New development for the automatic die working machine

needle exchange device, it is possible to perform this with a completely automatic workstation. All three steps such as grinding, polishing of the cone and processing of the cylinder are fully automatic. The demand and the urgent requirement of the wire processing industry to such intelligent solutions for process observation will grow even stronger in the future.

manufacturing process with improved manufacturing tolerances. Beside the quality observation, the safety of the process and observation of the die quality is of crucial importance. The machine is equipped with an automatic needle exchange device and a fully automatic measuring system, which sends the data of the manufacturing process to the controller. This allows the automation of a small series without the intervention of staff members to switch the measuring pins. Because of the

The costs for product quality have mainly been spent by the dies and their manufacturing tolerances, which have been determined throughout the drawing hollow. In order to get along with the requirements, it is necessary to use an improved drawing tool. The resulting requirement of the improved die geometry requires a sustainable further development of the currently used die-working machine. The target of the new development was a secure and efficient observation of the die working geometry during the Coats plc, an industrial thread and consumer textile crafts business, has made a unique enhancement to its Ultrabloc S/SC range that protects delicate fibre optic cables against the damaging effects of sea and salt a water-swellable yarn, suitable for dry blocking in fibre optic cables. It is appropriate for use in any application that requires no mess processing and soft, uniform surfaces around the cables, such as inside and outside tube blocking, to produce completely dry cable designs. Coats Ultrabloc S is a spun super-absorbent polymer yarn, while Ultrabloc SC incorporates a polyester core for added strength. These yarns have been tested and proven to withstand temperature cycling, heat aging, and freeze/thaw testing. One of the benefits of Coats Ultrabloc is that it eliminates the need for gel inside tubes, allowing for totally dry fibre optic cables. Dry cable designs are preferred by service providers because they are lighter in weight and water. Coats Ultrabloc S/SC is

time and money in cable processing due to reduced machine setup time and increased machine lifetime. Coats Ultrabloc S/SC is used throughout the cable industry for loose tube, ribbon or central tube optical fibre cables, and for energy/power cables. Shantanu Banerjee, managing director, global speciality, Coats plc, said: “The technological enhancements in Coats Ultrabloc S/SC are a world first for the totally dry cable market. The range can now protect against sea water which has a damaging effect on fibre optic cables. Coats Ultrabloc S/SC is yet another example of Coats’ varied portfolio of apparel, footwear and speciality thread, yarn and zip innovations.” Coats Ultrabloc S/SC yarns are now also available on fibre reels.  This allows for easy introduction and processing on existing buffer tube lines with no need for tooling or modifications to existing lines.  It also allows for more precise tension control.

make installation and repair of cables much easier and more cost efficient. Coats Ultrabloc S/SC yarns have extremely smooth surfaces because they are not coated and are spun on state-of-the-art equipment for precise diameter and quality control. The smooth outer surface provides less chance of signal weakening in the cable, which can lead to loss of signal strength. Since there is no coating on the yarn there is no ‘shedding’ or ‘dusting’ during cable manufacture. Having a much cleaner procedure can save both ❍ ❍ Coats Ultrabloc is used to protect delicate fibre optic cables against the damaging effects of sea and salt
