摘要： Procedure for separating heavy particles of material from lighter particles, e.g. for separating impurities from powdery or fragmental material, such as fibers or chips, in which procedure the material (2) to be treated is supplied onto a carrier surface (1) pervious to gas and gas impacts (P) are applied to the material through the carrier surface (1), causing the heavier particles to move closer to the carrier surface (1). The carrier surface (1) is mainly moved in one direction of movement to move the heavy particles (R) and the lighter particles (K) are passed, mainly by the agency of the inclination of the carrier surface (1) and/or the gas flow, in a direction substantially differing from the principal direction of movement of the carrier surface (1). The invention also relates to an apparatus implementing the procedure.

摘要： A wood chip shaver, consisting of cutting blades disposed on a circle and of a rotor rotating therewithin and carrying on its circumference vane-shaped chip guide members immediately adjacent to the blades, the members guide and press the chips against the blades. In front of the vane of the chip guide member is provided a guide surface approaching the blades in wedge-shape fashion in the travelling direction of the chips, the chips being carried in between the surface and the blades. With the aid the invention the chips are guided to enter between the chip guide members and the blades, whereby leaf-like chips such as are desired are obtained.

摘要： An apparatus for scattering fibrous material, e.g., chips or the like, to form a precisely controlled blanket of chips, together with a binder, onto a scattering band conveyor or a mold, includes a scattering chamber including a dosing conveyor for transferring the material to be scattered toward the discharge end of the scattering chamber. The apparatus is further implemented by arranging to the discharge end of the scattering chamber, next to the dosing conveyor, a roll set comprised of at least three rolls aligned mutually parallel, whereby slots of individually adjustable width are formed between the rolls.

摘要： A procedure and a means for correcting the transversal profile of a chip, fibre or equivalent mat being formed on a conveyor belt, said chip mat being formed with the aid of one or several rolls, most appropriately rake rolls, provided above the conveyor belt, in which procedure the free space for the chip mat between the last roll and the conveyor belt is adjusted transversally to the conveyor belt. In the procedure of the invention, substantially at the last roll the height level of the conveyor belt is raised and lowered stripwise transversally to the conveyor belt in order to regulate the transversal profile of the chip mat.

摘要： A method for limiting the dulling of wood-machining blades wherein the blades are insulated from the frame of a woodworking machine tool and a negative voltage is applied to the blades during operation. The blade ring of the chipper is insulated from the rotating rotor of the chipper so that between the blade ring and the rotor there is generated a differential voltage the rotor carrying a positive voltage and the blade ring a negative voltage. By virtue of the invention, the blades need not be replaced or sharpened as often as those of prior art chippers.

摘要： A blade ring for a shaver, consisting of blade units disposed in succession in ring configuration, within which a rotor rotates, urging the chips against the cutting blades. The blade units usually constitute a conical envelope, with a similar conical rotor within. The distance between the rotor and the blades is in means of prior art adjusted by shifting the rotor in axial direction, but this is difficult and requires complicated equipment. The blade ring of the invention is characterized in that each blade unit may be turned about an axis close to the cutting blade and parallelling the blade edge, for adjustment of the thickness of the shavings. By the aid of the invention, the thickness of the shavings can be regulated by simple adjustments.

摘要： A shaver for wood chips, consisting of a rotor provided with a chip guide plate and circumferential blades placed on its outside, in connection of which there is an annular interspace for the shavings cut from the chips, wherefrom the shavings further depart through a discharge aperture communicating with the interspace. At least one air passage is provided on the margin of the interspace and in the chip guide plate, through which the air flow created by the rotor can rejoin the circulation in the shaver. With the aid of the invention the air flow created by the rotor can be included in the internal circulation in the shaver and no large objectionable quantities of air depart from the shaver.
