Process for reducing the internal cross section of elastomeric tubing |
摘要 |
A hydraulic or pneumatically actuated muscle has an elongated elastomeric tubular bladder covered by a tubular braid. The bladder has a fold or invagination along its length. The process for forming this bladder can employ a fixture in the form of a threaded rod. A tubular elastomer is wrapped into the v-shaped thread on the rod. Then the wrapped rod is subjected to heat to set a fold into the tubing. The invaginate bladder can be subjected to a second, mild heat treatment to reduce curling.
