Embodiment Construction
[0043] figure 1 and figure 2 A first embodiment of a sawing device 10 according to the invention is shown. The saw apparatus 10 includes a saw unit 20 , a carriage system 110 , a positioning assembly 40 and a carrier unit 70 . For reasons of illustration, the operation of the sawing device 10 will be described below in connection with sawing through a paper roll 1 in order to resize the roll. like figure 1 Roll 1 shown is a standard industrial size paper roll having a roll diameter D of about 50 inches and a roll width W of about 138 inches, although the saw apparatus is also suitable for processing rolls up to 72 inches in diameter . The saw apparatus 10 according to the present invention can of course be used to cut or resize smaller rolls, and indeed can generally be used to cut very large and / or heavy cylindrical materials, including rolls and Log-shaped material.

Abstract
Apparatus for cutting an industrial-size roll of paper or other sheet material into two or more rolls. The apparatus includes a circular saw with a radius large enough to cut through such a roll in a single cut, leaving press-ready rolls that require no finish-trimming on the ends. The saw blade is mounted in a saw frame that travels along a carriage and positions the blade at any desired cutting position on the roll. The apparatus includes a support bed and load-bearing arms for supporting the weight of a large roll and keeping it in position during the cutting operation. Load / unload tables and a system of kicking cylinders guide the roll onto and off of the support bed. The saw frame is a tower that positions the saw blade above the roll at the desired cutting position, or a floor frame that positions the saw along side or beneath the roll at the desired cutting position. The apparatus further includes a finishing station for sanding the ends of cut rolls.
Description
technical field [0001] This invention relates to the field of processing large rolls of sheet material. In particular, the present invention relates to cutting such large rolls. More specifically, the invention relates to subdividing a roll of industrial size sheet material into two or more separate rolls. Background technique [0002] Paper rolls are offered in various widths for the printing industry. Often it is necessary to resize the roll from its original state, ie to reduce the width of the roll, or to cut damaged ends from the roll. The conventional method of resizing such rolls is to run the paper through a rewinder. The process entails feeding the paper through a shear that uses a blade to cut the paper to the desired width and rewinding the cut or cut material onto one or more rolls as applicable. One of the largest industrial size paper rolls has a diameter of 72 inches and a paper width of 138 inches. Rolls of this size are generally not resized on a rewind...
