Seat assembly machine including selectively actuated screw for adjusting axes of the machine to assemble different sizes of seat covers on padded seat frames

A seat assembling machine commonly known as a skinner or stuffer is adjustable in several axes to allow the machine to be adjusted for different sizes/configurations of seats and seat covers. The machine includes a carriage which is driven towards a padded seat frame. The carriage includes a plurality of generally parallel stanchion rods that can be selectively spaced apart along two different perpendicular axes to receive a selected size of seat cover. The machine inserts a seat cover outside out over padded seat frames. The carriage may selectively rotated, selectively translated forward or horizontally and selectively tilted to better align the stanchion rods with the padded seat frame.
