Abstract

An apparatus for winding magnetic tape into a cassette positions and holds a cassette case, extracts and retains leader tape, cuts and splices leader tape to magnetic tape, and winds magnetic tape onto a hub inside the cassette. After a given amount of magnetic tape has been wound on that hub, the magnetic tape is retained, cut, spliced to leader tape, and the extracted slack tape is wound into the cassette case. Leader tape is extracted by extraction guides or rollers that move from a standby position within the cassette case front cavity to a position for winding magnetic tape. The magnetic tape winding position is such that leader tape, extracted to that position, is pulled away fron one of the cassette's internal tape guides, and during the magnetic tape winding process one extraction guide doubles as a tape tracking guide. Magnetic tape can be wound evenly, at high speeds and without damage by avoiding contact with the cassette's internal tape guide.

Claims2

Dependent claims

An apparatus for winding magnetic tape into a cassette having a rotatable hub therein around which hub leader tape is wound and to which leader tape the magnetic tape is attached and an internal tape guide over which tape guide the magnetic tape is guided to the hub once the magnetic tape is attached to the leader tape and wound into the cassette, said apparatus comprising:

extraction guide means for withdrawing leader tape from the cassette and for tracking and guiding the magnetic tape directly therefrom to the hub in the cassette after the magnetic tape is attached to the leader tape and during the time in which the magnetic tape is wound into the cassette;
and
movable frame means connected to said extraction guide means for moving the extraction guide means between a first standby position adjacent the leader tape of the cassette to a second winding position at which the leader tape is withdrawn from the cassette and displaced off of said internal tape guide so as to extend directly from said extraction guide means to the hub,
the magnetic tape after being attached to the leader tape when the extraction guide means is in the second winding position being wound directly onto the hub without contacting the internal tape guide as the hub is rotated.
