  • Apparatus and method for the silk-screen printing of multiple curved peripheral surfaces of an article defined by multiple curved peripheral surfaces
    Patent number: 5419213
    Abstract: Silk-screen printing apparatus is provided for the silk-screen printing of articles such as oval-shaped bottles and containers on the two major curved peripheral surfaces thereof, sequentially, with one printing pass. The apparatus utilizes, in this case, two squeegees positioned one behind the other and synchronized in such a manner as to force ink through a screen provided with two image patterns as each of the two image patterns on the screen moves sequentially over the two curved surfaces to be printed.

  • Apparatus suitable for rapid silk-screen printing of plastic containers
    Patent number: 5142975
    Abstract: Apparatus for the transfer of ware in step-wise fashion from one point to another with silk-screen printing of the ware between the remote points. The articles of ware, in spaced-apart locations, are moved by an elongated horizontally disposed beam having a plurality of spaced-apart wareholders from a rearward horizontally disposed rest position downwardly in an arcuate path and then upwardly to a second forwardly located rest position in the same horizontal plane. The articles of ware are then each clamped while the beam reverses direction. A further article of ware is placed in the first wareholder, the other forwardly located articles being received in respective forwardly located wareholders. The beam then again moves forward and the articles of ware are each clamped. The beam then reverses direction, receiving a further article, etc. At the print station the articles are each raised vertically upwardly in a smooth curve, printed, and then lowered vertically downwardly in an opposing smooth curve.
