(57) The machine comprises a unit (10) for extracting cages from a stacked supply including
two volute rollers (12, 13) which engage the bottom ring of each cage to cause an
axial displacement of the latter and means of transferring the extracted cages to
sockets (23) in a conveyor chain (24), comprising a plurality of buckets (21) subjected
to controlled motion components which halt each bucket (21) temporarily at the extraction
unit (10) to receive the cage and displace the bucket (21) in perpendicular alignment
with each socket (23) in the chain (24), the buckets (21) being then subjected to
the action of means (27, 33, 34, 35, 36, 37) which produce axial displacement serving
for picking up and respectively depositing the cages.
