Abstract:
A screen printing machine for multi-color printing on a web which is advanced horizontally on a supporting blanket includes parallel frame halves across which are mounted bridges. Each bridge has stencil holders for journaling the ends of cylindrical thin-walled screen stencils with there being one bridge for each stencil and the bridges extending parallel to the respective stencils. At least one end of a stencil is provided with a gear which meshes with a driving gear mounted in the frame half and protruding upwardly therefrom. The bridge is mounted on a frame half by means of a structure which permits adjustment of the bridge vertically longitudinally and transversely thereof so as to position accurately the stencil with respect to the advancing web.
