Embodiment Construction

[0028] Embodiments of the present invention will be described below with reference to the drawings. exist figure 1 Among them, the waste paper processing device 1 as a kind of paper machine is equipped with: a papermaking device 2, which performs a papermaking process of making a strip-shaped wet paper 100; a drying device 4, which performs drying of the strip-shaped wet paper 100 The drying process; the white water storage part 5, the upper part of which is open, stores the filtrate flowing out from the papermaking process; and the control device controls each part (illustration omitted).

[0029] The waste paper processing apparatus 1 may provide a dehydration process between a papermaking process and a drying process. The dehydration process includes a dehydration belt made of felt. In addition, in this embodiment, the webs of the wet paper 100 and the desiccated paper 101 obtained by papering the pulp suspension will be described as an example. The ribbon-shaped article...

Abstract

The invention provides a band-shaped object cutting device and a band-shaped object heating device. In the band-shaped object cutting device, a conveying part for cutting (520) stops conveying dry papers (101) under the state of clamping the dry papers (101) in the cutting control, so that the dry papers (101) conveyed from an upstream conveying part (510) are detent to being a ring on the conveying path, and after the cutting control, the dry papers (101) can be conveyed with detention removing speed, faster than the set speed. A downstream conveying part (540) conveys the dry papers (101) with a speed similarly equal to the set speed in normal control, and stops with the conveying part for cutting (520), and conveys the cut thin pieces to the downstream with a discharging speed faster than the set speed after cutting the dry papers (101). The control part adjusts the stop period and the detention-removing speed of the conveying part for cutting (520) in the cut control based on the increasing and decreasing of the set speed of the upstream conveying part (510).

Description

technical field [0001] The present invention relates to a strip cutting device, and relates to a technique for cutting strip-shaped paper in a paper machine such as a waste paper recycling device for recycling waste paper. Background technique [0002] Conventionally, such a technique includes, for example, the technique described in Japanese Patent Publication No. 5906547. This is a cutting device of a waste paper recycling processing device, which cuts the strip-shaped paper after papermaking into recycled paper of a specified size. The strip-shaped paper is conveyed in the longitudinal direction by the conveying unit, and is cut by the paper cutter in a direction intersecting the conveying direction. The conveying unit includes a conveying roller disposed upstream of the cutter in the conveying direction of the strip of paper, and a pinch roller disposed opposite to the conveying roller and sandwiching the strip of paper between the conveying roller and the conveying rol...
