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. The truck, together with the rolling mechanism, is moved out of the rolling process line and the following truck, with a new rolling mechanism to be used in the next rolling process, is advanced to location of the unit rails. The new truck is made to rest on the fixing mechanism by reversing the above procedure; the connector is lifted to bring the vertical drive shaft of the rolling mechanism into engagement with the drive mechanism and thereby rotate the rolls to perform the next rolling process.
