ABSTRACT:
A roll of tape or paper is releaseably retained upon a roll holder by a flexible retention member, carried by the holder and normally outwardly biased to engage the core of the roll. A pivotally connected arm is biased to urge a bearing element at the free end thereof against the outer surface of the paper roll to check uncoiling of the paper sheet. The bearing element is automatically lifted and positioned in response to movement of the roll against a camming surface during attachment of the roll to the roll holder. A detachably securable auxiliary roll holder applies tape along the normally free edge of the paper sheet. Also disclosed is an auxiliary tape dispenser carried by the frame of a portable masking machine.
