Abstract: A cutting blade for a chipping machine, with the cutting blades being designed so that splitting blades extending at least essentially perpendicular to a cutting edge of the cutting blade are present, which project beyond the cutting edge and/or stand out from the cutting edge. The cutting blade consists of a blade support and a blade head, with the blade head corresponding with a friction fit to the blade support, and with the blade head being designed as a disposable component.

Abstract: A blade holder in a chipping device, has blade carriers that rotate in ongoing operation and blades attached to the blade carriers and being clamped in place with a clamping force via centrifugal forces that occur during rotation of the blade carriers in ongoing operation. The blades are attached to the blade carriers on a side that lies radially inward. There is at least one clamping element that lies radially inward of the blade carrier and is mounted on the blade carrier to rotate with the blade carrier. The clamping element exerts further clamping forces on the blade during rotation.

Abstract: A gluing device for gluing wood chips comprises a drum, a plurality of locally fixed discharge devices for glue being disposed inside the drum at least substantially along a line running parallel to a longitudinal axis of the drum, and shedding elements that shed the wood chips falling downward from above laterally relative to a line of the discharge devices. The shedding elements are present above the discharge devices. There are diverting elements, by means of which part of the wood chips falling downward are diverted while falling downward onto the line formed by the discharge devices, with these wood chips being guided between the discharge devices.

Abstract: A gluing device for gluing wood chips comprises a drum and a plurality of locally fixed discharge devices for glue disposed inside the drum at least substantially along a line running parallel to a longitudinal axis of the drum. There are support surfaces for the wood chips formed on an inner surface of the drum by noses directed at least substantially toward the longitudinal axis, the support surfaces differing in length or orientation relative to the longitudinal axis of the drum.

Abstract: A device for feeding wood chips to a processing unit, comprises a deflection surface in the device, that extends into a direct delivery path of the wood chips, a delivery unit for delivering air through at least one air admission opening in the deflection surface, and at least one air outlet opening in the device, the opening being positioned in the direction of air flow. The deflection surface ensures that the wood chips are held up at this point during the transport, so that the dwell time of the wood chips is extended. Because air is delivered through the deflection surface, the wood dust is swirled between the wood chips. This swirled wood dust is taken away along with the air blown in through the air outlet opening. This allows for a substantial reduction in the amount of wood dust in the wood chips during the further processing.
