ABSTRACT:
The disclosure concerns a hollow rotatable cylinder which is particularly useful as the drying cylinder for a paper machine. A circumferentially spaced apart array of sets, each comprised of at least a pair of axially arrayed cleats, are positioned around the inner cylindrical wall of the cylinder. Each cleat is comprised of a strip of sheet metal folded over a bar in direct engagement with the cylinder wall. Axial end pins on the cleats extend radially outwardly into boreholes provided in the inner cylinder wall. The end pins are dimensioned so that adjacent end pins of axially adjacent cleats may be received in a common borehole. In addition, a resilient holding ring may outwardly bias the cleats toward the inner cylinder wall. Finally, the cleats may be magnetically attracted to the inner cylinder wall for being held there.
