A system and methods for manufacturing a dry electrode for an energy storage device are disclosed. The system includes a first dry electrode material delivery system configured to deliver a dry electrode material, a first calendering roll, a second calendering roll, and a controller. The second calendering roll is configured to form a first nip between the first calendering roll and the second calendering roll. The first nip is configured to receive the dry electrode material from the first dry electrode material delivery system, and form a dry electrode film from the dry electrode material. The controller is configured to control a rotational velocity of the second calendering roll to be greater than a rotational velocity of the first calendering roll.

An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

A device for applying abradable material to a surface of an annular casing of a turbine engine, wherein the casing extends along a longitudinal axis, comprises a support equipped with first guiding means capable of guiding the support in relation to the casing in a radial direction in relation to the axis of the casing. The support is equipped with second guiding means capable of guiding the support in relation to the casing in an axial direction. The device further includes an application roller pivotally mounted in relation to the support in the axial direction and adjustment means allowing adjustment of the position of the roller in relation to the first guiding means, in the radial direction.

Adhesion of particles having a large particle size contained in the slurry to a surface of a strip member is suppressed. A slurry application method includes: spraying a slurry from a nozzle onto one or both of a traveling strip member and a roll; and applying the slurry to a surface of the strip member by pressing the roll against the surface of the strip member, wherein a spray angle θ is set to 0° or more and 50° or less, a distance d in a conveyance direction of the strip member between an intersection point P1 and a rotation center P2 of the roll is 100 mm or less, and a height h from the surface of the strip member to the intersection point P1 is ½ or less of a diameter of the roll.

Systems and methods for dispensing liquid materials as may be used in applications for coating flexible films and the like. Such a film may be coated by dispensing a rheological material onto its surface while drawing the film through a gap between a pair of rollers. The gap defines the thickness of a layer of the material applied to the film and is maintained at a desired width by microwires positioned through the gap. Another film across the gap from that to which the rheological material is applied aids in the coating of the layer and a contact area of the second film may be adjusted relative to the gap, e.g., when changing materials or when the coating film becomes abraded or deformed.

This application discloses an electrode plate rolling apparatus and an electrode plate rolling method that are configured to roll an electrode plate. The electrode plate includes a coated region and an uncoated region. The electrode plate rolling apparatus includes a roller group, a heating part, and a cooling part. The heating part is configured to heat the electrode plate, and the cooling part is configured to cool the electrode plate. The heating part further includes an extension assembly, and the extension assembly can extend the uncoated region when the heating part heats the electrode plate. The electrode plate passes through the cooling part after passing through the heating part. The heating part and the cooling part are configured to reduce a difference between an extensibility parameter of the uncoated region and an extensibility parameter of the coated region.

Calendering devices and processes are provided that process a fluid that has been rendered adhesive or is inherently adhesive, wherein processing typically involves forming of the fluid into a film of defined layer thickness and applying the fluid to a carrier material, post-calendering, or a combination of at least two of the above-mentioned processes. The devices may comprise a feed device for feeding the fluid, a multi-roller mechanism having at least two calendering rollers, and at least one calendering nip for processing the fluid, in which at least one of the at least two calendering rollers has an average roughness depth Rz of between 5 m and 15 m or between 9 m and 13 m.

An asphalt shingle manufacturing machine that includes a curtain die for applying a liquid release layer on an asphalt coated substrate. The moisture of the liquid release layer evaporates leaving a dispersed solid particulate release layer. The curtain die includes a first body section and a second body section with a shim disposed between the body sections to define a distribution channel. The second body section may include chamber manifold defined therein to store a volume of liquid release agent. The distribution channel places the chamber manifold in fluid communication with a discharge outlet of the curtain die in order to disperse a volume of liquid release agent from a chamber manifold out of the discharge outlet. The shim may be configured to define a width of the distribution channel to determine the flow rate and discharge pattern of the liquid release agent.
