to a suitable vacuum source not shown or to air under pressure through a line 74 also connected to a source of pressurized air not shown reference now should be made to fig7 through 10 taken in conjunction with fig1 a 11b and 12 for the operating sequence of the embodiment of the invention shown in fig5 and 6 as is apparent from an examination of fig5 the hollow support rods 63 which carry the ejector pads 31 on their lower ends are not attached to the plate 30 as was the case of the support rods 33 of the prior art embodiments of fig1 through 4 instead the rods 63 pass through holes or bushings in the plates 11 30 and 25 and are attached to and move with the plate 64 as described above consequently movement of the support rods 63 to the different positions of operation in the machine is dependent upon the movement of the plate 64 it should be noted however that when the plate 30 is lowered by means of the action of the air cylinders 27 to extend the rods 34 the plate 64 initially moves parallel to and in conjunction with the plate 30.
