| 241 | Rotary die cylinder assembly | US928924 | 1986-11-07 | US4732083A | 1988-03-22 | James B. Arter; Thomas M. Serra |
| This rotary die cylinder assembly (10) is adapted for mounting annular members such as rotary knives (18) in locked relation thereon. The cylinder (12) includes a lengthwise extending slot (28) and a plurality of transverse bores (34) spaced lengthwise of the slot (28) and communicating with said slot. An elongate pressure bar (44) is received within said slot and set screws (46) are provided within said bores which are engageable with the pressure bar (44) to move said bar outwardly of said slot and into engagement with said annular member. Each member mounted on the cylinder is provided with arcuate slot (54) mating with the cylinder slot (28) and receiving the pressure bar (44) in accurately fitted locked relation when the set screws (46) are tightened. | ||||||
| 242 | Lateral perforation vertical registration device for offset press | US707251 | 1985-03-01 | US4598638A | 1986-07-08 | Yutaka Fujii; Takahiko Shinmoto |
| A lateral perforation vertical registration device for an offset press in which the position of lateral perforations formed on printing sheets can be accurately set without the need for running a number of test sheets. A lateral perforating position reading plate is provided made of a transparent material and having both lateral and vertical scales. A printing sheet is placed on the perforating position reading plate prior to printing to determine the position of lateral perforating. A vertical scale provided on the outer peripheral surface of a numbering device mounting cylinder is then adjusted relative to a fixed pointer to correspond to the value read on the reading plate. | ||||||
| 243 | Process and apparatus for perforating, stamping or creasing of paper and cardboard in rotary printing presses | US572672 | 1984-01-06 | US4596546A | 1986-06-24 | Rolf Schellenberg |
| In a rotary printing press with a blanket cylinder (2) and an impression cylinder (3), the blanket is removed and replaced by a base sheet (5). On this base sheet (5) are arranged strips (6). The arrangement of the strips (6) corresponds to the perforation, stamping or creasing to be produced in the paper or cardboard passing through the rotary printing press. On the impression cylinder (3) is arranged a smooth protective sheet (7). Both sheets (5) and (7) can be used several times and can be installed or removed rapidly by means present on the machine. | ||||||
| 244 | Automatically controlled numbering machine | US155143 | 1980-05-30 | US4306496A | 1981-12-22 | Jean Jacques Charbonneau; Christian Tailleux |
| A numbering assembly is disclosed, which is incorporated into a conventional press of the offset type and may selectively be rendered inoperative if numbering is not desired or printing is stopped, or automatically deactuated during the operation of the offset press if no printed material is discharged to avoid movement or change of numbers on the register in the absence of printed material on which a number is to be printed. The numbering assembly according to the invention comprises an improved control assembly including a first electrical circuit comprising a detection device responsive to the presence and absence of gripped material, a first normally open switch and a solenoid connected in series. The control assembly also includes a second electrical circuit which comprises a main switch, a relay connected to the first circuit in parallel to the solenoid, and the said solenoid, all connected in series. When actuated, the solenoid operates mechanical means which brings the numbering machine in operative position so that the number to be impressed be stepped each time a sheet of printed material is passing through the numbering machine. | ||||||
| 245 | Roll fed rotary web device with improved perforator | US687806 | 1976-05-19 | US4055101A | 1977-10-25 | Joseph Martin Collins |
| Disclosed is a roll fed rotary web device such as a rotary offset or rotogravure web printing press or a collator, having an improved perforator. Also disclosed are examples of prior art perforators. The perforator is incorporated in a standard perforating cylinder which rotates during the process of perforation. Perforating blades are mounted in the perforating cylinder and several improvements relating to spring biased positioners of the perforating blade are illustrated. | ||||||
| 246 | Removable redeemable coupon for newspaper advertisements and method and apparatus for producing same | US583621 | 1975-06-04 | US3995555A | 1976-12-07 | Frank E. Stewart |
| A removable redeemable coupon for newspaper advertisements and method and apparatus for producing same wherein the newspaper is printed in a rotary web press having a plurality of pairs of printing plate cylinders and blanket cylinders between which the web moves during the printing process. Printing plates secured in position on printing plate cylinders of certain pairs to print the faces of the web with news and advertisements including display advertisements with a redeemable coupon included therein. A plate having lines of perforating members is positioned on the printing plate cylinder of another pair to register with the boundries of the coupon printed on the web as said coupon passes thereby between the perforating plate and a cushion sheet adhered to the respective blanket cylinder of said another pair, said cushion sheet being larger than the area of the coupon whereby the cushion sheet retains the perforating members from contact with the blanket of the respective blanket cylinder and provides for the perforating plate to perforate the web with only normal impression adjustments, the perforating lines for a coupon being spaced from edges of the web and separation lines for pages. | ||||||
| 247 | Web printing means | US3713420D | 1971-01-21 | US3713420A | 1973-01-30 | PFAFFLE E |
| Means for printing margin lines on a web of ruled paper to be cut into multiple-leaved sheets, in which a trim allowance is to be provided at the ends of each sheet. The means comprises a margin line printing roll having a plurality of equidistantly spaced ridges. The roll is driven by a gear the teeth of which have a predetermined pitch, except for one section in which there is a larger pitch. The margin lines will be printed at even intervals during the time the roll is driven by the teeth of predetermined pitch, but with the paper moving at a constant speed, a slightly greater interval will occur between margin lines during the time the roll is driven by the tooth section of larger pitch. Thus, the web may later be cut to form sheets each of which has a trim allowance at the outer edges thereof. The sheet is later cut into individual leaves.

| 248 | Lining device | US3673937D | 1970-05-19 | US3673937A | 1972-07-04 | MADER PETER ERNST |
| A lining device comprising guide means and drive means which control the movement of a projection device in two coordinate directions over a photographic film. The projection device comprises a light source, an adjustable apertured diaphragm, and a lens which serves to direct light passing through the diaphragm onto the film in reduced size so that when the projection device is moved, a line is exposed on the film.

| 1,145,851. Bronze - printing machines. MOLINS MACHINE CO. Ltd. 24 March, 1966 [26 March, 1965], No. 12978/65. Heading B6C. A paper strip 1 has adhesive applied thereto in a design by a roller 6, and then passes under a guide roller 4 and between an electrode 10 and a roller 7 rotating in a powder reservoir 9. The roller 7 has a covering of emery cloth, whereby it carries powder to the vicinity of the strip. The electrode 10 is electrically charged under the control of a switching device synchronized with the roller 6 when a part of the strip having adhesive thereon passes below it, and produces an electrostatic field across the strip to a grounded electrode in the roller, so that the powder is attracted to the strip. The strip then passes over walls 18, 19 to a suction chamber 16, whereby and by means of a rotating brush 20, powder not adhering to the adhesive is removed. In another form, Fig. 3 (not shown), the strip passes over a charged grid (21) and between it and grounded electrodes (22, 23), whereby and by means of suction, the surplus powder is removed. In another form, Fig. 4 (not shown), baffles (24) are provided in the reservoir, the brush is accommodated between walls (25, 26) of the suction chamber, and further suction through an opening (28) assists in removing the powder. | ||||||
