Abstract

Installation for the manufacture of a sintered strip of plastic material powder, especially for the manufacture of separators for accumulators, in which the plastic material powder is applied in a layer on the upper section of a metallic endless conveyor belt, circulating, and the powder layer, through this belt, for the sintering is conducted through a tunnel oven, characterized in that a hot air circulation system is provided for heating the metallic conveyor belt in the tunnel oven., which has a fan, connected through circulation lines, to the tunnel oven, and an external heat exchanger, the entire heating path being inside the tunnel oven subdivided into heating sectors, located one behind the other in the longitudinal direction of the conveyor belt, which are connected in parallel according to the technique of the current and downward, as well as laterally e are limited by the inner wall of the lower part of the oven and immediately upwards by the metallic conveyor belt, adjusting the pressure of the hot air, which flows, at the end of each heating sector, at least equal to the atmospheric pressure .
