Take-up and payoff combined in one machine

Swedish wire machinery manufacturer Lämneå Bruk offers a broad and customisable portfolio of payoffs and take-ups to maximise plant efficiency for an international customer base. One of the company’s latest innovations is the No-Twist Coiler (NTC) 1200, which combines take-up and payoff in a single machine. The machine can be used off line or, more effectively, in-line with the drawing machine. The NTC 1200 acts as take-up for the drawing machine, while the inverted carrier is used as payoff in the next production step and placed directly onto the floor. One of the main advantages is the handling of the package as undriven payoff, resulting in twist-free and straight wire. This also leads to quicker changing and set-up times. The machine is also an energy saver, as it avoids the need to run separate take-up and payoff. The No-Twist Coiler enables unlimited speed in the wire take-up. The versatile NTC 1200 is suitable for all applications for wire diameters from 0.3 to 14mm.

Environmentally friendly cable protection

which fixes the amount of material per running metre of pipe. To save costs, recycled materials are often used, but their property profiles and processing characteristics are dependent on the batch. Another approach to reducing costs and plastic consumption is to physically foam the pipes. Environmentally friendly gases are injected into the plastic and mixed with it in the extruder. In the subsequent pipe extrusion process, these gases form a fine pored foam that leads to weight reduction and savings in plastic.

Plastic pipes for protecting cables in the ground are available in a wide variety of diameters and wall thicknesses. To ensure that the cables inside the pipe are protected from environmental influence and damage, appropriate standards must be met that clearly specify the properties of the conduit. Among other things, these standards specify the diameter/wall thickness ratio,
