Abstract
A slitting machine for removing a strip from a sheet of material. The slitting machine has a blade assembly with first and second cutting blades, and a perforating blade arranged between the first and second cutting blades. The first and second cutting blades are arranged to cut the sheet of material to define the strip and the perforating blade is arranged to perforate the sheet of material to define an end of the strip.
Claims12
A slitting machine for removing a strip from a sheet of material, the slitting machine comprising:
- a blade assembly comprising:
- first and second cutting blades configured to cut the sheet of material to define the strip;
- a perforating blade arranged between the first and second cutting blades, the perforating blade configured to perforate the sheet of material to define an end of the strip, the perforating blade having a greater diameter than the first and second cutting blades;
- and
- a mechanism configured to adjust a distance between the blades and the sheet of material in order to selectively engage the cutting blades and/or the perforating blade with the sheet of material, the cutting blades and perforating blade being coupled to a shaft, and the mechanism being configured to adjust the distance by moving the shaft relative to the sheet of material.
A blade assembly for a slitting machine, the blade assembly comprising:
- first and second cutting blades configured to cut a sheet of material to define a strip;
- a perforating blade arranged between the first and second cutting blades, the perforating blade configured to perforate the sheet of material to define an end of the strip, the perforating blade having a greater diameter than the first and second cutting blades;
- and
- a mechanism configured to adjust a distance between the blades and the sheet of material in order to selectively engage the cutting blades and/or the perforating blade with the sheet of material, the cutting blades and perforating blade being coupled to a shaft, and the mechanism being configured to adjust the distance by moving the shaft relative to the sheet of material.
A method for removing a strip from a sheet of material using a slitting machine, the method comprising:
- feeding a sheet of material into the slitting machine, the slitting machine comprising:
- a blade assembly comprising:
- first and second cutting blades configured to cut the sheet of material to define the strip;
- a perforating blade arranged between the first and second cutting blades, the perforating blade configured to perforate the sheet of material to define an end of the strip, the perforating blade having a greater diameter than the first and second cutting blades;
- and
- a mechanism configured to adjust a distance between the blades and the sheet of material in order to selectively engage the cutting blades and/or the perforating blade with the sheet of material, the cutting blades and perforating blade being coupled to a shaft, and the mechanism being configured to adjust the distance by moving the shaft relative to the sheet of material;
- engaging the first and second cutting blades to cut the sheet of material to define the strip;
- and
- engaging the perforating blade at the end of the strip to perforate the material at the end of the strip.
