| 1 | Punching devices | US194443 | 1988-05-16 | US4903560A | 1990-02-27 | Albert Halff; Manfred Vossen |
| A punching device for automatic punching machines for the punching of paper, cardboard and the like, comprising: a driving mechanism for a top shoe; such as a rocking lever drive, elliptical cam drive, or wedge-form transmission; a stationary bottom shoe supporting a counter-punch; a movable top shoe supporting punch knives; and a gripper bar arrangement for intermittent forwarding through the punching device of sheets to be punched wherein the drive mechanism for the top shoe is located between the top shoe and a yoke which is connected with the bottom shoe through prestressed tie rods. | ||||||
| 2 | Paper plate forming method and apparatus | US81263 | 1979-10-02 | US4242293A | 1980-12-30 | Daniel J. Dowd |
| Machinery for three dimensionally forming register cut paper articles such as plates, bowls and saucers is operated with a single, register controlled material supply web and a 2:1 cyclic speed differential between the blank cutting station and the hot forming press. Rotational drive speed of the machine is set and limited by the cycle rate of the hot forming press but two or more, register cut product units are cut and stacked from a single ply, registered controlled web supply within a single cycle interim of the forming press. Consequently, the speed limiting step of the entire machine continues, with a single ply web supply to operate with a high percentage of maximum productivity. | ||||||
| 3 | Paper cup bottoms and method and apparatus for forming same | US251355 | 1999-02-17 | US06135936A | 2000-10-24 | David C. Brown; Grigory Grishchenko; Anthony N. Curcio |
| A bottom for a paper cup is formed by advancing a punch against a paperboard web to push the web against a cutting edge which cuts out a circular cup bottom blank from the web. The punch is kept in a forward state to clamp an outer peripheral portion of the blank immovably against a surface of a sleeve. A reciprocable draw is advanced against a center portion of the blank to push the center portion into a circular opening of the sleeve while maintaining the clamping force, to cause the center portion of the blank to become stretched. The clamping force is then progressively released to permit the outer peripheral portion to enter the opening and become bent to form a lip extending at a substantially right angle. The lip is compressed within a gap formed between the draw and a surface of the opening. Because of the stretching of the blank, pleats formed in the lip are only in the form of micropleats that are flattened in a non-folded over state. | ||||||
| 4 | Method for forming an effective seal for a carton | US513359 | 1995-08-10 | US5667467A | 1997-09-16 | Joseph Christopher Walsh; Kenneth E. Hawkins |
| A method for providing paperboard to paperboard facing surfaces for forming an effective seal for cartons formed from a laminate of a relatively flexible fluid impervious material and a relatively rigid paperboard material. | ||||||
| 5 | Cut and score die apparatus and method | US475816 | 1990-02-06 | US5052992A | 1991-10-01 | L. Edward Hyder |
| A cut and score die apparatus is provided for progressively converting a sheet of material into blanks. The apparatus includes a punching section for punching scrap material from the sheet of material to define an array of interconnected blanks arranged in a grid of rows and columns on the sheet of material. A scoring section is provided for simultaneously scoring a first predetermined pattern on a trailing portion of a first row of blanks and a second predetermined pattern on the leading portion of a second, succeeding row of blanks on the sheet of material. A blanking section is also provided for piercing the sheet of material in a predetermined pattern to cut blanks from the sheet of material without producing any additional scrap material. | ||||||
| 6 | Apparatus for indexing and feeding a fitment web and related method | US165647 | 1988-03-08 | US4846915A | 1989-07-11 | Donald E. Keeler; Edward Bombolevich; Michael Sinocchi |
| An apparatus which coacts with a fitment application machine to index a die cut fitment web for precise registration and sealing of fitments to carton die cut areas. The apparatus includes an indexing wheel which has a plurality of circumferentially spaced indentations which engage void areas in the web defined by the fitments upon their removal. A gear and rack assembly intermittently rotate the indexing wheel advancing the web through the fitment application machine for sealing operations. Precise adjustment and indexing of the web is effected by a locating pin which engages corresponding bores in the indexing wheel to lock the wheel at defined pre-set circumferential positions. | ||||||
| 7 | Bottom blank maker workstation for a cup making machine | US306461 | 1994-09-15 | US5624367A | 1997-04-29 | Mark J. Budziszewski |
| A bottom blank maker workstation for a cup making machine is disclosed. The cup making machine is of the type having a rotating turret and a plurality of mandrels arranged to interact with a plurality of workstations. The turret moves each mandrel in a stepwise fashion through the plurality of workstations where a bottom blank and a sidewall blank are formed and attached to one another to create a container. The workstation includes a reciprocable punch and draw that cooperate with an abutment surface and a series of protrusions to impress the lip of the bottom blank with a series of indentations. The indentations promote a better seal to the sidewall blank. | ||||||

| 9 | Punching devices | US935408 | 1986-11-26 | US4763551A | 1988-08-16 | Albert Halff; Manfred Vossen |
| A punching device for automatic punching machines for the punching of paper, cardboard and the like, comprising: a driving mechanism for a top shoe; such as a rocking lever drive, elliptical cam drive, or wedge-form transmission; a stationary bottom shoe supporting a counter-punch; a movable top shoe supporting punch knives; and a gripper bar arrangement for intermittent forwarding through the punching device of sheets to be punched wherein the drive mechanism for the top shoe is located between the top shoe and a yoke which is connected with the bottom shoe through prestressed tie rods. | ||||||
| 10 | Punching devices | US322541 | 1981-11-18 | US4485708A | 1984-12-04 | Albert Halff; Manfred Vossen |
| A punching device for automatic punching machines for the punching of paper, cardboard and the like, comprising: impulsion means for a top shoe; such as an eccentric cam drive; a stationary bottom shoe supporting a counterpunch; a movable top shoe supporting punch knives; and a gripper bar arrangement for intermittent forwarding through the punching device of sheets to be punched wherein the impulsion means for the top shoe is located between the top shoe and a yoke which is connected with the bottom shoe through prestressed tie rods. | ||||||
