1.1 CHARACTERISTIC FEATURES OF THE MACHINE
In Figure 1 (page 2), we have provided the UNICO with the designa-
tions of the most important components. Please take a little time to
become with the machine.
1.2 DESCRIPTION OF THE MACHINE
The edge sanding machine UNICO works with a sanding disc wheel,
which is installed in an attachment. Three attachments in various
lengths can be supplied. The housing of the attachment covers the
actual working zone. A machine handle, which is used to guide the
machine when you are working on your knees, can be installed
depending on the length of the respective attachment. Velcro seal-
ing tape is used to seal off the working zone from the discharge of
dust. The resulting increased flow speed of the air upon entering
the working zone from outside guarantees constant good suction of
the sanding dust. Inside the attachment, there is a running V-belt,
which is driven via the V-belt pulley of the motor installed vertically
on the fan housing. The two guide rollers, which support the rear
of the machine, are also installed on the fan housing. In front, the
machine rests on the sanding abrasive (three-point support). The
fan housing is provided with two additional drilled holes into which
the machine handle can be screwed if and when required. On the
rear side of the fan housing, a rotating pipe bend fitted to a pipe
union conveys the sanding dust into the dust bag. The dust bag is
fastened to the pipe bend by means of a quick fastener.
The dust bag is suspended from the cable rod by means of a textile
loop. This textile loop keeps the connection cable away from the
working zone and is inserted in the holder on the pipe bend of the
machine guiding system. This holder also includes the Allen key,
which is required to replace conventional sanding discs. The pipe
bend can be used to guide the machine when you are working on
your knees. An extension including a handlebar is installed at the
front end of the pipe end and can be used to guide the machine
when you are working in a stooped position or in an upright posi-
tion. The extension and the handlebar can be adjusted as soon as
the clamping lever has been opened.
The machine guiding system and the switch box are attached to
the motor. An On/Off switch including no-volt release as well as
the rotating and swivelling working light is fitted to the upper side
of the switch box.
