Abstract: A screen printing machine comprises a support frame comprising vertical and horizontal members and having a rear side, a front side spaced horizontally forward therefrom, and a plurality of stanchions projecting upward between the front and rear sides and an auxiliary frame lying and horizontally movable on the stanchions and projecting forward past the front side of the support frame. A screen is clamped to the auxiliary frame so that the screen is cantilevered on and projects forward beyond the front side of the support frame and lies fully forward of the front side of the support frame. A platen disposed below the screen and forward of the front side of the support frame is pivotal on this support frame at its rear side about a pivot axis so that the platen projects wholly beyond the front side of the support frame and access to the platen and the screen is afforded on all sides thereof except for rear edges of the screen and the platen which are proximal to the support frame.

Abstract: Endless V-shaped belt, provided with longitudinal elements allowing the increase of the power transmitted with a conventional belt, comprises a rigid transverse part, integral with the longitudinal armature, used for the transmission of the motion by contact and pressure in the groove of a pulley, each transverse part being provided as a thin V-shaped plaquette (1), cut at the upper or lateral portion thereof to allow the passage and seating of the longitudinal armature.
