Manufacture of textile reinforced low pressure push-on hose includes application of heat resistant outer layer that is removed after vulcanization

摘要

A low pressure hose that is sufficiently resilient to be held elastically on a nipple has an elastomeric inner layer reinforced by a textile layer and covered by an elastic thermoplastic. Before vulcanization a heat resistant outer support layer is applied, which is removed after vulcanization. A low pressure hose that is sufficiently resilient to be held elastically on a nipple has an elastomeric inner layer reinforced by a textile layer and covered by an elastic thermoplastic. Before vulcanization a heat resistant outer support layer is applied, which is removed after vulcanization. The elastic thermoplastic is applied by extrusion and the support layer is also a thermoplastic. After vulcanization the support layer is broken up, melted down and reused.
