• the rings 4 to 4C should be completely cut to leave the conventional ones. Therefore, according to the law, when leaving the company, there is no separation (cutting) work, only 3a separation work, and only simple work remains.
• the edge cutting work between the ring locks can be done only by stroking several 3a mounted along the broken line in the direction. As a result, the working time can be greatly reduced.

• This 3 is about 0 to 7 in the direction.
• So 5 so that the ring 4 upper ring ring 4B connection is connected to these rings. It is effective to use a variable type that has a structure in which one or both of them move horizontally.
• variable type 3 is located between the plackets 2 so that even if the rig pack is displaced, it is possible to continue moving in the horizontal direction, or allow horizontal movement. It is preferable to use something that can be done. For example, a wire that can withstand heavy weight is preferable, and the latter is preferable.
• variable type 3 is preferably constructed on the bracket side so that it can be handled in the case of horizontal movement, or a racket that can be worn or removed. Below is a pair of rackets It is preferable that the interval is between. However, since the connection 3 used in the body process is only for holding a book, it is not necessary to adjust the connection, so the variable type is unnecessary. Use is possible.

In this state, the rig 4A and the upper rig 4B are connected via the connection 3 and are held together at 3a. 22 As shown in 2, the rig 4 supported by 3a and the upper ring book 4B are renewed, and in the meantime, the next lower book 4C is inserted. Supported by another suspension 3b.

• Ring book Lower level Can be easily combined with ring book
• a new reactor may be installed in the following manner.
• Ngu books 25 is an example when the number of Ngu books is 3 to 4A B 4.

• 26 a is an example of the variable type 3 and has a pair of racks, a parallel connection structure by combining with 1 2 connection () 3 a, and 26 b) uses a wire as the connection Wai Clap
• Reference numeral 26 shows an example of continuation by a type of wai clamp device in which the wire is held by the clamp racket and the wire is tightened.
• Ring book 4 4 by various 3 including this variable type, 4 is just a temporary contact (), it is only to support the rig 4 B of the part from the connection part The key is not necessary. It is possible to end within these periods. This means that the construction period can be significantly reduced compared to the previous 20 years. 20 Traditionally, furnaces have been conducted continuously day and night with dozens of workers around the iron. On the other hand, the law improves the ability to do normal work, which no longer requires this work. In addition, if the solder and guts 4 are aligned with the 5 cores of the Song, then it will only need to be aligned with these cores one after another. To do.
