The present disclosure relates to absorbent articles including a slot coated fluid positioned on a substrate, wherein the fluid is arranged in discrete pattern areas having shapes that correspond with shapes of pattern surfaces on a substrate carrier. The fluids applied to the absorbent articles herein may include various types of viscous fluids, such as adhesives and wetness indicator compositions, and may also include a color that is different than the substrate onto which the fluid is applied.

A material deposition system (10, 30) for depositing material on an electronic substrate (12) includes a frame (20, 32), a support (22) coupled to the frame and configured to support an electronic substrate (12) during a deposit operation, a gantry (24, 38) coupled to the frame (20, 33), and a deposition head coupled to the gantry (24, 38). The deposition head (14, 36) is movable over the support (22) by movement of the gantry (24, 38). The deposition head (14, 36) includes a chamber (1110) configured to hold material, an actuator (1130) configured to push a volume of material out of the chamber (1110), a needle (120) extending from the chamber (1110) and terminating in a needle orifice (130), and at least two air jets (140, 150) located on opposite sides of the needle orifice (130). A desired volume of material is formed at the needle orifice (130) in response to the actuator (1130), and each of the at least two air jets (140, 150) produce a timed pulse of air to create a micro-droplet from the desired volume and to accelerate the micro-droplet to high velocity.

A system of pointillist painting comprises an automated 3-D positioning system disposed proximate a painting surface, a colorant dispenser coupled to the gantry structure and having a dispensing tip in fluid communication with a colorant chamber, the gantry structure operable to move the colorant dispensing tip to a specified position of the painting surface, where the colorant dispenser is operable to apply a specified amount of a colorant to the painting surface and creating a dot having a two-dimensional coverage and three-dimensional profile at the specified position. The colorant dispenser further comprises a piston disposed in the colorant chamber, and a push rod coupled to the piston operable to advance the piston toward the dispensing tip to exude the specified amount of colorant onto the painting surface.
摘要:
L'invention se rapporte à une installation pour le dépôt d'un film de particules ordonnées (4) sur un substrat en défilement (38), l'installation étant conçue pour permettre le dépôt, sur le substrat, d'un film de particules ordonnées s'échappant par la sortie de particules d'une zone de transfert présentant une première largeur (L1). Selon l'invention, l'installation comporte en outre un dispositif accessoire (100) en forme de tête de dépôt, prévu pour obturer ladite sortie de particules et conçu pour permettre le dépôt, sur le substrat (38), d'un film de particules ordonnées s'échappant par une extrémité (62) d'un canal de transfert de particules (56) de cette tête de dépôt, cette extrémité présentant une seconde largeur (L2) strictement inférieure à la première largeur (L1).
