STACK OF PRESSURE SENSITIVE ADHESIVE COATED SHEETS

A stack (10) of aligned sheets (11), each of which sheets (11) includes a backing (12), a coating (13) of pressure sensitive adhesive on a lower surface of the backing by which the sheet (11) is adhered to the sheet (11) beneath it in the stack (10), which coating (13) extends along and within at le...

Zusammenfassung:	A stack (10) of aligned sheets (11), each of which sheets (11) includes a backing (12), a coating (13) of pressure sensitive adhesive on a lower surface of the backing by which the sheet (11) is adhered to the sheet (11) beneath it in the stack (10), which coating (13) extends along and within at least 12.5 mm of all of the edges of the backing (12), release means (15) providing a first adhesion zone between adjacent sheets (11) in the stack (10) and adjacent one of the edges of the sheets (11) for providing a sufficiently low release force between the adhesive coating and the upper surface of the adjacent sheet (11) in the stack to afford, when the sheet (11) is the uppermost sheet (11) in the stack (10), easy initiation of peeling of the sheet (11) from the adjacent sheet (11) in the stack, and attachment means (18) providing a second adhesion zone between adjacent sheets (11) in the stack (10) for providing a sufficiently high release force that is higher than the low release force in the first adhesion zone to firmly adhere adjacent sheets (11) in the stack (10) together and thereby hold the stack (10) of sheets (11) together during handling, while affording continued peeling away of the uppermost sheet (11) in the stack (10) after initiating of such peeling along the first adhesion zone.
