Abstract: Two coating supply tubes extend parallel to one another and run the full width of a moving substrate in the cross machine direction. Coating is supplied separately to each supply tube from opposite ends. The supply tubes discharge coating through spaced metering holes into an application chamber defined between a sidewall mounted to each supply tube. The counterflow arrangement of the coating supply tubes results in the fall off of coating pressure in one tube being canceled out by the increased pressure in the other tube. The fall off may be further counteracted by varying the spacing between metering holes the greater the distance from the coating inlet, by varying the diameter of the metering holes, or both. The tendency of the heated coating to cause a temperature gradient may be counteracted by cantilevering the applicator head on arms from a support beam through which a temperature-controlling fluid is circulated.

Abstract: An adjustable mounting system for premetered contact coating dies includes a base and a die-receiving portion movably connected to the base. During coating, the die can float a distance from the surface being coated based on the balance of forces between the die and the coated surface.

The mounting system can also include an enclosure for protecting its components.

Abstract: An apparatus and method utilize vacuum injected molding of a liquid in a plurality of mold cells for solidification therein.

Sliding of the injection head over the mold plate automatically provides self valving for sequentially evacuating and filling the mold cells from the same side of the mold plate. In a preferred embodiment, the vacuum and injection slots are linked together at the mold plate so that surface tension of the liquid restrains flow of the liquid from the injection slot to the vacuum slot while allowing gas flow therebetween for effecting the vacuum in the mold cells.

The internal walls of the sleeve are thereby coated with the fluid, while at the same time, the coating of the outside of the sleeve is prevented. The invention also relates to a writing pen comprising a coated sleeve.
