| 241 | Process for preparing stamp | US888189 | 1997-07-03 | US5878668A | 1999-03-09 | Yoichi Ando; Hajime Toda; Koichi Hirano; Hisami Tamano |
| On the surface of an ink-permeable sponge material having open cells, a melted portion and an unmelted portion are formed by a thermal head printer controlled by a memory processor for desired imprint data to prepare a stamp having the unmelted portion as an ink oozing imprint surface. Furthermore, a stamp material plate comprising the tape-like sponge material is wound up in the form of a roll and then received in a cassette case, and a stamp material cartridge comprising this cassette case is mounted in a cartridge receiving section of the thermal printer capable of printing in a tape form. A print image set by input from a keyboard or external input is printed on the stamp material comprising the sponge material fed from the cartridge by the thermal head, while the stamp material is pressed, to form a concave having a depth of 0.01 mm or more, thereby preparing a print plate for a stamp having a suitable length.A process for preparing a stamp of the present invention comprises simple steps, and therefore the high-quality stamp can be promptly provided. | ||||||
| 242 | Method of producing a planar stamp | US3001 | 1998-01-05 | US5845573A | 1998-12-08 | Hiroyasu Miyata |
| A method of producing a planar stamp including a stamp member, an ink reservoir, and a stamp frame. In the method, after fitting the ink reservoir into the stamp frame, the stamp member, without a print surface and made of a polyethylene foam sheet, is adhered to the stamp frame in order to enclose it in the stamp frame, whereby a planar stamp portion is assembled. Then, a thermal head of a print surface forming apparatus is moved along an entire surface of the stamp member, while the thermal head is in contact with the stamp member, in order to form a print surface. Lastly, ink is injected into the ink reservoir in order to impregnate the stamp member with the ink. | ||||||

| 244 | Apparatus for cutting printing plates | US349566 | 1982-02-17 | US4452598A | 1984-06-05 | Charles R. Marsh |
| Apparatus for cutting printing plates, comprises a cutting press with relatively movable platens one of which carries a form cutting tool for severing or partially severing from a processed sheet of flexible material a central image-bearing portion for use as a printing plate. Retractable registration and holding means engage registration targets on said sheet so as to locate the sheet in registry with the form cutting tool and to hold the sheet in position at least until it is held by the pressure of the cutting tool thereon. | ||||||

| 247 | Method for molding a curved flexible printing plate | US652836 | 1976-01-27 | US4136150A | 1979-01-23 | John C. Darnall, Jr. |
| A flexible printing plate is separated from the inner surface of a curved matrix after formation of the plate in a mold by first moving the ends of the plate inwardly away from the matrix, while maintaining the center of the plate in stationary contact with the matrix, and then moving the center of the plate inwardly away from the matrix, while maintaining the ends of the plate away from the matrix. The matrix is held in an outer mold half, and the printing plate is formed in a mating inner mold half having a center section with sloping side surfaces that converge toward the outer mold half, a first end section having a side surface contiguous to one sloping side surface of the center section, and a second end section having a side surface contiguous to the other sloping side surface of the center section. | ||||||
| 248 | Apparatus for molding characters on a blank | US340174 | 1973-03-12 | US4011035A | 1977-03-08 | Russell L. Root |
| An improved apparatus and method is provided for molding a plurality of plastic characters on the upper surface of a plastic blank having a passage at each location where a character is to be molded. Rotatable die wheels having character defining recesses or cavities are disposed at a molding station above a support for the blank. These die wheels are rotated relative to each other to align cavities defining selected characters directly above the passages in the blank. The aligned die wheels are then moved into abutting engagement with the upper surface of the blank with the passages in the blank communicating with the cavities of the wheels which define the selected characters. Plastic material is then forced through the passages in the blank and into the cavities to simultaneously mold the selected characters on the upper surface of the blank. | ||||||
| 249 | Molding a plastic printing plaque | US3695807D | 1970-08-17 | US3695807A | 1972-10-03 | SORENSEN ROBERT L; CASANOVA JOHN |
| A flat, generally rectangular plastic printing plaque is made in a mold formed with a shallow, generally rectangular cavity for receiving and molding a plastic substance. The mold has a flexible portion and is movable between open and closed positions. A press encloses the mold and holds it closed under pressure to facilitate molding of the plastic substance. The relative conformation of the mold and press is such as to leave an insulating space between the flexible portion and the press. The mold is overcharged so that there is a total lateral deformation of the flexible portion which is within the range of 0.002 inches to 0.020 inches and preferably within the range of 0.006 inches to 0.010 inches.

| 250 | Printing plates in registry | US3677121D | 1970-10-13 | US3677121A | 1972-07-18 | ETCHELL GORDON |
| A machine for trimming flexible letter press printing plates to final size and simultaneously punching mounting appertures therein in accurate register with the plate image. The illustrated machine includes a vertically moveable die head and a die base plate with structure for supporting an untrimmed flexible printing plate in a predetermined position on the base plate. The die base plate is laterally moveable from an outwardly extended position to a determined position directly below the die head. When the die base plate is in proper position beneath the die head, selectively operable hydraulic actuating elements may lower the die head, into contact with the die base plate to trim and punch the flexible plate in finished form.

| IN PREPARING A COPPER FACE PLATE OF PRECISE LENGTH AND WIDTH FOR USE IN PRODUCING AN ELECTROTYPE PRINTING PLATE, A COPPER SHELL OF GREATER LENGTH AND WIDTH IS ELECTROLYTICALLY DEPOSITED UPON A MOLDED PLASTIC IMPRESSION OF THE PATTERN FACE OF THE ORIGINAL OR STARTING FORM (I.E. THE TYPEFORM, CONTAINING A POSITIVE PATTERN OF THE SUBJECT MATTER TO BE PRINTED, AND THE ADJACENT FRONT FACE OF THE ORIGINAL MOLD FRAME, WHICH ENCIRCLES THE TYPE-FORM). IN THE PREFERRED EMBODIMENT OF THE INVENTION, THE FRONT FACE OF MY MOLD FRAME IS PROVIDED WITH AN ENDLESS GROOVE WHICH ALSO ENCIRCLES THE TYPE-FORM AND WHICH IS MORE OR LESS CENTERED ON A "BOUNDARY" PATH ACCURATELY REPRODUCING SAID PRECISE LENGTH AND WIDTH BOUNDARIES OF THE COPPER FACE PLATE. THIS ENDLESS GROOVE IS CROSS-SECTIONALLY CONTOURED TO FORM A PAIR OF NARROW VALLEYS SEPARATED BY A SHARP RIDGE, WHICH IS PRECISELY LOCATED ALONG SAID BOUNDARY PATH TO REPRODUCE SAID BOUNDARIES ACCURATELY. ACCORDINGLY, WHEN A NEGATIVE PLASTIC IMPRESSION IS TAKEN OVER THE PATTERN FACE OF THE STARTING FORM, THE ENDLESS GROOVE CAUSES A CORRESPONDING PROJECTION TO BE FORMED ON THE IMPRESSION WHILE THE SHARP RIDGE IN THAT GROOVE CAUSES A STEEP VALLEY
TO BE FORMED IN THAT PROJECTION. NOW, WHEN THE PLASTIC IMPRESSION IS CONDUCTIVELY COATED AND ELECTROPLATED, THE THICKNESS OF THE COPPER "SHELL" WILL INHERENTLY BE REDUCED ALONG THAT DEEP VALLEY AND THAT THICKNESS REDUCTION WILL CENTER SHARPLY ON THE BOTTOM OF THAT VALLEY. AS A RESULT, DURING THE STRIPPING OPERATION, WHEN THE PLASTIC SHEET AND SHELL ARE SEPARATED FROM EACH OTHER, THE EXCESS MARGIN AND THE COPPER FACE PLATE PORTIONS OF THE SHELL CAN BE CONTEMPORANEOUSLY SEPARATED FROM EACH OTHER BY TEARING THE SHELL ALONG THE CENTER OF THE LINE OF REDUCED THICKNESS. AS A CONSEQUENCE, SAID COPPER FACE PLATE WILL HAVE THE PRECISE LENGTH AND WIDTH DESIRED. THIS ELIMINATES THE NORMALLY REQUISITE OPERATIONS OF SEPARATELY TRIMMING EACH MARGIN OF THE COPPER SHELL. |
