a beam made of laminated wood, provided with a back end and a front end and supported in horizontal position above a track provided with a back end and a front end by means of a fixed supporting means associated with said back end of the track and a plurality of sliding support means along said track, which are capable of tightening points of the beam comprised between said back end and front end of the beam; and
a slider suitable for being inserted in said front end of the track, with the possibility of sliding freely, and provided with a box body with a mouth suitable for exactly receiving said front end of the beam; wherein said box body is internally provided with a plurality of blades disposed behind said mouth, said blades being suitable for longitudinally cutting the beam, progressively reducing its length, when said slider is submitted to a force capable of moving it forward towards said back end of the track; wherein, during the forward movement, said slider progressively interferes with said sliding support means of the beam, forcing said sliding support means to move towards the back end of the track.
