There is provided a process liquid coating apparatus comprising: a recording medium conveyance unit configured to convey a recording medium; a coating roller configured to rotate in accordance with the conveyed recording medium to apply process liquid on a surface of the recording medium; a pressure roller configured to cause the coating roller to apply the process liquid on the surface of the recording medium by forming an abutment part for nipping and pressing the recording medium with the coating roller; and a winding member configured to form a bent conveyance path along which the recording medium is bent with respect to a conveyance direction so that the recording medium is wound around the surface of the pressure roller, wherein the winding member is disposed adjacent to the pressure roller.

Manufacturing decorative panels by using a web-fed inkjet printer. During the feeding of the to-be-printed substrate, the tension of the substrate is controlled by a dancer unit (720) which includes a dancer roll (200), having a connector (120) on both side ends of said roll, and wherein both connectors (120) are connected to a pair of parallel guiders (110) for floating said roll along a floating path (210); and wherein the step of controlling comprises the step of moving one guider (110) of said pair of guiders (110) parallel to said floating path (210) whereby the dancer roll (200) is tilted.

The present invention includes a sheet transmission system, comprising: a sheet stacking unit, a sheet position adjusting unit, a sheet processing unit, and a sheet collection unit, arranged in series along a transmission path of a sheet; and one or more independent transmission units, each transmission unit provided between two adjacent units among above units; wherein the sheet stacking unit is configured to store the sheet to be processed; the sheet position adjusting unit is configured to adjust the position of the sheet; the sheet processing unit is configured to conduct a predetermined process to the sheet transmitted therein; the sheet collection unit is configured to collect the processed sheet; wherein when a sheet is transmitted along the transmission path, the sheet is subjected to at least one transition between the first-direction transmission state and the second-direction transition state; and wherein the sheet will not deflect in a vertical direction.

An apparatus forms stacks of interfolded sheets. First and second folding rolls receive the plurality of sheets, move the plurality of sheets through the nip, and fold the plurality of sheets into a stack of interfolded sheets downstream of the nip. A packing finger is associated with each folding roll, and the respective packing fingers move between a retracted position and an extended position relative to the corresponding folding roll with alternate movement relative to each other between the retracted position and the extended position to engage the plurality of sheets and form the stack of interfolded sheets. A fluid delivery system delivers fluid to a sheet in the plurality of sheets at or after the folding rolls.

A primer roller may include a cylinder having an outer support surface. The outer support surface support surface may have a length in an axial direction and a fixed outer diameter extending along the length. The roller may further comprise, at least at least one elastically deformable annular sleeve having an axial length less than the axial length of the support surface of the cylinder an external diameter greater than the outer diameter of the support surface of the cylinder, and an internal diameter which provides a friction fit on the support surface of the cylinder. The outer surface of the support roller comprises a plurality of fluid outlets. The outlets are distributed about the support surface. Fluid expelled from the fluid outlets enables the sleeve to be slidably positioned relative to the support surface. A priming apparatus and a print press are also disclosed.

A roll exchange chamber for exchanging a substrate roll is described. The roll exchange chamber includes a rotatable base construction being rotatable around a central axis. The base construction comprises a first roll holder for holding a first substrate roll, a second roll holder for holding a second substrate roll, and a wall for providing a first compartment and a second compartment in the roll exchange chamber. The wall is arranged between the first roll holder and the second roll holder. Further, a roll-to-roll processing system with a roll exchange chamber as well as a method of continuously providing a flexible substrate in a roll-to-roll processing system are described.
