How Does the Multifunction Slitting and Rewinding Machine Work?

1. Unwinding

The unwinding stage consists of an unwind stand onto which the parent roll of paper is loaded and secured.

The stand holds the roll about its central axis and allows it to rotate.

Our paper heavy-duty loading machine has clamping mechanisms to hold the jumbo paper roll into place.

2. Slitting

The slitter head is made up of a series of rotating round disc cutters or razors and it does the cutting of the web.

The desired slit widths are set manually or automatically depending on the type of machine being used by varying the locations of the knives on the slitter head.

The round disc cutters can be either rotating discs or static.

The type of pneumatic cutters depends on your specifications. The series of round disk  cut the web of paper into desirable sizes.

The cutting method is shear cutting. A bottom-placed round disc cutters work with an upper round disc cutter. They work in tandem and produce a scissor-like cut. It produces very clean cuts of very high quality.

It is important that you ensure that the round disc cutters are always well set and aligned. This is to avoid having uneven cuts. Blunt round disc cutters will also lead to uneven edges.

3. Rewinding

The slits are rewound onto smaller cores on the rewind stand to the desired footage or diameter.

This occurs from the slitter head. Various factors determine the type of winder to be used under a given condition.

The rollers which are after the slitter head keep the slit sections separate. This is as they enter the winding and prevent the sheet from weaving back and forth. This occurs between adjacent rolls in the roll set.

The heavy-duty unloading machine is equipped with an automatic hydraulic jumbo roll loading rack. The loading capacity is up to 3 tons.

The edge position controller installed on the heavy-duty machine helps guide the web material to the slitting part neatly.
