| 1. A dunnage converter, comprising:
a conversion assembly that converts a stock material into a strip of dunnage as the stock material passes therethrough in
a downstream direction;
an output chute through which the strip of dunnage is discharged downstream of the conversion assembly; and
a guard disposed in the chute and movable between an open position allowing passage of the strip of dunnage through the chute
and a closed position inhibiting access to an upstream end of the chute from the downstream end of the chute, and the guard
having at a free end both a forward glide surface operative to glide along an outer surface of the strip of dunnage as the
strip moves in the downstream direction and a rearward glide surface operative to glide along an outer surface of the strip
of dunnage as the strip moves in an upstream direction opposite the downstream direction
wherein the chute includes an upstream-facing shoulder that defines a recess upstream of the shoulder, such that when the
guard is in a closed position, the free end of the guard lies in the recess upstream of the shoulder, thereby making the rearward
glide surface inaccessible from a downstream end of the chute.
