4.2.4 Gluing roller speed control (Fig. 4.8)
P2
Gluing roller H is aided by a temporary rotation movement.
This assistance is necessary for the edge to be perfectly glued
on the front part of the board, particularly on the first 2-3
mm. If you notice that the edge comes unglued on the front
H
end, you must increase the speed of gluing roller H by ope-
ning valve J on cylinder P2. To do this, you must first loosen
lock nut I on the valve. Likewise, if you notice that there is too
much glue being deposited on the front end, you must reduce
the speed of gluing roller H by closing valve J.
4.2.5 Cutting maneuver
The machine has the possibility of cutting the edge flush with
the panel or leaving an excess on the front or rear part by
means of a selector located on the rear of the machine. The
cutting maneuver with excess is designed for the edgeban-
ding of brittle edges (i.e. laminates) which can be splintered
by the impact of blades.
