Breakthrough in breakdown
technology
Headlined as “Rod breakdown with breakthrough tech-
nology,” Sampsistemi launched the RBL 1 at this year’s wire
Düsseldorf. The RBL 1 design includes continuous, high
precision process control that saves energy and materials.
Working with copper or aluminium alloys, the RBL 1 rod
breakdown line will handle between 9 and 17 drafts of 1,
2 or 4 wires at speeds up to 40m per second. Wire elongation
per draft is fully variable and selectable.
The inlet diameter for copper wire is 8mm–10mm,
or 9.5mm–12.7mm for aluminium alloy; the outlet
diameter is between 0.88mm and 5.5mm for copper, and
1.25mm–5.5mm for alloy.
Advantages of the RBL 1 over existing technology are said
to include:
CNC process control •
Diameter or conductivity operation modes •
30% less energy consumption •
Quieter running, less than 80 dBA •
Oil-free, direct drive technology •
Operator-friendly supervision and diagnostics systems •
Remote control via Internet connection •
Requires no preventative maintenance •

Optical length and
speed measurement The FMS-webMASTER 040 series of steering frames and the
new BKS309 web guide controller form a sophisticated web
guiding system for even the most demanding applications
including unwind and rewind stations on extrusion, coating
and laminating lines, and intermediate splicing, packing or
printing stations.
The FMS tradition of providing low cost-of-ownership solutions
is continued with the FMS-webMASTER 040 series web guides.
The steering frames of this large web guide family are available
with roller-spans of 600mm to 2,000mm. Standard features
such as a stepper motor drive (no brushes), a robust ball screw
and spindle assembly (preloaded to eliminate backlash) with
lifetime lubrication, and oversize ultra-low-friction sliding
guides form the basis for years of operation. Signal processing
and controlling tasks are fully digitalised, resulting in a fast
1 millisecond cycle time and thus the ability to succeed in
applications where higher web speeds prevail.
The BKS309 controller is available in wall, DIN rail, and panel
mount versions, and a single cable provides both power and
control interfaces between the steering frame actuator and the
controller. The controller is equipped with an Ethernet interface.
All products from FMS are designed as plug and play units,
and all functions can be configured using the user-friendly
control panel or a PC.

Web guiding system
In highly automated production processes, length and velocity
data are required for many purposes. For instance, measurement
of operational throughput delivers essential data to control
process parameters. In the manufacturing of piece goods an
automatic start and end recognition mechanism enables an
autonomous length measurement.
For a variety of materials, especially those that are hot, elastic,
highly sensitive or dough-like, it is impossible to use tactile sensors
such as odometers or tacho rolls.
The accuracy of a mechanical sensor system is also reduced
by slippage, which in practice can lead to measuring errors of
10% or more.
In both cases, non-contact optical metrology provides significant
benefits. With the Speel 3000, Zumbach offers a high-tech gauge
that can be used for a wide range of applications requiring
accuracy at very high velocities.
The Speel 3000 is available for a measuring distance of 300mm
and achieves an accuracy of 0.05% or better. The measured
length is transmitted to subsequent electronics using an industry
standard incremental interface. As an alternative, a synchronous
serial interface (SSI) is also available.
In addition, an electrical output signal compatible with common
incremental encoders is available and can be directly connected
to control systems, electrical counters, or frequency inverters.
The main features of Speel 3000 include:
Speed range up to 3,000m/min •
Detection of standstill •
Detection of direction •
Start and end recognition •
Allows deviation of the measuring distance •
Suits smooth and rough surfaces •
Long life LED illumination •
Maintenance free •
