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
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 extending appendage and the second extending appendage are configured to 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 are configured to 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.

An apparatus, comprising:
- an overlay configured to cover a top surface of a bottom unit of a slot die device, the overlay comprising extending appendages that are adapted to selectively cover portions of an aperture in the top surface through which hot melt adhesive is pumped;
- and
- wherein the extending appendages are configured to control a flow of the hot melt adhesive through a slot of the slot die device when a top plate is pressed down onto the bottom unit with the overlay positioned on the top surface.
A system, comprising:
- a hot melt adhesive slot die device including a bottom unit with a top surface having an aperture and a top unit with a top plate;
- and
- a shim positioned on the top surface of the bottom unit, the shim having a plurality of extending portions that cover selected portions of the aperture;
- wherein when the top plate is pressed down onto the top surface with the shim positioned therebetween, hot melt adhesive is selectively dispensed through a slot formed between the top plate and the top surface to create varying coat weight patterns on a web of label substrate passing by the slot.
