POS 3000 3D graphic control:

Interactive sheet design
POS 3000 3D graphical controls is one of the most powerful controls on the market, and because both the hard- and software come from a single provider, the SPB Evolution UD and POS 3000 3D graphical controls are a perfect match.

Working with POS 3000 is extremely comfortable:

Clearly laid-out product selection including a search function and navigation in submenus enables the operator to select work steps and connect them in the production plan menu to create sequences. Individual product profiles can be designed very quickly via the intuitive finger-activated drawing feature. The exact dimensions may be entered and changed in the dimensioning menu. In order to check and coordinate together with the customer, the drawing may be output on paper using a printer.

Using the program that is created, the software generates the optimal sequence of bends, including automatic collision and threshold value monitoring. The folding angle and cut are corrected automatically using interpolation from the database.

Unfold software – Schröder Unfold

Uncomplicated and simple

In order to coordinate hardware and software perfectly, Hans Schröder Maschinenbau developed an unfold software to calculate the blank size and program with effortless preciscion.

Vollautomatischer Werkzeugwechsler

Automated tool changer of the 3rd generation

The fully automated tool changer is from now on an equipment option for the folding machine SPB Evolution UD. The newly designed tool changer does not need an additional tool changing portal, instead a twin robot arm handles one tool each, independently and simultanously. Segmented tools for a tool change are located in two side panels on the left and right side of the machine.



Fully automated tool changer for clamping beam tools with hydraulic tool clamping device for max. tool height 300 mm. Twin robot arm handles one tool each, independently and simultanously (without toolings).


Clamping beam tools

– Goat’s foot blade, 30°, clearance 70 mm; Height: 180, 250 or 300 mm

– Hinged corner parts
