The present disclosure is directed to a reusable yarn carrier tube around which yarn may be wound at high speeds (e.g., within winding machines). The yarn carrier tube may include a pick-up groove having structural features configured to better snag yarn to initiate winding of the yarn around the cylindrical body of the yarn carrier tube. The structural features may include an adaptable snagging feature that is adaptable to many different yarn types (e.g., diameter, denier, texture, material). The structural features may include projections (e.g., teeth) with incremental narrowing therebetween in the direction opposite to the rotational winding direction. The teeth may increase in sharpness (e.g., decreasing radii of curvature) as the yarn moves further into the pick-up groove.

This disclosure relates to a single-reel winding device comprising a distributor wheel for distributing an optical fiber to a first reel, a winder, for revolving the first reel around a center axis of the first reel and for moving the first reel along the center axis between different positions, an attachment device for attaching the optical fiber to the first reel, a cutter for cutting the optical fiber, a gripper for gripping onto the optical fiber, and keeping the optical fiber stationary during attaching and cutting of the optical fiber, and while the first, full reel is removed from the exchange area and a second, empty reel is provided to the exchange area in order to continue winding of the optical fiber.

An equipment is disclosed for attaching an optical fiber to a reel, the equipment including a tape supply station configured to cut and supply pieces of tape, an attachment device having a frame with a collector for collecting a piece of tape from the tape supply station for attaching the optical fiber to the reel, an actuator for moving the attachment device and for pressing the collector, having the piece of tape, against the optical fiber and the reel in order to attach the optical fiber to the reel, and a cutter for cutting the optical fiber. Such an equipment can be advantageous as manual labour can be excluded from the process of attaching an optical fiber to a reel.

One aspect of the disclosed subject matter is seen in a wire access line drum assembly that includes a tubular drum and an insert positionable therein to accommodate wire access lines of varying diameter. The tubular drum has a first and a second end and an inner and outer surface. The insert is positionable adjacent the first end of the tubular drum and has a curved channel formed therein extending between the inner and outer surfaces of the tubular drum. The insert has a ramp substantially coinciding with the outer surface of the drum at a first end portion and extending above the outer surface of the drum at a second end portion adjacent the curved channel. The height of the ramp at the second end portion is selected to be substantially similar to the diameter of the wire access line to be stored on the drum assembly.

A method for depositing a yarn end of a yarn on a bobbin wound on a tube in a defined manner during winding of yarn on the bobbin at a workstation of a spinning and winding machine includes detecting the yarn end on the bobbin via an attending device. After detecting the yarn end, the yarn end is passed to devices at the workstation, and with the devices at the workstation, the yarn end is directed in a defined manner outside of a profile of a standard yarn package wound on the bobbin prior to the yarn end being deposited onto the tube outside of the yarn package profile.

A core for winding yarn can include an oblong hollow body and a laser-cut structure disposed through a portion of a wall of the hollow body adjacent to an end of the hollow body. A method of cutting a core for winding yarn can include providing a core comprising an oblong hollow body, and irradiating a wall of the hollow body with a laser beam to form a laser-cut structure. A method of winding yarn can include placing a core on a winding mandrel, placing a tail of a length of yarn through a laser-cut structure of the core, and spinning the core to wind the length of yarn around the core. A bobbin can include yarn wound around a core including a laser-cut structure.

A system for winding wire includes a wire take-up unit and a wire cutter/grabber unit. The take-up unit includes rotatable first and second mandrel portions, and a wire directing traverse arranged to feed wire and alternately form coils on the first and second mandrel portions. The cutter/grabber unit is configured to cut the wire at a cut position between the traverse and a coil formed on the first mandrel portion and to grab a free end of the cut wire and move along a predefined cutter/grabber pathway to a hand-off position where the wire is transferred to the second mandrel portion. As the cutter/grabber is moved along the pathway from the cut to the hand-off position, a length of wire between the traverse and the free end of the wire does not decrease, and that length of wire is longer at the hand-off position than at the cut position.
