Patent SE-502879-C2 (SE)
Inventor: ZHENG WENXIN
IPC: G02B7/00
Filed: 1994-06-16
Abstract: When splicing optical fibers (1, 1') by melt-fusioning in an electric arc (7), the electric arc (7) is started, in order to give the fiber splice a large strength, before the ends of the fibers (1, 1') have entered the arc (7) and before they have contacted each other. The arc (7) is in this stage switched on with a low intensity which is increased in the stage when the fiber ends are fusioned to each other. When the electric arc (7) is established having this low intensity and immediately before the contact of the end surfaces and the melt-fusioning, the fiber ends are finely aligned with each other in the lateral direction. It can be performed by means of the optical system and the control means which are provided in commercially available fiber welding apparatus, and the fine alignment will give the splice a low attenuation. For standard fibers of the single-mode type a welding current through the electrodes (5) of approximately 6.5 mA is suitable. <IMAGE>

Each board obtained in such a way is chamfered on the outer side, the chamfer serves as a standard of the direction of leveling. Two boards are obtained by a saw cut positioned near the pith, and essentially parallel to each external chamfered edge. A leveling saw cut is made on the most external part of the log, that is essentially parallel approximately diametrically to the opposite saw cuts, preferably at the same operation in which the log is sawn approximately by diametrically opposite saw cuts. Each block with leveling saw cuts is directed through at least a single double-circular saw, whose saw cuts are inclined relative to the main surface of the block, for example, through 30 deg. and pass essentially radially and symmetrically relative to the position of the pith. This operation is carried out twice with different inclinations of the double-circular saw. EFFECT: enhanced quality of lumber at a low labor content. 9 cl, 6 dwg
