Abstract: For the fixing adjusting tools of the plate material to the structural body, the female member has a base plate with a through hole in a center and an external cylinder fixed vertically on the base plate. The male member has a base plate with a through hole in a center and an internal cylinder fixed vertically on the base plate. The communicating section is formed in the base of the female member communicating with the gap. The guide cylinder is formed protruding on the base plate of the male member to guide the nozzle for injecting adhesive. Resultantly, the adhesive injected through the guide cylinder into the rear surface of the base plate of the female member, reach the gap between the internal and external cylinders passing the communicating section.

Abstract: A tube forming mill, which consists of rolling mechanisms is mounted on movable trucks set or positioned on rails which are laid directionally crossing the material line flow at right angles thereto. The operation of the tube forming mill is as follows: While the rolling process is performed by one rolling mechanism, other rolling mechanism, which is to be used in the following process, is assembled onto the truck located at a position other than the unit rails which are on the material feeding line. After the last coil is passed through the rolling mechanism, the connector of the driving mechanism, which is disposed under the rails, is lowered to cut off the drive and the unit rails, together with the frame, are lifted by the elevating mechanism away from a fixing mechanism until the unit rails come up to the floor level.
