Abstract: The present invention provides an integrated buffing and grinding system. The system includes a first conveyor for transporting an article to a grinding station. The article is grasped by a robot and brought into and out of contact with an abrasive surface of a sanding device. The article is then transferred by the robot to a second conveyor. The article travels along the second conveyor to a shuttle assembly. The article is then transferred by the shuttle assembly to a moveable table of a buffing device. The moveable table moves the article into and out of contact with a buffing wheel of the buffing device. The article is then transferred by the moveable table to the shuttle assembly. The shuttle assembly transfers the article to the second conveyor. The article travels along the second conveyor to an unloading station where it is unloaded.

Abstract: A container (10) for storing and dispensing, one at a time, a plurality of rolls of tissue stacked vertically adjacent one another includes tubular side walls (18,20,22,24) having a longitudinal axis and a pair of end portions (28,32) spaced from each other along the axis and being respectively joined to the side walls (18,20,22,24). One of the end portions (28) is closed to support a roll thereon and the other of the end portions (32) includes an end wall (34) inclined radially inwardly and axially relative to the axis. The end wall (34) defines a generally oval-shaped opening (36) through which to insert the rolls into the container (10) while preventing removal of such a roll from the container (10) through the opening (36).
