Abstract: A rotatable stapler assembly for attachment to a machine for conducting a manufacturing step is provided. The stapler assembly includes a support bar, a stapler and an air cylinder assembly. The support bar has top and bottom arms and a middle portion which extends between the top and bottom arms. The bottom arm is designed to be rotatably attached to a machine such that the stapler assembly rotates about a longitudinal axis of the bottom arm. The stapler is attached to the middle portion. The air cylinder assembly is designed to extend between the machine and the top arm. In this manner, when the air cylinder assembly is activated, it rotates the support bar to place the stapler in the desired position relative to a work piece. When the stapler is in the proper position, it is activated to drive a staple into the work piece. When the air cylinder assembly is deactivated, the stapler returns to the start position.

Abstract: A machine and method for semi-automatically attaching casing to a structural frame assembly is provided. The machine includes a support frame assembly, a fixed bank of stapling units supported by the support frame assembly, a movable bank of stapling units slidably supported by the support frame assembly and oriented substantially parallel to the fixed bank, and a head bank of stapling units located at one end of the fixed and movable banks and also supported by the support frame assembly. Each bank of stapling units includes a pivot bar, stapling units attached to the pivot bar for stapling the casing to the structural frame assembly, and clamping assemblies attached to the pivot bar for positioning and clamping the casing adjacent the structural frame assembly. The fixed and movable banks include jamb locators which are positioned to engage and retain the longitudinal edges of the structural frame assembly.
