20090151817 | DEBARKING MECHANISM - The invention relates to a debarking mechanism ( | 06-18-2009 |
20100025191 | METHOD AND APPARATUS FOR PROCESSING LOGS - The present invention relates to a method of processing logs by means of an apparatus comprising a transportation level in the advancing direction (P) of the logs, where they are arranged to be transported in a position perpendicular to their advancing direction (P), and where orifice members going therethrough and extending in the advancing direction (P) of the logs. In the method, at least two support member units spaced from each other are arranged below the transportation level whereby each support member unit comprises at least one elongated support member, which is arranged rotatably parallel to the transportation level and perpendicular to the advancing direction (P) and protruding therefrom, and said axis of rotation of each support member unit is adapted so that when rotating, the support members protrude through the orifice members above the transportation level whereby the logs are received in one or more receiving spaces formed between the support members protruding above the transportation level. The invention also relates to an apparatus for implementing said method. | 02-04-2010 |
20110079492 | AN APPARATUS FOR RECLAIMING ROLLING MATERIAL FROM A PILE - The invention relates to an apparatus for reclaiming rolling material, such as e.g. wood chips, bark or corn from a pile ( | 04-07-2011 |
20110094857 | APPARATUS FOR STORING ROLLING MATERIAL IN A PILE AND RECLAIMING FROM THE PILE - The invention relates to an apparatus for stacking rolling material, such as e.g. wood chips, bark or grain into a pile ( | 04-28-2011 |
20110240783 | METHOD AND ARRANGEMENT FOR IMPROVING THE FIXING ARRANGEMENT OF A CHIPPER BLADE - A fixing arrangement of a chipper blade for a chipper having a cylindrical blade disc, one end surface of which is provided with one or more blades extending essentially radially in relation to the blade disc and for support thereof a wearing segment is arranged, the chipper is provided with a wearing surface subsequent the blade for resisting the stress caused by the logs being chipped in the chipper. At least one blade segment is arranged to be supported onto the blade and the wearing segment, an upper surface of which forms a desired portion of the wearing surface, and a coating is formed on the upper surface to resist stress. | 10-06-2011 |
20120024426 | DEBARKING MECHANISM AND METHOD - A debarking mechanism including of rotatable debarking shafts extending parallel to an advancing direction (A) of the logs to be fed therethrough, which are provided with teeth extending beyond the circumferential surface of the shaft. At least the uppermost debarking shaft is moved sideways towards the inner part of the debarking mechanism in such a way that each debarking shaft directs an impact effect on logs colliding with it and moved by the debarking shafts located in a lower position. The circumferential speed of the debarking shaft is selected to be the greater the higher the debarking shaft is positioned. A free passage is arranged for the bark passing over the debarking shaft. | 02-02-2012 |
20140166794 | BOTTOM GRATE OF A CRUSHER OR DRUM CHIPPER AND METHOD OF PRODUCING THE BOTTOM GRATE - A bottom grate for a crusher for chipping or comminuting material which includes: support ribs each substantially perpendicular to the rotational axis of the crusher; grate blades mounted to the support ribs and substantially parallel to the rotational axis, wherein the grate blades are releasably mounted to the support ribs and the grate blades each have a cutting edge proximate to a cutting or crushing rotor in the crusher; pulling members extending between two of the support members, wherein the pulling members are in tension and the tension in the pulling members binds the blades in the support members. | 06-19-2014 |
20150191317 | ROTARY FEEDER - A rotary feeder for transferring loose material, said rotary feeder having a housing, where a rotor transfers material from the feed channel of the housing into the discharge channel of the housing, the rotor having blades for transferring the material, and a counter blade is fixed in the housing of the rotary feeder between the blades of the rotor for cutting oversized pieces of material. A filler is arranged in the feed channel of the rotary feeder, to prevent the formation of a protrusion in the feed channel that would disturb the flow of the material formed by the counter blade, the edge of the filler adjacent to the counter blade being arranged to yield, and the filler is arranged to return to its initial position after the cutting operation. | 07-09-2015 |
