Patent ID: 6900436

Claim:
A wire tensioning mechanism for tensioning a wire having an end one and an end two, in a machine, wherein said wire is fixed to the machine at end one and has a means for attachment on end two, comprising: a groove on the machine, wherein said end two of the wire is laid in said groove to align the wire to a desired position; a slide block which is slidably mounted to the machine at the wire end two such that said slide block slides parallel to the wire, having a slot which is wider than the wire but narrower than the means for attachment such that when said slide block is mounted on the machine, the wire end two can be slid into said slot such that pulling said slide block in the direction away from the wire forces the means for attachment against the slot, but does not allow the means for attachment to pass through a spring which is mounted between the machine and said slide block such that said spring exerts a force on said slide block in the opposite direction of the force which the tensioned wire exerts on said slide block, such that the force of said spring can cause said slide block to slide, and wherein said spring is chosen such that the force exerted on said slide block causes the wire to achieve the desired tension.
