3.5 Feed rollers
The MP280 has five feed rollers, which feed the work pieces through the machine. Four
of these rollers are of ribbed metal and the last one has a rubber coating so that the sur-
face of the work piece will not be marked when it exits the machine.
The feed rollers are run by a separate motor with a planetary gear. The rubber roller goes
into the planetary gear. On the rubber roller there is a sprocket, which on its part runs the
other four feed rollers via chain transmission.
Adjusting the feed roller pressure
On each end of the feeding rollers, there is a spring mounted bearing housing. Under the
bearing housing there is a spring on a threaded bar. The pressure the feed rollers apply to
the work piece can be adjusted by turning the nut on the bottom of each threaded bar.
Ensure the pressure is the same at both ends of the feed rollers.
Lubricate the bearing housings of the feed rollers with oil after each work session.
The rubber roller should also be adjusted so that it applies just the right pressure to the
work piece. Remember that this feed roller should be set by the thickness the work piece
has when leaving the cutters.
IMPORTANT! Wood debris can accumulate under the feed roller
spring mounted bearings. This impairs the feeding and increases the
risk of the work piece being hurled out of the machine. Check these
areas and, if necessary, remove the wood debris that has accumulated
there.
Adjusting the feeding speed
The stepless feeding speed can be adjusted by turning the knob on the planetary gear. If
the knob is turned clockwise the feeding speed is increased; if it is turned anticlockwise
the feeding speed is lowered.
CAUTION! Do not adjust the feeding speed if the motor of the feed
rollers is not running. Equipment damage may occur.
The optimum feeding speed varies depending on what sort of wood you are machining,
the moisture content of the wood, and what type of moulding knives you have mounted in
the machine. The feeding speed can be adjusted from 2 m/min. to 12 m/min.
