Abstract
A machine for cutting damaged ends off of rolls of wound sheet material includes a saw that moves in a circular motion about the circumference of one end of the roll of material. The circular motion of the saw is coupled with a movement of the saw radially inward toward the center of the axis of the circular movement. The roll is thereby cut in ever increasing depths about its circumference. The machine is mounted on a portable hydraulic lift and controlled by a remote controller positioned a safe distance away from the saw. The machine and the roll of material can be more easily aligned through the use of an alignment track.
Claims32
A wheeled, portable paper roll-trimming machine for trimming the ends off of non-rotating rolls of paper.
A method for cutting the ends off of rolls of wound sheet material comprising:
- providing a roll of wound sheet material which is to be cut and which is rolled on a core, said roll of material having a circumference;
- providing a saw blade;
- providing a center shaft;
- substantially aligning said center shaft with said core;
- rotating said saw blade around the circumference of said roll of material while said saw blade cuts said material;
- and
- moving said saw blade toward said center shaft as said saw blade rotates about the circumference of said roll of material until an end of said roll of material has been cut off.
A roll trimming machine for cutting the ends off of a roll of wound sheet material comprising:
- a base;
- a center shaft supported by said base, said center shaft defining a longitudinal axis;
- a rotary arm mounted to rotate around said longitudinal axis of said center shaft, said rotary arm having a first and a second end;
- a saw mounted on said first end of said rotary arm;
- and
- a linear drive which is adapted to move said saw toward said longitudinal axis.
A paper cutting machine for cutting the ends off of rolls of paper comprising:
- a base;
- a saw supported by said base, said saw adapted to cut the ends of the rolls of paper;
- and
- a hydraulic lift upon which said saw is mounted.
A roll trimming machine for trimming off the ends of rolls of sheet material wound on a core comprising:
- a base;
- a center shaft rotatably mounted on said base;
- a first motor mounted on said base for rotating said center shaft;
- a rotary arm mounted to said shaft;
- and
- a saw for trimming the ends off of the rolls of sheet material, said saw mounted on said rotary arm.
A trimming machine for trimming a damaged end off of a cut table object comprising:
- a longitudinal track having two ends, said cut table object positioned on said longitudinal track adjacent one end;
- a cutting assembly positioned at an end of said track opposite said cut table object, said cutting assembly positioned adjacent the damaged end of said cut table object;
- a saw blade movably mounted to said cutting assembly and positioned selectively around a periphery of said cuttable object at a selected longitudinal distance along said track from one end, one of said cuttable object and said saw blade being rotatable around an axis parallel to said longitudinal track during cutting of said object, sand saw blade adapted to be moved radially toward and away from said axis.
