A KNIFE CARRIAGE, A ROTARY VENEER LATHE HAVING THE SAME, AND A VENEER SLICER HAVING THE SAME
A nosebar is supported by supports arranged along the longitudinal direction, and the supports are assembled to fixtures to swing independently of each other in a direction away from a log according to the reaction force of the pressing force acting on the supports. Thus, when a knife peels a knot part of the log or a fragment of the log enters a cutting edge, the portion of the nosebar pressing the knot part or corresponding to the location where the fragment enters the cutting edge is greatly deformed, while the deformation of the nosebar in the other portions is kept small. A corner of the nosebar is prevented from contacting the peeled portion of the raw wood and generating a gap when the nosebar is bent and deformed.
EDGE BAND CUTTING DEVICE OF EDGE BANDING MACHINE
An edge band cutting device includes a base reciprocated along a direction parallel to a conveying path between a front cutting position and a rear cutting position, a baffle component disposed to the base and having a baffle configured to be reciprocated along a direction parallel to the conveying path between an initial position and a compression position, and reciprocated along a direction perpendicular to the conveying path between a lifting position and a lowering position, and a cutting component disposed to the base and having a saw blade configured to be reciprocated up and down along a cutting path perpendicular to the conveying path. By operation of the baffle component and the cutting component, only one saw blade is used to cut a front protrusion and a rear protrusion of an edge band, such that the structural design is greatly simplified.
Method and device for manufacturing a reinforcement for composite material made from natural fibers and reinforcement obtained using such a method
A method for making a fibrous strip configured for making a ribbon with a thickness ranging between 0.1 mm and 1 mm and a width ranging between 2 mm and 10 mm. The ligneous logs or cans are cut into square-edged plank with a predefined length. The strip is separated from a surface of the square-edged plank by an orthogonal cutting process. The depth of cut is equal to the thickness of the strip. The cutting speed direction is parallel to the fibers of the square-edged plank. Also, a fibrous reinforcement is obtained using the method and a device for implements the method.
