<p>Between an end (3) where tensioning force is applied and a thrust bearing (5) linked to an axial guide device (AGD) (1) there is a bent-lever mechanism (BLM) (6) that is made from adjusting links (6',6'') with articulated interlinks and can be placed in a tensioning and opening position. Varying the layout of the BLM in relation to a slide rod (2) in a tensioning position determines and adjusts a clearance in different ways between the end of the slide rod where tensioning force is applied and the AGD. This clearance defines a tensioning position for a free tensioning end.</p> |
