The teachings of the applied prior art
Van Haag
Van Haag's invention relates to an apparatus for treating sheet material with an
arrangement of rollers which has at least one roller gap through which the material is
passed with at least one heated roller. Figure 1 shows a diagrammatic view of an
apparatus 1 for processing a sheet 3 of material wound onto a roller 2. The apparatus
has a treatment station 5 including a calender 4. The calender 4 has two stacks 6, 7 of
rollers, each with three rollers. The central roller 8, 9 of each stack 6, 7 is constructed
as a heated roller. Each stack 6, 7 of rollers thus forms two heated roller gaps. A pipe,
the details of which are not shown, supplies a liquid heating agent to each heated roller
8, 9. The heating agent is discharged into a return pipe 10. The sheet material 3 is
passed through the calender 4 so that each side of the sheet comes into contact with a
heated roller 8, 9.
An unwinding station 11, in which the supplied rolled sheet material is unwound
in the direction of an arrow 12 from the roll 2, precedes treatment station 5. A roll
magazine 15, with several storage spaces 16, 17, 18 precedes the unwinding station
11. The last storage space 18 in the roll magazine 15, that is, the storage space
adjacent to the unwinding station 11, is surrounded by a housing 21. The housing 21
