Squeege device for supplying ink in a stencil printing device
摘要:
In a squeegee device for supplying ink in a stencil printing device from the interior of a cylindrical, ink permeable printing drum which rotates around an axial line thereof with a stencil master plate wrapped around the outer circumferential surface thereof, to prevent a squeegee blade from developing a juddering movement relative to the cylindrical printing drum, and to allow the squeegee blade to sufficiently intimately contact the inner circumferential surface of the printing drum so that printing ink may be supplied to the printing drum by a prescribed amount in a stable fashion at all times, a thin spring plate is placed on a reverse surface of the squeegee blade made of a rubber-like elastic material which is in engagement with the inner circumferential surface of the cylindrical printing drum. The spring property of the thin spring plate appropriately controls the elastic deformation of the squeegee blade, and, even when the squeegee blade is made of readily deformable rubber-like elastic material, and the increase in the rotational speed of the cylindrical printing drum is increased, the squeegee blade is prevented from developing a juddering movement relative to the cylindrical printing drum.
