Abstract
Abstract A mounting for supporting a pair of cylinders, particularly for use in printing machines, in which the cylinders are adjustably arranged and kept at a given distance from each other, wherein a first cylinder of the pair of cylinders is supported at each end thereof by a resiliently deformable member, and that the second cylinder of the pair of cylinders is movable towards, and away from, the first cylinder by means of an adjusting support device which, in operation, is responsive to resilient deformations of the resiliently deformable member when such deformations exceed a predetermined value.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
175 words
A mounting arrangement for rotatable cylinders comprising a support frame, at least two resiliently deformable beam members arranged opposite to each other and fixed to said frame, a first cylinder mounted for rotation in said resiliently deformable beam members, support means mounted in said frame for movement toward and away from said first cylinder, a second cylinder rotatably mounted in said support means parallel to said first cylinder and adapted to contact said first cylinder upon movement of said support means towards said first cylinder, reversible drive means for moving said support means and said second cylinder toward and away from said first cylinder, sensor means mounted on said frame and disposed in contact with said beam members for providing a signal responsive to the deformation of said beam members, and circuit means including said sensor means and said drive means responsive to the signal provided by said sensor means to stop said drive means when the pressure exerted by said second cylinder on said first cylinder causes a predetermined deformation of said beam members.
Claim 2
Dependent Claim
175 words
A mounting arrangement for rotatable cylinders comprising a support frame, at least two resiliently deformable beam members arranged opposite to each other and fixed to said frame, a first cylinder mounted for rotation in said resiliently deformable beam members, support means mounted in said frame for movement toward and away from said first cylinder, a second cylinder rotatably mounted in said support means parallel to said first cylinder and adapted to contact said first cylinder upon movement of said support means towards said first cylinder, reversible drive means for moving said support means and said second cylinder toward and away from said first cylinder, sensor means mounted on said frame and disposed in contact with said beam members for providing a signal responsive to the deformation of said beam members, and circuit means including said sensor means and said drive means responsive to the signal provided by said sensor means to stop said drive means when the pressure exerted by said second cylinder on said first cylinder causes a predetermined deformation of said beam members.
Claim 3
Dependent Claim
50 words
A mounting arrangement as set forth in claim 1, wherein said support means includes a pair of spaced apart slides displaceable in said frame and said drive means includes a nut and screw arrangement engagable with each slide and an electric motor operatively connected to each nut and screw arrangement.
