Claims (1)

[Claims for Utility Model Registration] 1. A rotating roll having a contact surface on its circumferential surface and capable of driven rotation, the circumferential surface of which is connected to the front surface of a veneer veneer immediately after cutting, and from the cutting edge of a cutting blade to the raw wood. A groove-like portion extending in the circumferential direction is provided on the circumferential surface of the rotating roll, and is provided parallel to the cutting edge line of the veneer lace cutting blade at a position where it can contact both the outer periphery of the log on the upper side in the rotation direction. A plurality of strips are provided to form a contact surface on the outer peripheral surface divided in the axial direction, a nose bar piece serving as a fixed body is interposed in the space of the grooved portion of the rotating roll, and a nose bar piece serving as a fixed body is further provided. A guide member having a curved concave surface or an inclined surface that follows the circumferential surface of the rotating roll is integrally or integrally provided on the rake face, and between the lower circumferential surface of the rotating roll and the curved concave surface or inclined surface of the guide member. A discharge passage of the veneer veneer is formed, and the discharge passage of the veneer veneer is inclined outward in the direction of rotation of the rotary roll from a position close to the circumferential surface of the rotary roll at least near the end of the discharge passage of the veneer veneer, and has the curved shape. By providing an abutment member having an abutment surface that intersects with the extended surface of the concave or inclined surface, the veneer veneer sheet immediately after cutting, which is discharged along the lower peripheral surface of the rotary roll, is bent from the front side to the back side. A curl prevention device for a veneer veneer in a veneer lace. 2. A practical application in which the abutment member is interposed in a space in a groove-shaped portion of the rotating roll, and one end of the abutting surface is formed to be inclined from the inside of the groove-shaped portion to the outer side in the direction of rotation of the rotating roll. A curl prevention device for a veneer veneer in a veneer lace according to claim 1.
