Abstract
A heated roll with a circular cylindrical casing tube 1 made from thermally conductive metal, which is closed at its end faces with caps 2, 3. One or more electric heating mats 8 are arranged inside the casing tube 1. By at least one connection pin 5, which is arranged at one cap 2, connection cables 11 are guided for supplying the heating mats 8 with electric power. Annular brushing bodies 7 are fastened at the connection pin 5 and serve for the electric contacting of the connection cables 11. A tensioning device 9, 14, 15 is arranged inside the casing tube 1, which presses the heating mats 8 permanently against the interior surface of the casing tube 1.
Claims8
A heated roll comprising, a circular cylindrical casing tube (1) made from thermally conductive metal, caps (2, 3) which close axial end faces of the tube, one or more electric heating mats (8) arranged inside the casing tube (1), at least one connection pin (5) arranged on a first one of the caps (2) through which an connection cable (11) is guided to supply the heating mats (8) with electric power, an annular brushing body (7) fastened at the connection pin (5) forming an electric contact to the connection cables (11), and a tension device (9, 14, 15) arranged inside the casing tube (1), which permanently presses the heating mats (8) against an interior surface of the casing tube (1), and the tension device comprises at least two compression shells (9) formed as segments of cylindrical casings, which are connected to each other via adjustment members (15), and the adjustment members (15) move the at least two compression shells apart or towards each other.
