ABSTRACT:
This invention relates to an apparatus for stretching a textile material such that the magnitude of the strain at all points is equal in all directions in the plane of the specimen. The embodiment disclosed is an expandable circular pin frame. The pins mounted in puley are uniformly displaced radially outward and impart uniform radial strain without the edge effects associated with similar apparatus employing nonexpanding fastening mechanisms.
