Abstract: Disclosed is a protective hood for a wood-milling machine to cover a milling spindle which projects vertically out of a horizontal machine table. The protective hood is formed of two side walls connected to one another by a cover and a rear wall, and a front, vertically adjustable protective shield. The protective hood has a connection stub for an extraction device and can be attached adjustably to the machine table. A holding member for the removable attachment of a stop plate is releasably attached to each of the two side walls of the protective hood. In this way, the protective hood is permanently available as a basic element, so that when changing from curved milling to milling against a stop, it is easy to fit the stop plates.

Abstract: A wood chipping method and a disc chipper provided with knives (4). The chips (11), after having separated from a log (3), pass through a chip opening (12) in the disc (1) and hit an impact surface (10) located after a knife. Along different portions of the knife (4), a stronger impact effect is caused in proximity to the centre than in proximity to the outer periphery of the disc. The direction of the impact surface (10) deviates more from the direction of the rear surface (15) of the knife in proximity to the centre of the disc than in proximity to the outer periphery of the disc. The distance of the connecting line between the rear surface (15) of the knife and the impact surface (10) from the cutting edge (16) of the knife can be longer on the outer periphery of the disc than in the centre of the disc.

Heat transfer means (2, 2′, 2″, 2′″) are adapted to the stiffening rear portion of both the knife mounting beam (4) and the nose bar beam (5). Both the knife mounting beam (4) and the nose bar beam (5) have placed thereon, in a close vicinity to the knife (6) and the nose bar (7), at least one first set of temperature sensors (3, 3′) disposed in predetermined positions along the length of the knife and the nose bar.

Abstract: A roller for grasping a log for axial movement or rotation of a log, the roller including spike bar retainers fastened on the cylindrical surface of the roller. The spike bar retainers accept and retain replaceable spike bars, thus facilitating replacement of worn spikes, which may be replaced without removal of the roller. The spike bars formed of alloy steel feature an improved type of spike having planar side surfaces that converge to a pointed end. The improved spikes grip and hold logs at lower average pressures over an extended period of use than conventional conical spikes.

Abstract: A link type transfer press is driven by continuously dwelling the slide in the vicinity of the top dead center thereof with the use of a link mechanism. With this arrangement, a motion index angle of a feeder can be taken by a large degree even though the time required for one cycle of the slide is shortened, and accordingly, the transfer time of the feeder can be set to be substantially longer so that the feed can be fed without interference with the slide. Thus, the entire pressing time can be reduced, thereby enhancing the productivity.

The second lower rail is configured and arranged to be positioned above the router table along the lower longitudinal axis. The upper rail is configured and arranged to be attached to the router table above both the first lower rail and the second lower rail, whereby the upper rail defines an upper longitudinal axis that is substantially parallel to the lower longitudinal axis.

Abstract: An apparatus is adapted for discharging wood shavings that are generated during operation of a wood planing machine. The wood planing machine includes a machine base, a cutter support, a rotary cutter, and a drive unit. The apparatus includes a fan unit and a shavings collecting box. The fan unit includes a fan housing, a fan blade, and a drive shaft. The shavings collecting box has an open top disposed below a discharge hole in the cutter support so as to receive the wood shavings that fall therethrough, a closed bottom, and a lateral wall formed with an outlet port adjacent to the closed bottom. The rotation of the fan blade in the blade chamber causes the wood shavings that fall into the box to be drawn into the blade chamber via the outlet port and an inlet port in the fan housing and to be subsequently discharged through a discharge tube in the fan housing.
