Waste extractor

Keep your machinery free of waste

An air extraction system that removes the loose cut-out material and sucks it away before it spreads all over the press.

  • 01 Several compressed-air nozzles, adjustable in axial position, blow on the material so the waste comes away from the part.
  • 02 A collection mouth underneath, connected to the suction system, collects the waste.
  • 03 A single pneumatic supply distributes air to all the nozzles on the bar.
When it’s needed

Two jobs that get complicated without it

Case 1

Circular cut-outs

When circular shapes are cut out, the air helps separate the waste slug.

Case 2

Internal die cuts

When shapes inside the label itself have to be removed, it makes sure the waste comes out whole.

Made to measure

Made for your press

No two are the same: it is made according to the available space and what each customer needs. It is integrated right after the die-cutting, with whatever mechanical adaptation is required.

As many nozzles as the job requires are fitted, and they are positioned by hand according to the shape being die-cut.

How it works

Blows from above, sucks from below

The extractor is mounted between the press units, right after the die-cutting. The web passes tangent to the upper mouth, where the nozzles blow on the material to lift off the cut-out. Below, the collection mouth is connected to the suction, which carries the waste away through the pipe before it spreads around the press.

Where the web goes in and where the waste comes out. The unit fits in the gap between two press units, without getting in the material’s way.

The collection

The waste falls into the hopper and the suction carries it away through the pipe, in the direction shown by the arrow.

Where the extractor fits in

It goes right after the die-cutting, and works with the rest of the equipment that gets the web ready for finishing.
