Patent number: 5881623Abstract: There is disclosed a construction in which the shaking of a cutting carriage due to a clearance is prevented, thereby enhancing cutting precision. The cutting carriage includes at least one rotary blade for cutting a sheet, and a pair of opposed driven rotary members held respectively against obverse and reverse surfaces of a guide track member, said pair of driven rotary members being rotated in accordance with the movement of the cutting carriage along said guide track member. The cutting carriage for sheet cutting can include a pair of rotary blades which are forcibly rotated respectively by the pair of driven rotary members when these driven rotary members are rotated. Preferably, the pair of rotary blades are held in press-contact with each other at a toe-in angle.Type: GrantFiled: February 7, 1997Date of Patent: March 16, 1999Assignees: Hitachi Metals, Ltd., HMY, Ltd.Inventors: Hitoshi Otani, Junichi Nakao

Patent number: 5868056Abstract: An actuator apparatus (10) includes a transverse support structure (14) for guiding a transverse carriage (16) therealong, with the carriage being powered by a remotely located rotational actuator (20) through an endless belt (80) secured to the carriage (16). A second carriage (26) moves along a longitudinal support structure (24) cantilevered transversely from carriage (16). The second carriage is powered by a remotely located second rotational actuator (28) acting through a second endless belt (150). A working tool (30) is mounted on the second carriage (26) for high speed bi-directional movement.Type: GrantFiled: January 17, 1997Date of Patent: February 9, 1999Assignee: Design Systems, Inc.Inventors: Craig E. Pfarr, Michael J. Wierman

Patent number: 5603253Abstract: A method and apparatus are provided for cutting a decorative groove in a matboard. The matboard is positioned adjacent a guide. A carrier is adapted to be moved along the guide with two blades oriented in separate planes which intersect each other and which lie at an oblique angle relative to the matboard. One of the blades is inserted into the matboard at a selected first depth. The carrier is moved along the guide for a predetermined length of travel to make a first cut in the matboard defining a first side of the groove. The blade is then retracted. Then the other blade is next inserted into the matboard to a selected depth at least intersecting the first cut. The carrier is then moved back to the initial location to make a second cut in the matboard defining a second side of the groove. In a preferred embodiment, the tips of the blades are offset from each other relative to the length of the groove.Type: GrantFiled: February 4, 1994Date of Patent: February 18, 1997Inventor: Malcolm Logan

Patent number: 5601007Abstract: An apparatus for forming a tab portion on a thin laminated sheet having work stations for scoring the sheet on a forward edge along a line to form the tab portion. The tabbing station includes a shuttle member having a pair of spaced rollers, one with a cutting edge and the other being a backing roller. The edge to be scored is passed between the rollers, such that the cutting roller as it traverses the length scores the sheet by a controlled amount which is determined by the preselected spacing between the cutting edge and the backing roller, whereby the unscored portion remains the same thickness regardless of the thickness variations of the sheet.Type: GrantFiled: November 22, 1994Date of Patent: February 11, 1997Assignee: Polaroid CorporationInventors: Arthur H. Clough, Matthew D. Guzzetta

Patent number: 5537904Abstract: A reversible mat cutter for cutting openings in oversized picture frame mats is disclosed. In one aspect of the invention, the guide rod and mat bar are easily detachable from the clamping frame of the mat cutter. Once detached, the cutter head assembly is then easily removed, reversed and remounted on the guide rod such that the cutter head then cuts on the opposite side of the guide rod. Both the mat guide and squaring arm are both quickly and easily detached from one side of the guide bar and remountable on the other side so that then an oversized picture mat may then be lain flat on the mat cutter and cut with the reversed cutter head.Type: GrantFiled: August 11, 1994Date of Patent: July 23, 1996Inventor: Stephen D. Albin

Patent number: 5503053Abstract: A sheet material cutting mechanism for cutting sheet materials two rotary blades and a mechanism for pressing down a sheet material to be cut. When the motor is started, a screw shaft 2 rotates, and a rotary blade assembly 4 starts to move to the right in FIG. 1 . Then, the roller 12 rotates by friction with a frame 1, and a first rotary blade 10 rotates by the rotation of a roller. At the same time, a second rotary blade 20 also rotates by the frictional force generated between the rubber roller 22 and the frame 1. The sheet material, fed into the sheet material receiving portion 17, is pressed by the rubber roller 22 against the surface 5 of the frame 1 immediately before cutting to prevent lifting or bending of the sheet material, thereby producing satisfactory cutting of the sheet material.Type: GrantFiled: October 12, 1994Date of Patent: April 2, 1996Assignee: Onishilite Industry Co., Ltd.Inventors: Takamasa Onishi, Zentaro Kamura, Hideo Yamato

Patent number: 5442983Abstract: An all-electric web feeding, cutting and sheet dispensing machine includes a bi-directional cutting knife on a reversible carriage driven by a reversible-rotation knife-drive shaft. The carriage includes a ball-bearing-wheeled linear actuator riding on the knife-drive shaft propelling the carriage along this shaft in cutting strokes in one or the other direction as this shaft is rotated in one or the other sense of rotation for cutting sheets off from a web of resilient packaging material. A combined knife-guard and clamp jaw (guard/clamp) holds the web and protects the moving knife from contact with foreign objects while the knife is traveling during each cutting stroke. At the end of each cutting stroke a cam on the knife carriage lifts the guard/clamp in readiness for feeding another length of web.Type: GrantFiled: September 30, 1993Date of Patent: August 22, 1995Inventors: Joseph J.
