Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
In a textile machine having at least one work station, an apparatus for holding ready and positioning yarn packages to be unwound at the work station, the apparatus comprising rotatable shaft means, a plurality of arm means radially extending from said shaft means and circumferentially disposed at a given angle from one another, horizontally extending pivot means mounted on each of said arm means, a spool holder radially extending from each of said pivot means, said spool holder and said pivot means together with said plurality of arm means on which said pivot means are mounted, forming a positioning device, the plurality of spool holders at the work station being jointly revolvable with the plurality of arm means about said shaft means.
Claim 2
Dependent Claim
122 words
In a textile machine having at least one work station, an apparatus for holding ready and positioning yarn packages to be unwound at the work station, the apparatus comprising rotatable shaft means, a plurality of arm means radially extending from said shaft means and circumferentially disposed at a given angle from one another, horizontally extending pivot means mounted on each of said arm means, a spool holder radially extending from each of said pivot means, said spool holder and said pivot means together with said plurality of arm means on which said pivot means are mounted, forming a positioning device, the plurality of spool holders at the work station being jointly revolvable with the plurality of arm means about said shaft means.
Claim 3
Dependent Claim
16 words
Apparatus according to claim 1 including a yarn-guiding member connected to each of said arm means.
Claim 4
Dependent Claim
12 words
Apparatus according to claim 2 wherein said yarn-guiding members are pivotally mounted.
Claim 5
Dependent Claim
59 words
Apparatus according to claim 2 wherein each of said pivot means area hollow, and further comprises a pivot shaft rotatably disposed within each of said hollow pivot means, said spool holders and said yarn-guiding members being secured, respectively, to said hollow pivot means and said pivot shafts and being movable relative to one another as said positioning device turns.
Claim 6
Dependent Claim
20 words
An apparatus according to claim 1 further including manual means for producing a stepwise turning motion of said positioning device.
Claim 7
Dependent Claim
38 words
Apparatus according to claim 1 including drive means for turning said positioning device through an angle corresponding to the given angle at which said plurality of arm means are disposed circumferentially from one another about said shaft means.
Claim 8
Dependent Claim
24 words
Apparatus according to claim 6 wherein said drive means is couplable with the respective work station for producing said turning of said positioning device.
Claim 9
Dependent Claim
176 words
In a textile machine having a plurality of work stations, an apparatus located at each of the work stations for holding ready and positioning yarn packages to be unwound at the respective work stations, each apparatus comprising rotatable shaft means, a plurality of arm means radially extending from said shaft means, and circumferentially disposed at a given angle from one another, horizontally extending pivot means mounted on each of said arm means, a spool holder radially extending from each of said pivot means, said spool holder and said pivot means together with said plurality of arm means on which said pivot means are mounted, forming a positioning device, the plurality of spool holders at each of the work stations being jointly revolvable with the respective plurality of arm means about the respective shaft means, and drive means at each of the work stations for turning the respective positioning device through an angle corresponding to the given angle at which the respective plurality of arm means are disposed circumferentially from one another about the respective shaft means.
Claim 10
Dependent Claim
176 words
In a textile machine having a plurality of work stations, an apparatus located at each of the work stations for holding ready and positioning yarn packages to be unwound at the respective work stations, each apparatus comprising rotatable shaft means, a plurality of arm means radially extending from said shaft means, and circumferentially disposed at a given angle from one another, horizontally extending pivot means mounted on each of said arm means, a spool holder radially extending from each of said pivot means, said spool holder and said pivot means together with said plurality of arm means on which said pivot means are mounted, forming a positioning device, the plurality of spool holders at each of the work stations being jointly revolvable with the respective plurality of arm means about the respective shaft means, and drive means at each of the work stations for turning the respective positioning device through an angle corresponding to the given angle at which the respective plurality of arm means are disposed circumferentially from one another about the respective shaft means.
