Abstract
A pipe lining apparatus having a resin-impregnated reinforcement filament that is helically wound onto the inner surface of a tubular first lining layer disposed within a pipe by an inverted filament winding apparatus, the apparatus having a spring-loaded, articulated frame which maintains an orbiting applicator assembly.
Claims19
An inverted filament winder apparatus adapted to apply a filament to the inner wall of a pipe or pipe liner, said apparatus comprising:
- an articulated frame comprising a pair of base members mounted to a rotatable shaft, each of said base members comprising a first end and a second end;
- a first set of spring-loaded arm members pivotally mounted to the first ends of said base members, and a second set of spring-loaded arm members pivotally mounted to the second ends of said base members;
- said first set of spring-loaded arm members extending from said base members in a first direction and said second set of spring-loaded arm members extending from said base members in a second and opposite direction;
- an orbiting applicator assembly comprising a compression roller, said orbiting applicator assembly mounted to said first set of spring-loaded arm members such that said orbiting applicator assembly is outwardly biased;
- an orbiting centering assembly, said orbiting centering assembly mounted to said second set of spring-loaded arm members such that said orbiting centering assembly is outwardly biased;
- said orbiting applicator assembly and orbiting centering assembly being positioned on opposite sides of said rotatable shaft;
- a spool retaining a length of heat-curable filament;
- wherein said filament is passed onto said compression roller for application to the inner wall of a pipe or pipe liner.

An inverted filament winder apparatus adapted to apply a filament to the inner wall of a pipe or pipe liner, said apparatus comprising:
- an articulated frame comprising a pair of base members mounted to a rotatable shaft, each of said base members comprising a first end and a second end, wherein said rotatable shaft defines an axis and said pair of base members are separated axially along said rotatable shaft;
- a first set of spring-loaded arm members pivotally mounted to the first ends of said base members, and a second set of spring-loaded arm members pivotally mounted to the second ends of said base members;
- said first set of spring-loaded arm members extending from said base members in a first direction and said second set of spring-loaded arm members extending from said base members in a second and opposite direction;
- an orbiting applicator assembly comprising a compression roller, said orbiting applicator assembly pivotally mounted to said first set of spring-loaded arm members such that said orbiting applicator assembly is outwardly biased;
- an orbiting centering assembly, said orbiting centering assembly pivotally mounted to said second set of spring-loaded arm members such that said orbiting centering assembly is outwardly biased;
- said orbiting applicator assembly and orbiting centering assembly being positioned on opposite sides of said rotatable shaft;
- wherein the combination of said first set of spring-loaded arm members, said base members and said second set of spring-loaded arm members presents a Z-shaped configuration;
- a spool retaining a length of heat-curable filament;
- wherein said filament is passed onto said compression roller for application to the inner wall of a pipe or pipe liner.
