Abstract

Improvements in the machines to square sheets or panels of wood, plastic material or the like, changed with multiple drills, characterized by comprising a fixed base that makes body with a frame which supports a support device of the sheet to be processed, consisting of a fixed longitudinal beam; and by a longitudinal beam of adjustable position with respect to the fixed beam and between which pneumatic means able to carry out the dam by means of suction cups have been located, working with depression on the underside of the sheet to be processed, which is supported on said device. Support and which remains immobile during the cutting of all four sides, the working group being sliding in longitudinal direction and comprising a pair of rotating saws, with work planes parallel to the vertical longitudinal plane of the machine and intended to work on the edges of the sheet protruding from the longitudinal flanks of the support frame and a second pair of rotating saws, with working planes vertical and perpendicular to the working planes of the preceding pair of saws, whose pair is mounted slidably on guide devices transverse, all the above mentioned rotating saws being associated with motors d and driving by firmly attaching two brackets to the uprights of the sliding frame, one for each upright, which, by means of rack axles, governed by a steering wheel and running vertically between guiding means incorporated into the brackets themselves, hold a drilling rod carrier of a series of tool-holder mandrels, driven by a motor mechanism, whose power take-off passes through at least one of the two terminal pierced bolts of the bar, whose pins are rotatable between supports and are provided, at least, one of a locking divider device.
