Abstract
Limp, elastomeric hose is fed through a pressurized chamber having an inlet and an outlet opening, the outlet opening leading directly to a pressurized hose treatment zone. Seals at both the inlet and outlet opening of the chamber simultaneously permit continuous passage of hose and prevent escape of the pressurizing fluid from the chamber and from the treatment zone. The hose is driven from the inlet end of the chamber up to and out of the outlet seal of the chamber, and into the treatment zone by a pair of vertically spaced substantially mutually parallel, endless, flexible belts disposed within the chamber.
Claims9
A method of continuously feeding hose in a direction parallel to the longitudinal axis of the hose into a pressurized hose treatment zone, which comprises:
- a. pulling the hose into a pressurized feeding zone adjacent the treatment zone;
- b. pushing the hose into the hose treatment zone from the feeding zone.
Apparatus for feeding elastomeric hose into a pressurized zone, the apparatus comprising:
- a. a chamber having an inlet opening and an outlet opening;
- b. means to pressurize the chamber;
- c. a plurality of endless, flexible belts within said chamber;
- d. means to drive said belts;
- e. an entrance sealing device at the inlet opening adapted to:
- 1. permit continuous passage of elastomeric hose from said chamber while simultaneously;
- 2. preventing escape of pressurizing fluid from said chamber and simultaneously;
- 3. preventing escape of pressurizing fluid from said pressurized zone.
