Abstract

Abstract An apparatus and method for repressurizing hollow valveless articles such as tennis balls and the like in which an article to be repressurized is punctured by a needle having a passageway therethrough and both pressurized fluid for repressurizing the article and sealant for sealing the punctured and repressurized article are delivered sequentially and commonly through a single passageway of the needle. Provision is made for shielding the needle against exposure to undesirable accidental puncture and breakage and, by a particular cooperation of relative movement of an article and the needle, for avoiding removal of a plug of material from the article during puncture.
