UNI 100-1600
backUniversal – Multi-ID Core Cutter UNI 100 – 1600
For burr-free cutting of cardboard cores of different diameters on the same cutting mandrel.
The mandrel fits the whole range of diameters.
Tool change is not necessary!
Working Method and Machine Equipment
Working Method
- The tube is fed automatically onto the cutting mandrel.
- The cutting mandrel´s diameter is smaller than the inner diameter of the core an therefore suitable for the whole range of core IDs.
- The cutting length is entered at a terminal then the machine is started by a button.
- An opto-electronic sensor detects the tube leading edge.
- First a trim cut is made, next the core is divided into the corresponding cutting length programmed.
- A pusher ejects the separate pieces off the mandrel.
The machine is equipped with
- Operating Terminal for programming the required cutting length and amount of pieces.
- Auto-scanning off parent core length, the machine adapts automatically.
- Auto-scanning off wallthickness, the knife unit adapts automatically.
- Auto-adjusting guiding rollers. For cutting the machine adapts to the outside diameter of the core.
- Positionable Knife-Holder incl. circular knife and absorber unit.
- Driven Knife with speedcontrol, for cutting also heavy walled cores.
- Jet - Lubrication of knife for polished cutting surface and cooling.
- Discharging unit for cut sections. Tilting of narrow cut rings is prevented by a stabilizer.
- Tube feeding system with magazin for automatic loading of machine. The cores can be loaded ergonomically favorably onto the hopper.
- High-adjustment of loading system by electric motor.
- Cutting mandrel with easy to change nylon-bushes
- Levelling Elements for correct alignment of machine.
- Safety Devices according CE - confomity
