Machine for the multi-colour silk-screen printing of containers with curved surfaces

摘要

A multi-colour silk-screen printing machine for containers with curved surfaces comprises a loading station (6) for the containers (7) to be silk-screen printed, a series of printing stations (8) and a discharge station (9) for the silk-screen printed containers, in which said printing stations are equidistant along a circular path tangential to which the screens (18) are positioned, and along which a number, equal to the number of printing stations, of radial mandrels (5) supporting the containers in a horizontal position are rotated stepwise, for each mandrel (5) there being provided two endpieces (30) arranged symmetrical about the longitudinal axis (55) of this latter; two printing stations (8) for each component colour of the multi-colour silk-screen printing; a drive member (25) for rotating the mandrel through 180 DEG during its transfer from one station to the next; and a transmission linkage which connects together the two endpieces of each mandrel and which during the printing of one container arranges the opposing container in the correct starting position. <IMAGE>
