Abstract
A paper core turnup apparatus for wrapping a web of paper about a core at high speeds includes a cylindrical core and a plurality of double sided adhesive tape strips. Each of the tape strips extends axially along an outer surface of the core, and is spaced from adjacent tape strips a predetermined distance. In a preferred embodiment, adjacent strips are circumferentially spaced approximately 12″ from one another.

A paper core turnup apparatus for winding a web of paper about a core comprising, in combination:
- a cylindrical core;
- and
- a plurality of strips of adhesive material on the core and extending axially along the core, each strip spaced from adjacent strips a predetermined distance along a circumference of the core, wherein an outer surface of each strip is completely exposed such that a web of paper wound about the core will adhere to each of the strips.
An apparatus for wrapping a web of paper about a core at a speed of at least about 4500 fpm comprising, in combination:
- a cylindrical core;
- at least three strips of adhesive material on the core, each strip extending axially along an outer surface of the core, wherein a second of the strips is circumferentially spaced approximately 12″-15″ from a first of the strips along a circumference of the core and a third of the strips is circumferentially spaced approximately 12″-15″ from the second of the strips along the circumference of the core, and an outer surface of each strip is completely exposed such that a web of paper wound about the core will adhere to each of the strips.
A paper core apparatus comprising, in combination:
- a cylindrical core;
- and
- a tape dispenser configured to dispense a plurality of double sided adhesive tape strips onto the core axially along an outer surface of the core, each tape strip being spaced from adjacent tape strips a predetermined distance along a circumference of the core, wherein an outer surface of each tape strip is completely exposed such that a web of paper wound about the core will adhere to each of the tape strips.
