Roller coverings

Specialised in roller coverings, Hannecard has developed Flexolys-Foam, a compressible polyurethane covering quality that can be obtained in several density grades.

Flexolys-Foam assures an improved dynamic behaviour of rider, support and contact rollers and prevents nip-related stress defects during the high-speed winding of very thin and delicate substrates. The search for the reduction of vibrations during high-speed winding of BO-film has led the company (Italian HQ at Castelnuovo Scrivia, AL) to develop DuoStar-AS, a unique double-layer covering concept for contact rollers, composed of a soft and highly dampening base layer and a high abrasion resistant polyurethane outer layer.
