(57) A new glue distributor assembly for edgebanding machine is described, wherein the
contacting roll, intended to roll on the panel edge to be edgeboarded, or on a finishing
profile for panels, is hollow and crossed by melted glue flowing from the collecting
chamber of the distributor assembly body. Preferably, within the contacting roll a
mixing element is inserted, pivotally with respect to the contacting roll, activable
to mixing the melted glue.
The distributor assembly is provided with adjusting squeegees of both the thickness
of the glue layer released on the outer surface of the contacting roll, and with a
height of the glue layer. The squeegees, acting as adjusting valves between the glue
collecting chamber and the contacting roll, have a flatting on the outer surface,
with a side corner and a higher corner and being pivotable and movable on the respective
longitudinal axes, parallel to the contacting roll.
The contacting roll is fixed to the body of the distributor assembly with pivots removable,
in order to allow the easy cleaning or replacing of the roll without acting on the
body of the distributor assembly, to disassembly or move it.
The outer surface of the contacting roll has a helicoidal profile making it self-cleaning
with respect to the solid particles detaching from the edgebonded panels and migrates
on the contacting roll and in the melted glue adherent to the contacting roll.
