A web processing system which includes two rollers configured to rotate at the same phase while being in contact with a web which continuously exists along a movement passage and a suppressing mechanism for suppressing a tension variation of the web between the two rollers.

Processing system and control method for handling continuous sheet of material

In order to reduce variations in pressing force of a printing nip to make the printing pressure uniform, an apparatus that performs printing on a substrate using a roll-to-roll method according to an aspect of the present application includes: an ink supply member that supplies a printing ink; a blanket cylinder () that transfers part of the ink, which has been supplied from the ink supply member and applied on a surface of the blanket cylinder, onto the substrate; a roller mold () that removes part of the ink applied on the surface of the blanket cylinder (); a base () on which the blanket cylinder () is fixed; a slider () that supports the roller mold () and moves on the base (); a moving resistance reduction device () that reduces a moving resistance of the slider () relative to the base (); and a roller mold nip device () that applies, to the roller mold (), a nip pressure against the blanket cylinder ().

Printing apparatus

In order to provide, to a roll-to-roll printing apparatus which seamlessly performs printing on a base material using a roll-to-roll method, performance for finely controlling the tension of the base material, the roll-to-roll printing apparatus includes a drive roll () that supplies a base material (B) to a plate cylinder, a drive roll actuator that rotates the drive roll (), a dancer actuator () that changes a path line length of the base material (B) to vary the tension of the base material (B), a tension detection device () that detects the tension of the base material (B), and a tension control device () that controls the drive roll actuator and the dancer actuator () in accordance with a result of the detection by the tension detection device () to compensate for a variation in the tension of the base material (B). When compensating for the variation in the tension of the base material (B), the tension control device () uses the drive roll actuator to perform relatively rough control, while using the dancer actuator () to perform relatively fine control.

Roll-to-roll printing apparatus

A control apparatus of a web processing system that executes predetermined processing onto a web continuously existing along a movement passage, in which the web processing system includes a rotating body that rotates while being in contact with the web, and the control apparatus controls a rotation speed of the rotating body such that a circumferential speed of the rotating body at a contact surface with the web matches a transport speed of the web.
