Applications

CD-N non-stop unwinder

The digital print process – from order intake to shipment of finished product – is highly digitized and automated. However, one costly and time-consuming factor disturbs this efficient chain: the need to change paper reels manually.

For printers who would like to optimize their workflow, shorten their delivery times, reduce labor costs and use their web inkjet press to the max, Contiweb non-stop winding equipment is the solution!

Fully automatic splicing of paper reels

The Contiweb CD-N unwinder works as a horizontal zero-speed compensator splicer, but with fully automatic splicing as well as integrated infeed as standard. The proven Contiweb zero-speed festoon design brings the running web and the new web to a halt during the splice cycle while the press is fed from the integrated festoon. Performing the splice at zero speed minimizes all dynamic forces on the web. The operation is therefore very forgiving of variations in splice preparation, such as operator skills and web quality. A lap splice is standard, and the CD-N can optionally perform one or two-sided butt splices.

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 regularly and repeatably 99.8% or higher.
  • You can splice over to papers of different web widths, coatings and weights.
  • If your press can accept it, Contiweb non-stop winding equipment sends a signal to your press when a splice is coming. This way the press can lift the print heads. The Contiweb equipment will even send a signal if it recognizes a splice made by the paper mill!
  • The lift arms of the Contiweb equipment can move up and down, allowing the reel to be loaded from the ground. This operation is ergonomic, and requires no lifting crane.
  • 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.
