In loading a carton with a coil of steel strapping for dispensing through a central circular aperture in the front wall of the carton, the carton is mounted on a mandrel which is received through the dispensing opening in the carton, the mandrel having a cylindrical winding surface disposed within the carton and having one or more radial slots therein. The leading end of a supply of steel strapping is fed through an open end of the carton and inserted into the slot and the mandrel is rotated for winding a coil of steel strapping thereon. The loaded carton is then removed from the mandrel. Retaining means are provided for holding the carton in place in its loading position on the mandrel so as to prevent rotation of the carton and bulging of the front and rear walls thereof during the winding operation.
A method of loading a coil of metal strapping into a dispensing carton having front and rear walls interconnected by a peripheral end wall, at least a portion of which end wall is foldable between open and closed conditions, the front wall having a circular dispensing opening therein centrally thereof, comprising the steps of:
Apparatus for loading a coil of metal strapping into a dispensing carton having front and rear walls interconnected by a peripheral end wall, at least a portion of which end wall is foldable between open and closed conditions, the front wall having a circular dispensing opening therein centrally thereof, said apparatus comprising a mandrel having a cylindrical winding surface with a diameter slightly less than that of the dispensing opening in the carton for passage therethrough to accommodate mounting of the carton on the mandrel in a loading position with the winding surface disposed within the carton and the one end wall open, said winding surface having a radial slot therein dimensioned to receive therein the leading end of a supply of steel strapping fed through the open end of the carton in its loading position, drive means for rotating said mandrel about the axis of said winding surface for winding the steel strapping into a coil thereon, and retaining means for holding the carton in its loading position during the winding of the steel strapping on said winding surface of said mandrel.
Apparatus for loading a coil of metal strapping into a dispensing carton having front and rear walls interconnected by a peripheral end wall, at least a portion of which end wall is foldable between open and closed conditions, the front wall having a circular dispensing opening therein centrally thereof, said apparatus comprising a mandrel having a cylindrical winding surface with a diameter slightly less than that of the dispensing opening in the carton for passage therethrough to accommodate mounting of the carton on the mandrel in a loading position with the winding surface disposed within the carton and the one end wall open, said winding surface having a radial slot therein dimensioned to receive therein the leading end of a supply of steel strapping fed through the open end of the carton in its loading position, drive means for rotating said mandrel about the axis of said winding surface for winding the steel strapping into a coil thereon, first retaining means engageable with the front wall of the carton in its loading position, and second retaining means movable between a retaining position engageable with the rear wall of the carton in its loading position for cooperation with said first retaining means to retain the carton therebetween and a release position out of engagement with the carton and accommodating movement of the carton to and from its loading position.
