ABSTRACT:
An apparatus for wrapping rolls of paper includes a wrapping material feed system for deliverying sheets of wrapping material and includes spaced apart vacuum belts and a conveyor for delivering the rolls to be wrapped in a path which intersects that of the vacuum belts. The rolls are successively moved downwardly between the belts for displacement of the roll and the wrapping material into one of a series of transport buckets carried on an endless conveyor. The ends of the wrapping material are folded over the roll after which the buckets transport the rolls through successive stations where pins are partially inserted into the core of each roll as the wrapper is folded over the ends of the rolls and about the pins which are then fully inserted to move the wrapped ends a slight distance into the core. The pins are then removed and rotating members are moved into engagement with sides of the roll for fully inserting the folded ends of the wrapping material into the core.
