A substantially horizontal, flat shovel (30), made of thin, perforated metal plate, is integral with a slide (28) which is slidable on a guide (26), itself integral with a mounting (18). The shovel is driven by actuator means (20, 22, 24, 32, 34, 36) for moving forward and backward, while staying tangent to a facing rest shelf, at either of two speeds, a slow speed and a fast speed. The mounting (18) can move to different positions facing respective processing stations (42, 44).
