CR-N Non-Stop Rewinder

Contiweb’s CR-N non-stop rewinder can splice paper reels of different weight, web width or coating, without having to stop your press. Even varied finishing requirements can be accommodated as the Contiweb CR-N can roll up jobs onto different cores.

Non-stop winding equipment can help you to save considerable production and labor hours.

Automatic rewinding without production stop

The CR-N rewinder is fully automatic. The zero-speed operation ensures perfectly rewound reels without interrupting production. With the press in production, the running and new web are brought to a halt during the splice cycle, when the press is fed from the integrated festoon. The automatic splice can be made at production speed, at any reel diameter and at any time. Fully wound reels can be unloaded and cores prepared during production. A lap splice is standard, and the CR-N can optionally perform one or two-sided butt splices.

Shafts on the CR-N can be taken out and must be inserted into the core of the new reel. The arms can move the shaft up and down, so that reel loading and unloading can be done from the floor. No crane is necessary. The CR-N offers additional optional functionalities, including integrated electronic web tension control at outfeed, web guide, and slitter before the splice. With the integration of the slitter, printers can slit the web in ribbons with variable web widths before the splice, without interrupting production. While slitting, it is possible to splice and switch from one reel to the next.

Benefits

  • Non-stop winding saves considerable production and labor hours.
  • Change reels and prepare splices during production, so avoiding production stops.
  • Preparing the splice is very easy and takes only two minutes. The splice performance is 99.8% or higher.
  • You can splice over to papers of different web widths, coatings and weights.
  • The non-stop rewinder allows you to make a splice whenever you want, without stopping production.
  • The lift arms of the Contiweb equipment can move up and down, allowing the reel to be loaded from the ground.
  • Additional advantages are: fewer mistakes when preparing the splice, less chance of losing the web completely out of the engines (time pressure of production). Less waste by cutting unnecessary white paper, fewer startup problems, energy savings by quick change over.
