A fluid distribution device, for applying a fluid onto a transfer roller, comprises includes an elongated chamber, at least one inlet for letting a fluid into the chamber, a longitudinal opening extending in the axial direction and adapted to face a transfer roller to allow fluid to exit the chamber and contact the transfer roller, and at least one wiper blade extending along at least a portion of the longitudinal opening. The chamber includes, at each of the two axial ends of the chamber, a wall separating the chamber from a cavity. The wall has a wall surface arranged to face the transfer roller when the device is in use. The wall is dimensioned so that the wall surface will be distanced from the transfer roller when the device is in use, so as to allow fluid to be present in a gap between the wall surface and the transfer roller.

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.

A printing apparatus includes a liquid absorption unit configured to absorb a liquid component from an ink image formed on a transfer member before transferring the ink image to a print medium. The liquid absorption unit includes a liquid absorbing member configured to absorb the liquid component, a support unit configured to support the liquid absorbing member to be movable cyclically, an applying unit arranged in a moving path of the liquid absorbing member and configured to apply a moisturizing liquid while contacting the liquid absorbing member, and a supply unit configured to supply the moisturizing liquid to the applying unit. The printing apparatus includes a control unit configured to control a supply amount of the moisturizing liquid to the applying unit by the supply unit.

According to an embodiment of this invention, liquid absorption performance of a liquid absorbing member is satisfactorily maintained while suppressing utilization of a moisturizing liquid. More specifically, before an ink image formed on a transfer member by ink discharged from a printhead is transferred, a cyclically movable liquid absorbing member absorbs a liquid component from the ink image formed on the transfer member. On the other hand, a recovery unit arranged on a moving path of the liquid absorbing member recovers absorption performance of the liquid absorbing member by applying the moisturizing liquid to the liquid absorbing member. When applying the moisturizing liquid, a condition on the surface of the liquid absorbing member is estimated and based on a result of the estimation, an application amount of the moisturizing liquid by the recovery unit is controlled.

The present disclosure is a sheet producing device for producing a multi-layer sheet by applying a coating material to a sheet material. The sheet producing device includes a radiation light source that emits radiation light, a division part that divides the radiation light into measurement light to be incident on the multi-layer sheet and reference light with which a reference surface is to be irradiated, and an optical member that emits the measurement light onto the multi-layer sheet and receives the measurement light reflected by the multi-layer sheet. An interference detector that detects interference light between the measurement light reflected by the multi-layer sheet and the reference light reflected by the reference surface, and a thickness calculator that calculates a thickness of the sheet material and a thickness of the coating material of the multi-layer sheet based on the detected interference light are further included. As a result, the tact time from the production of the multi-layer sheet to the calculation of the thickness can be shortened.

A coating device for producing an electrode with at least one double-layer powder layer on a substrate with a feed unit for feeding a substrate into a first press nip, with a first roller device for transferring a first powder as a first layer onto a first side of the substrate. The first roller device has a first metering unit, a first application roller, a first pressure roller unit, and a second pressure roller unit. A first metering gap is provided between the first application roller and the first pressure roller unit. A first press nip is provided between the first pressure roller unit and the second pressure roller unit. A second roller device transfers a second powder onto the first layer on the first side of the substrate. The second roller device being disposed downstream of the first roller device.

When a coating material is rolled between rolls to generate a a coating film, and the coating film is transferred onto the coating object, at first, a residual coating material layer based on a residual coating material is formed on each of the surfaces of the rolls, and supply of the coating material and transfer of the coating film are carried out in a state where the residual coating material layer is retained on each of the surfaces of the rolls, thereby suppressing abrasions between the rolls and the coating material.

Provided are a method and an apparatus for producing a film with a coating solution including a material whose performance is deteriorated by oxygen functional film, without performance deterioration. The apparatus for producing a functional film includes a coating device which has a backup roller and a die coater and applies a coating solution having a dissolved oxygen concentration of 1000 ppm or less and including 10000 ppm or less of an organic solvent to a flexible support transported in a state where the support is wound around the backup roller to form a coated film, a lamination device which laminates a coated surface of the coated film and the film on the backup roller, and an inert gas atmosphere forming device which forms an inert gas atmosphere in a space including the coated surface from a coating start position to a lamination start position on the backup roller.

A coating device includes: a first roll including a roll surface on which an application liquid is deposited; a first scratch off member configured to scratch off the application liquid from the roll surface of the first roll; a second roll including a roll surface configured to contact with the roll surface of the first roll, wherein the second roll is configured to rotate in a rotation direction opposite to a rotation direction of the first roll, the application liquid is transferred from the roll surface of the first roll to the roll surface of the second roll, and the second roll is configured to transfer the transferred application liquid to a steel strip; and a second scratch off member configured to scratch off the application liquid from the roll surface of the second roll.

A sealing blade includes opposite elongated edges (30, 31) and between them a flat (32) and which is adaptable to a blade holder (17) arranged in a coating applicator (25) of a coating device (21) and into contact with a moving surface (11). The sealing blade has a contact surface (33), which may be arranged against the moving surface and which is 5-15% of the width (W) of the sealing blade (10).
