Abstract
Abstract The flexible element for processing fibers is constituted by a tubular flexible member which is flattened in such a manner that its cross-section has a shape which is close to that of a figure eight and consequently determines two hollow lobes, one of which is the fiber-processing lobe while the other is a fastening lobe which is inserted through a longitudinal mounting slot in a supporting tube and maintained applied against the internal wall of the said tube by a locking rod placed in the bottom of the said fastening lobe, the width of the longitudinal slot of the supporting tube being smaller than the external diameter of the fastening lobe fitted with its locking rod.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
A device for operating upon fibers, comprising: a tubular flexible member which is flattened so as to have a cross-sectional shape similar to a figure eight and form two hollow lobes one of which is a fiber-operating lobe while the other is a fastening lobe, a supporting tube having a longitudinal mounting slot, said fastening lobe being inserted through said longitudinal mounting slot into said supporting tube, a locking rod placed in said fastening lobe for holding the fastening lobe inside said tube, the width of said longitudinal slot in said supporting tube being smaller than the external diameter of said fastening lobe fitted with the locking rod, said tube having two extremities, each extremity of said supporting tube having two diametrically opposite longitudinal fastening slots, a pair of retaining tongues substantially equal in width to the external diameter of said tube and extending into the slots for retaining said tube, and a pair of sliding sleeves fitted over said extremities of said supporting tube and embracing said tongues.
Claim 2
Independent Claim
169 words
A device for operating upon fibers, comprising: a tubular flexible member which is flattened so as to have a cross-sectional shape similar to a figure eight and form two hollow lobes one of which is a fiber-operating lobe while the other is a fastening lobe, a supporting tube having a longitudinal mounting slot, said fastening lobe being inserted through said longitudinal mounting slot into said supporting tube, a locking rod placed in said fastening lobe for holding the fastening lobe inside said tube, the width of said longitudinal slot in said supporting tube being smaller than the external diameter of said fastening lobe fitted with the locking rod, said tube having two extremities, each extremity of said supporting tube having two diametrically opposite longitudinal fastening slots, a pair of retaining tongues substantially equal in width to the external diameter of said tube and extending into the slots for retaining said tube, and a pair of sliding sleeves fitted over said extremities of said supporting tube and embracing said tongues.
Claim 3
Dependent Claim
40 words
A device as in claim 1, wherein said longitudinal mounting slot extends over the entire length of said supporting tube and wherein one of said longitudinal fastening slots is constituted by the corresponding end portion of said longitudinal mounting slot.
Claim 4
Dependent Claim
30 words
A device as in claim 1, wherein said sliding sleeve is constituted by a tube segment which is split lengthwise and adapted to grip said supporting tube radially and elastically.
Claim 5
Dependent Claim
27 words
A device as in claim 1, wherein each said retaining tongue has a centering extension substantially equal in width to the internal diameter of said supporting tube.
Claim 6
Dependent Claim
27 words
A device as in claim 1, wherein each said retaining tongue is provided with an axial abutment for positioning the corresponding end face of said supporting tube.
Claim 7
Dependent Claim
42 words
A device as in claim 1, further comprising a pair of driving members, said retaining tongues being respectively rigidly fixed to said driving members for displacing said supporting tube in a direction at right angles to the general direction of said tube.
Claim 8
Dependent Claim
19 words
A device as in claim 6, wherein each of said driving members forms a link of an endless chain.
Claim 9
Independent Claim
226 words
An apparatus for operating on fibers comprising a textile fiber-modifying assembly, said assembly comprising a flexible fiber-modifying element constituted by a tubular flexible member which is flattened so as to have a cross-sectional shape similar to a figure eight and forming two hollow lobes one of which is a fiber-modifying lobe and the other of which is a fastening lobe, a supporting tube having a longitudinal mounting slot, said fastening lobe of said tubular flexible member inserted through said longitudinal mounting slot into said supporting tube, and a locking rod placed in the bottom of said fastening lobe for maintaining said fastening lobe applied against the internal wall of said tube, a fastening assembly for supporting each end portion of said supporting tube, said fastening assembly comprising a support member, a rigid retaining tongue secured to said support member, said tongue having a width equal to the outer diameter of said supporting tube, each end portion of said supporting tube having two diametrically opposed fastening slots, said tongue engaged within the opposed fastening slots of one end portion of said fastening tube, a sleeve slidably fitted over said end portion of said supporting tube and embracing the edge portions of said tongue positioned within said fastening slots, and an axial abutment member on said support member for positioning one said end portion of said supporting tube.
Claim 10
Independent Claim
226 words
An apparatus for operating on fibers comprising a textile fiber-modifying assembly, said assembly comprising a flexible fiber-modifying element constituted by a tubular flexible member which is flattened so as to have a cross-sectional shape similar to a figure eight and forming two hollow lobes one of which is a fiber-modifying lobe and the other of which is a fastening lobe, a supporting tube having a longitudinal mounting slot, said fastening lobe of said tubular flexible member inserted through said longitudinal mounting slot into said supporting tube, and a locking rod placed in the bottom of said fastening lobe for maintaining said fastening lobe applied against the internal wall of said tube, a fastening assembly for supporting each end portion of said supporting tube, said fastening assembly comprising a support member, a rigid retaining tongue secured to said support member, said tongue having a width equal to the outer diameter of said supporting tube, each end portion of said supporting tube having two diametrically opposed fastening slots, said tongue engaged within the opposed fastening slots of one end portion of said fastening tube, a sleeve slidably fitted over said end portion of said supporting tube and embracing the edge portions of said tongue positioned within said fastening slots, and an axial abutment member on said support member for positioning one said end portion of said supporting tube.
Claim 11
Dependent Claim
30 words
A device as In claim 8, wherein said sleeve is formed by a tube segment which is split lengthwise and is arranged to grip said supporting tube radially and elastically.
Claim 12
Dependent Claim
54 words
A device, as set forth in claim 8, wherein said longitudinal mounting slot extends for the entire length of said supporting tube and said fastening slots extend in the longitudinal direction of said mounting slot and one of said fastening slots at each end forms a corresponding end portion of said longitudinal mounting slot.
Claim 13
Dependent Claim
52 words
A device as in claim 8, wherein said retaining tongue has a centering extension substantially equal in width to the internal diameter of said supporting tube and said centering extension extends inwardly into the internal diameter of said supporting tube from the portion of said retaining tongue positioned within said fastening slots.
Claim 14
Dependent Claim
55 words
A device as in claim 8, wherein said support member comprises a driving member, said retaining tongue rigidly fixed to said driving member and one said driving member secured to each end of said supporting tube for displacing said supporting tube in a direction at right angles to the longitudinal direction of said supporting tube.
Claim 15
Dependent Claim
19 words
A device as in claim 12, wherein each of said driving members forms a link of an endless chain.
