ABSTRACT:
A printing drum is rotatable supported by a fixed hollow cylindrical member at two axially spaced positions thereof so that the printing drum may be supported in a highly stable fashion and any mis-alignment of the printing drum can be avoided. Also, the interior of the fixed hollow cylindrical member provides an easily accessible space for accommodating a printing ink container and a pump for supplying printing ink. In particular, by using a squeegee blade instead of a squeegee roller, a particularly advantage can be obtained because the diameter of the fixed hollow cylindrical member can be such that an annular chamber defined between the fixed hollow cylindrical member and the inner circumferential surface of the printing drum is barely sufficient to accommodate the squeegee blade in the annular chamber, and the fixed hollow cylindrical member can provide a highly rigid support structure.
