An apparatus for wrapping paper rolls as a roll handler to position a roll, a wrapping mechanism that applies a side wrapper, a header applicator that places a header against an end of the roll, and a pressure mechanism with one of a heated roller or a cooled roller that presses the outer portions of the header against the side of the roll. The heat or cooling and the pressure induce rapid bonding connection of the outer portions of the header with the side of the roll. Similarly, the process includes the steps of positioning a roll header against an end of the roll and axially rotating the roll relative to a fastening mechanism that includes a deflection mechanism that folds the outer portion of the header over against the roll, an adhesive mechanism that disposes an adhesive between the outer portion of the header and the side of the roll, and one of a heated pressure mechanism or a cooled pressure mechanism that presses the outer portion of the header against the side of the roll with the heat or cooling and the pressure inducing rapid bonding connection of the outer portion of the header with the side of the roll.

[ I claim:] [1.] A process for wrapping a large paper roll comprising the steps of:providing a paper roll, the paper roll having a roll surface and two opposing roll ends;providing wrapper, the wrapper having a width that is sized to extend between the roll ends;providing a header, the header having an inner portion that corresponds to the roll ends, having an outer portion that extends radially outward from the inner portion, and having an inside surface, the outer portion being notched to define an array of tabs that extend radially outward from the inner portion;providing a layer of heat activatable adhesive that is disposed on the inside surface of the tabs of the header;providing a hot air heater to heat activate the adhesive;positioning the heater relative to the roll to sequentially heat the tabs when the header is positioned against a roll end and the roll is rotated, the heater being adapted to blow hot air onto the tabs;providing a V-roller;positioning the V-roller relative to the roll to sequentially fold the tabs and press the tabs against the roll surface when a header is positioned against a roll end and the roll is rotated;wrapping the roll surface with the wrapper, the wrapper extending between the roll ends;then positioning a roll header a against a roll end after the roll surface is wrapped;then rotating the roll after a roll header is positioned against a roll end;then sequentially heat activating the adhesive on the tabs, by blowing hot air from the heater onto the tabs, when the roll is rotated; andthen sequentially folding and pressing the tabs over against the wrapper on the roll surface, with the V-roller, after the adhesive is heat activated.
