ABSTRACT:
A device and method for tensioning a strip of material, such as tape, traveling from a material source, such as a tape spool, to a material user, such as a pipe or similar conduit. The device includes a first roller, a second roller, and an interconnection assembly. The first roller is positioned for non-slidingly contacting a portion of the strip of material so that the portion of the strip of material contacting the first roller travels at the same velocity as the tangential velocity of the outside surface of the first roller. The second roller is positioned for non-slidingly contacting a portion of the strip of material in the path of travel of the strip of material between the first roller and the material user so that the portion of the strip of material contacting the second roller travels at the same velocity as the tangential velocity of the outside surface of the second roller. The interconnection assembly simultaneously rotates the first and second rollers and rotates the outside surface of the first roller at a slower tangential velocity than the outside surface of the second roller so that the strip of material is tensioned between the first and second rollers. The first and second rollers may be positioned for contacting one side of the strip of material or may be positioned such that the strip of material serpentines through the rollers with one of the rollers contacting each side of the strip of material.
