Abstract
A joint for the ends of an elongated perforated film strip which is movable alongside an annularly closed guide path by a conveying means, wherein on the one end of the film strip corresponding in length substantially to that of said guide path a follower is secured which projects from the plane of the film, and wherein at the other end of said film strip a lock-in aperture is formed for free motion engagement of said follower. By reason of this free motion engagement, the film strip joint renders possible, within certain limits, to equalize length tolerances of the film strip, plus at the same time the automatic uncoupling of the film strip ends.
Claims6
A joint for connecting the ends of an elongated perforated film strip into a closed loop which is movable along an annular closed guide path by a conveying means, said joint being characterized in that on the one end of the film strip, corresponding in length substantially to that of said guide path, a follower is secured which projects substantially vertically from the plane of said film, and in that at the other end of said film strip a lock-in aperture is formed for the purpose of allowing free motion engagement of said follower with said aperture.
