The new D 1001 double twist buncher
NIEHOFF has just recently introduced the latest addition to its
D-series family of bunchers: The D 1001.
This new buncher is designed in two versions: A copper buncher
capable of processing stranded cable up to a maximum cross section
of 50 mm² (1/0), and an aluminum version capable of producing aluminum
strands up to a maximum cross section of 60 mm² (1.5/0). Lay
lengths can be infi nitely varied up to 300 mm, while rotational speed
can reach a maximum of 3,200 twists/min.
The D 1001 is optimally suited for large wire rope lay strands and battery
cables of copper and aluminum, and is available both in left and
right-hand versions.
With spool fl ange diameters up to 1000 mm, and spool widths up to
750 mm, this buncher is capable of handling the widest of the DIN1000
spools. Spool changeover is easily
achieved using the electrical
spool lifting mechanism and the
pneumatically powered pintles.
The D series family of bunchers allow full coverage of a wide range
of bunched products from fi ne to heavy strands, i.e. 0.013 mm²
to 50 mm², which is an advantage to minimize equipment cross training
requirements of operators in the bunching department.
The NIEHOFF bunchers are operator friendly and economical to
operate. One major feature of this series of bunchers is the single bow
design resulting in considerable energy savings and noise emission
reduction compared to conventional bunching machines.
The number of slip rings has been reduced through the use of telemetry
for data transfer. Slip rings are used only for power transfer. The result is
a reliable troublefree operation with reduced maintenance and downtime.
Winding tension throughout the spool fi lling cycle is controlled via a
load cell and dancer situated in the spool carrier. The driven haul-off
