ABSTRACT:
A leader section of a film strip having coupler holes in the leading section is inserted into a film guide concavity of a coupling table through a rear slot of a leader sheet placed on the coupling table. The film strip is continuously forced to slide along a curved surface of the film guide concavity until the front end of the leader section of the film strip passes through a front slot of the leader sheet. While the leader section moves through the front slot of the leader sheet, it pushes and bends the coupler tongues upward and lets the coupler tongues snap back and enter the coupler holes of the film strip to bring the coupler tongues into engagement with the coupler holes. Finally, by pulling back and stretching the film strip tight, the film strip is coupled to the leader sheet.
