- the cooling plate element 44 is, viewed in an operating state, below the cooling roller elements 46, 160, 162, 164, 166, 168, 170 arranged.
- the cooling device 40 only the cooling plate member 44 or has only the cooling roller elements 46, 160, 162, 164, 166, 168, 170 for cooling the material strand 14.
- the material strand 14 is conveyed by means of the conveyor belt 158 within the cooling device 40 across the cooling plate element 44. Subsequently, the material strand 14 is conveyed through the cooling roll elements 46, 160, 162, 164, 166, 168, 170. After the material strand 14 has traversed the cooling roller path of the cooling roller elements 46, 160, 162, 164, 166, 168, 170, the material strand becomes
- the strand of material 14 is cooled within the cooling device 40 to a temperature of about 0 ° C to 2 ° C. After the material strand 14 has left the cooling device 40, the material strand 14 together with the first carrier film 66 and the second carrier film 74 of a
- Foil Aufwicklungsvorraum 172 supplied.
- the film-winding device 172 is provided to separate the first carrier film 66 and the second carrier film 74 from the material strand 14 and to wind the first carrier film 66 and the second carrier film 74 separately from each other.
- the material strand 14 is then fed to a cutting device 174, which separates parts from the material strand 14, which are then further processed, for example by means of a press.
