ABSTRACT:
An apparatus for automatically taking up and depositing spools consists of a circular cylindrical body having several radially displaceable claws which can be operated by compressed air uniformly distributed over its cylindrical external surface, which claws are pushed outwards against the force of a spring stretched over the external circumference of the circular body, and axially displaceable, so-called holding down elements which are situated between the claws and under the bias tension of springs to push the mounted spool flange against the bent end of the claws.
