Abstract
The present invention provides an apparatus and method of enclosing a vehicle seat elastomeric foam bun assembly with a prefitted cover. In a preferred embodiment the bun assembly is enclosed with a generally impermeable cylindrical bag having a lower coefficient of friction with the bun assembly foam than the coefficient of friction of the cover with the bun assembly foam. One end of the bag is connected with a vacuum source to sealably adhere the bag to the bun assembly and to connect the bun assembly. The bun assembly is then enclosed by the cover. The bag is then removed from between the cover and the bun assembly by ejecting the bun assembly out the open end of the bag while holding one end of the bag fixed.
