<p>Apparatus for feeding relative to a molding machine a continuous stream of pallets arranged end-to-end, characterized by the provision of pallet drive means including endless conveyor means upon which are pivotally connected a series of spaced driving elements each of which includes a nose portion for engaging an appropriate rearwardly directed face on the pallets, and a follower portion adapted for engagement by stationary cam track means. The cam track means includes an inclined first portion that converges at an acute angle toward the horizontal axis of the upper run of the conveyor means, and a second portion that is generally parallel with said axis. When the follower portion of a given drive element engages the first track portion, the drive member is pivoted from a retracted position forwardly relative to the conveyor means to drive the pallets at a speed greater than that of said conveyor means. When the follower portion engages the second track portion, the drive element travels at the speed of the conveyor means, and consequently the faster travelling pallets-which are now driven by a subsequent drive element whose follower portion is in engagement with the first track portion-progress out of engagement with the nose portion of said given drive element.</p> |
