Competence and Innovation since 1978
BOBOTEX® Hans Ladwig GmbH & Co. KG manufactures roller covers in Wuppertal for the textile, paper, film and printing industries as well as for corrugated board production and cutting and winding technology. The product range covers almost the entire spectrum of roller covers, plus spreading and woven-lay-up felt covers as well as matched adhesive bonds and self-adhesive products. More than 90 covering materials are available from stock, with around 150 more available at short notice. The value chain ranges from problem analysis and material development through the company's own weaving mill for specialty fabrics to production on rotary vulcanizing machines, vulcanization presses, extrusion lines and embossing calenders. Materials processed include elastomers such as natural and synthetic rubber, silicones, thermoplastic elastomers, thermoplastic polyurethanes as well as PVC and NBR/PVC. Production takes place at Spitzenstraße 35 on 3,800 m²; the company supplies customers worldwide via around 50 sales partners.
