发明名称 Coil breakaway device
摘要 Apparatus is described for separating individual coils from a construct of wound sheet metal web material that has been partially slit along parallel lines to produce parting lines containing frangible connections between adjacent coils. The apparatus is carriage-mounted and includes a mandrel assembly adapted to enter the construct center and carrying fluid operated means for anchoring the construct and for displacing the coil to be removed from the remainder of the construct thereby breaking the connections attaching adjacent coils thus to separate the selected coil from the construct.
