<p>A wrapping machine stretch head comprises a pair of tension rollers (44,46) having first ends mounted upon a base plate and second ends mounted within separate and independent brackets (64,70) such that the second ends of the tension rollers are not connected to each other and define an axially open space therebetween. In this manner, when wrapping film is to be threaded or routed between and around the tension rollers (44,46), the wrapping film is able to be inserted into the axially open space in an axially oriented mode. The rotary drive system for the tension rollers is also mounted upon the base plate and not within an upper frame member as is characteristic of conventional wrapping machine stretch heads.</p> |
