Retrofitting of a Clupak extensible unit.

BASALAN outsources to AUGI the electrical and automation parts of their retrofitting project to upgrade the existing Clupak extensible unit installed at their customer's paper mill Gascogne Paper in Mimizan, France.

The Clupak extensible unit is used in paper mills - specially in packaging, sacs, and labels - to control the tension energy absorption, achieve a longitudinal elongation of paper up to a 15%, and to eliminate breaks in the finished product.

The paper elongation is performed by compactation when passing the material between a rubber tapestry, the pressing bar and a drying cylinder heated with steam, independently of the various speeds of the actual extensible unit and the machine sections after that.
