The proceeding is the following:
On a cylinder disc
beared in a steady welded machine stand there sanding-belt-rolls
are fixed, over which two sanding belts are running
with high speed. The cylinder disc itself is rotating
hereby with 80 RPM.
There an automatic oppressing device is provided, that
always a good contact of the sanding-belts with the
rods of various diameters is guaranteed. So an optimal
sanding of the workspieces through the sanding belts
is attained by means of arms of levers and the centrifugal
force, whereby the sanding belts are pressed against
the workpieces in soft and elastic manner.
During the interval
between drawing of the finished and entering of the
new stave are regulating mechanism is adapting the minimal
distance of the circulating sanding belts (extra equipment).
Entering and Drawing
of the workpieces is arranged through rolls pairs. These
each are connected with a yoke, the pressure of the
rolls is increased at the entering side and of spring
pressure at the drawing side.
The drive of the rolls
is effectuated over belts and cogwheel gearing through
an electric motor with regulable speed of rotations.
