ABSTRACT:
A splicing device which can automatically connect films to a leader, includes a table for supporting the leader. The table has an opening over which is provided a support portion for supporting a film cartridge. A fixed guide and a movable guide are provided under the opening. Defined between the fixed and movable guides is a film turning passage having a film outlet and inlet that face the opening. A feed roller and a press roller are provided at the inlet of the film turning passage. With the leader set in position on the table, a swing arm is pivoted to catch the film end protruding from the film cartridge supported by the support portion. The swing arm is further pivoted to guide the film end through a second hole formed in the leader into the film turning passage. In this state, the feed roller is rotated to feed the film through the film turning passage and into the first hole formed in the leader while resiliently deforming prongs extending across the first hole. Then, the feed roller is reversed to pull the film backward until the prongs engage in holes formed in the film at its leading end. The film is thus connected to the leader.
