159WITH LOOP FORMING


DEFINITION

Classification: 352/159

(under the class definition) Subject matter including means to form a motion picture film strip into free standing loops upon actuation or upon loss of one of the loops through

malfunction.

(1) Note. A loop as included in this subclass constitutes a portion of the film strip placed in an untensioned manner between two drive elements which are relatively fixed, the portion of the film being longer than the straight line between the drive elements. This loop or buckled length of film minimizes drive variations from being transmitted by the film through tensional stresses.
