Abstract
Abstract A roll, for rolling metals or for grinding, comprises (1) a roll ring formed of a metal carbide, on (2) a metallic holder or support means, which latter means consists essentially in a flanged sleeve, on which the roll ring is disposed, with one side face of the same abutting against a peripheral part of the flange of the sleeve, and a co-operating flanged muff threaded onto the sleeve and having a peripheral part abutting against the other side face of the roll ring. Said flanges are so profiled as to leave annular slits on either side of the roll ring, in which slits there is provided a suitable adhesive substance ''''glueing'''' the roll ring to the flanges of the support means.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
140 words
Roll for rolling, grinding, crushing and the like which comprises a roll ring holder having two spaced flanges; a roll ring clamped between the two flanges on the roll ring holder, the roll ring and the flanges having matching contact surfaces shaped as surfaces of revolution directed transversely to the axis of rotation of the roll; means for clamping the roll ring between the flanges; at least one intermediate spacing member disposed between said congruent contact surfaces and forming between the latter a thin slit; and binder material in said slit, the roll ring being thus torsionally fixed between said flanges of the roll ring holder by the combined action of the clamping means and of the binder material, the torsional fixation being obtained exclusively by the clamping contact between the surfaces of revolution and the adhesion of the binder.
Claim 2
Dependent Claim
24 words
Roll as defined in claim 1, in which the holder device at the same time forms part of the roll shaft of the roll.
Claim 3
Dependent Claim
98 words
Roll as defined in claim 1, in which at least one of the flanges, between which the roll ring is mounted, has that annular surface thereof which faces the roll ring formed with a peripherically situated annular surface portion, which surface portion is somewhat raised in the axial direction over the annular surface portion that is situated closer to the center, so that the peripherically situated surface portion abuts against the roll ring, while the surface portion that is situated closer to the center is separated from the roll ring by a slit, which slit contains an adhesive.
Claim 4
Dependent Claim
17 words
Roll as defined in claim 1, in which the thickness of the glue joint is 0.01-0.25 mm.
