ABSTRACT:
The invention is concerned with an apparatus for automatically attaching and detaching cassette-type rolls, which is suited for plating peripheral surfaces of the roll having shaft, and particularly for plating peripheral surfaces of a photogravure roll, with copper or chromium. The conventional apparatus which horizontally chucks both ends of a photogravure roll and which also spins the roll, could be adapted to the cassette-type hollow rolls, but could not be adapted to the cassette-type rolls having shaft. According to the apparatus for attaching and detaching cassette-type rolls of the present invention, the current-carrying supporters are exchanged depending upon the type of the roll to be treated, and the leak-proof caps are made up of moving caps that slide on the outer side of the spindles and exchange caps that are located between end surfaces of the roll and the moving caps. By suitably selecting and exchanging the current-carrying supporters and exchange caps, the apparatus can be adapted to different types of rolls having shaft. That is, the roll R with shaft is placed on the attaching/detaching plate, current-carrying supporters 4, 5 are fitted to the shaft portions, exchange caps 6b, 7b are fitted to the supporters 4,5, and the apparatus is placed on the roll to chuck it by spindles 2, 3. When the roll R with shaft of a different type is to be treated, another current-carrying supporters 4, 5 and exchange caps 6b, 7b are used, which are suited for it.
