Abstract

PURPOSE: To suppress the formation of end marks or eliminate it by combining the air cylinders of the respective wrapper units around a mandrel with elastically repulsing members cooperating with these and introducing the working pressure corresponding to the sheet steel pressing force.
CONSTITUTION: At the time of coiling a sheet steel on a mandrel 1, set pressing force aiF is supplied to each wrapper unit 2 and air cylinder 9 when sheet steel pressing force is determined from the steel kind, gage, etc. of the sheet steel. This causes oscillating frames 5 to advance until they receive the restriction by pulling bars 11, whereby the gap between a mandrel 1 and blocker rollers 8 is regulated. At this time, the pressing force of each unit 2 is maintained at predetermined set value together with the action of springs 12. On the other hand, the buffer pressure Fi' of the formula is applied by the action of springs 16, whereby proper buffer functions are given to the respective units. In the formula, (bi) is the own-weight correction value of the oscillating arms 7 on which the rollers 8 are pivotally mounted, and (c) is the correction value based on the correlation between the pressing force and the buffer pressure.
