ABSTRACT:
A tube material opening apparatus includes two pairs of rotatable wheels which are positioned at upstream and downstream locations within tube material. The peripheral edge of each rotatable wheel is rounded or tapered and contacts the inner surface of the tube material as the material travels in a longitudinal direction. The wheels are mounted to provide appropriate lateral tension to the tube material. The apparatus may include T-shaped bearing members or positioning rollers for maintaining the rotatable wheel positioning within the tube material.
