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 |
