<p>For soundproofing the noise produced by flame cutters (7) of a movable torch cutting machine (1) when cross-cutting continuous-cast slabs (3), a box-like soundproofing housing (11) can be connected via a coupling (K) to the torch cutting machine so as to move along with it, which housing is open at the bottom and covers in an enclosing manner at least the moving slab and consequently the source of noise. For the transverse movement of the cutters during a severing cut, a slit-like opening (17) is left clear in the top plate (13) of the soundproofing housing. To close off the openings in the end faces of the soundproofing housing, while allowing entry of the slab, end walls (16) with clearances corresponding to the continuous strand, or a multiplicity of hinged flaps (25) or chain aprons (27), are provided. <IMAGE></p> |
