Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
51 words
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.
Claim 2
Independent Claim
51 words
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.
Claim 3
Dependent Claim
38 words
A method of continuously feeding hose as described in the claim 1 wherein the magnitude of the pressure in the pressurized feeding zone is about the same as the magnitude of the pressure in the hose treatment zone.
Claim 4
Dependent Claim
32 words
A method of continuously feeding hose as described in claim 1 wherein pressure in the pressurized feeding zone is between about 80% and 100% of the pressure in the hose treatment zone.
Claim 5
Dependent Claim
20 words
A method of continuously feeding hose as described in claim 1 wherein the feeding zone is pressurized by a gas.
Claim 6
Dependent Claim
56 words
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:
Claim 7
Dependent Claim
56 words
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:
Claim 8
Dependent Claim
32 words
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.
Claim 9
Dependent Claim
32 words
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.
Claim 10
Dependent Claim
19 words
An apparatus as defined in claim 5 wherein two of the belts are vertically spaced and substantially mutually parallel.
Claim 11
Dependent Claim
22 words
An apparatus as defined in claim 6 wherein each of said two belts are mounted on an independently vertically adjustable support plate.
Claim 12
Dependent Claim
