Wire straightening and cutting Delisi Srl offers automatic wire straightening and cutting machines for smooth and ribbed wires from 1mm to 20mm diameter. Delisi machines are versatile and can be customised to suit the customer’s requirements. Features include the hydraulic flying shear cut. Feeding speed is regulated by hand-wheel or electronically. Feeding rolls are never changed; with the hand-wheel it is easy to select the grooves on the feeding rolls for the diameter to work. The spinner has a pre-regulated set of straightening jaws and it is said to take only one minute to change the wire diameter. The torsion is very reduced and the wire, after the cut, is cold; tolerance on the bar length is less than ±1m. An electronic programmer and one or three lines of pneumatically tiltable arms can be supplied with the rod collection bed; different lengths and different quantities can be programmed and collected separately in one of the lines of tiltable arms without stopping the machine, giving the operator an opportunity to empty the lower line of tilting arms.

Submarine cable cutters Petig’s cutter range was recently extended with the new HKS 8, designed for cutting submarine cables up to 240mm diameter, depending on the armouring. As with the other large cutters in Petig’s range, the cutters are available with either a single– or a double–acting hydraulic cylinder. Cutters with a double–acting cylinder have the advantage that they can always be opened hydraulically, even if, following a long period of use with the blades becoming blunt, a stranded conductor or part of the armouring becomes jammed between the blades. The larger cutters, which cut diameters of up to 85mm and 110mm, are now made of solid aluminium, making them 35% lighter. Cutter power has been increased and they are capable of cutting through even stronger armouring. Petig’s hydraulic cable cutters are usually driven by compact hydraulic units, with a flow rate of between 1.75 l/min and 11.16 l/min. According to the type of cutter, the working pressure varies between 250 and 600 bar. It is also possible to activate the cutters with hydraulic hand- or foot-pumps. The new HKS 8 has an additional pneumatic spring for easier opening and closing of the cutter jaws.
