A winding device provided with an inlet for drawing a string-shaped winding target member and configured to wind the winding target member includes: a drum having flanges at both end portions of a body in an axial direction thereof and provided rotatably about the an axis of the body,; a drive source configured to rotate the drum, a first guide portion configured to draw the winding target member along a first axis arranged substantially perpendicularly to the axis of the body in a skew relationship, a swing member provided swingably about the first axis, and a second guide portion attached to a tip end of the swing member to guide the winding target member from the first guide portion to the drum.

The invention relates to a winding device (100) for winding a fibre coil, comprising a coil carrier (110) for wrapping with fibre (210) in order to produce a coil body (220) made of wound fibres (210), a fibre supply (120) for supplying a fibre (210) for wrapping the coil carrier (110), and an adhesive device (130) for producing droplets of adhesive (140) for bonding the outermost layer of fibres (210) on the coil body (220) to fibres (210) freshly laid onto the coil body (220).

A flyer assembly including a spindle rotatable about an axis of rotation, an arm coupled to the spindle, a level wind device axially mounted to the arm, a first friction member disposed along a width of the level wind device and shaped into a convex curve defining the width of the level wind device, a second friction member offset from the first friction member, and a fulcrum having an eye or hook.

A method for implementing a correct winding of a wire on a spool. The method is characterized in that it comprises a step for calculating the angular speed of a motor displacing a wire dispensing device according to the wire winding pitch and according to the pulling error, detected in relation to a given pre-set set-point and to a tolerance value, in order to determine the presence of a possible “valley error”, or of a possible “peak error”. Furthermore, if during the spool winding a “valley error” or a “peak error” is detected, the control device decides whether to slow down or to increase the speed of the wire dispensing device with the aim of filling the valley or of skipping the peak.

A crystal growing system includes a rotating seed lift assembly to rotate and lift a seed crystal supported by a cable. The seed lift assembly includes a spool that rotates to wrap the cable around the spool, thus raising the cable. As the spool rotates, it moves in an axial direction to avoid displacing the cable in the axial direction. A leadscrew in a counterweight assembly is mechanically coupled to the spool via a coupling (e.g., a sprocket-and-chain coupling coupled to the spool spindle). As the spool rotates, the leadscrew thus rotates at a rate proportional to the spool's rate of rotation. A movable counterweight driven by the leadscrew is thus driven to move in a direction opposite the axial direction (e.g., opposite the movement of the spool). The counterweight assembly is thus configured to offset center-of-mass changes that would have otherwise been introduced by movement of the spool.

The present disclosure relates to a collection device and a preparation system, including a pre-adjustment mechanism which is disposed in a housing and configured to adjust at least one bundle of carbon nanotube aggregates, and includes a first pre-adjustment sub-mechanism and a second pre-adjustment sub-mechanism for adjusting carbon nanotube aggregations along a first direction and a second direction, respectively; a winding mechanism for winding and collecting the carbon nanotube aggregates passing through the pre-adjustment mechanism.

An automatic cable spooling device is provided, comprising a frame adapted to rotatably hold a spooling drum; a drum motor operatively connected to the drum; and a levelwind arm positioned adjacent to the drum. The levelwind arm is movable in a plane aligned with the rotational axis of the drum. The system further includes an arm motor operatively connected to the levelwind arm; and a microcontroller in communication with the arm motor. An arm encoder is adapted to sense a position of the arm motor and is in communication with the microcontroller. Likewise, a drum encoder is adapted to sense a position of the drum motor and is also in communication with the microcontroller. The position of the levelwind arm is controlled by the microcontroller based on the position of the drum, the spooling width, and a predetermined cable diameter.
