Abstract:
There is provided an apparatus for applying constant pressure to a plurality of anvil rollers for crush-scoring used in combination with crush-scoring cylinders having protrusions extending from the surface thereof. Each anvil roller is supported in a substantially frictionless manner and the constant pressure is supplied by a flexible diaphragm acting on a plunger which can move substantially without friction in a pneumatic cylinder.
Abstract:
A die coater for applying a material to a web is provided including a die for applying the material to the web in an application region; and a plurality of interconnected rolls selectably positionable in the application region to serve as a backup roll for the web for the application of the material, In addition, or in the alternative, the die coater includes a plurality of interconnected dies selectably positionable in the application region for applying the material to the web; and a backup roll for the web in the application region, wherein a selected one of said interconnected dies selectably positioned in said application region is adjustable to adjust an angle at which said material is applied to said web through said selected die.

Abstract:
An apparatus for forming bands of reduced coat weight of a coating on a coated web that is moving through a laminating machine includes a supply of fluid and a nozzle for directing a stream of fluid from the supply toward the web, said nozzle having a relatively small outlet aperture for directing a relatively narrow width stream of fluid toward the web compared to the width of the web to impinge on the web to reduce the coat weight over a relatively narrow width band. The bands may be formed in the machine direction of travel of the web, across the width of the web in a direction other than the machine direction and may be of various width and may be precisely or randomly placed. The reduced coat weight areas may be narrow bands or broader areas of the web. A method for forming a band of reduced coat weight of a coating on a coated web includes directing a stream of fluid toward the web and extending over a relatively narrow width of the web compared to the width of the web to impinge on the web to reduce the coat weight over a relatively narrow width band or over a relatively broader area of the web.
