Method of manufacturing and loading magnetic tape cassettes, particularly compact cassettes

Claim 1

A process for the manufacture of magnetic tape cassettes in an automated production line utilizing a movable support having accurately shaped and dimensioned recesses formed therein corresponding to the structure of one of said cassette halves for the receipt of the functional elements of the cassette assembly, such as tape guide elements, pressure pads, tape reels and magnetic tape, said process comprising the steps of: placing the functional elements of said cassette assembly in the corresponding recesses of said movable support by means of mechanical positioning devices; clipping the magnetic tape to a first tape reel positioned for rotation on said movable support in the plane of said functional elements; winding a predetermined length of magnetic tape on said first reel by rotating it at high speed; wrapping said wound magnetic tape about a predetermined path about said functional elements of said cassette assembly; clipping the free end of said wound magnetic tape to the second tape reel positioned on said movable support; positioning the inverted lower half of said cassette housing having recesses formed therein corresponding to said functional elements of the cassette assembly over the top of said movable support; rotating said movable support and positioned lower half of said cassette housing substantially 180° so that said movable support is located above said positioned lower half; raising said movable support from said lower half of said cassette housing thereby transferring said functional elements, including the wound magnetic tape pack and second reel to said lower cassette half; and placing the upper half of the cassette housing having recesses formed therein corresponding to said functional elements of the cassette assembly over said lower cassette half and fastening said cassette halves together.
