Abstract
Device (1) for manufacturing plastics films from a plastics melt and having a roll frame (3) in which at least one chill roll (2) is rotatably mounted, an exchangeable part of the device (1), for pressing the plastics melt against the chill roll (2) mounted in the roll frame (3) and for chilling the same, being attachable to the roll frame (3) and for the manufacture of plastics films with different characteristics, various modules (10) being provided as the exchangeable part, so that the device (1) allows different plastics films to be made by means of different manufacturing methods.
Claims16
A device for manufacturing plastics films with different characteristics from a plastics melt, comprising a roll frame, at least one chill roll rotatably mounted in the roll frame, exchangeable modules, for pressing the plastics melt against the chill roll for chilling the plastics melt, the exchangeable modules being individually and separately attachable to the roll frame, for the manufacture of plastics films with different characteristics, each of the exchangeable modules designed to manufacture plastics films with different characteristics by different manufacturing methods.
A device for manufacturing plastics films from a plastics melt and having a roll frame in which at least one chill roll is rotatably mounted, an exchangeable part of the device, for pressing the plastics melt against the chill roll mounted in the roll frame and for chilling the same, being attachable to the roll frame, characterized in that, for the manufacture of plastics films with different characteristics, various modules are provided as the exchangeable part, so that the device allows different plastics films to be made by means of different manufacturing methods, wherein the module for pressing and chilling the plastics film has a continuous band, optionally chilled, for surface-smoothing.
A device for manufacturing plastics films from a plastics melt and having a roll frame in which at least one chill roll is rotatably mounted, an exchangeable part of the device, for pressing the plastics melt against the chill roll mounted in the roll frame and for chilling the same, being attachable to the roll frame, characterized in that, for the manufacture of plastics films with different characteristics, various modules are provided as the exchangeable part, so that the device allows different plastics films to be made by means of different manufacturing methods, wherein the module for pressing and chilling the plastics film has an air knife.
