  • Patent number: 4770745
    Abstract: The front wall and support arrangement is shaped as a stiff support structure extending across the entire machine width above a slice chamber. The support structure is deformed due to its inherent weight and because of the pressures and temperatures prevailing in the slice chamber. To counteract these deformation effects the support structure is supported by a support carrier of about the same length as the support structure. To attain a substantially lower structural height, the support carrier is arranged relative to the support structure such that an intermediate space prevails between the lower wall of the support structure and the support carrier. This intermediate space accommodates force-generating support elements. Each of the force-generating support elements is provided for only a portion of the surface or area to be supported in the intermediate space.
