Station zur Herstellung einer hülsenförmigen Basis eine hülsenförmige Basis fortlaufend geformt wird und dass diese hülsenförmige Basis axial von der Station zur Herstellung einer hülsenförmigen Basis durch eine Station zu Herstellung einer druckenden Schicht bewegt wird, wobei auf die hülsenförmige Basis eine Schicht oder mehrere Schichten fortlaufend aufgetragen wird bzw. werden; zumindest jedoch eine druckende Schicht fortlaufend aufgetragen wird, während die hülsenförmige Basis die Station zur Herstellung einer druckenden Schicht passiert, so dass ein kanalloses, hülsenförmiges Gummituch von unbestimmter Länge entsteht. Der hier verwendete Ausdruck "fortlaufend" besagt, dass in der Station zur Herstellung einer hülsenförmigen Basis ein weiterer Abschnitt einer hülsenförmigen Basis hergestellt wird, während gleichzeitig in der Station zur Herstellung einer druckenden Schicht die druckende Schicht auf den zuvor gebildeten Abschnitt der hülsenförmigen Basis aufgetragen wird. Hierbei wird die hülsenförmige Basis vorzugsweise, aber nicht notwendigerweise, fortlaufend bewegt.
Basis rotiert, während sie axial von der Station zur Herstellung der hülsenförmigen Basis durch die Station zur Herstellung der druckenden Schicht bewegt wird. Gemäß einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens wird die hülsenförmige Basis nicht rotiert (d. h. sie bleibt drehfest), während sie von der Station zur Herstellung der hülsenförmigen Basis durch die Station zur Herstellung der druckenden Schicht beweg wird.
Materialschichten. Die bevorzugte Ausführungsform eines durch das erfindungsgemäße Verfahren hergestellten Gummituchs umfasst eine hülsenförmige Basis aus Metall, auf die eine komprimierbare Schicht, eine verstärkende Schicht und eine druckende Schicht aufgebracht werden.
