Fast cycle times, easy
integration
"In compact ring systems, all the
technical refinements of the
machine enables up to 45 cycles
per minute. With a linear welding
station alignment, you can even
reach up to 75 cycles," reports
Bauder. The faster cycle times
also mean short retooling times.
"The fast program selection via
the control panel automatically
adjusts all the functions,
regardless of whether the
product is to be manufactured in
batches of 1,000 or 100,000,"
he adds.
Festo delivered the high-
performance system solution
directly to the machines at
Widmann Maschinen GmbH –
pre-tested and complete with all
the design data and circuit
diagrams. The ultrasonic welding
experts didn't just receive the
hardware in the form of a ready-
to-install sub-system – they got a
complete value creation
package.
A clever design
The gantry achieves its speed
of 4 m/s and acceleration of
50 m/s

across the entire
working space thanks to a clever
design: the two toothed belt
axes are connected to the cross-
member via a single recirculating
toothed belt that passes around
the drive shaft. The toothed belt
is driven by two servo motors
EMMS. As a positive side-effect,
there us no need to move a
motor in the X/Y plane, which
has two degrees of freedom.
The reduced mass and two servo
drives positioned in parallel
enable fast, dynamic
movement – with less wear.
Specialist in ultrasonic welding: Widmann Maschinen also processes wafer-thin plastic sheets from
thicknesses of 30 µm and upwards.
