20190100399 · 2019-04-04 · ·

A conveying apparatus includes: a conveyor including a brake to apply brakes to a web, the conveyor configured to convey the web while giving tension to the web by applying brakes to the web using torque of the brake; and a controller configured to control the conveyor. The controller performs at least one of a first control or a second control. The first control includes determining a first torque of the brake during acceleration of the web to be a value depending on a first inertial load at the conveyor during the acceleration of the web. The second control includes determining a second torque of the brake during deceleration of the web to be a value depending on a second inertial load at the conveyor during the deceleration of the web.

Method of Controlling Operation of a Winder for a Fiber Web

This invention relates to a method of controlling the operation of a winder in which method while forming at least one fiber web roll the fiber web is brought on the web roll via a nip formed by a first support drum and the web roll, which first support drum is driven by a first drive assembly (20) applying controllable torque to the drum and the winding force is applied to the web roll by a second drive assembly (22). In the method the second drive assembly (22) is controlled based on the indicative speed difference of the second drive assembly (22) and setting a friction coefficient for determination of maximum winding force.
