ABSTRACT:
A cassette for storing and dispensing filamentary material to a machine for producing hollow articles by filament winding includes a housing having an outlet; a spindle supported internally of the housing; a hollow roll rotatably mounted on the spindle; and a reel of filamentary material carried by the hollow roll. The reel is fixed for rotation with the hollow roll and the hollow roll is rotatable in one direction to permit unwinding of the filamentary material from the reel. A force opposing the unwinding of the filamentary material is provided by a device located internally of the hollow roll. An adjustable braking mechanism is provided to establish a first tension on the filamentary material and an additional tensioning force is applied to the filamentary material by a complementary tensioning arrangement.
