PURPOSE: To make it possible to perform several steps of pressing with less restriction on installation area, etc. and with good efficiency by disposing the stations for transfer-in, transfer-out and working of the works in a torus shape and providing a slide which can be moved vertically by an elevation-driving unit.
CONSTITUTION: A crown 3 and a head 2 are fixed by means 4 by way of a column 1 and during the ascending of a slide 5 (upper die) along the column 1, the blanks being the works and the finished products are transferred into and out from transfer- in, transfer-out paths 65, 67 from respective stations A, F. As the slide 5 descends, pressing is done in the respective stations AWF or BWE. During the next ascending of the slide, the works in each station are held by fingers 49 and are conveyed to the next by the forward revolution at a fixed angle θ of a feed bar 48. At this time, the above-mentioned transfer-in and transfer-out are accomplished, thence the pressing is done by the descending of the slide 5, at which time the bar 48 has returned to the home position.
