Continuous manufacturing process of flat elements with coating on at least two adjacent sides from a continuous starting band based on mineral wool

摘要

Continuous production of a panel, partic. a mineral wool insulation panel; covered or at least two adjacent faces from a continuous band consists of the following operations all carried out at the same line speed or the moving band: (a) Sticking the covering (2) on a first face of the band; (b) Maintaining the covering in position until the bonding is complete; (c) progressively folding the coating onto one or both sides of the band; (d) Sticking the coating on the sides; (e) Maintaining the coating in place until bonding is complete. The coating has an adhesive layer partic. polyethylene reactivatable to heat at least twice.
