A method for wrapping a roll having a pair of spaced roll ends and an outer roll surface extending between the roll ends.
Claims22
A wrapped paper roll, comprising:
- a paper roll having a lower roll end and an upper roll end, spaced-apart from the lower roll end, and an outer roll surface extending between the lower and upper roll ends;
- a wrapper having a first section covering the outer roll surface of the paper roll, the first section having an inadhesive inner face in contact with the outer roll surface, and a second section covering at least a portion of the lower roll end, the second section having exposed adhesive on at least one side of the wrapper, the second section being crimped over the lower roll end and forming folds with interior fold sections wherein portions of the wrapper with the exposed adhesive face each other and are bonded together in adhesive-to-adhesive contact preventing liquid infiltration therebetween;
- and
- at least one of:
- an interior roll header interposed between the lower roll end and the crimped second section of the wrapper, the interior roll header having an outer face with adhesive properties in contact with the exposed adhesive and being bonded to the crimped second section of the wrapper;
- and
- an exterior roll header superposed exteriorly to the crimped second section of the wrapper, the second section of the wrapper comprising the exposed adhesive on an outer face thereof, the exterior roll header having an inner face with adhesive properties in contact with the exposed adhesive and being bonded to the crimped second section of the wrapper.
