发明名称 Method of making a pillow
摘要 A pillow (10) has a filler comprised of a foam rubber core (16) around which is spirally wrapped a polyester fiber batting (28). Circular end walls (13) are formed by drawing together extensions of a tubular casing (12) after the filler has been thereinto inserted in a pre-compressed condition. A method of making the pillow comprises snugly fitting an end of the extended casing (12) over the small end of a tapered tube (33), placing the rolled core (16) and batting (28) into a plastic bag (34), pushing the bag (34) and filler through the large end of the tapered tube (33) into the extended casing, removing the casing (12) from the tapered tube (33), removing the bag from the free end of the casing (12), and then forming the casing end walls (13) by pulling and tying drawstrings (27).
