ABSTRACT:
Film splicing apparatus, for splicing together the ends of two films using an adhesive foil incorporating a tear-off strip and supported on carrier paper strips, comprises a base having a hinged lid and carrying a flat flap which is swingable through 180.degree. to an inverted position, which has therein a window which in an initial position of the flap receives a projection projecting upwardly from the base, and which has prongs for engagement thereon of the carrier paper strip, the flap carrying a pin which extends parallel to the swinging axis of the flap and traverses the window, there being a shoulder on the base, this shoulder providing a ledge extending parallel to the flap's swinging axis and an upstanding edge which is spaced from the swinging axis by a distance just slightly greater than half the length of the tear-off strip, the top of the shoulder being level with the bottom surface of a depression in the top of the base, and the upstanding edge providing an abutment surface which serves to cause erection of the free limb of the foil.
