ABSTRACT:
The invention relates to a variable-configuration head for seizing and handling objects, which head comprises a frame from which are suspended supports for seizing members through the medium of three links swivelled both to the supports and to the frame, the supports being geometrically equivalent to two identical articulated parallelograms having opposite angles at one common vertex, so as to allow the supports to be joined together transversely or longitudinally to modify the configuration of the group of objects held by the seizing members.
