  • FIG. 6 is a side view of a portion of the apparatus shown in FIG. 1 illustrating a take-off device
  • FIG. 7 is a top view of the take-off device shown in FIG. 6.
  • FIGS. 1 and 2 an automatic cup printing machine is shown having a base 1 and a cup feeding device 2.
  • the printing machine is made up of a transfer device A, a vertical printing mechanism B, and over-varnishing apparatus C, and a take-off device D.
  • the transfer device A consists of a rotating turntable 3 having eight angularly spaced radially extending spindles 4 with cup holders 5 located on their radially outer ends. Additionally, the transfer device contains a vacuum and air blast control device, not shown, which is incorporated into the support for the rotating turntable 3.
  • the transfer device A rotates so that the cup holders 5 are sequentially positioned before the vertical printing mechanism B.
  • the printing mechanism consists of a printing cylinder 6 supported on two sides with six block cylinders 7 in contact with the surface of the cylinder spaced from the transfer device, and six inking devices 8 each cooperating with one of the block cylinders.
  • a hand wheel 9 Positioned in the base 1 below the printing mechanism is a hand wheel 9 for effecting the longitudinal adjustment of the printing mechanism and another band wheel 10 is also positioned on the base for effecting the oblique adjustment of the printing mechanism. Further, the entire printing apparatus is secured on a vertically adjustable plate which is located on the base 1.
  • cup 17 is shown mounted on one of the cup holvders'S in contact with the over-varnishing apparatus.
  • the over-varnishing apparatus includes an applicator roller VII in contact with the cup 17 on the holder 5, a-
  • ductor roller 12 contacting the applicator roller and a squeezing roller 13 in contact with the ductor roller.
  • a varnish passage with overflow is formed between the ductor roller 12 and the squeezing roller 13.
  • the rollers 11, 12 and 13 are driven in synchronism with the printing machine and with the spindle drive 14.
  • the application of varnish on the cups 17 is determined by the change wheels and l6.
  • an additional motor 18 is provided which affords a synchronous drive in a freewheeling manner for the varnishing rollers so that the varnish does not dry on the rollers.
  • the over-varnishing apparatus C can be used both in a horizontal plane and in an inclined plane, such win the 45.plane described above and for effecting the angular adjustment of the over-vamishing apparatus it can be displaced about a pivot bearing 19 by releasing a lock 20 on a pneumatic cylinder 21 incorporated as a part of the apparatus.
  • the varnishing apparatus is stopped in the event a cup 17 is not located on the cup holder 5.
  • 'A gear wheel 22 is in operative engagement with the ductor cylinder 12 and another gear wheel 23 is in operative connection with the applicator roller 1 l and the gear wheels are arranged for adapting the circumferential velocity of the applicator roller to the ductor roller.
  • a carriage 24 supports the overvarnishing apparatus C and is mounted on a pair of guide bars 25 so that the apparatus can be adjusted to accommodate the diameter variations of the cups being printed.
  • the conical arrangements of the applicator roller 11 isadjustable, by means of the pivot bearing 26, to the ductor roller 12. Due to its'arrangement and adjustable features, the over-vamishing'apparatus can be used to varnish both conical and cylindrical cups.
