Title:
HEATING ROLL
Document Type and Number:
Japanese Patent JPS60159414
Kind Code:
A
Abstract:
A heatable roll has a plurality of annular, preferably electrical, heating elements (13) distributed internally along the length of the roll body (10,11). A slip-ring arrangement (22) rotating with the roll connects the heating elements with a heating current source (20) located outside the roll. A heating output setting device (9) arranged inside the roll is provided for each heating element and is connected to a signal transmitting arrangement (31 to 34). A control signal is formed for each heating element in a control center (21) located outside the roll, and is supplied to a parallel-serial converter (31). This converter forms one serial signal sequence from the plurality of parallel control signals, and this sequence is supplied, for example by means of slip-rings (22a), to a serial-parallel converter (34) located in the roll. This converter converts the serial signal sequence back again into parallel control signals which are supplied to the individual heating output setting devices.
