Abstract

A conveyor system for delivering articles in succession has an endless conveyor loop, which is guided by guide rollers around a closed path including a horizontally extending run having an upstream end and a downstream end. The guide roller at one end of the horizontally extending run of the closed path and a further guide roller in a part of the path other than the horizontally extending run are mounted on a support, which is pivoted by a reciprocating mechanism so as to cyclically extend and retract the horizontal run of the path at its one end while maintaining tension in the conveyor loop. A gate is located adjacent the upstream end of the horizontally extending run to provide a sequential flow of articles to such horizontally extending run.
