The cooling water tank 50 includes a rotating roller 60 that hooks and pulls the knitted resin 10 formed by cooling the filamentous molten resin in the cooling water tank 50.
The extruder 20 melts and kneads a thermoplastic resin at a predetermined temperature to form a molten resin, and extrudes the molten resin into a resin pool 30 at a predetermined extrusion speed.

The molding guide roller 40 causes cooling water to adhere to the molding guide roller 40 by positioning a part of the molding guide roller 40 in the cooling water. Due to the rotation, the cooling water is always attached to the cylindrical surface of the forming guide roller 40, so that the molten resin does not adhere to the forming guide roller 40. The surface of the molding guide roller 40 is preferably roughened so as to form a water film. The rough surface can be formed by, for example, sandblasting.

It is easy to form 10-knitted resin in which at least one of hardness, density, and form is partially different.
Further, for example, by supplying the molten resin to the first pool chamber 30HA from the plurality of supply pipes 34A1 and 34A2, the molten resin can be uniformly supplied to the entire first pool chamber 30HA. Therefore, the filamentous molten resin flowing down from the first pool chamber 30HA can be made uniform.

FIG. 20 shows a case where an upper resin pool 30G and a lower resin pool 30H are provided.
The upper resin pool 30G is partitioned by a partition plate 33 into a first pool chamber 30GA and a second pool chamber 30GB. A first extruder 20A is arranged in the first pool chamber 30GA, and a second extruder 20B is arranged in the second pool chamber 30GB.

Two supply pipes 34A and 34B are provided on the bottom surface of the first pool chamber 30GA. The supply pipe 34A guides the molten resin to the first pool chamber 30HA, and the supply pipe 34B supplies the molten resin to the third pool chamber 30HA. Lead to the pool room 30HC. A supply pipe 34C is provided on the bottom surface of the second pool chamber 30GB, and the supply pipe 34C guides the molten resin to the second pool chamber 30HB.
As shown in the present embodiment, the resin pools 30G and 30H are provided in a plurality of stages, and the filamentous molten resin flowing down from the resin pool 30H at the lowermost stage is cooled with cooling water to form the knitting resin 10. It is easy to form the knitting resin 10 in which at least one of the forms is partially different.

21 to 24 are conceptual diagrams showing the initial steps of the method for producing a knitting resin according to the embodiment of the present invention.

As shown in FIG. 21, at the start of manufacturing, the weight 80 is positioned below the molding guide roller 40. The upper surface of the weight 80 is preferably located above the water surface 51.
With the weight 80 positioned below the molding guide roller 40, the molten resin is extruded from the extruder 20 into the resin pool 30.
The molten resin extruded into the resin pool 30 flows down from the holes in the bottom surface 31 of the resin pool 30 as filamentous molten resin.
A part of the filamentous molten resin is guided to the cooling water tank 50 after reaching the molding guiding roller 40, and the remaining filamentous molten resin is guided to the cooling water tank 50 without reaching the molding guiding roller 40.
At this time, since the weight 80 exists, the filamentous molten resin adheres to the weight 80.

Next, as shown in FIG. 22, the weight 80 to which the filamentous molten resin is attached is submerged in the cooling water tank 50.
The weight 80 submerged in the cooling water tank 50 is moved as shown in FIGS. 6 and 7 by a guiding means (not shown).
After reaching the state of FIG. 22 or the state of FIG. 23, the rotating roller 60 is rotated. The first rotating roller 61 can draw it into the cooling water, and the second rotating roller 62 can suppress the floating from the cooling water.
After the state shown in FIG. 24, by continuously extruding the molten resin from the extruder 20, the filamentous molten resin flows down and becomes the knitting resin 10 and is continuously guided to the outside of the cooling water tank 50.
