Abstract

[Unintelligible text]

Claims (5)

1. The equipment for producing threaded rubber hoses consists of: a supporting frame; a rotating cylinder within the aforementioned supporting frame, which includes a passageway for feeding the rubber hose to expand in the axial direction of the cylinder; a first driving mechanism for rotating the cylinder; at least one screw placed within the cylinder, parallel to the feeding passageway; a second driving mechanism for rotating the screw; at least one hopper for feeding the screw with the threading material; and the injection end of the hose placed on the outlet side of the screw. The cylinder and screw rotate while the rubber hose is fed. 2. The instrument shown in claim 1, where the supporting structure described above is located with the feed casing, the cylinder described above is inserted through the feed casing, the feed casing described above is located with a circular passage to enclose the cylinder described above, and the feed passage is connected to the circular passage described above in the tangential direction of the circular passage described above; the cylinder described above consists of an open inlet at the circular passage described above; the threaded material described above is fed from the hopper described above through the feed passage described above, the circular passage and the inlet to the screw described above. 3. The instrument shown in claim 1 or 2, which arranges several of the aforementioned screws. 4. The instrumentation described in claim 3 arranges several of the aforementioned hoppers in conjunction with the screws to feed a different quantity of threaded material from the hoppers and screws in sequence. 5. The tool shown in claim 1 or 2 arranges several of the aforementioned screws; and arranges several of the aforementioned hoppers in the same manner as the aforementioned screws, in order to feed different quantities of threading material from the aforementioned hoppers to the aforementioned screws, respectively.
