Abstract: A seat assembly machine that uses stanchion rods to install flexible covers on seat cushions characterized by the fact that the stanchion rods are slidably mounted via slides in an axis generally perpendicular to the stuffing or plunging axis such that the stanchion rods more closely follow the contour of the seat cushion. The present invention can be applied to either bottom seat cushion stuffers, back rest stuffers or neck cushion stuffers as desired. In the preferred embodiment the combination of a cam mechanism and spring mechanism controls sliding movement of the stanchion rods. The cam mechanism includes a cam track having an eccentric substantially matched closely to the contour of the intended seat cushion and a follower adapted to follow the eccentric.

Abstract: 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.
