Abstract: Bed clothing in panels which extend the length or width of the bed and which can be fastened together to make up bed cloths, and which can be fully separated from each other for laundering. Where the panels extend longitudinally in the bed, and the panels have effective widths of about 19 inches to about 23 inches, the panels can be used to make up bed clothing which fits all standard size beds within 10 inches of conventionally-used bed clothing widths. The panels can have adjustable widths (W) which enable the user to assemble a bed cloth to more closely approach the conventionally-used bed clothing widths. A longitudinally-extending panel can be segmented so as to be separable into two or more panel pieces along transversely-extending edges of the respective panel pieces.

Abstract: This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to controlling tension in such continuous webs during the processing operation. Tension is controlled in a dancer control system by connecting a corresponding dancer roll to a servo motor or the like, sensing position, tension, and velocity parameters related to the web and the dancer roll, and providing active gain force commands to cause translational movement in the dancer roll to control temporary, short-term tension disturbances in the web. In some applications of the invention, the dancer control system is used to attenuate short-term tension disturbances. In other applications of the invention, the dancer control system is used to create short-term tension disturbances.
