LASER CUTTING AND JOINING A FLUORINATED POLYMER MEMBRANE TO A POLYMER FRAME

摘要

Method and apparatus for cutting a fluorinated polymer membrane and simultaneously joining it to a polymer frame. The method comprising the step s of: (i) contacting a fluorinated polymer membrane with a polymer frame at th e point where a cut and join is desired, and (ii) directing at least one laser beam onto the point of contact between the membrane and the frame so as to c ut the membrane and effect a join to the frame.
