[Object] To reduce heat damage to a film when a lithium layer is formed on the film by using a roll-to-roll system.

[Solving Means] A roll-to-roll deposition apparatus includes a vacuum chamber, a film travel mechanism, a lithium source, and a first roller. The vacuum chamber is capable of maintaining a reduced-pressure state. The film travel mechanism is capable of causing a film to travel inside the vacuum chamber. The lithium source is capable of making lithium melt inside the vacuum chamber. The first roller is disposed between a deposition surface of the film and the lithium source. The first roller has a transfer pattern that receives the molten lithium from the lithium source. The first roller transfers a pattern of a lithium layer corresponding to the transfer pattern to the deposition surface while being rotated.

A gravure coater test apparatus includes a gravure roll and a backup roll which are circumscribed to each other, a motor which drives the gravure roll partially submerged in a water-based pressure-sensitive adhesive for coating, a controller which adjusts the rotational speed of the motor, a doctor blade which is selected from a plurality of types to scrape the water-based pressure-sensitive adhesive from the surface of the gravure roll being rotated, and an infrared analyzer which allows at least one of the type of the water-based pressure-sensitive adhesive corresponding to the selected doctor blade, the uniformity of the coating surface, and the amount of the coated water-based pressure-sensitive adhesive to be confirmed.

A roller coater for applying paint to mainly flat panels having different lengths includes a feed roller, an application head having applying roller and a dosing roller, and a panel conveyor. The feed roller has a cover, and the application head has vertical and a horizontal covers. Rotation supports enable a coupling and decoupling of the ends of the applying roller, and translation organs provide for withdrawing the applying roller along a L-shaped path, so as to cause an initial horizontal translation with a radial distancing, and a vertical translation. The translation organs include a vertical guide and a lifting organ for the applying roller, and removable coupling terminals at the ends of the applying roller. The interaxial distance between the feed and the applying rollers is at least equal to the length of the initial translation from the rotational supports, and shorter than the minimum length of the panels.

According to one embodiment, a process for applying an adhesive material onto a barrier sheet substrate is provided. The process includes providing an adhesive material having viscosity of at least about 10,000 centipoise at 250? F. The adhesive material is applied to a multitude of cavities on a surface of a first tool with a coater unit in close proximity to the surface. The adhesive material is transferred from the surface of the first tool to the substrate supported on a surface of a second tool and pressed against the surface of the first tool.

A device for processing a strip guided along a running direction may include a roller holder disposed on a base frame so as to be pivotable about a pivot axis oriented substantially parallel to a strip running surface. A first processing roller may be disposed on the roller holder in the running direction and at a distance from the pivot axis perpendicular to the running direction and offset from the pivot axis such that by pivoting the roller holder, the first processing roller is moved toward the strip and the processing roller is moved away from the strip. A first counter-processing roller may be disposed transversely to the running direction at a further distance from the pivot axis than the first processing roller such that the first processing and counter-processing rollers interact to guide the strip if the first processing roller is moved toward the strip.

The application provides a movable apparatus for forming a thermo-softening part. The apparatus includes a first placement unit, a second placement unit, and a heat source. The first placement unit comprises one or more first rollers, which are movable in a first predetermined path. The second placement unit comprises one or more second rollers, which correspond to the first rollers. The second rollers are movable in a second predetermined path. The heat source is provided for heating an elongated thermo-softening material to a predetermined temperature. The first rollers and the second rollers are provided on opposite sides of the elongated thermo-softening material for compressing the thermo-softening material to form the thermo-softening material.

Activator applying device including a receiving pan that stores an activator for activation of a transfer film, and a spreading roller that rotates while being dipped in the activator in the receiving pan and applies the activator that has adhered to the surface thereof in a dip section of the activator applying device to the transfer pattern in a different section of the activator applying device. The activator is fed to the receiving pan in an amount greater than the amount of the activator applied to the transfer pattern, and an excessive activator is discharged through a discharge port of the receiving pan. The activator is applied to the transfer pattern with the discharge port being located on the side where the activator is drawn up from the dip section, and the discharge port being located at the position of a streak caused by uneven dispersion of the additive pigment.

A roll member having an outer circumferential surface in which a plurality of grooves are formed, wherein the plurality of grooves are arranged at an angle relative to a direction parallel to a central axis of the roll member. A coating device for coating a film member with a coating liquid, the coating device comprising the roll member. A separator production device for producing a separator in which a heat-resistant layer is laminated over a substrate. The separator production device comprising the coating device. A secondary battery production device for producing a secondary battery comprising a positive electrode plate, a negative electrode plate, and a pair of separators that sandwich the positive electrode plate or the negative electrode plate therebetween. The secondary battery production device comprising the separator production device.

A coating module for variable speed ribbon coating, the coating module including a ribbon including an inner face and an outer face; a conveyor system including a support element holding and transporting the ribbon on its inner face; a squeeze ink roller arranged in contact with the outer face of the ribbon; the squeeze ink roller including an outer layer made of elastic material; a reservoir assembly designed to hold ink thereon and to feed the squeeze ink roller with the ink, and a pressure controller including an active element for pressing the ribbon between the squeeze ink roller and the support roller along a coating zone.

Systems and methods for coating a thin film with a viscous material, such as a liquid, a paste, or an adhesive, at a desired thickness. In such a system, two films move adjacent to one another, optionally in opposite directions, atop two rollers separated by a known gap that defines a coating thickness, with the material being transferred from one film to the other. The rollers may be maintained in their relative positions by springs and/or linear actuators and positioned using linear encoders. In alternative arrangements, the material to be coated could be low viscosity material such as a polymeric solution. Air knives may be provided near the gap to create an air flow that aids in preventing the free flow of low viscosity materials outside the bounds of the film during coating.
