Disclosed is a method for producing an optical fiber coil including the following steps: a. symmetrical winding of an optical fiber around a shaft, the winding forming a pattern including a same number N of layers of each half of the optical fiber, one layer including a set of turns of optical fiber and spaces between adjacent turns, the winding forming a sectored arrangement including a regular stacking area including at least one continuous sealing surface between two layers of adjacent turns, and an overlap area where portions of optical fiber linking different turns cross each other; b. infiltration of a glue through an external surface of the overlap area in such a way that the glue infiltrates into the spaces located between adjacent turns in the regular stacking area.

While a winding member is making one rotation, an optical fiber is once skewed relative to the circumferential direction and further shifted by a desired length in the width direction of a circumferential surface. In this state, the winding member winds up the optical fiber. This operation is performed in the same direction every rotation when the winding member rotates (N−1) times. Next, in the N-th rotation of the winding member, a guide member performs the guide to the optical fiber to skew reversely to the direction of shifting in the (N−1) rotations of the winding member.

A plurality of relatively long wires having the same diameter are bundled together to obtain a bundle wire in a continuous wire bundling process. A wire bundling device includes a plurality of reels rotated by a rotating drive and wind a wire while a first end is engaged. A wire second-end pressing device collects and presses a second end of each of a plurality of wires having a predetermined length which is fed from a single spool and individually wound around each of a plurality of reels. The wires are withdrawn in a collected state from the reels by a withdrawing device between the plurality of reels and the wire second-end pressing device. The wire second-end press includes first and second pressing devices. The reels are rotated by an electric motor with a contact roller that rotates in contact with an outer circumference of the reel. The motor can be moved so that the contact roller selectively makes contact with the outer circumferences of the reels.

A winding device for winding up at least one material to be wound onto at least one exchangeable tube, having at least one winding mandrel which, in at least one operating state, is provided to receive the at least one tube and/or drive it in rotation about a winding axis, comprising at least one mass-determining unit which is provided to determine, in at least one instant of time during at least one winding-up operation, at least one mass characteristic of the at least one tube and/or of the at least one material to be wound that has been wound up in this instant on the at least one tube.

A method for handling a fiber reinforced tube the tubular wall of which has a stiffness which allows the tube to maintain a nominal circular cross section of its own, the tube including a liner, a fiber reinforcement surrounding the liner and a coating surrounding the fiber reinforcement, includes the steps of: flattening the tube so as to obtain a non-circular shape, such as an oval or elliptical shape, subsequently winding the flattened tube onto a reel. Thanks to the method, a combination of a wound flattened tube and a reel is obtained which is fit for road transport.

A filament winding method performs a hoop winding step including a first step of fixing an end of a fiber bundle to a liner surface at a starting position of hoop winding, a second step of hoop winding the fiber bundle having the end fixed to the liner surface in the first step, a third step of fixing the fiber bundle hoop wound in the second step to the liner surface at an ending position of hoop winding, and a fourth step of cutting the fiber bundle upstream in a fiber bundle supplying direction of the position where the fiber bundle is fixed in the third step.

A system and method for coiling and sealing an elongate, flexible component includes a coiler and a sealer positioned beneath the coiler. The coiler includes a rotatable central core and a feeding tube for guiding and transferring a free end of the flexible component onto the central core to form a coil. The coil is then dropped in a generally vertical downward direction from the coiler into a partially-sealed and partially-opened container positioned beneath the coiler and disposed within the sealer. The sealer seals the remaining one or more open sides of the container and then drops the coil encased within the sealed container in a generally vertical downward direction onto a conveyor. The container may be made of a heat-shrinkable material and the conveyor may transport the sealed container into a heat-shrink oven to heat shrink the container around the coil.

A flexible tubing for fine bubble aeration is provided with an air passageway defined in part by an upper portion and a lower portion. The tubing can be made of a uniform weighted material with more material in the lower portion than in the upper portion. This makes the tubing self-orienting, in that it will tend to orient itself with micro-slits along the upper portion facing upward and the lower portion facing downward when submerged in a body of water. An automated, one-stage production line converts raw tubing material to a finished tubing product without the need for separate processing. A method of coiling the tubing places the micro-slits approximately 90° away from the surface of a spool hub, thereby avoiding a longitudinal arch in the tubing and ultimately preventing roll-over and improper slit orientation after installation in a water body.

A system and process for winding and mechanically transporting a wound package includes: (a) a plurality of fibers; (b) a guide for gathering the fibers to form a bundle; (c) a winder having a rotatable package collector and an apparatus for rotating the package collector about a stationary generally vertical axis; and (d) a mechanical transport for receiving the wound package from the package collector and transporting the wound package from a first position to a second position horizontally spaced apart from the first position.
