What Is A Rewinding Machine Used For?

A rewinder,also known as a split coiling machine, is a simple device that "cuts large rolls into small pieces and rolls them upside down."
What exactly does it do?
Paper or coating machines usually produce master rolls that are very wide and several kilometres long, but downstream customers need finished rolls that are narrower in width and smaller in diameter. The rewinder is the key equipment to complete the conversion. The main actions are as follows:
First, longitudinal slitting. A large roll is cut into narrow strips along the width, for example, a 2-meter-wide roll into 10 20cm wide rolls.
Second, roll back horizontally. The narrow strips are rewound onto smaller cores to form individual rolls, which is the final finished products.
Third, trim the edges. Uneven or substandard edges are removed from both sides of the material to ensure the width of each strip is precise and consistent.
Four is automatic rewinding. A rewinder automatically cuts off a full roll, replaces it with a new core, and continues winding, greatly reducing downtime and efficiency.
Use it for what?
The paper industry most commonly uses toilet paper, napkins, photocopying paper, coated paper and laminated paper, all of which require a paper reel machine to convert large master rolls into smaller rolls for subsequent processing.
It is also widely used in the film industry, such as plastic, aluminum foil and PET films.
It is also in high demand in the The nonwoven fabric industry, such as medical nonwoven fabrics and civilian nonwoven fabrics.
In addition, the coiling machine can also be used in the processing of metal tape (copper tape, steel strips), tape and other products.
A rewinder is a processing device connecting the ``large volume at the end of production "and ``small volume at the end of user ''. Its core function is to slit, trim and curl into smaller rolls, turning large raw materials into small finished products that customers can use directly.
