Cutting cables the Petig way . . .

For many years Petig has been among the leaders in the field of hydraulic cable cutters. Long before the hydrocut steel cutter made its appearance in the wire rod mills of the world, the first cable and wire rope cutters had been presented to Petig customers. Since then a vast family of hydraulic cable cutters has resulted. The cutters, which are made in eight sizes, have differing capacities. The smallest shear cuts to a maximum diameter of 16mm while the largest shear copes with a maximum of 225mm. All the larger cable cutters are available with both single and double- action hydraulic cylinders. The double-action cylinder has the advantage that if, following a long period of use, a strand or integral part of the sheathing should jam between the blades as a result of wear of the blades, the latter can be opened using hydraulic power. PS Costruzioni Meccaniche has launched a new, improved double head fully automatic spool winding line. The enhanced features are most noticeable in regard to the restart time between one wound spool and the next one. While the first spooling head is winding the cable, the second head has com- pleted the winding cycle, enabling the final spool to automatically proceed to the palletising area. The PS 200/6/B enables customers to double normal machine output, thanks to the two winding heads working at the same time. This machine can accommodate approximately 200 cardboard, aluminium, plastic, plywood and wooden spools which are located in two separate stores. The spool ranges are flange outer diameter from 100mm (3.94") to 200mm (7.88") and flange width from 50mm (1.97") to 190mm (7.49"). PS 200/6/B process specifications are: Bore centreing (to start the winding operation); Cable layer on layer winding; cable measuring accuracy ±0.1%; Spark tester cable insulation tests Pneumatic and fast cable cutting; • • • • • New automatic spool winding line

A vast range of cable cutters

It is also possible to activate the cutter with hydraulic hand or foot pumps. Most recent Petig developments are the HKS5 and HKS6 series made of solid aluminium. This significantly improves manageability of the cutter through a weight reduction of up to 35%. Friedrich Petig GmbH – Germany Fax : +49 2181 73108 Email : info@petig.com Website : www.petig.com

The larger cutters, which cut up to 85mm and 110mm, are now made of solid aluminium. This saves about 35% of the weight, and gives an increase in the cutter power because of this design change. The hydraulic cable cutters are usually driven by compact hydraulic units, with a flow rate between 1.75l/min and 11.6 l/min. Depending on the type of cutter, the working pressure varies between 250 and 600 bar.

End-product packaging by polye- thylene film; Division between end-products with insulation defects and correct end-products; Labelling; Palletising (a Cartesian axis palletiser); Pallet wrapping. The machine can produce more than four spools of 100m (328.08ft) per minute while cable sections can vary from 0.65-6.53mm 2 (AWG from 19-to 9). • • • • •

The wireguide comes with CNC digital technology, and special CNC software helps to obtain perfect winding results. An in-line cable diameter detector can be included which can correct any cable diameter modification in real time.
