Abstract:
1. A vertical bagging machine comprising: first and second vertically extending rollers defining a nip therebetween, wherein a folded sheet of bagging material feeds out from the nip in a first configuration of the folded sheet having a first folded half, a second folded half, a horizontal fold therebetween with the first and second folded halves extending downward from the horizontal fold, a first surface of the folded sheet being an exterior surface of the first configuration, and a second surface of the folded sheet being an interior surface of the first configuration; and a spreader chute arranged to receive the folded sheet as the folded sheet emerges from the first and second rollers, wherein the spreader chute comprises a transition zone and includes a first guide plate and a second guide plate, the second guide plate being parallel with and spaced apart from the first guide plate to define a laterally accessible loading space therebetween, each of the first and the second guide plates including an inner surface and an outer surface, wherein the first folded half is received over the inner and the outer surfaces of the first guide plate, and wherein the second folded half is received over the inner and the outer surfaces of the second guide plate, wherein the first and the second guide plates invert the folded sheet from the first configuration into a second configuration in the transition zone, with the second configuration having a vertical fold, the first surface being an interior surface of the second configuration, and the second surface being an exterior surface of the second configuration.
