Definitions
- Present invention is an improved version of a twisting machine disclosed in WO2005040465 and relates to a machine based on a magnetic coupling and capable of independently controlling twisting speed of a single or plurality of yarn(s) and winding speed of twisted yarns onto a bobbin and method of the same, the machine of the invention can also be used for yarn braking.

Threading of yarns from untwisted bobbins to the machine of US 3,406,511 is difficult, and moreover an outer container is required to prevent from hitting the yarn balloon to the magnets.
- US 3,368,336 discloses a machine which is driven directly of the machine of US US 3,406,511.
- it is needed a considerable space between the rotor and the stator for enabling the yams to pass smoothly, which gives rise to a certain inefficiency in transmitting motion to bobbin winding unit.
- the bobbin carrier of US 3,834,146 is held stationary via radial magnets. Furthermore, yarn-twisting speed is dependent to winding speed of twisted yarns onto bobbin as bobbin winding unit is driven from twisting shaft.
- twisting machines With the known twisting machines, higher machine speeds cannot be not achieved due to extremely high centrifugal forces occurred as radially placed magnets around the carrier. Furthermore, in most twisting machines, yam twisting speed is not independent from the winding speed of the twisted yarn onto bobbin.
- the magnetic coupling according to the invention can provide a yam brake for two-for- one twisting machines in particular.
- One object of the present invention is to increase yarn twisting efficiency by independently controlling the twisting speed and the winding speed of the twisted yarns onto bobbin by use of a machine being relatively light in weight and simple in design.
- Another object of the present invention is to reduce centrifugal effects, so providing twisting at higher speeds and prevent the yarn balloon from tangling to an external component by transmitting the motion of the main shaft to an upper level in axial direction through a magnetic coupling and/or holding the bobbin carrier stationary through a magnetic coupling.
- a twisting machine having a main shaft to which a yarn or a plurality of yarns is/are introduced in use and from which the yarns or the plurality of yarns is/are taken out in use, and the main shaft being driven by a drive element; a twisting disc being associated with the main shaft and being in contact with the yarn or plurality of yarns taken out of the shaft while rotating in use; a winding unit driven by another drive element for winding yarn or yarns passed through a yarn guide onto a bobbin, the yarn or yarns forming a yarn balloon contacting the twisting disc; and a stationary carrier holding the bobbin, characterized in that an axial magnetic coupling is provided in the shaft axis direction for holding the carrier stationary.
- the invention further comprises a method for holding the carrier stationary via an axial magnetic coupling according to the twisting machine of the invention.
- holding the carrier stationary via magnetic coupling is achieved through magnets connected to the body of the machine, these magnets being provided underside a disc such that the magnets circularly disposed around the axis of the shaft and corresponding magnets oppositely poled with the above mentioned magnets are provided upper side of the disc such that the magnets circularly disposed around the axis of the shaft.
- driving force to the yarn winding unit provided from another motor is transmitted to the upper level of the disc and the carrier by an axial magnetic coupling in the shaft axis direction.
- a number of magnets being associated with the other motor are disposed underside of the disc in a circular arrangement, and a number of corresponding magnets oppositely poled with the above mentioned magnets are disposed upper side of the disc.
- the magnets at the upper side are associated with the bobbin winding unit. Therefore, drive force provided by the other motor is transmitted magnetically in axial direction through magnets oppositely poled and disposed circularly around shaft axis and therefore bobbin winding unit can be driven.
- the invention further comprises a method for driving the bobbin unit via an axial magnetic coupling according to the twisting machine of the invention.
- twisting machine which is more compact, having entire driving mechanisms inside the yarn balloon, not having an external component outside of the yarn balloon, being independently controllable of twisting speed and the winding speed, and being capable of operating relatively high speeds and being cost effective is provided.
