Abstract: A system of detecting and adjusting the normal force exerted by a web material around the circumferential surface of a cylinder is provided. Sensors associated with the cylinder surface are wired to a processor that compares detected normal web forces with a set value. An actuation device is activated by the processor to adjust the normal force exerted by the web by, e.g., adjusting the tension in the web material. A positioning device that preferably translates a web-wound spool is also provided as an option for the actuation device.

Abstract: Methods and apparatus to reduce or eliminate misalignment, wrinkles, and creases in coated web product. A relationship between web outgassing pressure and surface roughness of the web and web transporting rollers is developed. This relationship allows for the control over the web outgassing pressure. The ability to adjust the web tension pressure, as well as the selection of web transporting rollers with prescribed surface characteristics, allows an operator to control the degree to which the web floats over or tracks the web transporting roller. A controller, in response to pressure and tension sensors, can also provide dynamic, closed-loop control of the entire system.

Abstract: Systems and related methods are provided for modulating web tension loss at the edge of spool-hosting cavities in a cylinder by displacing the feed path and/or the exit path of the web material.

Abstract: A system for imparting and detecting mechanical energy includes a projectile and a hollow tube allowing the projectile to move therein. A portion of the projectile is allowed to emerge from one end of the tube and thereby transfer mechanical energy to a receiving entity, e.g., a wound roll of material. An actuator drives the projectile through the tube, and a first sensor detects when the protruding portion of the projectile extends from the tube to make contact with, for example, the core of the wound roll to start a timing sequence. A second sensor detects the arrival of the mechanical energy at, for example, the roll surface so that a comparison can be made between the start and end times.
