Embodiment Construction

[0032] Figure 1 shows a cutting system for a sheet of paper 5 in a longitudinal cutting station of a paper processing machine. The longitudinal paper cutting station consists of a longitudinal cutting device 2 comprising an upper cutter 3 and a lower cutter 4 which tangentially cuts a sheet of paper passing between the lower cutter and the upper cutter.

[0033] A supporting shaft 6 is arranged in each case in front of the longitudinal cutting device 2 and behind the longitudinal cutting device 2 in order to support the sheet 5 in the transverse direction, ie in a plane perpendicular to the drawing plane. Due to the width of the paper 5, sufficient stability of the support shafts 6 over the entire width of the paper is required, so these support shafts 6 are made with a relatively large diameter of up to 150 mm. Due to the large diameter of the support shafts 6 , these support shafts 6 can of course only be arranged at a correspondingly large distance from the tangent point of...

Abstract

To provide a support device 10 for band-like material, particularly paper band-like material, in the slitter of a machine for cutting the band-like paper 5, particularly for cutting paper in paper processing industries. This support device 10 comprises at least one of support shafts 11 and at least one of pivotally supporting means for rotatably supporting the support shafts. The support device is formed on the outside of the rotating axes of the support shafts 11. Additionally, the invention relates to a support device and a cutting system for the band-like paper 5, particularly for paper and machine of paper packing industry.

Description

technical field [0001] The invention relates to a support device for sheet material, especially paper, for a cutting device of the sheet material, in particular for a longitudinal cutting device of a machine in the paper processing industry. The invention also relates to the use of a support device and a cutting system of a sheet material, especially paper, and a machine in the paper processing industry. Background technique [0002] SLK is a paper format cutting machine proposed by the applicant. A number of sheets are conveyed together in front of the longitudinal cutting machine and are cut in the longitudinal cutting device into strips having a width of 210 mm, eg as specified by DIN (German Industrial Standard) A4 paper. The longitudinal cutting device is a fixed longitudinal cutting device with a tangential cutter. The longitudinal cutter station of such a paper processing machine consists of an upper cutter and a lower cutter, through which at least one sheet passes...
