Abstract
Abstract A filament is disposed in a liquidtight container wrapped about a spool which is free to rotate therein, the filament passing through a dispensing nozzle fixed in the side of the container, the dispensing nozzle having an outward-facing conical block of deformable plastic containing a filament passage and the dispensing nozzle also having a pressure plug turned inward about the conical block compressing it about a filament passing therethrough.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
A filament dispenser for use with a rod-wrapping machine having a sector gear on which said filament dispenser is mounted, said sector gear moving said filament dispenser about a rod to be wrapped, said filament dispenser comprising, in combination, a fluidtight container containing an aperture, a spool rotatably disposed within said container having filament wound thereon, and a filament-dispensing nozzle on said container disposed about said aperture, said nozzle having a compression block of deformable plastic disposed over said aperture in said container, said block containing a longitudinal passage larger than said filament extending therethrough, and a pressure plug containing a longitudinal passage aligned with the passage in said block accommodating said filament, said plug being adapted to be screwed inward against said block compressing said block and said passage therein about said filament.
Claim 2
Dependent Claim
134 words
A filament dispenser for use with a rod-wrapping machine having a sector gear on which said filament dispenser is mounted, said sector gear moving said filament dispenser about a rod to be wrapped, said filament dispenser comprising, in combination, a fluidtight container containing an aperture, a spool rotatably disposed within said container having filament wound thereon, and a filament-dispensing nozzle on said container disposed about said aperture, said nozzle having a compression block of deformable plastic disposed over said aperture in said container, said block containing a longitudinal passage larger than said filament extending therethrough, and a pressure plug containing a longitudinal passage aligned with the passage in said block accommodating said filament, said plug being adapted to be screwed inward against said block compressing said block and said passage therein about said filament.
Claim 3
Dependent Claim
33 words
The combination according to claim 1 wherein said compression block has an outward-facing conical portion and said pressure plug contains an inward-facing conical portion receiving said outward-facing conical portion of said block therein.
Claim 4
Dependent Claim
31 words
The combination according to claim 2 wherein said block has a rear shank extending into said aperture in said container, said conical portion of said block being larger than said aperture.
Claim 5
Dependent Claim
