Mechanical properties For a correct job of the belt on a roller-coating machine, it is necessary to apply the proper longitudinal pressure. d n a y t i r a e n i l g n i t a r e p o t c e r r o c a e r u s n i o t d e r i u q e r s i s i h T prevent a hazardous slipping between the inner of the belt and the roller of the machinery. TANROLL belts are designed and manufactured to support this mechanical , s c i t s i r e t c a r a h c g n i t a r e p o r i e h t n i a t n i a m d n a s s e r t s granting very good results. Data related to Operating Load is also extremely important for OEMs, as related to the design of drawing and coating systems. Beyond previous mechanical properties of TANROLL belt, the 2 rubber hardnesses 23° and 36° °ShA are the most important. Typically the concerned application, as well as the variation due to single users, needs the balanced compromise among the main physical- mechanical properties of the rubber. In this view, the combination of hardness rate, abrasion resistance and tear resistance, places TANROLL belts among the best products in the world. This result was reached after studying and testing the belt with the most important OEMs and the produced compounds are perfectly matching OEMs’ and Users’ needs. Resistance to dyes and other products, including detergents. Hide coating requires several chemical products, i.e. dyes, solvents, oils and detergents for cleaning the machinery and the belt. Typically many of them are new or unknown and supposed to cause an earlier wear of the belt. There is no chance to follow any of the latest “chemical changes” of the End User, however it is possible, through laboratory tests on product, to provide indications on the related chemical resistance of TANROLL belt. Typically Oils may cause the softening of rubber and the increase in volume of the belt, while Solvents dry the belt and – consequently – cause surface cracks; besides, they increase the hardness and decrease volume. BeltTS srl Laboratories have tested TANROLL belts under certain chemical conditions and the below table is intended for OEMs and End Users. However, due to the many products, the completeness of the report is absolutely unlikely.

STANDARD DIMENSION RANGES Basically TANROLL belts have a standard range of dimension and they are valid for nearly all the main OEMs. Picture 2: TANROLL - Example of application WIN WIN S.r.l. Cap.
