Abstract
An inflatable packer includes an elastomeric tubular body adapted for radial expansion and having a longitudinal axis. An elastic outer cover surrounds the tubular body, and coupling members are disposed on each end of the tubular body. A plurality of reinforcing elements are sandwiched between the cover and the body and have end portions terminating at the coupling members. The reinforcement elements include spirally wound members extending the length of said body between the coupling members. The reinforcement elements are wrapped about the tubular body in a manner to continuously decrease the lay angle thereof relative to the longitudinal axis of the body from each coupling member toward the center portion of the tubular body.
