Abstract: The invention relates to a process and to an installation for the heat treatment of cylindrical bodies, in particular pipes, of ceramic material. During the treatment, the pipes are dried, heated and sintered, and subsequently cooled, in successively arranged chambers.During transportation through the drying zone, the heating zone and the cooling zone, as well as in heat treatment during sintering, the objects are turned about their own axis independently of the transportation rate, so that they are not only evenly heated, but a possible deformation is also prevented. This type of transportation and heating with possible heat exchange between the individual zones makes possible a rapid heating-up without detriment to the cylindrical bodies, and thus a short design length of the installation. Above all, the sintering zone, which must consist of high-value, ceramic material due to the high temperatures, can be kept very small.

Abstract: The disclosure relates to techniques for high efficiency drying of wet-processed tubular knitted fabric. The wet tubular fabric is initially spread to flat form and then guided in a controlled manner over a so-called Mach nozzle, at which high velocity gaseous medium, usually steam, at speeds approaching the speed of sound and above, is discharged directly through the fabric, which is maintained in tension as it passes over the nozzle outlet. The thus treated tubular knitted fabric, now with a greatly reduced liquid content, is then immediately directed over a second spreader device, which distends the fabric widthwise to a predetermined, uniform width, to restore the fabric width lost during wet processing and during the relatively high tension nozzle treating operation. In this damp, geometrically stabilized condition, the fabric may be directed immediately into an otherwise conventional tensionless dryer for tubular knitted fabric, where the necessary final drying operations are completed.
