Abstract
A barking method, and an apparatus for utilization of the method, wherein a log (6) during a substantially linear feeding movement is brought to pass one or a number of barking devices (1; 4,4'), arranged to perform a surrounding rotary movement in relation to the log (6), the barking devices (1; 4, 4') are pressed into a contact position against the log by centrifugal force during the surrounding rotary movement in relation to the log, and the contact pressure of the barking devices (1; 4, 4') is continuously variable by increasing/decreasing the rotary speed of the barking devices (1; 4, 4') and the cutters are arranged inclined at an angle in relation to the feed direction of the log (6), to produce a feeding movement for the log (6) in a direction through the barking device (1; 4, 4').
Claims17
In a barking apparatus wherein a log is moved in a substantially linear feeding direction in the direction of its longitudinal axis through a barking means rotating around the log and urged into engagement with the periphery of the log by centrifugal force, the improvement comprising:
- a rotating member:
- an opening through said rotating member for receiving the log therethrough;
- at least one barking device movably mounted on said rotating member for rotation therewith and projecting into said opening for engagement with the peripheral surface of the log;
- centrifugal force operated means operatively connected to said at least one barking device for controlling the contacing pressure of said barking device against the peripheral surface of the log proportionally to the speed of rotation of said rotating member;
- and
- co-acting means operatively associated with said barking device to positively cause disengagement of said barking device at predetermined rotating speeds of said rotating member.
In a barking apparatus wherein a log is moved in a substantially linear feeding direction in the direction of its longitudinal axis through a barking means rotating around the log and urged into engagement with the periphery of the log by centrifugal force, the improvement comprising:
- a rotating member:
- an opening through said rotating member for receiving the log therethrough;
- at least one barking device movably mounted on said rotating member for rotation therewith and projecting into said opening for engagement with the peripheral surface of the log and comprising at least one sling shaped elongated rope-like member disposed in said opening of said rotating member and having opposite ends, and cutting means on said sling shaped member engageable with the peripheral surface of a log in said opening, said ends of said sling shaped member being connected to said at least two counterweights so that rotation of said rotating member rotates said sling shaped member and said counterweights and displaces said counterweights away from each other to apply a stretching force on said sling shaped member and engage said cutting means against the peripheral surface of a log disposed in said opening in said rotating member;
- and
- centrifugal force operated means operatively connected to said at least one barking device for controlling the contacting pressure of said barking device against the peripheral surface of the log proportionally to the speed of rotation of said rotating member and comprising at least two counterweights movably mounted on said rotation of said rotating member for linear displacement in opposite directions.
