ABSTRACT:
A tapeless splicing system which allows the joining and separation of filmstrips without the use of tape. The system comprises forming an aperture (16, 26) in a leading end (12, 22) of a filmstrip (14, 20) and a tongue portion (28, 29, 30, 32, 34, 36) in a trailing end (24) thereof. The tongue portion (28, 29, 30, 32, 34, 36) of one filmstrip (20) is inserted through the aperture (16) of another filmstrip (12) by distortion as it is pushed through the aperture (16), the tongue portion (28, 29, 30, 32, 34, 36) and the aperture (16) being sized and shaped to provide effective interlocking between the two filmstrips (14, 20).
