(57) There is described an apparatus (2) for edge grinding of plate-like items, e.g. laminboards,
e.g. laminboards, comprising a carrying transom (4) displaceable in the longitudinal
direction, a trolley (12) with a turning ring (14) which is displaceable transversely
thereto, a roller conveyor (6) for stacks (8) of plate-like items, a fixing device
along the roller conveyor (6) for the said item stacks (8), and a programmable, preferably
combined electronic and pneumatic, control system, which apparatus comprises a number
of vertical carrying beams (16) suspended by the turning ring (14), and which are
mutually connected by means of a number of horizontal bushing pipes (18) in which
there are mounted sliding rod guides (20) for two vertical shafts (22) on which there
is mounted large number of grinding means rollers forming vertical grinding cylinders
(24) that preferably have greater length than height in comparison with the said item
stacks (8), and which are connected with each their driving motor, e.g. via driving
belt wheels and driving belts, so that said grinding cylinders (24) may rotate with
each their direction of rotation. In a simple way it hereby becomes possible to mechanize
the very heavy and work environment detrimental work connected with edge grinding
of plate-like items, e.g. stacked laminboards, which apparatus in addition makes possible
to optimise the grinding work itself.
