Plus extrusion cutter com- bines a servo motor with a

activate the knife blade
motor with a digital control system to activate the knife blade. Very high cut rates are possible, along with precise cut length accuracy. New widescreen touch panels allow easy operator control of the machine. The cutters are available in three maximum diameter sizes; 30mm, 40mm & 100mm. Matching twin-belt Accra-Feed caterpillar infeeder/pullers are provided to match every machine. Multiple lane configurations are available to handle up to six separate extrusions. Remote wireless support via the Internet is now
standard, and all the machines are fitted with a 3G antenna for use with a local-rate SIM card. The company also used K2013 to launch a new servo
coiler – a compact twin-head machine. The vertical configuration of the reeling drums reduces the footprint of the machine, to save valuable floor space. The servo traverse allows for fine coiling adjustment. There is also a non-contact sonar speed control system for very low tension winding, which Gillard says is vital to avoid product distortion during the coiling process.
Sica’s TRK/C 2500 planetary saws is designed for cutting HDPE pipes with large diam- eters and thick walls
Dual coiling There were other coiler launches at K2013 – including the TCA range of automatic dual coilers from Maillefer, which was a redesign of its earlier MWB series. The company says it was developed in response to demands for a coiler that was ergonomic, safe, robust, reliable, easy to maintain and financially attractive. “Our design team had a long wish list to respect,” said Philippe Moeschler, operations director at Maillefer in Switzerland. “They had to come up with solid answers that addressed cost, quality, technology, and perfor- mance constraints while meeting customer demands.” Two models are available: the TCA 1000 and TCA 1300. “Modern construction methods allow us to build a machine more quickly and efficiently,” he said. “Critical moving parts, like the strapping components, are reinforced for a highly repetitive operation.
Cycle times – the time taken for reel-to-reel transfer
– have been reduced by up to 33% on average. The technology is completely new. Smart functions are built-in, which anticipate tasks and commands from the operator. A full safety analysis was done on the machine in order to have it equipped according to international standards. “We’ve built a better and smarter coiler,” he said. Maillefer’s line of automatic dual coilers and reelers
cover a wide range of applications. The two new models specifically cater for manufacturers of micro-drip irrigation heavy wall tube, heating and plumbing pipe, automotive fuel and vapour tubes and other special pipe constructions, he said.
Geothermal handling The Unicoil range of coilers from Balzanelli are geared towards handling geothermal pipe. Developed from the technology of its earlier TR
range of automatic coilers with opposing reels, the Unicoil range overcomes the problems of handling and packaging geothermal pipe, and makes it possible to coil pipes on two reels at the same time. Fitted with a small haul-off device and a special
latching unit, the Unicoil allows the creation of coils which all have the same length, with the pipe tail always ending up in the same place. This makes it easier to pair up the single coils and to insert probes. It also claims savings in production costs, as it helps to
reduce the labour costs needed for handling and manag- ing the product, as well as saving cost on packaging materials – and ensuring a neater appearance of the coil. The machines also require limited installation space, and no special area for the storage and coil coupling phase is needed. Coils are ready for insertion of probes the minute they leave the machine, says the company.
