APPARATUS FOR THE STABILIZING HEAT TREATMENT OF PLASTIC STRIPS, FOR EXAMPLE OF POLYPROPYLENE AND/OR OF POLYETHYLENE, FOR THE PRODUCTION OF STRAPS OR OF OTHER TYPES OF STRIPS

摘要

The stabilization oven (B) is provided, at one and the same end, with an upper door (3) for entry of the strips (N) to be treated, received from the upstream pulling means (A), and is provided with a lower door (4) for exit of said treated strips and at this same end said oven has means (5) for subsequently guiding the strips downwards, in such a way that they can enter, from an end that is open upwards, the cooling tank (7) which is positioned underneath the oven, and along it, and that an opening is provided at the other end for exit of the cooled strips, which rise and enter the drying means (D), and then reach the downstream pulling means (A'), the whole being arranged for the purpose of limiting the overall length of the apparatus in question.
