Roller press
A portable roller press can be configured with a suction base to stabilize the press during operation. The suction base can allow for the roller press to remain stationary when feeding cutting or embossing dies or templates through the rollers. Substantially the entire bottom surface of the roller press can correspond to the suction base. The suction base can be configured to be generally rectangular or generally oval or circular. The spacing between the roller can be maintained to a desired tolerance that is based on a working height of corresponding cutting or embossing dies or templates. A crankshaft distinct from a roller shaft can be used to transfer rotational forces to the rollers.

This application claims the benefit of U.S. Provisional Application No. 60/570,165, filed May 11, 2004, entitled ROLLER PRESS; which is hereby incorporated herein by reference in its entirety.
FIELD OF THE DISCLOSUREA roller press and, more particularly, a roller press with means to stabilize the roller press to a substantially flat surface.
BACKGROUND OF THE DISCLOSUREDies and sheet cutting presses are used to cut various patterns out of sheet materials. The presses are designed to apply uniform pressure to a die through a series of rollers to cut through a sheet or a plurality of sheets simultaneously. The resulting shapes are a result of the die that is inserted into the rollers in the roller press which applies pressure to the die and the material to be cut from.
BRIEF SUMMARY OF THE DISCLOSUREA portable roller press can be configured with a suction base to stabilize the press during operation. The suction base can allow for the roller press to remain stationary when feeding cutting or embossing dies or templates through the rollers. Substantially the entire bottom surface of the roller press can correspond to the suction base. The suction base can be configured to be generally rectangular or generally oval or circular. The spacing between the roller can be maintained to a desired tolerance that is based on a working height of corresponding cutting or embossing dies or templates. A crankshaft distinct from an axis of any the rollers can be used to transfer rotational forces to the rollers. A pinion gear on an end of the crankshaft can be used to drive a drive gear positioned on one end of a roller shaft. The ratio of teeth on the drive gear relative to the pinion gear can be designed to reduce the rotational force needed to feed the cutting or embossing dies or templates through the rollers.
An embodiment of the disclosure includes a roller press including a frame, a crankshaft supported by the frame and configured to receive a first rotational force, a first roller supported by the frame and having a first roller shaft coupled to the crankshaft and configured to rotate based on a rotation of the crankshaft, a second roller supported by the frame and having a second roller shaft coupled to the first roller shaft and configured to rotate synchronized to the rotation of the first roller, and a suction base coupled to the frame and configured to stabilize the roller press by applying a partial vacuum on at least a portion of the suction base.
An embodiment of the disclosure includes a roller press including a frame, a crankshaft supported by the frame and configured to receive a first rotational force, a pinion gear positioned near a first end of the crankshaft, a first roller supported by the frame and having a first roller shaft, a drive gear positioned on the first roller shaft and coupled pinion gear to rotate the first roller shaft based on a rotation of the crankshaft, a first roller gear positioned on the first roller shaft, a second roller supported by the frame and having a second roller shaft, a second roller gear positioned on the second roller shaft and coupled to the first roller gear and configured to rotate synchronized to the rotation of the first roller, and a suction base coupled to the frame and configured to stabilize the roller press by applying a partial vacuum on at least a portion of the suction base.
An embodiment of the disclosure includes a method of rolling material in a roller press, including stabilizing a roller press to a surface using a partial vacuum, rotating a crankshaft of the roller press, and supplying a working material to a working area of the roller press.
An embodiment of the disclosure includes a method of manufacturing a roller press, including locating the crankshaft in the frame, locating the first roller in the frame so as to couple the first roller shaft to the crankshaft, locating the second roller in the so as to couple the second roller shaft to the first roller shaft, and coupling the frame to the suction base.

DETAILED DESCRIPTION OF THE DISCLOSURE
As also shown in
As shown in
As shown in
For example, the distance between the rollers 25 and 27 can be maintained to within a tolerance of less than approximately 0.010 inch when using a cutting die that uses a chemical etched die. The total distance between the outside diameters of the top roller 25 and bottom roller 27 can be maintained to approximately 0.317±0.005 inch when an associated cutting assembly has a working height of approximately 0.325 inch, not including the material being worked. This can correspond to a distance of approximately 0.907 inches between the rotating axis of the top roller 25 and the rotating axis of the bottom roller 27.
Although the disclosure has been described by way of example and with reference to particular embodiments thereof it is to be appreciated that improvements or modifications may be made thereto without departing from the scope and spirit of the disclosure as set out in the claims.
