Abstract
Abstract A filament feeding device in which filament from a supply thereof is tangentially wound about a storage drum from which said filament is axially withdrawn. A housing which is fixed has a cavity within which the storage drum is removably seated. The outer contour of the drum and the confronting inner contour of the cavity are matingly shaped so as to define a radial gap therebetween and also so as to prevent significant relative rotation between the drum and the housing whereby the drum is in effect floating within the housing, being unsecured thereto. The filament tangentially wound about the drum forms a plurality of windings which advance axially within the radial gap and is thereafter withdrawn axially through an aperture at the opposite end of the housing. The mating confronting contours of drum and housing may be oval shaped, polygonically shaped, or be shaped in any other non-circular contour which results in preventing relative rotation between the drum and the housing.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
119 words
A filament feeding device comprising, a. a drum, b. support means for said drum, c. said support means comprising a housing fixed to a frame member and being open ended at one end thereof to define a cavity within which said drum is removably supported, d. the outer contour of said drum and the confronting inner contour of said cavity being matingly shaped so as to define a radial gap therebetween and prevent significant relative rotation between said drum and said support means; and e. means for winding said filament about said drum adjacent one end thereof for forming on said drum a plurality of windings which advance toward the other end of said drum within said radial gap.
Claim 2
Dependent Claim
119 words
A filament feeding device comprising, a. a drum, b. support means for said drum, c. said support means comprising a housing fixed to a frame member and being open ended at one end thereof to define a cavity within which said drum is removably supported, d. the outer contour of said drum and the confronting inner contour of said cavity being matingly shaped so as to define a radial gap therebetween and prevent significant relative rotation between said drum and said support means; and e. means for winding said filament about said drum adjacent one end thereof for forming on said drum a plurality of windings which advance toward the other end of said drum within said radial gap.
Claim 3
Dependent Claim
40 words
A filament feeding device in accordance with claim 1, wherein said support means is provided with an aperture opposite said one end thereof through which the filament wound about said drum travels as it is withdrawn axially of the drum.
Claim 4
Dependent Claim
54 words
A filament feeding device in accordance with claim 2, wherein a peripheral edge is defined at said one end of said housing about said cavity and said drum is provided with a peripheral flange at one end thereof whereby said peripheral edge supportingly engages said peripheral flange for supporting said drum within said cavity.
Claim 5
Dependent Claim
36 words
