Abstract
Two rolling bands, meaning windable and unwindable bands, are affixed to a carriage or slide which is reciprocatingly movable along a guideway. The rolling bands are each arranged to be rolled-off from a respective drum journaled at each end of the guideway. A respective wheel is rigidly coupled to each one of the drums. Two belts interconnected by a tension spring are each arranged to be wound-up upon a respective one of the wheels in opposite direction to the winding direction of the rolling band on the related drum. Without itself being subjected to substantial loading and elongation differences, the tension spring continuously holds both of the rolling bands under tension.
