摘要:
A yarn producing apparatus produces CNT (carbon nanotube) yarn from CNT fibers while causing the CNT fibers to run. The yarn producing apparatus includes an aggregating unit that aggregates the CNT fibers, and a twisting and winding device that twists the CNT fibers aggregated by the aggregating unit. The aggregating unit includes an adjusting mechanism that adjusts the aggregation state of the CNT fibers.

Methods and systems are provided to wrap a faired tether around a drum. The tether may be connected to an aerial vehicle. The method may involve guiding a faired tether around an exterior surface of a drum, wherein the drum comprises a helical shaped step around the exterior surface that is configured to mate with at least part of the faired tether, and to stack subsequent layers of wrapped tether in a staggered manner along the longitudinal axis of the drum. The faired tether may be guided onto the step using one or more level winds.

A long fiber reinforced plastic strand production device is provided with: a rotary type haul-off machine which forms a long fiber reinforced plastic strand by drawing out a reinforcing fiber bundle which has been impregnated with a plastic from an impregnation head while rotating the reinforcing fiber bundle around the axis thereof to apply twists in the reinforcing fiber bundle, and draws in the formed long fiber reinforced plastic strand; and a rotary type winding-up machine which introduces the long fiber reinforced plastic strand drawn from the rotary type haul-off machine to a winding bobbin while rotating the long fiber reinforced plastic strand around the axis of the strand in the same direction as the rotation direction of the reinforcing fiber bundle rotated by the rotary type haul-off machine, and winds the rotated long fiber reinforced plastic strand around the winding bobbin. The rotary type winding-up machine is constituted to be capable of rotating the long fiber reinforced plastic strand at a number of rotation smaller than the number of rotation of the reinforcing fiber bundle by the rotary type haul-off machine.

The invention relates to a device for coiling a thread or wire-type object (1) onto a winding jig (10) by means of a flyer (7) circling the winding jig (10). The object (1) is guided to the flyer (7) by a tube (2) and the flyer (7) is positioned on the tube (2) in rotating manner. Said winding jig (10) is coupled to a carrier sleeve (18) which is arranged approximately in the direction of the longitudinal axis (A) of the tube (2), at a distance (A) from the same, in order to pass the object (1). Said carrier sleeve (18) is associated with the fixed tube (2) in a fixed manner.

A sawing device comprises a layer of parallel wires (8) which move with reciprocal or continuous movement whilst bearing against a member (9) to be sawed fixed to a support table (10). The wire comes from a management region (41a) of the wire, constituted by two spools of wire, one (2a) a payout spool and the other (14a) a take-up spool, which do not rotate, but which have a revolving spooling and unspooling member (42) about the spools permitting rendering the sawing device independent of the mass of the spools of wire (2a, 14a) and hence of the length of the wire.

A process for winding a fiber strand about a bobbin to form a wound package includes: (a) winding a fiber strand about a portion of a bobbin supported upon a rotatable collector of a winder to form a primary layer of a wound package. The primary layer has an overall length, an upper portion and a lower portion. Each of the upper portion and lower portion have a length which is less than the overall length. The primary layer has a plurality of sublayers, each of the plurality of sublayers having a plurality of layers. Each of the plurality of layers of the sublayers is successively wound upon a preceding layer and has a length which is less than the preceding layer. Each of the plurality of layers of the sublayers has an outer layer having a length which corresponds generally to the length of the lower portion, such that the primary layer is formed. A secondary layer is formed thereon which includes a plurality of layers upon the primary layer. Each of the plurality of layers is successively wound upon a preceding layer and has a length which is less than the preceding layer. The length of each of the plurality of layers has a midpoint which corresponds to a midpoint of the overall length of the primary layer, such that a wound package is formed.
