrangement) in a cutting roll of a sheet cutter (paper cutter) of a pulp dryer, the cutting roll comprising a roll shell recess ), the roller shell recess includes a counter surface (counter surface, opposing surface) for the blade device and a first fastener for securing the blade device to the opposite surface of the cutting roller, the blade device include: [0002] - an elongated cutting blade for cutting pulp sheets, the elongated cutting blade being adapted to be fastened in the recesses of the cutting roll; [0003] - an elongated guide strip adapted to support the cutting blade against an opposing surface, the guide strip comprising openings for fasteners; [0004] - a fastener comprising a head for fastening the bar to an opposing surface by means of the fastener through an opening in the bar; and [0005] - an adjustment element for positioning the guide bar in ...
