Abstract
A tube holder is adapted to be positioned in a ring on the conveyor of the tube filling machine. The tube holder is cup-shaped and has a central, generally cylindrical, tube gripper consisting of eight upwardly extending fingers. The fingers have radially inwardly directed pads on their upper ends. The fingers lean radially inwardly. When a tube is placed in them, they flex outwardly and provide a friction grip to the tube.
