ABSTRACT:
A screen printing machine has a bearing supporting a first arm structure for rotation about a vertical axis, the first arm structure comprising first arms equiangularly distributed about the vertical axis and extending radially outwardly of the vertical axis. The first arms each carry, at a free outer end thereof, a printing screen support platen. A second arm structure has second arms equiangularly distributed about the vertical axis and extending radially outwardly of the vertical axis, the second arms each carrying, at a free outer end thereof, a squeegee mechanism and a printing screen support for holding printing screen below the squeegee mechanism. An indexing drive rotates the first arm structure stepwise around the vertical axis so as to position the platens in succession in registry with the squeegee mechanisms; and interengageable pairs of connectors are provided on the first and second arms for forcibly connecting the first arms to the second arms, to counteract bending of the arms during the operation of the squeegee mechanisms.
