<p>The process for wrapping loads comprises the following steps: provide a covering sheet for wrapping a load; apply a certain pre-stretching elongation to the covering sheet; wind the pre-stretched covering sheet around the load; before and/or during the phase of application of the pre-stretching elongation, roll both longitudinal edges of the covering sheet up on themselves to form two opposite reinforcement borders. The system for wrapping loads comprises a wrapping head that has a first pre- stretching roller and a second pre-stretching roller for pre-stretching a covering sheet suitable for wrapping a load to wrap, the first and second roller being arranged upstream and downstream respectively in relation to the feeding direction of the covering sheet and the wrapping head comprising rolling up means for rolling up the covering sheet, which are located upstream and/or immediately downstream from the first roller and are suitable for rolling both longitudinal edges of the covering sheet up on themselves to form two opposite reinforcement borders.</p> |
