An apparatus for longitudinally orienting pre-glued elongated wood strands for forming OSB panels includes a spreading head with disc rolls that each have discs arranged parallel to one another on a rotatable shaft arranged over a forming belt. The discs of a given disc roll intermesh overlappingly in the interspaces between the discs of the adjacent disc rolls, to form vertical orienting passages between the intermeshing discs. The shaft or the individual discs of at least one of the disc rolls is/are slidably adjustable in the axial direction of the shaft, to adjust the axial width of the orienting passages. In a method of operating the apparatus, the width of the orienting passages is adjusted depending on the dimensions, the dimensional variation or tolerance, and/or the throughput quantity of the supplied strand material. Thereby, the throughput quantity and the longitudinal orienting of the strands can be optimized, depending on the particular strand material.

Adjustable disc roll for longitudinally orienting elongated wood chips

A device for the orientation of chips into a preferred direction during production of particleboard includes parallel vertical guide surfaces arranged at a distance from one another and horizontal parallel rotating shafts arranged at a distance from one another above the guide surfaces. Each shaft has spacer rings and pin plates that collectively provide pin roller arrangements for the orientation of chips in a preferred direction as the shafts rotate. Chips are discharged without congestion between the guide surfaces and without damage to the pins of the pin rollers. Free passage is also possible for chips to be oriented in the production of OSB boards.

Device for orientation of chips

Simultaneous removal from a multi-level press of all press trays carrying particle board panels is achieved with a press unloading installation. Such installation consists of a vertically movable press unloader cage having chain conveyor pairs, primary supports for the press trays and panels, and auxiliary supports for the trays alone after separation from the panels. The installation further includes a discharge device for removing the press trays from the auxiliary supports of the unloader cage. In order to shorten the return transport of flexible press trays, separation between the finished pressed particle board panels and the flexible press trays is accomplished in the press unloader cage.
