Abstract

The present invention relates a hot air circulating chamber with air-flow control system used in manufacture of thermo-plastic products such as monofilament, plastic web strips, narrow film strip, multi-filament. Conventional systems do not allow controlling temperature and air-flow in hot air channel/chamber to achieve uniformity. With the increased production speed and stringent product requirements, improved air-flow uniformity and temperature precision in the hot air oven is necessary. Invention discloses an apparatus (1) provided with air-flow path having provision of number of fans (7), optimisation of heater (6) location and increased number of air-flow regulators (8) having control levers (9). Moving web strips (5) enter apparatus into a hot air channel (4) formed between upper chamber (2) and lower chamber (3). Entry point of moving strips into the hot air channel (4) is the web-strip inlet (5A). After getting heat treated, the moving web strips (5) leave the apparatus through the web strip outlet (5B).
