The holes which are not closed by the sheet are closed by a resilient layer 10 of rubber or resin which is pressed against the drum by an inner drum 9. The drum 1 is rotated by the guide roller 18. The sheet is cooled at 17. In modification, Fig. 3, the position of the inner drum 9<SP>1</SP> may be adjusted by an eccentric mounting 20, and suction may be applied through a hollow shaft 23 and holes 22.
