postponed. Subsequently, the adjustment motor 182 is actuated to push the formation 1 "14 so far forward until the front end of the building is aligned with a position marker 190 mounted on the outer surface of the expander segments 158. In such a position, the outermost bobbin 1 is oriented Next, the expander actuator nut 180 is screwed inwardly to tightly engage the expander segments 158 against the surface of the axial port 115 of the expander assembly 168 Then expand the fluid motor 135 to extend the piston 138 and thus move the body 128 downwardly displacing the movable member 126 _? As shown in Figure 12 This displacement movement of the movable member 126 generates sufficient force to destroy the material bridges of the applied dividing line 116 substantially simultaneously, so that the applied winding body 1 <12 is separated from the structure 1 _e 14. When the bobbin 1 _Θ 12 is separated from the structure 1 _e 14, so the expander assembly is free to rotate on the shaft 144, so that the sheet metal strip contained in this bobbin 1 «12 are fed by unwinding a tool or other device can "
