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.
Claims5
A web processing system comprising:
- two rollers configured to rotate at a same phase while being in contact with a web which is continuous along a movement passage;
- and
- a suppressing mechanism for suppressing a variation in a tension of the web between the two rollers.
A control method of a web processing system including two rollers that are configured to rotate at the same phase while being in contact with a web which is continuous along a movement passage, and a dancer system that includes a dancer roller disposed between the rollers, the method comprising:
- rotating the two rollers at a same phase in a state where the dancer roller is controlled to be kept at a certain position and detecting a force applied to the web between the two rollers;
- and
- rotating the two rollers at the same phase in a state where a force applied to the dancer roller is controlled based on the detected force.
