摘要

The invention relates to a device 1 for bracing lamellae 3 of joined-together lamellae packs 2, in which device a mechanism is arranged behind a thrust member 14 supported on the lamellae, the mechanism being formed essentially by a thrust bearing 6, capable of travelling beyond a dead centre, together with tension rod 5, helical spring 15 and spacer 8, and being embedded in a support 9 which is articulatedly connected to the thrust member 14.
