Why Do You Need a Frame Type Slitting Machine?

In our past working experiences, the turret rewinding diameter is almost less than 1000mm.

It is a threshold to be more than 1000mm diameters for roll slitting machines in the field.

More than 1000mm, means the more functional problems need to be resolved.

The first problem is that the machine must be larger in size especially since the bigger tall machine frame is not friendly to operational labor.

The second problem is that the motor power must be increased at least two times of the original motor power.

A bigger rewinding diameter means a bigger power force for rotating.

The third problem is all the differential friction shaft in the world is mainly applicable to rewinding diameter to 800mm, more than that, the friction ring journey is limited, which means the rewinding would not be tight anymore.

The fourth problem is that the machine frame should be reinforced and strengthened because of the large slitting force that will appear during operation.

And normal roll slitter rewinder machine can’t bear such big heavy mother rolls in high speed running.

The fifth problem is the finished roll unloading.

Mainly the finished slitting rolls with a diameter of 1200mm, it is heavy to unload to the floor. Even with the help of the hoise or the frame rack, it is still adequate.

With our bridge type slitter rewinders, the finished material could be unloaded to the floor easily. To reduce the labor working strength and working hurt risks.

How does slitting process work?

The slitting process involves cutting a large roll of material into narrower rolls. Here’s how it works:

  1. Unwinding: The large roll of material is loaded onto the unwinding section of the slitting machine.
  2. Tensioning: The material is pulled through the machine at a controlled tension to ensure consistent cutting.
  3. Slitting: The material is passed through a set of sharp circular blades, called slitters, that are positioned at specific intervals to cut the material into narrower widths. The slitters can be adjusted to create different widths as required.
  4. Edge trimming: The edges of the material may be trimmed to ensure a clean, straight edge.
  5. Rewinding: The narrower rolls of material, called slit coils or webs, are wound onto separate cores using the rewinding section of the machine.
  6. Inspection: The finished slit coils or webs are inspected for quality and consistency before being packaged and shipped.

The slitting process is typically controlled by a high-precision programmable logic controller (PLC) that ensures precise cutting and consistent quality.

The type of slitting blade used can vary depending on the material being processed, with options including razor blades, crush cutters, or shear blades.

Overall, the slitting process is a critical step in converting large rolls of material into smaller, more manageable widths that can be used in a variety of manufacturing applications.
