Abstract
A label with varying degrees of adhesive coat weights is provided. A backside of the label includes first channel areas in which there is no adhesive. The backside of the label also includes second channel areas in which the adhesive is flood coated. Furthermore, the backside of the label includes third channels in which the adhesive is disposed in a coat weight that is less than what is achieved via flood coating.
Claims20
A label, comprising:
- a substrate;
- an adhesive disposed on a backside of the substrate in multiple channels defined in the backside, wherein first channels include the adhesive disposed on the backside in a first coat weight and second channels include the adhesive disposed on the backside in a second coat weight;
- and
- the backside of the label further includes third channels that are devoid of any of the adhesive.
1 more element
An apparatus, comprising:
- an overlay adapted to be affixed to a top surface of a bottom unit for a slot die device of a label press;
- and
- the overlay, comprises:
- a first extending appendage situated at a first end of the top surface of the bottom unit;
- a second extending appendage situated at a second end of the top surface of the bottom unit;
- and
- additional extending appendages situated between the first extending appendage and the second extending appendage, wherein each additional extending appendage sized to cover certain portions of an aperture of the top surface, wherein hot melt adhesive is pumped up through the aperture of the top surface and onto remaining portions of the top surface;
- wherein when a top plate for a top unit of the slot die device is pushed down onto the top surface of the bottom unit under control of the label press, the hot melt adhesive is dispensed through a slot between an underside of the top plate and the top surface;
- wherein the first and second extending appendages block a flow of the hot melt adhesive out of the slot at the first end and at the second end;
- wherein the additional extending appendages one or more of:
- block the flow of the hot melt adhesive out of the slot and partially restrict the flow of the hot melt adhesive out of the slot.
8 more elements
A method, comprising:
- causing a machine to cut out an overlay from a piece of material to form an overlay for a top surface of a bottom unit associated with a hot melt adhesive slot die device of a label press;
- wherein causing further includes cause the machine to cut out two or more extending appendages sized to cover portions of an aperture of the top surface, liquid hot melt adhesive is dispensed through the aperture by the bottom unit and forced out a slot of the hot melt adhesive die slot device when a top plate of a top unit for the hot melt adhesive slot die is forced down onto the top unit with the overlay in between the top surface of the bottom unit and an underside surface of the top plate of the top unit.
