of the machine:
Robust cast housing.
The technically mature design guarantees high production
numbers with a clean cutting performance. The excellent
performance of the COSMA U9 has been appreciated among
specialists for decades. The machine is set out perfectly
for economic continual operation.
The technically matured
construction results high production numbers with clean
cutting performance. The simple waiting of the machine
consists of inserting the raw blanks and gather the
finished staves. The roundtemplate always produces the
wished form of stave. There with the same template also
various stave lengths (by means of change gears as per
schedule) and diameters (by adjusting hand wheel with
Ø-index) can be attained. The machine has high pressure
lubrification and continuous oil bath in the gearing.
The automatically adjustable cutterhead in heavy ball
bearings has 3 cutterholders with 3 curved knives of
highalloyed implement steel. The particular cutter shape
allows at the same time scrubbing and smoothing for
each kind of timber. The cutting-Ø of the cutterhead
is automatically controlled by the template according
to the wished stave form.
The raw blanks are
centred exactly between two lateral entering jaws and
the upper and under fluted entering rolls, automatically
catched and guided into the cutterhead.
The combined swinging
smooth drawing rolls are adjusting themselves for the
curvature of bent staves. Straight staves are guided
in straight line. The drawing rolls have easily changeable
form-rings and are drawing the finished staves in safe
A worm gearing running in permanent oil bath drives
the precision rolls chain for the stave transport ans
well as the controlling template over change gears.
The gearing hand lever effectuates the automatic opening
of the entering guide.
The raw stave entered
up to the stop will be catched automatically and moulded
in correspondence with the shape of the round-template.
When the finished rod has leaved the machine, the entering
guide is automatically opened for the next working process.

By built-in electric
motor (5,5 KW, 2850 r.p.m) The consumption of power
is depending on the type of wood and the cutting feed.
- 1 set = 3
pieces of knives (or all Ø suitable)
- 1 round-remplate

- 1 pair of
drawingrolls for 1 wished stave diameter reach (graduated
from 5-5 mm)
- 1 set of change

(MP): Hereby quadrangular exactly cutted raw woods of
the same length can. be filled in adjustable pits. The
lowest piece is fed automatically into the entering
guide in the right moment and after this into the cutterhead.
The release is done by means of the round-template over
pneumatic valves and cylinders. Supposition for function
of the pneumatic fill-up magazine is an air compressor
of at least 6 atmospheric pressure and abt. 120 litres
absorbing capacity per minute. The magazine is adjustable
for various lengths.
Pneumatic Endsforming Device MEF:
It allows the fullautomatic
rounding-off (pointing) of ends of handle without any
time wasting (because done during the drawing process
of the machine). This device consists of an apparatus
guilt-on behind of the drawing guide, which carries
a horizontal carriage with set-on rounding head. The
already moulded stave coming out of the drawing guide
pushes to a pneumatic valve, by which the rounding head
of the MEF is elevated up to the height of the stave-passing-centre.
Then the stave if rounded-off automatically, the motor
with cutterhead hurries before, clatters again to the
bottom, so that the round-moulded and endformed stave
can slide over it and leaves the machine. The cutterhead
takes again the start position for forming the next
