1. An apparatus comprising conveying means for moving a multiplicity of articles along a path and means defining a convergent portion of said path and comprising a side guide unit along one side of said convergent portion, said side guide unit comprising a fixed frame;

  • an elongate, non-resilient, joggling member extending along one side of said unit;

    means mounting the joggling member on the frame for limited longitudinal movement;

    first actuating means coupled to the joggling member for reciprocating it back and forth longitudinally by an amount substantially smaller than the length of the joggling member;

    the improvement comprising, in combination, a rigid side guide rail;

    means mounting said guide rail on said frame generally parallel to the joggling member so that the guide rail extends along the same side of the unit;

    second actuating means coupled to the side guide rail for reciprocating the side guide rail in a direction transverse to the joggling member between an operative position in which the side guide rail lies outwardly of the unit with respect to the joggling member and a retracted position in which the joggling member lies outwardly of the unit with respect to the side guide rail; and

    control means responsive to the progress of articles along said path and adapted to cause said first and second actuating means to operate when said progress is halted by articles becoming jammed in the convergent portion of said path.
