Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
160 words
A device for inserting heavy rectangular prismatic bales of soft yieldable material in successive layers into a carton, said device comprising: a. an elevatable carton support having a tiltable L-shaped frame for holding a carton in filling position at a plurality of selected descending levels with a bale-receiving opening on its side and controllably tilting a filled carton to upright position, b. a bale guide in front of the bale-receiving opening being horizontally movable into the bale-receiving opening up to the full length of the carton, c. conveyor means for positioning on the bale guide bales resting on a narrow rectangular face longitudinally in front of the bale-receiving opening of the carton, and d. pusher means for pushing the bales from the bale guide into the carton, said pusher means being a hydraulically or pneumatically actuated pusher plate having a raised perimeter on the bale-contacting face to deflect the bale edge faces in converging directions away from the carton wall.
