A method and apparatus is provided for turning a seat cover inside out. A pressure vessel (12) is fitted with a vacuum pump (16). The pressure vessel (12) is also provided with an inlet (20) which is fitted with a butterfly valve (22). The valve (22) is opened and closed by a pneumatic cylinder (39). Attached to the pressure vessel (12) around the valve (22) is a hood (26). The hood (26) has an open end (30) distal the attached end (28). A seat cover (32) is interfaced with the open end (30) of the hood (26). A vacuum is then created in the pressure vessel (12) and the valve (22) is opened. As the air from inside the seat cover (32) and the hood (26) is sucked into the pressure vessel (12), the seat cover (32) is also drawn into the hood (26). Since the pressure vessel (12) has a known volume of air removed and the hood (26) is of a known volume, the speed and/or amount of the seat cover (32) which is drawn into the hood (26) can be adjusted as desired.
