（例えば、特公昭60−50132号公報参照）。Recently, as a braiding machine for forming the reinforcing layer, a knitting device capable of forming a reinforcing layer rich in flexibility has been reconsidered with the diversification of hydraulic hoses and the like. An external rotation type (bobbin rotation type) nighting device is known as one type of the nighting device.
As shown in FIG. 2, the conceptual configuration of the nighting head 1 of the external rotating type knitting device is, as shown in FIG. 2, a knitting needle 9, which is displaceable only in the axial direction of the hose 16, around the hose 16 being extruded. , 9 are arranged, and the knitting needles 12, ..., 9 from the bobbin (not shown) are rotated in a fixed direction around the hose 16, while the knitting needles 9 ,. The knitted fabric 13 is knitted by advancing and retracting in the axial direction of the hose 16 while synchronizing with the operation, and the knitted fabric 13 is wound around the outer peripheral surface of the hose 16 to form a reinforcing layer. Here, the forward and backward movements of the knitting needles 9, ..., 9 are realized by the cam contact portions 10, ..., 10 of the knitting needles 9, ..., 9 being displaced according to the shape of the cam surface 8 of the rotating body 6. It On the other hand, conventionally, there is known a reinforcing hose manufacturing apparatus that forms inner pipe extrusion, formation of a spiral reinforcing layer on the outer peripheral surface of the inner pipe, and outer pipe extrusion on the reinforcing layer at substantially the same position at almost the same time (for example, (See Japanese Examined Patent Publication No. 60-50132).

の提供を課題とする。By the way, it is conceivable to incorporate an external rotation type knitting device into the above-mentioned reinforcing hose manufacturing device. In this case, however, it is necessary to make the knitting head of the knitting device compact for space reasons. However, if you try to simply compact the nighting head,
The diameter of the rotating body in the nighting head must be reduced, but the reduction in the diameter of the rotating body makes the forward and backward movements of the knitting needle unstable, and it becomes impossible to meet the demand for high-speed nighting. In view of the above problems, an object of the present invention is to provide a strengthening hose manufacturing apparatus incorporating a nighting device, which is capable of sufficiently satisfying the demand for high-speed nighting.

The knitting head 1 of this embodiment is a known reinforcing hose manufacturing apparatus including an inner pipe extruder 2, an outer pipe extruder 3 and a braiding machine 4, and the braiding machine 4 is used as a knitting device 4 for knitting. It relates to the nighting head 1 of the device 4. Here, the nighting device 4
Is interposed between the inner pipe extruder 2 and the outer pipe extruder 3 as in the known spiral device. The nighting head 1 has a substantially cylindrical base 5 fixed to the outer peripheral surface of the inner pipe die 2a of the inner pipe extruder 2 as a component. On the outer peripheral side of the base 5, a substantially cylindrical rotating body 6 rotated by a driving means (not shown) is rotatably mounted on the outer peripheral surface of the base 5 by a bearing 7 or the like. An annular and wavy cam surface 8 is formed on the circumferential surface side along the circumferential direction. Between the base 5 and the rotating body 6, a plurality of knitting needles 9, ...,
9 are provided. Each knitting needle 9 has a cam contact portion 10 that comes into contact with the cam surface 7. Each knitting needle 9 is arranged so as to be inclined so that the front end portion 9a is closer to the torpedo 2b of the inner tube extruder 2 than the rear end portion 9b, and is arranged so that it can be moved only in the axial direction by a spring 11 or the like. Has been done. Then, when the rotating body 6 is rotationally driven, the cam surface 8 is naturally
Also rotates in the circumferential direction, and the cam contact portions 10 of the plurality of knitting needles 9, ..., 9 reciprocate in the axial direction in accordance with the rotation of the cam surface 8 so that each knitting needle 9 moves forward and backward in the axial direction. Knitting yarn 12
The knitted fabric 13 is wound around the outer peripheral surface of the inner pipe 14. Then, the outer pipe 15 is formed by the outer pipe extruder 3 on the knitted fabric (reinforcing layer) 13 formed on the outer peripheral surface of the inner pipe 14 in this manner, and thereafter, necessary treatment (vulcanization treatment, etc.) is performed. ) Is applied to produce a reinforcing hose. As described above, according to the knitting head of this embodiment, the knitting needles 9 are tilted so that the leading ends 9a of the knitting needles 9 are closer to the torpedo 2b of the inner tube extruder 2 than the trailing ends 9b thereof are. Since it is arranged between the base 5 and the rotating body 6, the diameter of the cam surface 8 can be increased even if it is compact, and high-speed nutting can be sufficiently realized.
