Automotive & Industrial Battery Belts


For more than 30 years, the industry of automotive and industrial batteries has been constantly using our CORTAMEX products. Our 8 mm and 6.5 mm cotton belts and the 6.5 mm cotton-polyester belts are used in pasting machines to cover the grids that will be used in the charging cells.

Pasting belt

Our CORTAMEX pasting belt is a fundamental element in the manufacturing of accumulators. Its one solid weave of uniform thickness provides the stability required in order to guarantee an equal weight of plaster between the plaques.


The resistance of the joint is a priority; over more than three decades of scientific development brought as a result a unique technique that guarantees the ideal thickness that will provide great performance in this belt area. The high-quality fibers we use to build our CORTAMEX belts, allow a reduction in the quantity of paste needed for the process, meaning a significant reduction in production costs.
