Abstract: The invention relates to a chipper knife for chippers of the type comprising a tool ( 12 ) which is rotatable on an axis of rotation and is in the form of, for example a drum, disc or truncated conical body, which supports a plurality of such chipper knives. The chipper knife comprises at least one cutting edge ( 1 ) which is formed between a flank ( 2, 2 ') and a chip guiding surface ( 4, 4 '), and two opposite main surfaces ( 3, 3 ') which are adapted to abut against and be retained on the opposite seats ( 14, 15 ) of a holder ( 9, 10 ) on the tool. At least one main surface ( 3, 3 ') of the chipper knife which is located on a wood side of the chipper knife comprises a cross-sectionally convexly bent surface portion ( 6, 5 ') which connects to and extends backwards from the flank ( 2, 2 ') and the chord of which constitutes at least 20%, preferably at least 30% and, most preferably, at least 40% of the total cross-sectional length of the chipper knife. The invention also relates to a holder for such a chipper knife.

Abstract: The invention relates to a multiple screw driving machine comprising a plurality of individual screwdrivers which are arranged on a body or in a housing ( 8 ) and which each comprise a spindle or shaft ( 7 ) which is rotatably mounted in the housing and which at an outer front end carries a screw driving tool ( 10 ) for engagement with a screw means. Each of the screwdrivers are separately drivable by a common motor ( 1 ) via a driving wheel transmission comprising a primary driving wheel ( 5 ) for each screwdriver. The primary driving wheel ( 5 ) is rotatably but non-displaceably mounted on the shaft ( 7 ) of the respective screwdrivers whereas a driver element ( 14 ) is non-rotatably but displaceably mounted on the shaft ( 7 ) and is displaceable with the aid of an operating means ( 16 ) towards and away from the primary driving wheel ( 5 ). The primary driving wheel ( 5 ) and the driver element ( 14 ) each have mating and mutually facing engagement means ( 19, 20 ).

Abstract: 13 The present invention relates to a processing means for barking machines of the type having a plurality of swinging arms (11), each being at an inner end pivotally mounted on a rotatable, annular rotator, while at an opposite outer free end, they carry such a processing means and are actuated by a spring load which strives to pivot the outer end inwards to the axis of rotation of the rotator. The processing means comprises a front (1), a rear (2), an upper (3) and a lower (4) surface, which are designed in such manner that an edge serving as a processing edge is defined between the front (1) and the upper (3) surface. The lower surface (4) is formed with an engaging means (8) which is adapted to engage a matching formation (14) in a seat (12) in the outer end of the swinging arm. The rear surface (2) acts as a supporting surface which serves to abut against a corresponding swinging arm supporting surface (16) which is directed forwards or obliquely forwards against the direction of feed of the logs. The engaging means comprises a ridge (8) or a groove and is rectilinear and elongate in such manner that its total length exceeds its height or depth, and preferably also its width, at least by a factor ten. The engaging means (8) further extends at an acute angle of at least 10.degree. in relation to the rear surface (2).

Abstract: A knife for a disk chip cutting machine which is mounted between a carrier part and a clamping part and which includes a chip breaking surface extending into an opening adjacent an outer surface of the carrier part. The chip breaking surface includes a concave portion which terminates in a rib which extends outwardly and downwardly with respect to an interface between the knife and the carrier part with the concave portion being oriented to direct cut chips in a direction away from the outer surface of the carrier part during use.
