Abstract: A simple, manually operable screen printing apparatus is provided, which is particularly suitable for small scale, custom printing. The apparatus permits relative adjustment between the printing screen and the workpiece in a side-to-side direction, a forward and backwards direction, a vertical direction and angularly. The apparatus also provides for replacement of the work holder with those of different sizes, to accommodate different sized articles to be printed. In essence, the apparatus comprises a main frame having upright side frame members, printing screen holding arms protruding from the main frame and adjustably mounted on cross-members of the frame for lengthwise adjustment, screen clamps on the holding arms which will releasably and adjustably secure a printing screen to the holding arms for lengthwise and angular adjustment relative to the holding arms, and a work holder on another item of the frame, mounted in a vertically adjustable manner.

Abstract: A rotary screen printing machine of the type including at least one cylindrical stencil is provided with a squeegee blade for each stencil to force a printing paint or paste through apertures in the stencil onto a textile web or sheet of paper. The squeegee blade comprises a thin flexible resilient metal strip having a thickness less than 1% of the width of the portion of such strip protruding from its holder. One edge of the squeegee blade is attached to a squeegee holder and the other or trailing edge of the blade contacts the inner face of the stencil. A covering layer of a synthetic plastic may be provided on the surface of the blade directed toward the inner face of the stencil.
