ABSTRACT:
A method and apparatus for forming adhesive strips from an adhesive sheet. The apparatus may generally comprise a first forming wheel, a second forming wheel, and a cutting wheel including a plurality of circumferential grooves. The cutting wheel can be positioned in proximity to the first and second forming wheels to define a first formation interface with the first forming wheel and a second formation interface with the second forming wheel. The cutting wheel can be operable to receive at least a portion of the adhesive sheet and rotate to force at least a portion of the adhesive sheet through the first formation interface and the second formation interface such that the adhesive sheet is at least partially cut by at least one of the circumferential grooves at both the first and second formation interfaces to at least partially form the adhesive strips.
