  • Device and method for cutting web
    Publication number: 20020088323
    Abstract: A structure in which length-measuring roll including an elastic body is rotated by movement of a continuously fed web is employed, an amount of deformation of the length-measuring roll changes according to changes in a web speed, and a circumference of the length-measuring roll changes as a result. An error is generated in length measurement of the web, and therefore, web cutting accuracy by a cutter cannot be maintained. Therefore, timing of cutting by the cutter is controlled according to a fed length of the web and web speed information to maintain web cutting accuracy.
