Process for controllably separating framed working area from remainder of the membrane

摘要

Apparatus and a process for controllably separating a framed working area of a membrane from the remainder of the membrane is disclosed. The process includes tensioning an expanse of membrane material and fastening a support frame to the membrane to define a working portion of the same. A bondable polymeric material is applied to form a continuous border outward of the outer edge of the support frame. Additionally, the framed working area of the membrane is separated from the remainder of the membrane by cutting the membrane outward of the support frame.
