Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
A track supporting roller guide for casting tracks produced by means of a liquid-cooled mold in casting systems, particularly curved casting systems, in which rotatable and mutually changeable supporting rollers for the track are arranged on two equidistant curves, a frame means, a link chain one end of which is located adjacent the liquid-cooled mold, means attaching only those rollers located on one side of the track to the link chain, means attaching the rollers on the other side of the track to the frame means, joint bolts connecting the links of the chain and a support at the frame means capable of being preset for supporting each of the joint bolts.
Claim 2
Dependent Claim
112 words
