  • Patent number: 7654385
    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.

  • Patent number: 6725891
    Abstract: Machine for profile working of front surfaces on oblong wood workpieces resolves the problem of simple, accurate and fluent or continued working of workpieces front surfaces of various lengths and intersections, and the machine is of a compact construction. It is characteristic by the construction of the entrance turnover device transversely placed between longitudinal conveyors with carriers, which has on the periphery of rotating wheels constructed movable bearing couplings, and by them fixed guiding plates with the groove inside which there are movably inserted guided bearings of bearing couplings. In the area of the entrance turnover device there are placed under an optional angle the oblique roller conveyors, inside which there are flexibly and circularly movably inserted rolls.

  • Patent number: 4964446
    Abstract: The invention relates to a machine for surface and thickness working of wood workpieces of any dimensions, in particular short and thin workpieces without rigid clamping of the workpiece, consisting of a machine housing, a movable working table, a two-part baseplate with circular cutout into which a face of a milling head provided with fixed and exchangeable cutting edges is inserted. In the head, there is a guide insert. An upper guide strip is disposed in exactly the same plane as the cutting edge apex on the milling head and also in the same plane as a stationary portion of the baseplate. At least two working spindles, set at predetermined angles, are provided. The workpiece slides on the two-part baseplate guided by two flank guide rails and an upper guide strip forming together a movement channel for the workpiece.
