Blower type stretch wrapper module for coils
摘要:
A stretch wrap device for delivering stretch wrap film to a coil of cable or other filament type product being wound on a rotating mandrel and a traversing assembly for delivering stretch wrap film to the coil of cable or other filament type product; the traversing assembly including a stretch wrap module for traversing parallel to the rotating mandrel; the stretch wrap module including a motor and roller assembly for contacting and transporting the stretch wrap film toward the rotating mandrel so that an end of the stretch wrap film engages the coil of cable or other filament type product, and the continued rotation of the mandrel causing the end of the stretch wrap film to cover the surface of the wound coil of cable or other filament type material; the stretch wrap module also includes a compressed air generator and air jets for supporting the end of the stretch wrap film with compressed air, the end of the stretch wrap film engaging the coil of cable or other filament type with the completion of the winding of the coil of cable or other filament type product.
