ABSTRACT

A magnetic gripping apparatus, of the permanent magnet type, comprising a base
plate and peripheral walls, at least a first and a second pole units, each
pole unit comprising a main pole piece having an outer face defining a
gripping surface, main permanent magnets arranged between said main pole
pieces and said base plate, an intermediate pole member between said first and
second pole units, said intermediate pole member extending from the base plate
to the gripping surface and secondary magnets between the pole members and the
pole pieces; a first electrical windings encircles each main magnet, said
electrical winding being operatively conected to a control unit, and a
residual flux eliminating circuit comprising a second electrical winding
encircling said intermediate pole member, said second winding being
operatively connected to a demagnetizing control unit.
