aerodynamic design of the bow have been developed to minimise friction and loss and therefore to reduce the consumption of electricity. Additional advantages are easy maintenance (it has a removable tube) and the fully closed design results in fewer bow crashes.

GCR Eurodraw has designed a new device to increase the efficiency of a PC wire line by reducing the threading time to just a few minutes. PC wire lines are generally difficult to thread and a wire break immediately translates into a loss of several hours of production. GCR Eurodraw’s PC wire double capstan automatic threading device is said to thread wire onto a 3m double capstan in around 5 minutes. A manual threading operation would require at least two hours. The system can be added to any type or brand of PC wire line with horizontal axis capstans without any electrical or mechanical modification. The unit consists of a large frame, supporting a motorised threading trolley. The frame carries a track with same perimeter as the pair of pulling capstans. A motorised threading trolley travels on these tracks and goes around the capstans, placing the wire in the capstan grooves. The trolley goes around as many times as there are pulling grooves on the capstans. The speed of the threading trolley is synchronised with the speed of the PC wire line. Once the wire is threaded, the system retracts into a stand-by position waiting to be re-activated on the next wire break or wire size change. GCR Eurodraw will also introduce a compact in-line cleaning system composed of a processing tray and a heated water circulation tank. The combination of brushes and hot water jets removes and dissolves most of the wire drawing lubricant present on the wire. No smoke is generated by the furnace, leaving the working area smoke free. There is no accumulation of burnt soap in the furnace, which over time can reduce the efficiency, cause failures and require maintenance, and there is no pollution of the quench water after the furnace, as the cleaned wire cannot deposit burnt residuals into the water.

Gauder Group’s new concentric stranding line, COS 1200-2, has been designed with energy savings in mind. Power consumption has been reduced: to strand 150mm 2 uses only 40kW of power for the complete line, or 36kW for 120mm 2 . This is thought to be far lower than using a conventional stranding line. It is the result of using regenerative power from the large and heavy built-in reels to produce electricity through a bus connection, so the reels become power generators. A second means to reduce power use is by adapting equipment for lower energy consumption. For example, high-speed double twist twinners or bunchers have been equipped with Gauder Group’s new GreenBow, saving 30% energy use on bow motorisation. An advanced composite material and special

Gauder 集团的新同心绞缆生产线 COS 1200-2 已设计出来，节省能源。降低 了能耗：整条生产线 150 平方毫米只 使用了 40KW 功率， 120 平方毫米只需 36KW 。这比传统绞缆生产线消耗的功 率低了许多。 这是使用可再生功率的结果，通过母线 连接，从大型和重型内嵌线盘发电，因 此线盘成为了功率发电机。 第二种减少使用功率的办法是适当运用 低能耗的设备。例如：高速双绞机或束 线机配置 Gauder 集团的 GreenBow 新产 品，在机械化弓形件方面节省了 30% 能 源。先进复合材料及特殊气动设计，尽 量将摩擦和损失降至最低，因此，减少 了电力损耗。还有其它优点：维修简单 (有可移动管)，全封闭设计使得弓形件 之间很少有碰撞。 sales.pourtier@gaudergroup.com Website : www.gaudergroup.com Bow Technology by Gauder Group – France Fax : +33 4 77 71 10 85 Email : bowtechnology@gaudergroup.com Website : www.bowtechnology.com Gauder Group – France Fax : +33 1 64 26 61 10 Email :
