In FIG. 1, reference numeral 1 denotes a tension member, and a spacer 7 is formed on the outer periphery of the tension member 1 by extrusion molding. At the same time, a plurality of grooves 4 are formed in the spacer 7 in a spiral shape. Fiber 2 is inserted.

じる。In conventional spacer-type optical fiber cable manufacturing equipment, the grooves 4 of the spacer 7 are provided by a rotating die of an extruder, so if the dimensions of the grooves 4 exceed 3 m in width x 31 rIIR in depth, the weight of the ribs 3 will be reduced during the cooling process. and rib 3
Due to the difference in the cooling rate of the materials near the tension member 1, the ribs 3 collapse and the grooves 4 collapse, resulting in a mismatch in the twisting pitch. Therefore, in order to secure the groove 4 in one direction, it is necessary to increase the outer diameter of the spacer 7, leading to an increase in cost. Furthermore, the groove pitch A is 300 mm.
Below this, the ribs will fall due to rotation, and the width of the groove 4 will become narrower. Therefore, when the cable is bent, the characteristics will deteriorate and the allowable radius will become larger. Furthermore, when forming spacer grooves using an extruder, irregular rotation of the rotating die of the extruder causes irregularities in the pitch of the spacer grooves, resulting in overlapping or the like when the fiber 2 is inserted.

The object of the present invention is to provide an optical fiber cable manufacturing apparatus that can be downsized and significantly reduce the number of work steps.

You can get 7 ig4. Rotary cutter 25 of groove cutting device 15
The installation f1'l position is shown in Figure 2. If it is attached to the front part of the sea urchin picking caterpillar 16, when the cutting edge of the cutter 25 is hooked on the spacer IJ7, a great tension is applied to the spacer 7, which is preferable. Also,
The co-rotating cutters 25 are arranged in stages 1 and 5, and the tension is prevented from becoming extremely strong by gradually cutting deeply.
1. The rotary cutter 25 and guide 35 are mounted on the pole bearing 33.

Inner diameter of mm human diameter. The mounting cage 22 of the groove cutting device 15 also removes the bobbin 23 of the optical fiber 2 because the groove pitch of the spacer 41 and the fiber insertion pitch are the same.
17- As described above, the optical fiber coupler manufacturing apparatus of this embodiment forms and covers the grooves of the spacer through the cutter, so the full 11 pitch and groove pitch X1 method can be freely selected. 1, 1, 1, 1, 1, 2, 1, 2, 1, 2, 1, 2, 1, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 1, 1, 2, and the outer diameter is small, so the full pitch can be reduced at low cost. Therefore, the bending properties are improved and the allowable bending radius can be reduced.In addition, the iν1 forming force is
The bobbin for supplying the optical fiber inserted into fM is removed (J
