Abstract

1371380 Ejectors L SCHULER GmbH 22 Dec 1971 [6 Jan 1971] 59558/71 Heading B3W In a punch press an insert 9 positioned below a die 7 has a throat 14 which tapers to a crosssection less than that of the die aperture so that perforated blanks 8, punched successively out of stock 6, which form a pile 10 in the insert, are dished at the tapered portion which breaks down the lubricant film on the blanks and allows the blanks to be ejected one at a time. A conveyer 11 carries the overlapping blanks to a stacking device 12. The tapered portion of the throat may be formed by inserts 16, Fig. 3, arranged in opposed pairs and which may be spring-loaded. To keep the blanks horizontal and to help individual ejection the lower end of the tapered portion of the throat is grooved at 13. Preferably the throat has an oppositely tapered portion 21 below the constricted portion.
