Slotting Machines

for smooth and corrugated pipes

In-line automatic slotting machines for smooth and corrugated pipes ranging from 110 to 1200 mm in diameter. The slotting process works with a rotating rotor, equipped with one, two, three or four sets of slotting blades.

The slotting angle is adjustable for each diameter using electronic control.

All our machines are manufactured upon customer’s needs to match different types of extruded plastic pipes (PVC, PE, PP, corrugated and smooth, single or double wall pipes).
The slotting units process pipes for the drainage sector, water/liquid collection, suction severo, distribution, water pollution removal plants and related applications.

Perforating Machines

for Corrugated Pipes

In-line automatic perforators for PE and PVC, single or dual wall corrugated pipes ranging from 50 to 400 mm in diameter. Perforation is carried out by tools that automatically remove material in a synchronised operation inside the groove of the corrugation.

Our perforators are equipped with a device that automatically opens the tools to avoid line stops.

All our machines are manufactured upon customer’s needs. The perforating units process pipes for the drainage sector, water/liquid collection, suction severo, distribution, water pollution removal plants and related applications.

DRENO COVERING TNT/50-200

for perforated corrugated pipes

Machine for covering corrugated drainage pipes with PP (Geotextile), TNT disposable fabric for 50 mm pipe diameter up to 200 mm.

The Dreno Covering TNT/50-200 machine is equipped with haul-offs which pull the pipe at the same speed as the extrusion line. The pipe is covered in material in a continuous mode. The welding is also continuous and is performed by an ultrasonic welding head. Electronic controls adjust power according to the type of material and the welding speed.

The Dreno Covering TNT/50-200 machine is equipped with two coils. The first one feeds the fabric onto the pipe, the second one is only activated when the fabric on the first one runs out. This means the machine never has to stop to change over a coil. All machine functions can be set from the touch screen panel. System control is managed by a PLC and other electronic equipment (diameter changeovers between Ø 50 mm and Ø 200 mm do not require any additional tooling). The Dreno Covering TNT/50-200 is eligible to work on-line and off-line, on the flexible tube and on the rigid tube.
