Yarn delivery device for a twisting or cabling machine
Yarn delivery device for a twisting or cabling machine having a first deflection roller for deflecting a yarn; a driven godet, arranged downstream of first deflection roller in yarn transport direction; a separator roller, arranged relative to the godet such that a yarn can be laid several times around the separator roller and the godet, said yarn being wrapped around separator roller and godet jointly; and a pitch lever, having a second deflection roller arranged downstream of godet in the yarn transport direction, for deflecting the yarn again. A cantilever, having a third deflection roller, which, in the yarn transport direction, is arranged downstream of second deflection roller and upstream of traversing yarn guide for feeding the yarn onto a take-up package, second deflection roller being arranged on a different side of a vertical plane extending through axis of rotation of the separator roller from the third deflection.
YARN DELIVERY DEVICE FOR A TWISTING OR CABLING MACHINE
Yarn delivery device for a twisting or cabling machine, for feeding a yarn via a traversing yarn guide to a take-up package, the yarn delivery device having a first deflection roller for deflecting a yarn; a driven godet, arranged downstream of first deflection roller in yarn transport direction; a separator roller, arranged relative to the godet such that a yarn can be laid several times around the separator roller and the godet, said yarn being wrapped around separator roller and godet jointly; and a pitch lever, having a second deflection roller arranged downstream of godet in the yarn transport direction, for deflecting the yarn again. A cantilever, having a third deflection roller, which, in the yarn transport direction, is arranged downstream of the second deflection roller and upstream of traversing yarn guide for feeding the yarn onto a take-up package, the second deflection roller being arranged on a different side of a vertical plane extending through axis of rotation of the separator roller from the third deflection roller to receive the yarn from separator roller or godet and to deflect the yarn toward third deflection roller.
Outer-yarn brake, a cording or cabling machine with an outer-yarn brake and a method for operating such a cording or cabling machine
An outer-yarn brake (14) for a cording or cabling machine with at least one workstation comprising a bobbin rack (2) for holding at least one feed bobbin (4), a spindle (12) for the rotation of a yarn (6) withdrawn from the feed bobbin (4) around a bobbin pot associated with the spindle (12), and a yarn-guide channel (10) for guiding the yarn (6) received via a free end-portion (8) of the yarn-guide channel (10) to the spindle (12). The outer-yarn brake (14) can be arranged in the yarn running direction of the withdrawn yarn (6) between the feed bobbin (4) and the yarn-guide channel (10) to guide through the withdrawn yarn (6) and comprises a clamping portion for defined braking of the running yarn (6). The outer-yarn brake (14) can be coupled to the free end-portion (8) in order to form a yarn input for the yarn-guide channel (10).
Method for operating a spindle of a two-for-one twisting or cabling machine and associated two-for-one twisting or cabling machine
A method for operating a spindle (2) of a two-for-one twisting or cabling machine, in which an outer yarn (5) is drawn off a first feed package (7) and the spindle (2) rotates in a yarn balloon (B), wherein the spindle (2) comprises a device (6) for influencing the balloon yarn tension of an outer yarn (5), which is connected to a control circuit (18), and has a spindle pot (19) for receiving a second feed package (15), a yarn deflection device (20), a balancing system (9) for forming a twisting or cabling point as well as a spooling and winding device (12). The drive of the yarn balloon (B) is performed via a fixed throw-off point (21) on the yarn deflection device (20).
OUTER-YARN BRAKE, A CORDING OR CABLING MACHINE WITH AN OUTER-YARN BRAKE AND A METHOD FOR OPERATING SUCH A CORDING OR CABLING MACHINE
An outer-yarn brake (14) for a cording or cabling machine with at least one workstation comprising a bobbin rack (2) for holding at least one feed bobbin (4), a spindle (12) for the rotation of a yarn (6) withdrawn from the feed bobbin (4) around a bobbin pot associated with the spindle (12), and a yarn-guide channel (10) for guiding the yarn (6) received via a free end-portion (8) of the yarn-guide channel (10) to the spindle (12). The outer-yarn brake (14) can be arranged in the yarn running direction of the withdrawn yarn (6) between the feed bobbin (4) and the yarn-guide channel (10) to guide through the withdrawn yarn (6) and comprises a clamping portion for defined braking of the running yarn (6). The outer-yarn brake (14) can be coupled to the free end-portion (8) in order to form a yarn input for the yarn-guide channel (10).
