Abstract
A link type transfer press is driven by continuously dwelling the slide in the vicinity of the top dead center thereof with the use of a link mechanism. With this arrangement, a motion index angle of a feeder can be taken by a large degree even though the time required for one cycle of the slide is shortened, and accordingly, the transfer time of the feeder can be set to be substantially longer so that the feed can be fed without interference with the slide. Thus, the entire pressing time can be reduced, thereby enhancing the productivity.
