Abstract
All prestretching tools are connected to a common plate(22) guided by rods(15) and a locking system(30) retains the tools in a set position. In the holding system the ends(32) of the rods(15) slide in a fluid-filled chamber(33) in a fixed housing(29). A connecting bore(34) links the chamber to a storage fluid storage chamber(35). The shut-off mechanism comprises either: a) a bolt(39) of similar cross-section to the connecting bore(34) and connects with a driven piston(38); b) a slide which moves perpendicular to the sliding direction of the rods(15) and has a bore which can be aligned with the connecting bore; c) a plate, with a connecting bore, attached to the rods and guided in a bore of the housing and the connecting bore meets a closing bolt in one end position or is closed by a rotating plate; d) a driven valve plate which moves against a sealing face at the transition between the fluid-filled chamber and fluid storage chamber. In holding system a) the storage chamber(35) size is governed by a spring or compressed air-operated piston(40). A by-pass valve with adjustable throttle may be located between the fluid-filled chambers(33) and fluid storage chamber.
