New High-Speed Taping Line Applies 2 tapes/head onto small wires Company has manufactured and now offers a new compact high-speed taping machine that can precisely apply up to two individual tapes per head onto small round or rectangle wires. The state-of-the-art modular design of this machine also means it can be built to different specifications such as one, two or three bay. Twin servo-motor technology ensures the fast and accurate application of the applied tapes. The taping head is designed to accommodate both flat and cross-wound tape pads to suit the required application. The HTM-Configurations can be used to apply a variety of materials including, but not limited to, PTFE, Mica, Paper, Nomex®, Polyester, Aluminum/ Mylar and Kapton®. The company supplying this new high-speed taping line is a leading manufacturer of precision taping and winding machines for the electrical and energy industries, with over 90 years engineering experience. The company’s machines are widely used for manufacturing electrical coils, cable and conductors. Additionally, these precision taping and winding machines can be utilized for the manufacture of Reinforced Thermoplastic Pipe (RTP) for oil and gas pipeline applications. From innovative flexible designs to worldwide customer support, The manufacturer of this equipment provides expert solutions that have been developed from a close understanding of customers’ individual needs and requirements.

Remote subsea wells may also be connected to a platform by flow lines and by umbilical connections. Frigeco has developed/installed large planetary stranders for assembling umbilical cables deployed on the sea beds to supply necessary power, control, communications, utilities and chemicals to subsea oil and gas platforms and wells. Some constructions include members that require minimum bending requirements and are required to be abrasion resistant. These armored umbilical cables have breaking strengths in excess of 200 tons. They incorporate many different types of constructions and metallic sheaths and steel or synthetic strength members. The company’s machines can handle 24 main bobbins of 3000 mm (10') diameter and 20 filler bobbins of 1650 mm (5' to 6') diameter. The maximum weight of each of the main bobbins is 30 tons and the filler bobbins are 3 tons maximum. Operating speed is 15 RPM with a 45 mpm maximum linear speed. Filling stations with integrated loading systems can be added. Most of these large undersea cables also require significant armoring wires to protect them once deployed. These steel or galvanized steel wires, flat or round, are also applied using a planetary strander. A typical planetary strander (in photo), handles 72 to 800 mm bobbins weighing over a ton. And the cable can be up to 300 mm diameter. These machines can also be placed in tandem. The MFL GROUP continues to make improvements to its machines to reduce overall operating costs. Frigeco USA, Inc., Annandale, NJ, USA. www.mflgroup.com Drum Twisters For a range of cabling applications Company is known for roll forming of compact aluminum conductors using Single Input Wire (SIW) technology inline with conductor stranding. The firm’s roll forming technology is available on all of its stranding machine types. This technology combined with large double twist or single twist take-ups yields a highly efficient system for producing large compact aluminum conductors. The company offers drum twisters for a wide range of cabling applications including optical, composite, shielded instrumentation and control, telecom, power and specialty cables. Drum twisters, also called universal cablers, are used to cable a wide range of products, and also to apply steel wire armor, concentric neutral wires and tapes. Rotating and linear tape heads are used to apply tapes of all types including Mylar, aluminum/Mylar shielding, copper, semi-conductive, bedding and woven. Drum twisters are used to close shaped elements to form Milliken segmented conductors, and sectored cables. Drum twisters may operate in either rigid mode (100% back twist) with static payoffs, or in planetary mode (no back twist) when fitted with neutralizing payoffs. Dual wheel capstans and/or rotating caterpuller capstans are also available. The company’s goose-neck traverse design produces high-quality cable and winding as it supports and guides the cable from the entrance of the take-up to the winding point on the reel reducing product stress and tension fluctuations. Drum twist take-ups and rotating or static payoffs are offered in multiple configurations and sizes to meet specific product requirements. Roteq Machinery Inc., Toronto, Ontario, Canada. www.roteqmachinery.com Improved SZ Stranding for Fiber Optic Cables Optimum cost-performance ratio Companies’ SZ-Stranding for fiber optic cables has been improved with a concept that perfectly coordinates performance and costs in one line. What has been achieved is an extremely low total cost of ownership (TCO). This is a result of higher overall equipment effectiveness (OEE) and longer product live-time, with fewer spare part needs. The line itself is designed for a short set-up time, which also supports increased OEE. Speed is a key factor of performance. With line speed up to 200 mpm, the loose tubes are stranded at an impressive 2500 rpm. But speed alone does not fulfill all the requirements a manufacturer has on a production line. Integrated components also have to react precisely at high speeds. The new ROBI cross binder keeps up with the speed while at the same time securing low tension for the stranded bundle. The active yarn tension control ensures that the tension does not harm the tubes or bundle. When it comes to thin-wall products, the ROBI demonstrates accurate binding quality with perfect tension—even when crossbinding soft tubes or soft bundles. Currently, the OFC 70/RL-R SZStranding line offers the shortest reversal time on the market. We can also provide your own tailor-made lay plate design depending on your product mix. DPT is the companies’ solution for space-saving payoff design for loose tubes. The integration of two payoff positions in one common machine frame helps to save shop floor space. The DTP is available in two sizes, either for spools with up to 800 mm or up to 1000 mm flange diameter. Especially regarding product designs with two or more layers of stranded tubes, the DPT can reach its full potential in terms of space savings.

Is your line equipped with technology and electrical components, which are not state-of-the-art or are outdated? Products change over the years and the market demand shifts now and again. This is why a line modification should be evaluated from time to time. It is important to analyze the production target and resources. Following a relatively small investment, it may be possible to increase the line’s performance and reliability and to meet today’s demands. The right upgrade often imparts the same benefits as new equipment. Automated control system technology expertise and process knowledge help to evaluate upgrade possibilities and provide process support for the line upgrade. In combination with appropriate measures, the return on investment will be feasible within months. The companies offer a wide range of customized upgrades from single components and line control systems to entire electrical cabinets including the latest PLC and AC-drive technology. These systems help to make sure you will get the most out of your equipment for many years to come. Efficient upgrades result in increased overall equipment effectiveness, higher production flexibility, reduced maintenance costs and increased spare parts availability, optimized production process and short ROI and expanded capabilities due to greater line control functionality and usability.
