  • Patent number: 4309232
    Abstract: A method and apparatus is provided for continuously fabricating a high pressure hose, or the like, which includes axially advancing interconnected hollow mandrels through a plurality of winding stations wherein all of the hose building components are helically wound upon the advancing mandrels. A heat shrinkable webbing may also be wound upon the advancing mandrels so as to cover the hose components. The mandrels are then separated, and steam is introduced into the interior of the mandrels to effect curing of the hose components, with the shrinkable webbing acting to radially compact the components to remove air pockets and smoothly conform the innermost component against the mandrel. A method and apparatus is also provided for unwinding the shrinkable webbing from the hose after curing, and which includes a drive control system which advances the hose through an unwinding deck while insuring that the webbing being withdrawn from the hose is aligned with its take-up spool.

  • Patent number: 4035212
    Abstract: Process of and composition for forming a hard, rubber-like covering on the ends of metal rolls utilized in the textile, paper or other industry including the following. A semi-liquid, elastomeric, polymeric, coating composition is provided having a viscosity sufficient to prevent sagging from the ends of the metal roll when applied thereto while being sufficiently liquid to dispense easily in a continuous stream and being cross-linkable to form a hard, rubber-like material. Cement is applied onto the ends of the metal roll and the semi-liquid coating composition is applied onto the cemented ends. The coating composition is cross-linked by heating to cure and solidify the semi-liquid composition to form a hard rubber-like coating on the ends of the metal roll.
