Accurate cutting – or fast winding – helps to ensure that extruded product is ready for sale as quickly as possible. Lou Reade reports
Making the cut
Pipe and profi le may come zooming off the line at top speed, but it’s rarely ready for sale until it’s been chopped into usable lengths – whether it’s medical tubing or enormous, thick pipe for water transport. The TGG-HB range of hot blade guillotines from
Baruffaldi is designed for precision transversal and multiple cutting – in both directions – of plastic profi les such as cable ducts, window profi les and panels, without generating burrs or dust. It can also carry out multiple cut or dual strand cutting. Because the machin e does not melt the profi le during the cut, it does not deform it – so there are no burnt residues left on the blade. The heated blade cuts large-sized thick profi les. The special temperature reg- ulator heats the blade to the optimum level to guaran- tee the same quality of cut on all profi le thicknesses. Advantages of the system include: no noise during the cut; a clean, precise cut with no dust, swarf or burrs; easy to use and maintain; and reduced produc- tion and maintenance costs. It is suitable for cutting profi les in various plastic

materials – including PVC, PC, PP and PE – and has a double-edged blade (pneumatically driven) in order to optimise the cutting cycle in both directions.
Corrugated cutting CDS of Canada specialises in putting together turnkey extrusion systems, which incorporate all the elements from the start to the end of the line. For a single operation such as cutting, it says it can
offer up to 13 variations of cutter and saw base models. From there, each standard model is confi gured according to cutting capacity, motor and drive, saw blade size as well as the shape and table travel. Its traveling planetary cutter, for example, enables 10in diameter HDPE corrugated pipe to travel along a belt conveyor through a tempered steel circular blade for severing. Lengths of pipe are programmed, and automation – by means of an ultrasonic sensor – allows sequential cutting of desired lengths on the corrugated surface accurately. On top of that, extra torque from the planetary
