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: 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.
