Abstract

PURPOSE: To facilitate position setting of lower rolls and to reduce time for recombination of rolls by fitting turning check arms to nuts of a roll shaft and making them movable along a guide shaft.
CONSTITUTION: A tube material 19 is sent in and formed by upper and lower rolls 3, 9, 9'. The upper roll 3 rotates with an upper roll shaft 4, and rollers alone rotate in the lower rolls 9, 9'. Nuts 11, 11' are connected with the turning check arms 17, 17' and rotation of the check arms 17, 17' is stopped by a guide shaft 18. The upper roll 3 is moved vertically by a motor 8 through reduction screws 6, 6'. The lower rolls 9, 9' are opened and closed by simultaneous movement of nuts 11, 11' incorporated in the lower rolls 9, 9' to opposite direction through rotation of the lower shaft 10 driven by a motor 13. By this way, setting of roll position is effected.
