ABSTRACT:
A frame comprising crossplates 8 and 13 coupled and spaced apart by coupling rods 10 (FIG. 2) faces, by the crossplates 8 and 13, opposite ends of aligned plunger pairs 7 and 16, there being a plurality of said pairs associated with respective openings, in which they are a close sliding fit, in a housing in which is a supply chamber 2 surmounted by a supply hopper 6. Reciprocation of the frame 8, 10, 13 causes movement of the plungers 7, 16 with there being a movement time lag between the plungers of the pair to provide, when within the supply chamber 2, a space between the confronting ends of said plungers 7, 16, for receiving material from the chamber 2 as an object 18 which can be ejected (e.g. by wire 21) when the said ends are outside the housing 1. This arrangement ensures consistency of shape of the product and of the location at which it engages from the device, facilitating subsequent treatment and/or handling thereof.
