Slitter Rewinder for PAPER

It slits master roll into any desired width rolls

Slitter rewinder

Normally, the original paper rolls from the paper mill are very big in size that we can not use them directly. Then the paper slitter rewinder is necessary to convert the large master rolls to needed size rolls.

Hochint specially designed the most suitable model–the HFQA, HFQL, HFQD, and other models to fit the needs of our clients who want to get rolls of the correct width and diameter.

Our slitter rewinders are designed for a variety of paper, ranging from 20g-500g, as following:

  • kraft paper

  • silicon paper

  • coated paper

  • offset paper

  • art paper

  • paperboard

  • newsprint paper

  • parchment paper

  • release paper

  • insulation paper

  • copy paper

  • cup paper
