Printing drum assembly for a stencil printing device
First Claim
1. A printing drum assembly for a stencil printing device, comprising:
- a frame of a stencil printing device;
a hollow cylindrical member fixed to and supported by said frame;
a printing drum having an inner circumferential surface rotatably supported by said hollow cylindrical member at two axially spaced positions thereof, said printing drum including an ink permeable outer shell;
a printing ink container disposed inside said hollow cylindrical member; and
printing ink supplying means for feeding printing ink from said printing ink container to said inner circumferential surface of said printing drum.

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.
