ABSTRACT:
Machine for front joining and sticking of oblong wood workpieces by toothed front joints and referential procedure consists of the flow press and entrance conveying line, and solves the problem of simple and quality front joining and sticking of workpieces, which travel through them fast and fluently in a consecutive row, irrespective of possible yet allowed curvature and dimensional deviation. This is enabled by the construction of entrance conveyors and exit conveyors of the conveying line, equipped with mechanisms for adjustment of side chain units, and with elastic couplings, whereby inside the side chain units the elastic insertions are placed, and inside pressing conveyors other elastic insertions are placed. Joints among individual entrance conveyors, among individual exit conveyors, and among conveyors are likewise elastic constructions by means of adjustable screws placed between fixed cantilevers, and between tension cantilevers. It is further enabled by the construction of entrance units and exit units in the flow press, or by the construction of pushing wheel pairs inside them, and which are simultaneously driven by the central driving coupling. For this purpose, each wheel pair is equipped with a pair of flexible cranks, the cylinder for pressure adjustment, the cylinder for position adjustment, the mechanism for interactive distance adjustment. Pushing wheel pairs also have the cylinder for the horizontal shift regulation and the shift-meter with which the force meter is connected, and which is placed at the end of the last pushing wheel pair.
