KESEL Automatic Band Straightening Machine BR-32

Bandrichtmaschine
The automatic Kesel band straightening
machine was primarily developed for
straightening the longitudinal camber
of metal bandsaw blades.The machine
type BR-32 allows to straighten a range
of 20 – 80 mm (3/4 – 3 1//8 inch) of
band material.
The machine can be ordered in two
design options regarding the coil
handling direction -left to right (BR-32 L)
and right to left (BR-32 R).
Measuring Stations
Mess-Stationen
The machine is equipped with
two floating-mounted measuring
stations.One station measures
the camber of the incoming
(unstraightened)band,the
second station measures the
result of the straightened band.
The results of measurement are
displayed on the screen and can
be documented.The measuring
sensors are LVDTs equipped
with carbide tips.


Roller Positioning Unit

The pairs of straightening rollers
are manually adjustable in
horizontal position.Therefore,the
straightening track spacing can be
adjusted for each individual band
width.


Loop Control
Schlaufensteuerung
Ultrasonic sensors measure the
horizontal position of the band
loops for the incoming as well
as the outgoing band.The
control unit regulates the
rotational speed of the coiling
systems.


Control Unit
Steuerungseinheit
The control unit consists of an industrial
PC and a Windows visualization system.
The machine operation and set-up are
made via a touch screen.		       . Straightening Rollers
Richtrollenpaare
Two hydraulically operated
pairs of straightening rollers
represent one straightening unit
which is controlled by a specially
developed software.The bands
are arranged horizontally,thus
the pairs of straightening rollers
are arranged vertically.The
advantage of a horizontally
positioned band lies in the fact
that the band material ´s own
weight does not falsify the
results of measurement.


Electrical Cabinet

The electrical cabinet contains
the complete high voltage
components and the frequency
converters of all drives.An air
conditioning unit is opitional.

Coiling System
Haspelanlage
The coiling system can be
operated in both directions.
Tilting the coils 90 degrees for
horizontal loading is optional.
Protective disks prevent damage of
bandsaw blade teeth.The control
regulates the rotational speed of
the coiling systems.Control
buttons for start/stop/emergency
stop,coil retaining arm and coil
tilting (optional)are directly
mounted at each coiling system.
