Abstract
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.
Claims9
A control apparatus of a web processing system that executes predetermined processing onto a web continuously existing along a movement passage,
- wherein the web processing system includes a first rotating body that rotates while being in contact with the web,
- the control apparatus controls a rotation speed of the first rotating body such that a circumferential speed of the first rotating body at a contact surface with the web matches a transport speed of the web;
- and
- wherein a distance from a rotation center of the first rotating body to a contact surface of the web in contact with the first rotating body, changes as the first rotating body rotates.
A control apparatus of a web processing system that executes predetermined processing onto a web continuously existing along a movement passage,
- wherein the web processing system includes a first rotating body that rotates while being in contact with the web, and
- the control apparatus controls a rotation speed of the first rotating body such that a circumferential speed of the first rotating body at a contact surface with the web is constant;
- and
- wherein a distance from a rotation center of the first rotating body to the web in contact with the first rotating body, changes as the first rotating body rotates.
A control apparatus of a web processing system that executes predetermined processing onto a web continuously existing along a movement passage,
- wherein the web processing system includes a first rotating body that rotates while being in contact with a non-processed surface of the web, and
- a rotation speed of the first rotating body is controlled based on a change in a distance from a rotation center of the first rotating body to a contact surface of the web in contact with the first rotating body, while the first rotating body rotates one revolution.
