Abstract: A screen printing apparatus includes a stencil and a doctor blade or a squeegee cooperating with the printing screen or stencil to print images on objects. A transportation arrangement is provided for transporting the objects on which the images are to be printed in a given path and direction, part of the path leading past the stencil. The transportation arrangement includes a plurality of pairs of support members which are respectively mounted on carrier elements extending laterally of the path. The carrier elements are mounted on elongated rails for movement longitudinally thereof by a distance corresponding to the spacing of the pairs of support members from one another in said direction, the carrier elements reciprocating in said direction and in an opposite direction relative to the rails.

Abstract: A screenprinting machine has at least one printing station past which an object to be printed travels in a path, and which includes a movable printing screen and a cooperating movable squeegee. A fixed rack extends along this path, and an arrangement is provided which engages and rotates the object to be printed and which includes a gear which meshes with the rack. A drive is provided for moving the squeegee at a constant rate of speed, and another arrangement serves to vary the speed of movement and the stroke of the printing screen in dependence upon the peripheral speed of the rotating object.
