Abstract
Abstract The present roller press has a base, a center post, material supporting means, and roller means arranged in such a manner that the roller means or the material supporting means or both may be journaled about the center post whereby a relative movement between the material supporting means and the roller means is accomplished either by hand operation or by driving means, which movement follows a circular path around said center axis. The spacing between the supporting means and the roller means is adjustable to determine the cutting pressure and to accomodate material of different widths.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
155 words
A roller press for progressively cutting shapes out of relatively flat material by means of steel strip knives, comprising a base, a center post secured to said base and defining a center axis, means for supporting said flat material, main roller means, frame means for rotatably supporting said main roller means relative to said center post so that said main roller means provide a line of contact between a gEneratrix of said main roller means and said flat material, said generatrix extending radially and substantially perpendicularly toward said center axis, journal means journaled to said center post for permitting a relative movement between said material supporting means and said main roller means whereby said relative movement follows a circular path having its center located in said center axis, and two auxiliary, substantially cylindrical rollers supported by said frame means so that one auxiliary roller is arranged alongside of each side of said main roller means.
Claim 2
Dependent Claim
155 words
A roller press for progressively cutting shapes out of relatively flat material by means of steel strip knives, comprising a base, a center post secured to said base and defining a center axis, means for supporting said flat material, main roller means, frame means for rotatably supporting said main roller means relative to said center post so that said main roller means provide a line of contact between a gEneratrix of said main roller means and said flat material, said generatrix extending radially and substantially perpendicularly toward said center axis, journal means journaled to said center post for permitting a relative movement between said material supporting means and said main roller means whereby said relative movement follows a circular path having its center located in said center axis, and two auxiliary, substantially cylindrical rollers supported by said frame means so that one auxiliary roller is arranged alongside of each side of said main roller means.
Claim 3
Dependent Claim
33 words
The roller press according to claim 1, further comprising means for also rotatably supporting said auxiliary rollers in said frame means for movement along said circular path together with the main roller means.
Claim 4
Dependent Claim
63 words
The roller press according to claim 2, wherein said auxiliary rollers comprise longitudinal axes, and wherein said means for supporting the auxiliary rollers comprise guide slots in said frame means, said longitudinal axes of the auxiliary rollers having ends riding in said guide slots and resilient means pressing against the respective axis end whereby said auxiliary rollers are pressed downwardly and yield upwardly.
Claim 5
Dependent Claim
22 words
The roller press according to claim 1, wherein said auxiliary rollers extend with their longitudinal axis radially relative to said center axis.
Claim 6
Dependent Claim
25 words
The roller press according to claim 1, wherein each of said auxiliary rollers comprise a plurality of disks rotatably supported on a respective common axis.
Claim 7
Dependent Claim
37 words
The roller press according to claim 1, wherein said auxiliary rollers are spaced from said material supporting means to provide a spacing larger than the respective spacing between said main roller means and the material supporting means.
Claim 8
Dependent Claim
43 words
The roller press according to claim 1, further comprising power drive means operatively connected to said journal means and thus to said frame means for rotating the longitudinal axis of said main roller means and of said auxiliary rollers about said center post.
Claim 9
Dependent Claim
38 words
The roller press according to claim 1, wherein said main roller means comprise cylindrical roller means including a plurality of disks rotatably supported on common longitudinal cylinder axis means on which the disks rotate independently of each other.
Claim 10
Dependent Claim
58 words
The roller press according to claim 8, wherein the disks of each main cylinder roller are spaced from each other along their respective cylinder axis, said main cylinder rollers being arranged in such a manner relative to each other, that the disks on one roller register with spacings between the disks on the other roller and vice versa.
Claim 11
Dependent Claim
98 words
The roller press according to claim 1, wherein the base includes upright members, said material supporting means comprising flexible table means, means for stretching said flexible table means between said upright base members and for connecting the flexible table means to said upright base members, said journal means journaling said frame means to said center post in such a position that the main roller means are located below said flexible table means, abutment means and further journal means for journaling said abutment means to said center post whereby said abutment means are located above said flexible table means.
Claim 12
Dependent Claim
29 words
The roller press according to claim 10, wherein said frame means comprise guide roller means arranged to run on said base along a circular path around the center post.
Claim 13
Dependent Claim
34 words
The roller press according to claim 10, wherein said abutment means comprise a further roller means rotatably supported by said abutment means and having a rotational axis pointing substantially radially toward said center axis.
Claim 14
Dependent Claim
23 words
The roller press according to claim 12, wherein said further roller means comprise a conical roller pointing substantially radially toward said center axis.
Claim 15
Dependent Claim
