Abstract

An inflatable packer is disclosed that includes inner and outer sleeves of elastomeric material. An annular sheath of overlapping reinforcing members is located between the sleeves. Each reinforcing member is bent adjacent each end to move a section adjacent each end into a plane that is parallel to and spaced from the center section of the reinforcing member. The members are bent at an angle that allows the members to overlap with their ends in alignment. The reinforcing members are mechanically clamped between inner and outer anchor members that form the packer heads.
