ABSTRACT:
Apparatus for loading use tape (e.g. magnetic tape for video recording and playback) into leadered (e.g. V-zero) cassettes comprises a stationary splicing head 3 having an undersurface provided with a tape-receiving groove 4. A pair of vacuum shoes 5 and 6 serve to retain tape releasably in the groove and are connected to a vacuum source within the casing of the apparatus. A slitting head 7 operates from an internal pneumatic power source on shaft 9, the blade 8 of the head 7 running in a slot traversing the groove 4. In use, leader tape 20 is extracted from the cassette by leader extraction arm 18 and lift arm 19 and disposed in the groove 4. Slitting head 7 then operates to slit the tape into two lengths retained in groove 4. Use tape 26 previously placed in groove 4 and cut so that end 27 thereof is adjacent the groove for the blade 8 is sandwiched against the head 3 by the leader tape. Lift arm 19 and extract arm 18 then lower, the right hand end of the leader tape exposing the use tape in the groove. Splicing tape is then applied to the abutting ends of the use tape and leader tape and a winding cycle draws tape into the cassette until a predetermined length of use tape has been drawn onto the hub of the cassette. A similar slitting and splicing operation then takes place to complete the operations to produce a loaded cassette.
