Description of the Related Art An elastic ring made of various elastomers such as vulcanized rubber or urethane rubber is used as a packing to be attached to a hermetically sealed portion of an aerosol container. As a method for producing such an elastic ring, A method of forming a tube from the above-mentioned elastomer in advance, and then cutting this tube into slices with a lathe type cutting device,
That is, the above-mentioned tube was fitted to a round bar-shaped mandrel, supported between the rotation center of the headstock and the dead center of the tailstock, and the rotation center was driven to move the tube together with the mandrel around the center axis. Rotate and at the same time feed the knife-like cutter on the tool post laterally to insert the cutting edge of the cutter into a rotating tube and cut into slices, and each time one ring is cut, the tool post is parallel to the central axis. A method is known in which longitudinal feed is applied to move the cutting position in the axial direction by a predetermined pitch.

問題があった。When the above tube is cut to a narrow width with a knife-shaped cutter, a circular elastic ring made of a string-shaped body having a rectangular cross section is obtained. The cut end faces of the tubes on both sides of the sandwich are re-adhered by the elasticity of the tube itself immediately after the passage of the knife, and the adhered end faces of the tube made of an adhesive elastomer are adhered to each other, so that the elasticity is separated from each other by the above cutting. Since the rings adhere to each other and form a block into the original tube shape, it is necessary to manually loosen them after the cutting work and separate them one by one. There was a problem that it was again blocked into various shapes during storage.

う問題があった。On the other hand, in a lathe or the like for cutting metal, a water-soluble or water-insoluble cutting agent is sprayed on the cutting tool itself or a contact start portion of the cutting tool to cool the work and the tool. However, similarly, when cutting the above-mentioned tube, it was attempted to inject the release agent on the side where the tube starts to contact the knife-shaped cutter, in other words, on the advance side of the cutter. However, the oil-based release agent cannot be used because the elastomer swells, and when the water-based release agent is used, the release agent is repelled by the surface of the elastomer tube and the cutter It was difficult to spread the above-mentioned mold release agent to the cut end surface due to. When the spray pressure is increased to force the release agent to spread, when a thin tube with a wall thickness of 1 to 3 mm is cut into a narrow width of 1 mm, a part of the tube is deformed by wind pressure. Then, there was a problem that the cutting width fluctuates and the accuracy is lowered.

状にブロック化することがない。Since the release agent is sprayed between the cut end faces 10a of the tube 10 on the mandrel 11, that is, the end faces 10a of the tubes 10 which are cut by the knife 12 and separated from each other to the left and right, The agent adheres to at least almost the entire area of the cut end surface 10a, and a part of the release agent is added to the tube 1.
It adheres to the outer and inner surfaces of zero. As the cutting progresses, the cut end faces 10a of the tubes once separated on both sides (front side and back side of the paper) of the knife 12 again adhere to each other due to the elasticity of the tube 10 itself, but the release agent adheres to the cut end faces 10a. Therefore, the left and right cut end surfaces 10a do not adhere to each other in a difficult-to-separate state, and the mandrel 11 is pulled out after the cutting is completed, and at the same time, the tube 10 is separated to obtain an elastic ring. Since at least the cut end surface of the obtained elastic ring, that is, the end surface perpendicular to the central axis is covered with the release agent, even if the elastic ring is put into any container, the elastic ring is bonded again. It does not block into various shapes.

The tube 10 and the ring vibrate on the lagging side of 2, and this vibration is transmitted to the leading side of the knife 12, so that the cutting width fluctuates and the accuracy decreases. If the amount of the release agent supplied is too small, the desired effect cannot be obtained. On the contrary, if the release agent is excessively large, the release agent that enters between the mandrel 11 and the tube 10 is increased, and the mandrel 11 is discharged. On the other hand, the tube 10 becomes slippery, the cutting width varies, and the accuracy decreases.

The average value was 6/100 mm, but the sample No. 2 in which the release agent supply amount and the air pressure were properly set had the average deviation reduced to about 2/3 of the sample 1. On the other hand, Sample No. 3 in which the amount of the release agent supplied was too large showed a tendency that the deviation became large because the tube slipped on the mandrel, and Sample No. 4 in which the air pressure was set excessively was The deviation became large due to the occurrence of vibration.

The total time of this loosening time and the time required for cutting (cycle time per tube), and 330 elastic rings (for 3 tubes) obtained were piled up straight in a pipe shape and a load of 1 kg was applied.

On the other hand, in Sample No. 2, when the tube is cut, the release agent adheres to the cut end faces, so that even if the cut end faces come in contact with each other, re-adhesion does not occur, and the loosening time is significantly reduced. The disentangling time and the cycle time were reduced to 1/6 or less and 1/2 or less of those of Sample No. 1, respectively, and there was no re-adhesion during storage.

ができる。As described above, according to the present invention, a tube made of an elastomer is fitted on a mandrel, and the cutting edge of a knife-like cutter is inserted into the tube while rotating the tube together with the mandrel around the center line. In the method for producing an elastic ring that cuts the tube into slices, since it is a method of spraying a release agent between the cut end faces of the tube immediately after being cut off by the knife-shaped cutter, an elastomeric cord-shaped body having a rectangular cross section is used. It is possible to easily obtain an elastic ring that is a circular ring that has an end surface that is perpendicular to the central axis line and is covered with a release agent. It is easy to loosen into individual pieces without handling and is easy to handle, and the width of the elastic ring varies depending on the setting of the spray pressure and spray amount. The small, it is possible to improve the accuracy.

The mold agent adheres to at least substantially the entire area of the cut end surface 10a, and a part of the mold agent adheres to the outer surface and the inner surface of the tube 10. As the cutting progresses, the cut end faces 10a of the tubes, which are once separated on both sides of the knife 12 (front side and back side of the paper surface), will be removed.
Although contact again by its own elasticity, since the cut end surface 10a adheres the releasing agent is not the cut end surface 10a of the left and right sticks into a difficult state separated and withdrawn mandrel 11 after slicing end At the same time, the tube 10 is separated to obtain an elastic ring. Since at least the cut end surface of the obtained elastic ring, that is, the end surface perpendicular to the central axis is covered with the release agent, even if the elastic ring is put into any container, the elastic ring is re- adhered. It does not block into various shapes.

Since this vibration is transmitted to the leading side of the knife 12, the cutting width <br/> fluctuates, accuracy decreases. If the amount of the release agent supplied is too small, the desired effect cannot be obtained. On the contrary, if the release agent is excessively large, the release agent that enters between the mandrel 11 and the tube 10 is increased, and the mandrel 11 is discharged. On the other hand, the tube 10 becomes slippery, the cutting width varies, and the accuracy decreases.
