Stretch wrapping emergency stop

A process for quickly stopping rotation of a rotatable support relative a fixed support, wherein the rotatable support provides relative rotation between a web dispenser and a load to stretch wrap the load with a web of packaging material, the process comprising the steps of:

• engaging cooperating engagement members which are respectively located on the fixed support and the rotatable support so that the engagement members move together when in engagement;
• and
• decelerating the engagement members over a total absorption distance by a shock absorbing device operatively connected to one of the engagement members when the engagement members are engaged, thereby deflecting the rotatable support over a deflection distance relative to the engagement members when the engagement members engage so that the deflection distance incurred by the rotatable member reaches a maximum value at a distance less than the total absorption distance of the shock absorbing device, and the deflection distance incurred by the rotatable member approaches a minimum value when the total absorption distance of the shock absorbing device is reached.
