Title:
SCARF SURFACE MACHINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/153651
Kind Code:
A1
Abstract:
[Problem] To realize a scarf surface which contributes to favorable bonding between scarf surfaces. [Solution] Using the following equation (1), a healing angle θ2 is adjusted to reach a desired camber h, and scarf surfaces 92a, 92b are machined on a veneer 90 with this healing angle θ2. This makes it possible to favorably prevent a second shaving of the veneer 90 by a circular saw 20. Note that the camber h is at the desired height, and thus it is possible to inhibit the scarf surfaces 92a, 92b from partially bonding with each other, while ensuring a space with which an adhesive Ad can be favorably held between circular arc concave surfaces 91, 91. This makes it possible to favorably inhibit the adhesive Ad from oozing out to the surface of the veneer 90 on the occasion of bonding the veneers 90 with the scarf surfaces 92a, 92b. As a result, it is possible to suitably bond the scarf surfaces 92a, 92b.
