ける単板削成工程の合理化を著しく阻害する要因
となつており、また原木の歩留りを著しく低下さ
せる要因ともなつていた。 With conventional rotary laces, there is a significant gap between the location where cutting resistance is generated and the location where the power required for cutting is supplied, resulting in frequent problems such as log destruction and blade clogging, which has led to problems in plywood factories. This has been a factor that significantly impedes the rationalization of the veneer cutting process, and has also been a factor that significantly reduces the yield of logs.

そこで本出願人は先に「ベニヤレース」（特開

ースを提案し、前記従来のロータリーレースの弊
害の払低を図つた。 Therefore, the present applicant previously proposed a new type of rotary lace in ``Veneer Lace'' (Japanese Unexamined Patent Publication No. 53-91499) in an attempt to eliminate the disadvantages of the conventional rotary lace.

弊害を払低して、極めて良好な切削を安定的に行
うことを可能化した効果は絶大であつた。 The most characteristic structure of this new type of rotary race is that it is equipped with a drive roll having a large number of blades on its outer periphery in a position where the blades can pierce the outer periphery of the log near the cutting edge of the cutting tool. The power required for cutting is supplied through the spindle, and if necessary, it is also possible to use the power supply from the spindle, but in any case, the position where the cutting resistance occurs and the cutting The effect of being as close as possible to the position where at least part of the power required for The effect was enormous.

る要因となつていた。 However, the veneer with puncture marks left by the blade of the drive roll has no practical problems for use as medium plates, for example, but it is not suitable for use in products that require relatively high quality, such as thin plates for surface use. This was not always a sufficient compatibility, and this was a factor that restricted the use of the new rotary race.

There is no need to apply torque, and it is possible to perform good cutting while suppressing the occurrence of wood destruction.
It is possible to improve the raw wood yield or productivity, etc.
In addition, since the power supply by the log drive device B is performed from the part of the log A that becomes the line scraps outside of the line drawing position, there is no risk of puncture marks remaining on the veneer S to be cut. , its versatility is extremely fulfilling.

タリーレースの他の実施例について次に説明す
る。 The log drive device, particularly the drive member, is preferably installed near the cutting edge of the planer stand, specifically, in a position where the blade of the drive member can pierce the outer circumference of the log near the cutting edge of the cutting tool. If installed in such a position, the path of power transmission becomes the shortest, effectively suppressing the destruction of logs, and also preventing the blade from clogging due to missing pieces of wood, which is extremely effective, but it is not always necessary. This is not intended to be limiting, and in any case, there are various other preferred embodiments, so other embodiments of the rotary race according to the first aspect of the present invention will be described next.

する必要がない点で至便である。 Another advantage of arranging the drive member near the blade opening of the planer stand is that the forward feed mechanism can be used as at least a part of the follower, thereby simplifying the configuration of the follower. As in the embodiment illustrated in FIG. 1 and FIG. 2, the driving member is provided so as to be able to move slightly near the cutting edge of the planer stand, and the stepping feed mechanism and the pressure mechanism attached to the driving member are connected to the driving member. If used in conjunction with a follow-up device to apply pressure to the outer surface of the raw wood, power can be supplied by the drive member at a relatively early stage, that is, before the raw wood becomes approximately cylindrical, making it possible to cut raw materials with irregular external shapes. Although it is effective, even if the drive member is fixedly provided near the cutting edge of the planer stand and the stepping feed mechanism is configured to also function as a follow-up device, if the raw wood becomes approximately cylindrical, the drive will fail. Since the power can be supplied by the member, there is no problem in practical use, and it is convenient in that there is no need to separately provide a follow-up device.

Even if the log drive device B is installed in a fixed member such as the bed/foam of the rotary race, or in a part other than the rotary race, there will be no impact on the ability to cut a log with an irregular external shape and follow changes in the outside diameter of the log due to cutting. No problem.

c is used as a driving member, it is possible to increase the number of piercings of the blade part 4 into the raw wood A as needed, thereby increasing the power supply capacity.
This is more effective than using a roll-shaped drive member, and, like the embodiment shown in FIG. 5, it is convenient in that there are no restrictions on the placement position of the log drive device B and the ability to follow the outer surface of the log. .

If the end face of the log A is perpendicular to the axis of the spindle 1, the tapered roll 5
There is no problem even if the is substantially fixed, but since there is no compensation that is necessarily perpendicular, a follower (not shown) is required.
The configuration of the roll is preferably such that the apex of the taper coincides with the axis of the spindle 1, as shown by the dotted line, and a speed difference between the blades at each piercing portion is unlikely to occur. is effective.

Relatively simple tuning means include, for example, a means of setting the power capacity of the log rotation device to be smaller than the power capacity of the drive mechanism of the log drive device, or a method of adjusting slippable members such as torque limiters and electromagnetic clutches to rotate the logs. Although means such as having the speed control mechanism built into the apparatus may be used, it is more accurate to use a tuning means in which the speed control mechanism is built into the log rotating device or the log driving device, as will be described later.
