Abstract: An arrangement for air cooling on drawing die drums, by which the drawing die drum, covered by a protective screen, with one end of the drum under formation of an air exit - annular gap is immersed in an annular chamber, the latter being connected with a source of cooling air. A tube section bridges across the space between the air exit - annular gap and the protective screen.

Abstract: An inner cooling system on drawing die drums, particularly for the working of wires, includes an inner insert extending substantially across the width of the drawing die drum and slightly spaced from the inner jacket wall of the drawing die drum defining a small rotational gap therebetween, the inner insert being stationarily mounted relative to the rotating drawing die drum. A cooling medium - feed conduit is flow-wise in communication with the gap. The inner insert includes axially extending ribs dividing the inner insert into a plurality of individual chambers one behind the other in a peripheral direction, as well as additional ribs extending in the peripheral direction on an upper and lower edge, respectively, closing the individual chambers at the upper and lower edges, all of the ribs being directed on the inner jacket wall of the drawing die drum spaced therefrom by only the small rotational gap.
