An automatic cut and transfer coiler and spooler apparatus, system and method for use generally comprising a rotatable turret with two independently driven spindles thereon wherein the drives for the independent spindles are attached to the turret for selectively rotating the spindles about their own axis independently.

A filament-reinforced composite material having with load-aligned filament windings enables improvement of mechanical properties for specific loading of parts made from the material. The orientation of the winding within the part may be changed depending on an orientation of an external load to the part. In one example, the part may be a slip in a frac plug or a bridge plug in a downhole application.

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.

A device and method for cutting-to-length surgical suture material uses a thread spool having a continuous thread of the surgical suture material, a thread advancing gripper for drawing off a defined length of surgical suture material, and a cutting unit for cutting the surgical suture material. By way of a deflection installation, the surgical suture material is placeable so as to be angled to the primary transport direction in at least one open loop. The length of the open loop can be variably adjusted. The cutting unit is positioned between the thread spool and the deflection installation.

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.
