Machine for thermally treating objects by heated gaseous medium - has duct, divided into overpressure and low pressure paths, with adjustable wall sections

摘要

The machine has recirculation and guiding members through which circulates the hot medium transversely in a duct. The duct is divided into an overpressure (8) and an vacuum path (10) both by the recirculation member (6) for the medium and the work (3). It has adjustable wall sections (11) on opposite sides of the work. The sections are for selective coupling of the work to the overpressure or underpressure paths. USE/ADVANTAGE - For hot air drives etc, with selective hot air passage through the work.
