New complementary processes in the rolling of thermoplastics


Polimery 1998, No 10, 624


DOI: dx.doi.org/10.14314/polimery.1998.624


Summary

The design development and operation of supplementary units applied in calendering, extrusion, and casting to make sheetings are briefly reviewed. Operating conditions are specified for the complementary processes. Sheeting take-up (Fig. 2) and takeaway and piling (Figs. 3, 4) is discussed and equipment design is shown. The new processes have been practically applied and the equipment designed, constructed and operated. The equipment is used to make PVC roofings and anti-moisture insulation sheets from PVC process waste materials and PVC post-consumer articles.


Keywords: complementary systems comprising cyclic rolling, sheeting takeup and piling, production of roofings from waste PVC
