Abstract
A tube holder is disclosed for carrying a tube to multiple processing stations of a tube filling machine. In one non-limiting embodiment, the tube holder includes a body comprising a receptacle configured for retaining a tube. The tube includes a dispensing end and an opposite open end for filling a cavity therein with a product. A retractable tube shaping device is movably disposed in the tube holder. The shaping device is movable between an extended position and a retracted position. When the shaping device is in the extended position, the shaping device engages the tube proximate to the open end and removes ovality which might interfere with the tube filling operation. In various embodiments, the shaping device comprises a plurality of vertically retractable straightening elements that engage the sidewalls of the tube to ensure circularity of the open tube end.
