Lämneå Bruk AB Stand F11

Lämneå Bruk AB specialises in the design and manufacture of machines for the ferrous and stainless steel wire industry and is a reliable supplier of pay-offs, mechanical de-scaling equipment, drawing machines and take-up units. For the solid welding wire industry the company supplies complete lines including pay-offs, cleaning equipment, drawing machines, copper coating and take-ups. For tubular wire or flux core wire Lämneå produces strip rewind lines, strip pay-offs, forming-filling-closing machines, drawing machines and take-ups, in addition to high speed rewinding lines including precision layer and drum packer (no twist coiler) for both solid and tubular wire. For the low/high carbon and stainless steel wire industry Lämneå supplies rotating and/or over head pay-off systems, mechanical cleaning units (for carbon wire), drawing machines and take-ups. The take up systems range from down coilers with controlled filling systems to automatic spoolers. Lämneå Bruk also makes pay-offs and take-up systems for heat and surface treatment of high and low carbon wires as well as stainless steel wires, take-up coilers with live block or dead block depending on the requirements of the process.

Lubrication is one of the crucial factors for the quality of drawn wire. An interrupted lubrication in the steel wire drawing process causes an increase of surface tension in the wire, strong pressures inside the die, rapid die wear, breakage of the drawing nib and consequent non-programmed interruptions in the wire drawing process. In order to avoid these problems, Koner has studied a new concept line of drawing dies: K.340 and K.370 pressure drawing dies (patented worldwide), specially constructed and designed to improve lubrication in dry drawing of steel wire. For wet drawing the K.320 tool has been created, which allows with its particular inside geometry optimum wet drawing process characteristics and also economic saving.

❍ Vertical taping machine with sintering oven

Depending on the application, machines can be equipped with a cooling unit for the taping area, inline sintering oven or equipment for quality control. Lukas Anlagenbau GmbH – Germany Fax : +49 965 930 299 Email : lukas.voh@lukas-anlagenbau.de Website : www.lukas-anlagenbau.de Maillefer will present its portfolio of extrusion systems for energy cable, fibre optic cable, telecom cable and tube manufacturing systems. Visitors will see a series of continued improvements in the area of rubber cable insulation, filling and jacketing. The Super steam technology can provide a claimed increase in line performance of 20, 50 or even 100%, in relation to the type of cable produced on conventional equipment. When fibre optic cables made their debut in the late 1970s, Maillefer was present with equipment for the leading players at the time. Today, Maillefer provides high-end manufacturing solutions for every stage of the fibre optic cable process. Tight buffering, secondary coating, SZ stranding and jacketing lines are available for producing all kinds of fibre optic cables including premises and totally gel free FTTx cable. Technology like the compression caterpillar with tension feedback serves to keep accurate control of excess fibre length. Maillefer SA Stand F02

❍ Drawing die from Koner

The K.340/K.370/K.320 methods provide operating advantages that include production at maximum drawing speeds; less machine down- time for die replacement; better and more homogeneous wire quality; wire drawing under optimum quality control; increased nib life; overall costs reduced (only the nib is changed, rather than the entire die); and application of the requested quantity of lubricant coating to the wire. The overall dimensions of the K.340/ K.370/K.320 tools are the same as for traditional dies. Transport costs are reduced, as even large quantities of nibs can be delivered rapidly in small packages directly to customers in any part of the world. Koner Srl – Italy

Lukas Anlagenbau GmbH Stand H23

Lukas will be introducing a vertical taping machine, suitable for nearly all types of tapes such as PTFE, Kapton, mica, polyester, fleece, laminated tapes and metal tapes. The high speed and high precision taping is enabled by a closed loop tape tension control and a very precise speed synchronisation between the capstan and the taping heads.
