摘要： An improved apparatus for automatically printing two faces of an object. The present invention is an attachment for use with a screen printing press of the type shown in U.S. Pat. No. 3,090,300, issued to Louis Gilbert Dubuit on May 21, 1963. The attachment permits the utilization of two separate sections of the same screen to print the face and reverse side of an object of revolution, such as a bottle, and particularly bottles of oval or irregular shape. The attachment consists of a main drive train which rotates the bottle at the same surface speed as the movement of the screen. Means are provided to flip or invert the bottle 180.degree. during the return stroke with a separate means provided to shift the screen relative to the drive, presenting a different section of the screen to the reverse side of the bottle for printing when the machine cycles through its normal print stroke. As is customary in printing irregular objects, the squeegee is held stationary and the screen and object move at the same speed beneath the squeegee to print the impression in the screen on the work.
