Spunbond roofing
and Geotextile line

Ramina designs and manufactures complete spunbond roofing and geotextile lines starting from 100% PET polymer or flakes from recycled bottles. The line is used for the production of needle-punched fabrics for geotextile (50-700 gsm) and impregnated fabrics for roofing (80-350 gsm). The first fabrics are used in road, railway, airport, landfill constructions and civil engineering works. The second nonwovens are used for roof coverings, underflooring, plumbing, and supports for roofing bituminous membranes. The Spunbond Roofing line by Ramina uses an innovative technology that allows a lower energy consumption resulting in cost saving. In addition, the line is specifically designed to guarantee an easy accessibility for cleaning. In particular, it is possible to clean the drum dryer while the line is operating, extending line uptimes.
