ABSTRACT:
A stretch wrapping machine includes a web dispenser and a rotatable support for providing relative rotation between the web dispenser and load to wrap a web of packaging material around the load. Cooperating engagement members are selectively and positively engageable with each other throughout the rotation of the rotatable support for stopping the rotation of the rotatable support when the engagement members are positively engaged and for permitting rotation of the rotatable support when the engagement members are disengaged. One of the engagement members is mounted on a rotatable support and the other is mounted on a fixed support. An actuator selectively engages engagement members. One engagement member preferably includes at least two stop units spaced at a distance less than the distance between the engageable formations of the other engagement member. A shock absorber is connected to one of the engagement members for decelerating the rotatable support when stopping the rotation of the rotatable support when the engagement members are engaged.
