Abstract: The invention relates to an apparatus for joining veneers, comprising a plurality of driven transporting rolls arranged along one axis, at least one counterpressure roll arranged parallel thereto, as well as heating means and pressing means. In order to achieve a simple construction and reliable operability the apparatus according to the present invention comprises a jacket of the transporting and pressing roll which is frictionally connected to a drive shaft by means of a slip clutch. This construction furthermore ensures the transportation and alignment of even very thin veneers with uneven longitudinal edges in such a way that the longitudinal edges can be aligned in a desired gluing direction in a direction transverse to the passage direction.

Abstract: A machine for processing plywood sheets which pass one behind the other includes a horizontal transporting and supporting roller, a cutter located above the roller and movable toward and away from the roller, a transporting device including a machine table and at least one transporting band rotatable about the machine table, and a testing device for rejecting defective plywood sheets or sheet portions, which has a plurality of testing rollers supported on pivotable parallel levers and is located above the machine table, so as to abut against the plywood sheets which are transported by the transporting device.

Abstract: In a machine for assembling veneer strips in transit on a machine table, said machine comprising conveying means, preferably driven conveyor discs, which are mounted in the machine frame and gather together the veneer strips by their butt edges, and said machine also comprising a feed device for supplying adhesive filament, such feed device applying an adhesive filament to the upper surface of the two veneer strips in an undulatory or zigzag manner over the butt edge region, the improvement comprising a spreading device, which coats the lateral longitudinal edges (butt edges) of the veneer strips with glue, disposed on the machine frame in front of the filament feed device when viewed in the conveying direction of the veneer strips, and at least one hot air nozzle disposed behind said spreading device in front of the filament feed device.

Abstract: Machine for assembling veneer strips comprising a reciprocating thread guide which is provided above a supporting table, a paper strip pasting device or the like which is arranged in front of a pressure roller rolling on the veneer strips along the connecting join thereof, comprising a device for conveying the veneer strips in opposite directions to a separating bar serving as a stop and extending vertically upwardly out of the table along the connecting join, and comprising a device for sealing the joins of the veneer strips by compression in which the thread guide and the pressure roller are arranged on a common carriage above the veneer strips, the carriage being displaceable parallel to the connecting join of the veneer strips, the separating bar being divided into individual separating elements which are arranged in a row at spaced intervals from each other and are lowerable in succession into the supporting table synchronously with the movement of the carriage.

Abstract: Device for packaging an object in foil wherein a pair of foils are disposed on both sides of a packaging plane and, in a central welding device, are welded to one another enclosing therebetween the object to be packaged, and wherein the foil webs travel in a given direction and, for each foil web, a foil-web parting and/or foil-web re-welding device is provided, serving to effect an exchange of foils and having functional members for parting a foil web as well as for welding a pair of juxtaposed foil-web ends together, the functional members extending transversely to the foil-web travel direction, the parting and/or re-welding device being disposed between a bearing which carries one foil roll, and a foil-web pullng device located upstream of the central welding device in the foil-web travel direction, includes at least another bearing carrying a foil roll disposed in spaced relationship to and behind the first-mentioned foil-roll bearing, means defining respective separate foil-web guide paths for the foil w
