Abstract: The invention provides a nozzle box for the heat treatment of veneering in a veneer dryer, where hot air is fed via nozzles on the side of the nozzle box disposed toward the veneering onto the surface of the passing veneering. The edges of the nozzle holes are bent in the direction toward the veneering, and they form funnel-shaped holes for the outflowing hot air. The funnel-shaped holes are recessed toward the inside of the nozzle box and are disposed in a region beat out inwardly and the beat out edges have an about circular cross-section. In addition, a bevel is provided to improve the guiding of the veneer sheets.

Abstract: Apparatus for separating joined-bricks includes a transport means for moving the joined-bricks and a separating means disposed along the transport means for separating the joined-bricks into two parts, the separating means including a pressure bar engageable with the joined-bricks and actuating means operatively connected to the pressure bar to effect actuation of the latter, the actuating means providing for synchronous movement of the pressure bar with the engaged joined-brick during the separation, whereby the joined-bricks are movable without interruption along the transport means during the separation.

Abstract: Apparatus for reeling sheet material on a roll includes first pivoting arms pivotably mounted for rotation about an axis coincident with the axis of the roll, second pivoting arms having one end portion pivotably mounted on the first pivoting arms, and chain pressing means suspended from the other end portion of the second pivoting arms, the first pivoting arms being pivotable between an inoperable position which permits the roll to be mounted or removed from the mounting means and an operable position in which the chain pressing means extends about the roll to contact the veneer sheet material on the roll and thereby facilitate reeling of the veneer sheet material on the roll. Endless band means are movable into a position to contact the veneer sheet material on the roll during the reeling operation to also facilitate reeling of the veneer sheet material on the roll.

Abstract: For separating green bricks arranged in a compact array of abutting rows, a separating device is operable to engage the leading row of the compact array and to hold the individual row between the separating device and a base as the remainder of the array is moved away, whereby the engaged individual rows are sequentially separated at spaced distances on the base.

Abstract: Disclosed apparatus sort unequally dimensioned veneer sections or other objects which are successively conveyed in a transit direction by a conveyor in parallel to their planes. A series of sensors are mounted at equal mutual distances across the conveyor in a row extending transversely to the transit direction and generate sensor signals in response to successively conveyed objects. The sensor signals are analyzed and the extents of the conveyed objects are tested on the basis of the analyzed sensor signals, preferably with the aid of predetermined nominal values. The conveyed objects are sorted in accordance with their tested extents.
