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. The difficulty of altering the lateral displacement of the respective feed bars to allow the table to transfer blanks of different sizes is overcome by using a telescopic fixing member which can be extended to an infinitesimal degree and then secured. 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. Additionally, the feed bars may be disposed in guide means for both support and to ensure precisely linear back and forth motion parallel with the central axis of the table. In this manner reliable and trouble free transfer of blanks is effected.
