Abstract
A window (26) is masked accurately by placing the side (44) of a tape roll (42) against a window frame (28) and pressing the outer rim (46) of the tape roll (42) against the window (26). Pressure bonds the adhesive (22a) to the window (26). The side (44) of the tape roll (42) is guided and supported against the window frame (28) and tape (100) is simultaneously unwound against the window (26). The outer longitudinal periphery of the tape (100) accurately follows the corner (36).
Claims19
A roll of masking tape having a predetermined width and being suitable to mask a surface comprising:
- a) an elongated backing layer having first and second major surfaces;
- b) said first surface having as an outermost layer a pressure sensitive adhesive covering said first side at least partially;
- c) said second surface of said backing layer having thereon an anti-stick coating, covering said first side at least partially, providing an easy release of said pressure sensitive adhesive;
- and
- said masking tape being wound on a roll wherein said pressure sensitive adhesive layer faces outward from a center of the roll enabling said tape to be applied on a surface by pressing a outer rim of said roll against said surface as the roll is unwound, bonding said pressure sensitive adhesive layer with the surface and unwinding said tape out of said roll along said surface.
A method of applying a masking tape having a predetermined width and being suitable to mask a surface comprising:
- a) an elongated backing layer having first and second major surfaces;
- b) said first surface having as an outermost layer a pressure sensitive adhesive covering said first side at least partially;
- c) said second surface of said backing layer having thereon an anti-stick coating, covering said first side at least partially, providing an easy release of said pressure sensitive adhesive;
- and
- said masking tape being wound on a roll wherein said pressure sensitive adhesive layer faces outward from a center of the roll on a inner corner of two surfaces by supporting a side of said roll against a first surface of a corner and by pressing a outer rim of said roll against a second surface;
- bonding said pressure sensitive adhesive to said second surface and unwinding the tape along said second surface while simultaneously guiding said side of said roll against said first surface.
