Abstract: There is described a feed mechanism for a feed table for translating sheet metal blanks from as automatic notching curling and beading machine to a bodymaker in the process of tin box manufacture. The mechanism comprises a pair of reciprocally drives longitudinal feed bars provided with spring loaded pawls in their upper surfaces which engage behind the edges of the blanks during a forward motion and slide beneath the blanks during a reverse motion.

In practice, both the longitudinal feed bars are secured to a reciprocally driven transfer table within the stationary feed table, and it is the connection of the feed bars to this table that is achieved with telescopic fixing members.

Abstract: A transfer system is provided for press facilities with several successive press stations. The transfer system has divided cross traverses which, with respect to the transport direction, can be moved from the front and the rear into the tool. Each tool includes two respectively transversely divided traverses. For receiving and depositing the workpieces, the cross traverses are adjusted toward and away from one another. In addition, when the tool is closed, the cross traverse are laterally moved past the tool. As required, they may be changed for this purpose into an overtaking position, which can be carried out, for example, by a swivel drive. The transfer system permits a shortening of the minimum time for which the tools must be open with respect to the transfer system and thus allows an increase of the stroke number of the press.
