| 摘要 |
The invention comprises a pair of cylinder (5, 6) between which the laminated product passes, with said cylinders (5, 6) applying pressure on this product, with at least one of said cylinders (5) comprising a nonstick coating, and characterized by the fact that said nonstick coating contains a polymerized fluoropolymer. This fluoropolymer is chosen from among perfluoroalkoxy (PFA), polytetrafluoroethylene (PTFE), ethylene tetra-fluoroethylene (ETFE), ethylene chlorotetrafluoroethylene (ETCFE), modified fluoroalkoxy (MFA) and fluorinated ethylene propylene (FEP). The coated surface adopts the typical characteristics of fluoropolymers: high surface energy (maximum non-stickiness), extremely low friction coefficient and resistance to corrosion and chemical attack.
