Abstract:
A method for fastening a tail of a wrapping of plastic film for a wrapped palletized load comprising the steps of:forming a pocket in at least one of final turns of a wrapping film of a wrapped load, said forming step including a longitudinal stretching of a portion of said at least one final turn causing said stretched portion to be arranged a predetermined distant from the wrapped load; holding the wrapping film, in a zone outside of the pocket at which a wrapping tail of the wrapping film will be formed, with a main clamp and a secondary clamp; cutting the wrapping film held between said main and secondary clamps so that the main clamp holds a film leading end for a wrapping cycle of a subsequent load, while the secondary clamp holds the wrapping tail of the wrapped load; inserting the secondary clamp holding the wrapping tail into said pocket after said cutting step; releasing of the wrapping tail by said secondary clamp inside said pocket; drawing said secondary clamp out of the pocket; and allowing the pocket containing the wrapping tail to shrink flat against the wrapped load so that the then shrunk pocket grips and firmly holds said wrapping tail.
