Device for copper plating rotating bodies having pivot pins, in particular gravure cylinders

摘要

The object of the device is to ensure an optimum method of operation for various rotating body dimensions, in which all the holes in the bath and seals in the liquid region which rub while rotating are eliminated. Two carriages (3a, 3b, 9) can be adjusted symmetrically with respect to the pivot pins of the rotating body (10) by axial spindles. Each pivot pin is gripped by a rotary carriage head (9) of a fixed lower section (3b) of the carriage. The current passes from the rotating body (10) through a current transmission device (16) which is provided with ring segments which slide over one another in a wedge-shaped manner and which is accommodated in the head (9) of the lower section (3b) of the carriage, and is fed into the upper section (3a) of the carriage through a non-rotating curved conductor (14a) which is surrounded by a bellows (8) which rotates with the carriage head (9). <IMAGE>
