Abstract

The present invention provides a steam system for repairing bent carpet fibres and includes a steam generator and an application tool having a head with a downwardly opening oven-like steam chamber fed by the steam generator to apply steam to the bent carpet fibres at a pressure and temperature to cause fibre relaxation. The head of the application tool further includes a fibre lifter for lifting the fibres to an upstanding position after they have been relaxed by the steam.

Claims

1. A steam system for repairing bent carpet fibres, said steam system comprising a steam generator and an application tool having a head with a steam chamber fed by said steam generator, said steam chamber being defined by a downwardly opening shroud supporting said tool and trapping the steam at the carpet fibres immediately beneath said shroud to provide an oven-like effect for resetting of the carpet fibres from a bent to an unbent position, said head of said application tool further including fibre lifting means for lifting the fibres to the unbent position after having been relaxed by the steam.

2. A steam system as claimed in claim 1, wherein said steam generator comprises a plurality of individual steam units feeding a common supply tube to said head of said application tool.

3. A steam system as claimed in claim 2, wherein said individual steam units are provided with separate immersion heaters, each of said immersion heaters being provided with its own on/off control and indicator means for indicating on/off operation of said immersion heaters.

4. A steam system as claimed in claim 2, including a water height sighting tube at each of said individual steam units.

5. A steam system as claimed in claim 1, including a steam supply tube form said steam generator to said application tool, said steam supply tube comprising an inner core and an outer insulating cover over said inner core.

6. A steam system as claimed in claim 5, wherein said outer insulating cover comprises a flexible corrugated cover.

7. A steam system as claimed in claim 1, wherein said head of said application tool includes a steam bar extending widthwise thereof, said steam bar being provided with a plurality of steam holes therealong.

8. A steam system as claimed in claim 7, wherein said fibre lifting means comprises a stiff bristled brush separated from said steam tube in said head of said application tool.

9. A steam system as claimed in claim 8, wherein said downwardly directed shroud includes non-heat conductive sides skirts extending between said metallic forward and rearward edge portions.

10. A steam system as claimed in claim 7, said shroud comprising metallic forward and rearward edge portions with at least said rearward edge portion forming a scraper for said head of said application tool.

11. A steam system for repairing bent carpet fibres, said steam system comprising a steam generator and an application tool having a head with a steam chamber fed by said steam generator, said steam chamber being defined by a downwardly opening shroud supporting said tool and trapping the steam at the carpet fibres immediately beneath said shroud to provide an oven-like effect for resetting of the carpet fibres from a bent to an unbent position, said head of said application tool further including fibre lifting means for lifting the fibres to the unbent position after having been relaxed by the steam, said application tool being connected to said steam generator by a steam supply hose, said supply hose being insulated to maintain high temperature of the steam passing through said hose with an external hose temperature below that to cause resetting of any carpet fibres on which said hose is laid.

12. A steam system as claimed in claim 11, wherein said hose comprises an inner core and an outer corrugated insulating cover over said inner core.
