Printing machine for printing on a three-dimensional article

摘要

A printing machine suitable for printing on a three-dimensional article of small size includes an inking arrangement having a roller such as a blanket roller for printing a pattern directly on the article, a pair of rails parallel to each other for supporting thereon the article, a pair of guides extending above the rails for guiding the article therealong, a pushing member which is driven forward between the rails at the same speed as the peripheral surface speed of the blanket roller in synchronization with rotation of the blanket roller thereby forcing the article to slide forward on the rails to a printing position, and a controlling means for forcing an ink ductor into contact with a duct roller intermittently at fixed intervals. The printing machine further includes a mechanism for adjusting the position of the rails and the guides so that they correspond to the shape and the size of the article.
