Abstract
Apparatus is provided for protecting, transporting and dispensing standard rolls of sheet material having an open center core and an inner end bent to project obliquely into the open core to define a tang. An elongate mandrel is constructed so that it can be inserted into the open center core of a standardized roll. The mandrel end not first inserted has an abutment face for abutting the end of the roll. The mandrel includes a recess for receiving the tang. A housing which can be opened to allow a mandrel to be removed or inserted defines bearing means for the ends of the mandrel. The housing further defines a slot through which the end of a roll of material can be drawn out of the housing. The mandrel includes a cranking device by which it can be rotated.

An apparatus for protecting, transporting and dispensing standardized rolls of sheet material of the kind having an open centre core, and an inner end which is bent sharply inwardly so as to project into the open core and define a tang transverse to the roll, the apparatus comprising:
- an elongate mandrel which includes two opposed end structures and an intermediate structure bridging between the end structures, the intermediate structure and one end structure being shaped and sized so as to permit the mandrel to be inserted into the open centre core of a standardized roll from one end thereof, recess means on said intermediate structure for receiving said tang, the other end structure including a part that abuts one end of a standardized roll, thus preventing said other end structure from entering the open centre core,
- a housing sized to receive, surround and protect the mandrel when the mandrel is inserted into a standardized roll,
- bearing means mounting said mandrel for rotation with respect to said housing,
- access means on the housing through which an end of a roll of material on the mandrel can be drawn out of the housing while the mandrel rotates,
- crank means accessible from outside the housing by which the mandrel can be positively rotated, and
- protective mens operatively associated with said one end structure to protect the corresponding end of a roll against damage during mandrel rotation.
