Abstract:
1. A seat assembly machine comprising: a gripper that has two prongs retractably retained within a sleeve for gripping a piece of seat trim, the gripper including a pivot member between the prongs; and a control associated with the gripper for manipulating a position of the prongs between a closed position where the prongs are prevented from movement relative to each other by the sleeve, a released position where the prongs are separated from each other, and a neutral position where the prongs are biased toward each other and allowed to move relative to each other if the bias is overcome, wherein the sleeve comprises a channel having a contour that controls whether the prongs are in the neutral, closed or released position based on a location of the prongs relative to the sleeve wherein the contour comprises a tapering portion near an open end of the sleeve having a first interior dimension near the open end; a transition near an end of the tapering portion within the sleeve having a second, smaller interior dimension; and another portion further inward into the sleeve having a third interior dimension that is larger than the second interior dimension, wherein the pivot member is between the transition and the open end of the sleeve when the prongs are in the neutral position.
