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.

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.

A gluing group for a rewinding machine for applying glue to an end edge of a log comprising a delivery roller (12) supported in an idle manner by supporting and translation guiding elements (15, 16), delivery means (20) for delivering a glue line (11) on one of the generatrices of the delivery roller (12), a linear actuator (30) connected to said delivery roller (12) to transmit the approaching and distancing movement of the delivery roller (12) against the paper (11) being wound onto a contrast roller (115).

A rewinding machine comprising such gluing group and a related method for gluing the end edge also form part of the invention.

At the time of forming a paste layer on a substrate sheet by use of three rolls placed at right angles, in order to offset a variation amount of a first gap due to thermal expansion of the rolls, a variation amount in a given detection period is calculated by use of outputs of a first sensor configured to detect a coating film surface of a second-roll coating film of a second roll and a second sensor configured to detect a second-roll surface, and the first roll is moved by use of a first-roll moving mechanism.

The present disclosure relates to the technical field of lithium-ion battery (LIB) separator preparation and in particular to a dispensing device for a LIB separator. The dispensing device for a LIB separator mainly includes a coating adhesive transferring device, a feed amount controller, and a planar bottom roll. The coating adhesive transferring device includes an adhesive accommodating device and a relief roll. Accommodating grooves for accommodating adhesives are provided on the adhesive accommodating device. Transferring protrusions are arranged on a rolling surface of the relief roll. The relief roll is located between the adhesive accommodating device and the planar bottom roll. The transferring protrusions are inserted into the accommodating grooves at a place where the relief roll contacts the adhesive accommodating device. The feed amount controller is configured to detect and control the feed amounts when the transferring protrusions are inserted into the accommodating grooves. The planar bottom roll is located under the relief roll. A film passing gap for allowing a coating film to pass through is provided between the planar bottom roll and the relief roll. The thicknesses of coating layers formed with the dispensing device are larger, and thicknesses and coverage rates of adhesive points are controlled simply and conveniently.

In a coating system, two rollers are arranged adjacent to one another. A donor foil with rheological material dispensed thereon is advanced through a gap between the two rollers. Such gap spreads the dispensed material over the donor foil, coating the donor foil with a layer of the material with a uniform thickness associated with the gap width. Each roller is supported on a holder. Adjustment of the gap width may be effected by keeping the position of one of the holders fixed, while horizontally translating the position of the other holder. The position of the translatable holder may be adjusted by pistons and linear actuators. The pistons may bias the moveable holder towards the stationary holder. The linear actuators mounted on the moveable holder may extend respective arms against the stationary holder, thereby countering the biasing of the pistons and pushing the moveable holder away from the stationary holder.

The invention relates to a device for producing a web of corrugated cardboard comprising a first corrugating roller for producing a corrugated web. The device further has a glue application roller for applying glue to the corrugated web. The glue application roller is associated to the first corrugating roller so as to form a gap and is displaceable relative to the first corrugating roller in order to influence the glue application quantity. The device further comprises a displacement device for displacing the glue application roller relative to the first corrugating roller and a pressing device for pressing a laminating web against the corrugated web. It is further provided with a regulating device which is in signal connection with the displacement device, a gap regulating unit in order to adjust a gap width of the gap between the first corrugating roller and the glue application roller, and a contact force regulating unit in order to adjust a contact force applied to the first corrugating roller by the glue application roller.

The present disclosure discloses a coating device. The coating device includes a coating roller, a scraping roller, and a blocking assembly. The scraping roller and the coating roller are arranged side by side, and a gap is provided between the scraping roller and the coating roller to allow a slurry to pass through. The blocking assembly is arranged at an outer side of the coating roller and an outer side of the scraping roller. The blocking assembly includes a support and a blocker mounted at the support. The blocker includes a cooperation portion cooperating with the coating roller and an engagement portion cooperating with the scraping roller. A first end of the cooperation portion and a first end of the engagement portion are connected and form an angle portion. The angle portion extends into the gap.
