Abstract
Abstract A rotary press for smoothing or embossing leather and like flat objects has a rotating pressure cylinder which cooperates with a concavely cylindrical trough on a stationary anvil. The object to be pressed passes through the trough between the cylinder and a laminar belt arrangement moving at the circumferential speed of the roller. The belt arrangement includes an abrasion resisting metal drive belt slidingly engaging the anvil, and a supporting belt of resilient material interposed between the drive belt and the pressed object.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A press for leather and like flat objects comprising, in combination: a. a support; b. a pressure cylinder having an axis and mounted on said support for rotation about said axis; c. anvil means fixedly mounted on said support and defining a trough of arcuate cross section transversely of said axis; d. belt means mounted on said support for translatory movement over said anvil in sliding engagement with said trough; e. pressure means for urging said cylinder under pressure toward said belt means and said trough; and f. drive means for rotating said cylinder about said axis and for simultaneously moving said belt means over said anvil at a speed substantially equal to the circumferential speed of said cylinder.
Claim 2
Dependent Claim
119 words
A press for leather and like flat objects comprising, in combination: a. a support; b. a pressure cylinder having an axis and mounted on said support for rotation about said axis; c. anvil means fixedly mounted on said support and defining a trough of arcuate cross section transversely of said axis; d. belt means mounted on said support for translatory movement over said anvil in sliding engagement with said trough; e. pressure means for urging said cylinder under pressure toward said belt means and said trough; and f. drive means for rotating said cylinder about said axis and for simultaneously moving said belt means over said anvil at a speed substantially equal to the circumferential speed of said cylinder.
Claim 3
Dependent Claim
159 words
A press for unfinished leather and like flat objects comprising, in combination: a. a support; b. a pressure cylinder having an axis and mounted on said support for rotation about said axis; c. anvil means fixedly mounted on said support and defining a trough of arcuate cross section transversely of said axis; d. belt means mounted on said support for translatory movement over said anvil in sliding engagement with said trough; said belt means including a belt member and a supporting belt member superimposed on said driving belt member, said driving member engaging said trough during the movement of said belt means, and said supporting belt member facing said cylinder; e. pressure means for urging said cylinder under pressure toward said belt means and said trough; and f. drive means for rotating said cylinder about said axis and for simultaneously moving said belt means over said anvil at a speed substantially equal to the circumferential speed of said cylinder.
Claim 4
Dependent Claim
159 words
A press for unfinished leather and like flat objects comprising, in combination: a. a support; b. a pressure cylinder having an axis and mounted on said support for rotation about said axis; c. anvil means fixedly mounted on said support and defining a trough of arcuate cross section transversely of said axis; d. belt means mounted on said support for translatory movement over said anvil in sliding engagement with said trough; said belt means including a belt member and a supporting belt member superimposed on said driving belt member, said driving member engaging said trough during the movement of said belt means, and said supporting belt member facing said cylinder; e. pressure means for urging said cylinder under pressure toward said belt means and said trough; and f. drive means for rotating said cylinder about said axis and for simultaneously moving said belt means over said anvil at a speed substantially equal to the circumferential speed of said cylinder.
Claim 5
Dependent Claim
67 words
A press as set forth in claim 2, said trough being of substantially cylindrically arcuate shape, said pressure means including means for moving said cylinder into a position in which the axis thereof substantially coincides with the axis of curvature of said trough, and said supporting belt member and said cylinder define therebetween a gap of substantially uniform thickness in a radial direction relative To said axis.
Claim 6
Dependent Claim
17 words
A press as set forth in claim 3, said belt members each extending in a continuous loop.
