Abstract: Known screen printing machines, which have a continuous support for the squeegee, have the disadvantage that the printing is impaired when the support bends. This also applies to constructions with a squeegee support which is independent of the support and the weight of which, in the case of an asymmetrical squeegee arrangement, results in an uneven loading of the squeegee. According to the invention, the support is therefore disposed rigidly at the guide rails, and pneumatic double-action cylinders are arranged directly at the support, the squeegee being fastened at the cylinders so that its angle can be adjusted. A bending off the support does not influence the printing quality, even if the squeegee is not arranged in the center of the support.

Abstract: A screen printing machine is disclosed which has a screen frame mounted on a swivel mount shaft. The swivel shaft for the screen frame extends through the center plane of the screen frame which extends perpendicularly with respect to the movement of the squeegee. Devices are provided which can raise the screen frame on both sides of the swivel shaft. By means of this construction, while the advantages of a compensation of errors are maintained, the screen printing machine may be used for movements of the squeegee in both directions. The new screen printing machine is particularly well suited for the printing of printed circuit boards.

Abstract: A screen printing apparatus is provided for transferring sheet materials from a supply area to a printing table. The apparatus has a pair of grippers which are guided jointly over the printing table in a timed manner in order to grip a blank sheet at a feeding table and pull it over the printing table. The two grippers are separately guided above the printing table in such a way that their movements take place in opposite directions to one another and that one of the gripper fails passes over the other one in the area of the center of the printing table. This design has the advantage that during the transport by a first gripper of a sheet to be printed on the printing table, a second gripper rail already returns to its starting position. Therefore, when the printed sheet is removed from the printing table, a new sheet can be placed thereupon immediately. Idle times for the conveying of the sheets to be printed are eliminated with the use of only two grippers.
