Abstract
A rotary apparatus of a successive feed die unit of a press apparatus includes an indexing apparatus and a frictional transmission apparatus for transmitting rotation to a lower rotatable die of the die unit for manufacturing a core lamination assembly. The indexing apparatus converts rotation inputted from a crank shaft of a press apparatus into intermittent rotation of a predetermined angle and outputs it to the frictional transmission apparatus. The frictional transmission apparatus has a changeable rotation speed without steps, inputs the intermittent rotation from the indexing apparatus, adds rotational volume of a predetermined skew angle in a positive or negative direction to the inputted intermittent rotation, and transmits the total rotation to the lower rotatable die.
