Definitions

  • This invention relates to a priming unit for gold priming or the like for use in a platen press of the kind which prints the [58] Field of Search ..101/27, 287, 9, 10, 11, 336 required symbols onto a substrate fmm a foil in the form of a web which is unwound outside a type bed of the press and [56] Reerences cued rewound also outside the type bed.
  • the unit comprises a UNITED STATES PATENTS delivery roller for the foil, a winding roller on which the foil is rewound, a plurality of tension rollers which content the foil, 1,261,690 4/1918 Brool ce 101/27 and a plurality f d fl t f the f iL These are arranged on 2,035,957 3/ 1936 Gahnelsen -- ....101/27 areplaceable chase 2,424,725 7/1947 We1mont ..101/336 2,641,178 6/1953 Hendt et a].
  • a platen press comprising a type bed and means for advancing a gold foil from which symbols are to be printed, a printing unit comprising a replaceable chase for the type bed; a delivery roller outside the type bed from which roller the foil is unwound; a winding roller outside the type bed on which the foil is rewound after passing through the press; a plurality of tension rollers on the chase and applied to the foil; and a plurality of deflectors for the foil arranged on the chase.
  • FIG. 1 is a front elevational view of the unit in accordance with the present invention.
  • FIG. 2 is a side elevation of the unit shown in FIG. 1,- and FIG. 3 is an enlarged view of the freewheel mechanism for rotating the drive rollers.
  • a delivery roller 3 for a roll of foil 4 is pivotally mounted by means of a support 5 on an upper crossbar 2 of a chase 1.
  • the foil 4 travels downwards over the chase l to deflector plates 7 and 8 which are arranged on a lower crossbar 60f the chase and which deflect the foil through 180, and from there back to the upper end of the chase.
  • a heated type 9 is arranged inside the chase near the downwardly moving web of film 4. However, this type 9 may also be arranged near the upwardly returning web of foil, i.e., in FIG. 1 on the left-hand side of the chase.
  • a corresponding winding roller I0 for the printed foil web is mounted on a cylinder support 11 on the upper crossbar 2 of the chase.
  • Two tension or drive rollers 12 and 13 are also mounted on the cylinder support 11, on which the tension roller 12 is fixed, whilst the tension roller 13 is pivotally mounted on levers 14 to act as a counterpressure roller.
  • the levers 14 are arranged such that the support carrying the delivery roller 3 raises the roller 13 from the tension roller 12 when the delivery roller 3 is swung upwards out of the position shown in FIG. 2 for inserting new foil into the unit.
  • the printing unit is shown in its working position, i.e., the delivery roller 3 has been lowered and the tension roller 13 likewise lowered to rest on the tension roller 12 used to feed the foil, so that the foil web 4 guided between the two tension rollers is adapted to be pulled therebetween responsive to rotating movement of the tension roller 12.
  • the tension roller 12 rotates forwards in steps by way of a freewheel, the length of the steps being infinitely variable.
  • the tension roller 12 is mounted on a boss 15 the end of which projects laterally from the tension roller, to
  • the boss 15 is spring loaded by means of a spring 26 connected at one end to the boss and at its other end to the cylinder support 11, as shown in FIG. 2.
  • the pulling rope 16 leads via a guide roller 17 fixed to the cylinder support 1] to the free front end of a lever 18 provided with a slot and pivotally mounted on the chase.
  • the freewheel mechanism which is conventional and shown in FIG. 3, comprises an external ring 27 attached to the tension roller 12, and an internal disc 28 attached to the boss 15.
  • a plurality of notches commonly designated at 29 are formed in the disc 28 and receive therein a plurality of balls commonly designated at 30, the diameters of which are less than the length of the radial shoulder of the notches 29.
  • the movable platen moves the lever 18 toward the chase 1 until it is received in the plane thereof.
  • Such movement which is counterclockwise as viewed in FIG. 2 of the application drawing, carries with it the rope 16, which is operatively engaged to the top of the lever 18, extends around guide roller 17, and is attached at its opposite end as described to the spring-loaded boss 15.
  • Such movement serves to rotate the drive or tension roller 12 clockwise as viewed in FIG. 2, thereby driving or pulling the foil between the rollers 12 and 13 and onto the winding roller 10.
  • the winding roller 10 and tension or drive roller 12 are simultaneously driven through a belt or chain drive.
  • the freewheel mechanism described permits movement of the lever 18 in a clockwise direction, as viewed in FIG. 2, away from the chase 1 without rotative movement of the drive or tension roller 12.
  • the rope 16 is retracted by the spring-loaded boss 15 to condition the printing unit for subsequent advance of the foil by rotative movement of the tension roller.
  • a normally upright auxiliary lever 19 carrying a roller 20 at its free end is mounted on the lever 18.
  • the auxiliary lever 19 is pressed into the position shown in FIG. 2 by a spring (not shown). This spring is stronger than the spring loading of the boss 15 so that the auxiliary lever cannot be pushed into the slot in the lever 18 until this lever is in its depressed position, i.e., until the foil 4 stops moving forward. This ensures that the foil 4 is unable to make any movements during printing so that it cannot slip or tear.
  • the deflector plates 7 and 8 may be so mounted on the frame 1 as to be laterally displaceable. It is also possible to provide these plates with slots so that two or more sheets of foil can be passed simultaneously through the printing unit parallel to one another. Finally, it is also possible to replace the deflector plates with turning bars or the like.
  • the replaceable chase forms the frame by which the assembly as a whole is held together, so that the assembly is essentially a single unit.
  • the heated type may be fitted into the chase in the usual way.
  • Introduction of the chase into the platen press does not present any difficulties because the operation involved is a normal one to which any printer is well accustomed.
  • a printing unit for replaceably attaching between the platens of a platen press having two spaced platens one of which is movable into close proximity to the other platen to provide a printing stroke, said unit comprising a chase having an upper and lower crossbar interconnected by marginal side bars for holding printing members such as a type bed between said bars, said chase having mounted on said upper crossbar means for advancing a metallic foil from which symbols are to be printed by means of said printing members onto sheet or web material, a rotatably mounted delivery roller supported by said chase from which roller the foil is unwound, a rotatably mounted winding roller supported by said chase on which the foil is rewound after passing over said chase, said advancing means comprising a pair of drive rollers at least one of which is operatively connected to said winding roller, means on said chase operatively engaged by said movable platen only upon closing for driving said one drive roller for driving said winding roller to wind up said metallic foil, said drive rollers being provided with a freewheel and a springloaded

  • one of said drive rollers is provided with a freewheel and a spring-loaded boss connected through the freewheel to said one drive roller, a pulling rope drivingly connected at one end to the boss to be wound on or unwound from said boss, a guide roller contacting the pulling rope, and a first lever pivotally mounted on the chase and operably connected to the other end of said pulling rope, said first lever being normally raised with its free end from the plane of said chase by means of said spring-loaded boss and the pulling rope attached thereto, said first lever being adapted to be depressed by the movable platen of said platen press to rotate one of said drive rollers for stepwise advancing said foil over said chase.
