Drum to smooth and/or cool a plastic web has a core separated from a mantle by laminated elastic layers alternating with metal bands

摘要

A rotating drum smoothes and/or cools a plastic web and has a powered drive shaft (1). The drum has a core (2) and a mantle (3) linked by a elastic intermediate layer (4). The elastic layer is made up of a series of laminations (4a, 4c), each separated from the adjacent layer by a metal band (4a). Two such drums form a nip gap.
