are promptly evaluated and
downtimes considerably reduced.

Full equipment is standard

As standard modules, feed lengths of 1500 mm and 3000 mm are available. The feed is mounted on linear guides that are adjusted without play. It moves electrically over a gear rack and a pre-stressed sprocket and is positioned with a linear measuring system over the entire length of the feed.




Extend machines offer an incomparable range of basic standard equipment.


Inconspicuous but innovative details round out the Extend series' standard equipment. These include a custom-adjustable material removal slide and a hydraulic band tension display.


The simple, clear interface on the freely positionable control panel is equipped with a lighted, multi-line display and gives the operator status reports in plain text.


Highly precise carbide saw band guides, with acute sensors for automatic adjustment of cutting pressure on both guide arms, guarantee precise saw cuts and the longest possible blade life.

Sägebandspannung Zur Serienausstattung gehört unter anderem eine hydraulische Bandspannungsanzeige, sowie eine elektronische Sägebandspannungs- und Sägebandbruch-Kontrolle.

Saw band tensioner
Standard equipment includes a hydraulic band tension display, an electronic monitor for saw blade tension and saw band breakage, and more.



Cutting feed and cutting pressure are set individually at the control panel. The selected cutting pressure is displayed on a manometer.



ADFR – The highest precision. Faster cut.
Less wear.

The ADFR system regulates the interplay of the cutting pressure and the cutting feed automatically in real time. A sensor gives the current load on the saw band and regulates the cutting feed according to the shape of the material. For larger cross cuts to the material, the cutting channel lengthens and the saw band's load increases. If the cutting feed in these ranges is not automatically adjusted, the saw band's life drastically decreases or the cutting time significantly drops due to a lower feed.


Large-scale customization

With an Extend solution at their core, individual saw systems can be precisely configured to a flexible material handling system, based on customer needs. Lateral feed
units, roll conveyors and stop systems are available in modular designs
up to extra heavy duty.
In addition to the standard array of components, integration of special
components is also possible, from pipe processing
machines allthe way to a cartesian robot system.

NC-controlled measuring stop
with large stop jaw and automatic
pre-disconnection for propelled
roll conveyors.

Fully automatic stop for sawing pipes up to
cutting lengths of 10 m and integrated
hydraulic end expansion.

A system solution for frictionless material flow

The new X handling system offers unprecedented flexibility for tailoring a handling system to individual needs and conditions. Load capacities and automation levels can be adjusted with perfect flexibility and modified at a later time. Besides the roll conveyor in a regular and propelled version, the X system comprises a rich array of options, from vertical rollers, to length measuring systems all the way to cross conveyor units and shifting devices.


h001-enHigh flexibility
With the new System X roll conveyors, the load capacity can be customized by the number of rollers and support feet used. The roll conveyor's feed profile even allows varying roller and foot distances on the same roll conveyor unit. When needed, additional rollers and/or support feet can be installed at any time.

h002Cross conveyor units
Easy on material in a trolley version, as a chain cross conveyor or as a slide unit with pushing fingers that can be used on both sides.
Length measuring systems
The handling program offers simple, precise length measuring systems in almost unlimited lengths for custom adjustment to your requirements. The versions range from a simple, completely manual measuring stop, to a digital measuring stop with hand wheel setting, all the way to a high-precision NC measuring stop with a sensitive limit switch for cutting heavy materials to exact length in coordination with propelled roll conveyors.

Polymer concrete

Polymer concrete - tried-and-true high-performance technology


Low-vibration saw cuts mean precision and long life Polymer concrete offers the ideal damping characteristics for use in saw machines.

On all Extend machines, the support, saw frames and columns are filled with a specially developed polymer concrete mixture.

Coupled with pre-stressed, play-free, generously dimensioned linear guides, polymer concrete technology provides virtually vibration-free saw cuts with high cutting performance far above 100 cm2 per minute with M42 bimetal saw bands.



Tailor-made from the series

The ideal slope setting of the saw frame to the horizontal clamping surface depends on the shape of the material, and on the designated sawing process. The Extend series' machine design allows this parameter to be set individually.

0° Slope

For processing solid material and as a standard when using sliding tables with swivelling saw band guides for horizontal cuts

2° Slope

For universal use of the saw machine, an ideal compromise between the 0° and 6° slopes.

6° Slope

When profiles and carriers are separated, the cutting channel in the horizontal area of
the material is held for a very short time. It is thus possible to use a finer saw band,
and this considerably improves the cutting feed and precision.


Solutions to unusual challenges

Large work pieces with nonstandard shapes, such as castings, call for a simple,
flexible solution. The Extend series' slide units allow custom clamping
designs and precise positioning.

The slide units have clamping plates with T-grooves and can be custom equipped with connections for hydraulic clamping devices. The clamping plates are mounted on play-free, pre-stressed linear guides and are positioned hydraulically or mechanically.

The hydraulically swivelling saw band guides
adjust the saw band 90° and, in connection
with a slide unit and a hydraulic saw frame
clamp, allow horizontal cuts and special
notch cuts on a vertical axis.


Individual solutions

Productivity through individual solutions

With the Extend series' many capabilities, adjusting the material tension
on the work piece is no challenge at all. Individual clamping
configurations can be put together from existing components
without the cost of special designs.
