RoofCut Series
for tapered insulation and roof insulation components made of EPS, Neopor and XPS

Tapered boards with up to 10 cutting wires

For manufacturing tapered boards made of EPS and Neopor, the RoofCut Series works with a multi-wire system with up to 10 cutting wires.

The cutting wires are hung in manually according to the desired board thicknesses and slope angle and then cut up to 10 tapered boards at once from a single block.

Instead of cutting each tapered board individually, several finished boards are produced in a single cutting operation.

Especially for recurring board dimensions, this enables economical series production and high production output.

CNC contour cutting with a single cutting wire

Valley and hip boards, roof crickets, insulation wedges and custom contours are cut CNC-controlled with a single cutting wire.

The four CNC axes can be moved independently of one another. This allows the cutting wire to take up different positions and heights on the left and right sides.

In this way, valley and hip boards, roof crickets, insulation wedges and custom contours can be cut precisely and reproducibly.

Cross-cutting EPS and Neopor blocks

EPS or Neopor blocks with a standard length of 2,000 or 3,000 mm can be cross-cut directly on the RoofCut to the 1 × 1 m format required for roof insulation production.

From a 2,000 mm long block, for example, this produces two blocks of 1,000 mm length each.

Alternatively, cross-cutting can be done separately with a GT1300S cut-to-length machine .

Processing XPS boards with the pendulum cut

On the RoofCut Series, XPS is processed as board material.

The board is placed on the machine table and cut with a single cutting wire according to the desired slope. This produces two tapered boards from a single board.

The next board is then placed on the table and the cutting wire travels back in the opposite direction. In this way the boards can be cut alternately in both travel directions.

This avoids unnecessary idle travel and XPS boards can be processed efficiently one after another.

The material determines the cutting speed

With EPS and Neopor, typical cutting speeds are around 400–650 mm/min.

XPS is cut more slowly. Here, typical cutting speeds are around 350–400 mm/min.

The machine could travel much faster, but the cutting wire cannot cut the material any faster. In hot wire cutting, the heated cutting wire must melt through the material without touching it mechanically. The limiting factor for the cutting speed is therefore the cutting wire.

What matters is therefore not the maximum travel speed of the machine, but a stable cutting speed with a clean cut result.

Typical production times

10 tapered boards 1 × 1 m: approx. 2–3 minutes. Thanks to the multi-wire system, up to 10 tapered boards at once can be cut from a single block.

20 valley or hip boards: approx. 40–50 minutes. Valley and hip boards are cut with a single cutting wire.

1 roof cricket: approx. 45 minutes. A roof cricket consists of about 20 individual segments and therefore requires a correspondingly longer cutting time.

These figures are practical values and may vary depending on material, dimensions and cutting task.

For EPS, Neopor and XPS the RoofCut Series works with our TiTA64 cutting wire.

The TiTA64 cutting wire is specially developed for the hot wire cutting process and resistant to heat glow and tearing.

Depending on the application, TiTA64 cutting wires with a diameter of 0.35 or 0.40 mm are used.

When heated, the TiTA64 cutting wire expands and becomes longer. The tensioning springs absorb this change in length and keep the wire under tension during cutting. This prevents the cutting wire from sagging during cutting.

For a clean and reproducible cut result, the quality of the cutting wire is decisive.

The TiTA64 cutting wire and tensioning springs are wear parts. Both parts can be reordered directly from us when needed.

Operating the RoofCut is very simple. To manufacture your roof insulation components you need no drawings.

For tapered boards you hang in the cutting wires according to the desired board thicknesses and slope angle and start the cutting operation. No drawing, no programming – just cut.

Many of our customers learn the operation and applications independently using our instructions and training materials.

In addition, we offer software and application training at our premises in Ilmenau, on site at the customer or online via TeamViewer.

Manufacturing customer orders

Tapered boards, valley and hip boards, roof crickets, insulation wedges and custom roof insulation components can be manufactured directly to customer order.

This allows you to respond to different roof geometries, changed dimensions, special parts or roof insulation components needed at short notice directly in your own production.

Smaller quantities and follow-up production can also be manufactured at short notice, without having to order the required roof insulation components externally.

Producing roof insulation components for stock

Frequently needed roof insulation components can be pre-produced and put into stock. This lets you respond to new orders faster and independently of external delivery times.

Stable, open machine table

The machine table is made of a stable steel construction and is designed for daily production operation.

Thanks to the open design, the table is freely accessible from all sides. EPS and Neopor blocks as well as XPS boards can thus be easily placed, aligned and removed again after cutting.

This makes switching between different material formats and cutting tasks especially easy.

Steel-reinforced belt drive

The axes of the RoofCut Series are driven by steel-reinforced toothed belts.

This enables smooth movements, fast direction changes and precise positioning of the cutting arms.

Especially with EPS and Neopor, the belt drive is insensitive to material particles and is easy to clean.

Additional lubrication of the drive is not required.

4 independently controllable CNC axes

The RoofCut Series has 4 independently controllable CNC axes.

This allows the two sides of the cutting wire to be positioned independently of one another. The wire can take up different heights on the left and right.

In addition to straight cuts, this makes it possible to cut tapers, valley and hip boards, roof crickets and custom contours.

The programmed movements are executed precisely and reproducibly by the CNC control.

Multi-wire system with up to 10 cutting wires

For manufacturing tapered boards, the RoofCut Series can work with up to 10 cutting wires at once.

The cutting wires are hung in manually according to the desired board thicknesses and slope angle.

This makes it possible to cut up to 10 tapered boards at once from a single block.

For custom CNC contours, on the other hand, a single cutting wire is used. In this way the RoofCut Series combines multi-wire production and CNC contour cutting in a single machine.

Control console directly at the machine

The control console is located directly at the RoofCut and creates a fixed workstation at the machine.

Computer, monitor, keyboard, mouse and the controls for machine operation can be clearly arranged at a single workstation.

As a result, machine operation, software and production documents are located exactly where they are needed during production.

The control console is part of the standard equipment of the RoofCut Series.

Control PC package

Optionally, we deliver the RoofCut Series with a fully prepared control PC package.

The computer system is prepared for machine operation and comes with a current Windows Pro license. Machine software, interfaces and control are already matched to one another.

All computer systems from cnc-multitool have a second SSD drive as a backup drive.

TiTA64 cutting wire and tensioning springs

TiTA64 cutting wire and tensioning springs are consumables and spare parts for the RoofCut Series.

We recommend keeping cutting wire and matching tensioning springs in stock as replacements. Both parts can be reordered directly from us when needed.
