Product Description

Paper Machine Rewinder

Rewinder is a paper-making equipment, its use is the paper machine produced by the original paper rolls for sequential rewinding, paper after rewinding made into finished paper factory.

The rewinding machine is a special equipment for paper, mica tape and film. Its purpose is to rewind the paper roll produced by the paper machine (called the original paper roll), and the paper is re-rolled to make the finished paper. The AC drive of the factory rewinding machine has replaced the DC drive in the paper machine industry and has become a development trend.

The paper roll taken by the reel is relatively soft, the inside may be damaged or broken, the edges on both sides are not neat, the paper, the width of the sheet, etc. can not be directly used in paper processing or printing machines, most paper types (such as Newsprint, letterpress printing paper, wrapping paper, etc.) must be cut thqrough the rewinder, cut, joints, re-rolled on the paper core to form a certain specification, the finished paper roll with a certain tightness requirement can be shipped.

The Function of Rewinder

Rewinding process is mainly to complete three tasks:
First, remove the raw paper burrs.
Secondly, the whole sheet of raw paper cut into a number of widths in line with user specifications.
Third, control the roll diameter of the finished paper roll, so that it meets the factory specifications.

Braking method	DC motor braking/Variable frequency motor braking
Driving method	Electromagnetic variable-speed motor driving/variable frequency variable-speed motor driving

There have several spects need to notice:
Unwind section structure. The under reel (parent reel) diameter decide the unwind section structure and movement type. For the large-diameter and the large width reel, it should use the hydraulic pressure rather than manual way to control the parent reel movements.
Tension control of the unwind section. The old onfeed rewinder unwind tension cannot control automatically. During the reeling process, the operator always needs to adjust the web tension by operating brake pressure of unwind roll continuously. It is break easily during reeling, the paper forms and quality cannot meet the requirements.
