ABSTRACT:
An apparatus for applying markings to packed articles transported by a conveyor is provided with a stamp, which is laterally expulsed when an article passes by. The stamp comprises a holder and a printing head connected with the holder by at least one spring. The lateral movement of the holder is interrupted by an abutment in the driving mechanism before the printing head reaches the article, after which the printing head is shot out by the kinetic energy so as to hit the article. The printing head engages an ink pad in the intervals between successive printing operations. The ink pad is attached to the bottom of an ink container by means of a bearing ring and is made of a hard porous material. The printing head is provided with a resilient ring tightly engaging the edge of the bearing ring when the printing head lies against the ink pad. Thus, a suction occurs when the printing head leaves the ink pad, whereby the ink is drawn into the ink pad from the container.
