Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
111 words
A device for the winding of threads or filaments with speedregulated, motor driven winding heads which are arranged in at least two decks, one below the other, and to which the thread feed takes place from above, dancer arms serving as measuring sensors for the speed regulation of the winding motors and being mounted above the winding head decks, the thread or filament path to respective winding heads including a thread loop path over respective dancer arms, and said dancer arms being arranged in pairs one above the other in respective positions whereby the lower dancer arm is situated between the thread or filament path loop across the upper dancer arm.
Claim 2
Independent Claim
111 words
A device for the winding of threads or filaments with speedregulated, motor driven winding heads which are arranged in at least two decks, one below the other, and to which the thread feed takes place from above, dancer arms serving as measuring sensors for the speed regulation of the winding motors and being mounted above the winding head decks, the thread or filament path to respective winding heads including a thread loop path over respective dancer arms, and said dancer arms being arranged in pairs one above the other in respective positions whereby the lower dancer arm is situated between the thread or filament path loop across the upper dancer arm.
Claim 3
Dependent Claim
47 words
A device as claimed in claim 1 wherein said dancer arms have pins or rollers over which the respective threads or filaments run, and means pivotally supporting said dancer arms to provide arcuate movement of pins or rollers of said dancer arms in substantially the same plane.
Claim 4
Dependent Claim
58 words
A device as claimed in claim 1, and adapted for separate winding of at least two threads or filaments on a common winding member, said device characterized by at least one dancer arm having a plurality of rollers or pins corresponding in number to the number of said separate windings and said rollers or pins being axially aligned.
Claim 5
Dependent Claim
22 words
A device as claimed in claim 3 whereby said dancer arm has a plurality of rollers rotatably journaled on a common axle.
