DEVICE FOR THERMAL TREATMENT OF RIBBON POLYMERIC MATERIAL Russian patent published in 1997 - IPC

FIELD: thermal treatment of ribbon polymeric material, in particular, for drying of tread fabric after application of adhesive. SUBSTANCE: chamber 1 is furnished with steam manifold 3, having through cylindrical pockets 4. The manifold geometric parameters are invariable. Steam supply is effected in the initial section of the device. Hollow cylinders 7 connected to the steam manifold are mounted without spaced relation in cylindrical steam-air pockets 4 on the side of the non-working surface of load-bearing slab 3. Each hollow holes 8. Steam outgoing from holes 8 gets uniformly mixed with air, the same obtained steam-air mixture acquires a homogeneous structure of eddy flow. Drying of the adhesive coating base surface of tread 2 occurs on a steam-air cushion fed from cylindrical pockets 4. EFFECT: enhanced efficiency. 3 dwg
