う問題があつた。 Conventional methods for manufacturing composite filament bodies by extrusion include inserting a billet in which the core material and outer layer material are integrated into a container into a container and extruding it, or supplying the core material into the extrusion chamber through nipples. , a method has been adopted in which an outer layer material is inserted into the container in the form of a billet and extruded to cover the outer periphery of the core material.
In all of these methods, the length of the product is limited by the capacity of the container, so there is a problem in that there is a limit to improving productivity and the quality of the extruded product also becomes uneven.

するものである。 In order to solve this problem, the inventors first focused on the conform extrusion method, which is an extrusion method using a rotation method, and found that it is possible to manufacture composite filaments of virtually infinite length with high efficiency and high quality. We proposed an extrusion manufacturing method that can be used. (For example, special request in 1970-
133186) This will be explained with reference to FIGS. 1 and 2, which are embodiment drawings according to the present invention. That is, in the extrusion manufacturing method described above, an endless groove 12 having a substantially U-shaped cross section is formed on the outer circumferential surface of a movable wheel that is rotationally driven by a drive shaft 11, and the groove 12 and the shovel block 13 that engage with the endless groove 12 are formed. Thus, a long and narrow transport passage 14 is formed, and an aluminum material 19, for example, which is to be the outer layer material, is supplied from one end of the passage 14, and the aluminum material is 19 is sent to the back of the passage 14, and the stopper 15 is arranged at the back of the passage 14, thereby forcibly preventing the movement of the aluminum material 19, thereby generating internal pressure in the aluminum material and forcing it into the passage. For example, a steel wire 21 to be a core material is guided into a gathering chamber 18 communicating with
is supplied, and the composite wire 22 is extruded from the die 16.

になりかねない。 According to this method, both the outer layer material and the core material can be supplied as having infinite lengths, so that the composite wire 22 as a product can also be obtained in a substantially infinite length form. However, the above method is not completely free from problems. That is, as understood from the extrusion pressure generation mechanism described above,
Since the pressure generation depends on the contact friction between the endless groove 14 and the material 19, if slip occurs between the inner surface of the groove and the material, the extrusion pressure is significantly reduced. If such pressure fluctuations occur many times for some reason, it will cause large fluctuations in the formation of the coating layer, leading to variations in wall thickness, uneven outer diameter, and other product defects. This could be the cause.

る。 In view of the above-mentioned circumstances, the present invention has been developed to provide a composite wire that can always stably form a homogeneous coating layer even if slips occur in the transportation path when extruding the composite wire using a rotating wheel. The present invention aims to provide a method for producing a strip by extrusion.
すなわち、本発明の要旨とするところは、回転

押出成形するに際し、芯材に前方張力を付加しつ
つ製品を押出すことにある。 That is, the gist of the present invention is to form a composite wire larger than the cross-sectional shape of the gathering chamber when extruding the composite wire using a rotating wheel, and to apply forward tension to the core material when extruding the composite wire. The purpose is to extrude the product.
以下に実施例に基いて説明する。 This will be explained below based on examples.

線２２の芯材２１には前方張力が付加される。 FIG. 1 is an explanatory cross-sectional view showing the manufacturing situation of the composite filament body according to the present invention, and FIG.
This shows a cross-sectional view of A′. The structure indicated by each symbol is as already explained. Therefore, in the present invention, the cross-sectional area of the gathering chamber is formed to be larger than the cross-sectional area of the cross-section X-X', and forward tension is applied to the core material 21 of the composite wire 22.

圧力変動を一層低減せしめる効果を有する。 As mentioned above, the cross-sectional area of the gathering room 18 is equal to the passage 14.
If the cross-sectional area is larger than the cross-sectional area, the volume of material per unit cross-sectional area will be much larger in the gathering room than in the passage. In this way, the extrusion pressure generated in the transport passage is accumulated in the collection chamber with a large volume, and even if there is a pressure fluctuation in the transport passage with a small volume, the influence of the fluctuation on the pressure fluctuation in the collection chamber is reduced. It is. A simple example of this principle is the principle of the backpipe of a musical instrument.Even if the air fluctuates greatly within the blowpipe, the pressure is stably accumulated within the backpipe, which has a large cross-sectional area.
On the blowout pipe side, the air flow can always maintain a stable constant flow. If you think of the transport passage as the blow pipe, the gathering room as the bag, and the blow pipe as the die, the effect will be clear. It should be noted that if the cross-section reduced portion 20 is formed at the entrance of the collection chamber, the narrowing effect thereof will have the effect of further reducing pressure fluctuations within the collection chamber.

のである。 In addition to the effect unique to the present invention of stabilizing the pressure at the die portion having such a gathering chamber with a large cross-sectional area, the present invention also provides a constant front tension in the core material covered by the outer layer material. It is an essential configuration requirement to add . By applying this forward tension, even if the pressure inside the collecting chamber fluctuates, a characteristic effect can be exhibited that can stabilize the thickness of the coating layer of the extruded product.

均一を生じ、製品不良につながる。 In other words, it is assumed that pressure fluctuations occur within the collection chamber while a constant forward tension is applied to the core material.
The fact that the pressure inside the gathering chamber is high means that the flow of the outer layer material at the die section becomes faster due to the internal pressure. If forward tension is not applied, the flow rate of the outer layer material will be faster than the extrusion speed of the composite wire, and as a result, the coating material will overflow from the die hole, resulting in the outer layer material being thicker than required. larger than the diameter. On the other hand, if the pressure in the gathering chamber becomes low, the flow of the outer layer material at the die portion is reduced, and as a result, the force that moves the composite wire itself outward is also reduced, and the thickness of the outer layer material becomes thinner. Thus, pressure fluctuations within the gathering chamber cause uneven thickness of the outer layer material, leading to product defects.

を防止するものである。 However, if forward tension is applied to the core material, even if the pressure in the collection chamber increases and the flow of the outer layer material at the die part becomes faster, the core material will be forced to flow faster due to the forward tension. On the other hand, when the pressure inside the gathering chamber becomes small, the forward tension has the effect of pulling out the outer layer material inside the gathering chamber along with the core material, and the above-mentioned decrease in wall thickness occurs. This is to prevent the phenomenon.

る。 As described above, the present invention not only has the effect that the cross-sectional area of the gathering chamber is increased to provide cushioning due to the mass effect, but also that pressure fluctuations in the transportation passage do not directly result in pressure fluctuations within the gathering chamber. Even if the pressure inside the collection chamber fluctuates, forward tension is applied to the core material, ensuring an extrusion speed that is compatible with the flow of the outer layer material, preventing variations in the thickness of the coating layer, This makes it possible to always produce stable, high-quality composite filaments.

As the movable wheel 31 rotates, the outer layer material 40 is moved to the back of the passage due to the frictional resistance of contact with the endless groove 32, and is forcibly prevented from moving by the stopper 35, so that the same extrusion pressure is applied as described above. is generated and sent into the collection chamber through the cross-sectional reduction section 36. Thus,
The core material 41 is supplied from the nipple 38 and the outer layer material 40

におよぼす意義はまことに大きなものがある。 As described above, according to the method of manufacturing a composite wire according to the present invention, since the cross-sectional area of the gathering chamber is configured to be larger than the cross-sectional area of the transport passage, pressure fluctuations due to slips etc. occur in the transport passage. However, the pressure fluctuation does not cause the pressure of the outer layer material accumulated in the collecting chamber with a large cross-sectional area to fluctuate, and it is possible to obtain a composite filament body having a stable coating layer, and also to apply forward tension. By using this method, even if there is a pressure fluctuation in the gathering chamber, it can be prevented from affecting the thickness of the coating layer, so it is possible to consistently produce high-quality composite filaments, and the conform extrusion method Coupled with the effect that products of infinite length can be obtained by application of this invention, the significance of the present invention to this industry is truly great.
