[Problems to be solved by the invention]
When decorating the peripheral edge of the floor mat manufactured by the conventional method 1, it is trimmed by sewing a thermoplastic elastomer tape or a cloth tape, or trimmed by sewing with an overlock sewing machine. It is the most widely implemented because a wide range of choices can be made. However, there is a problem that earth and sand and dust spill on the floor surface because the number of sewing steps is required and the peripheral decoration portion is lower than the flat portion at the center of the floor mat.
[0006]
On the other hand, the floor mat formed by the conventional method 2 is advantageous in that it does not require man-hours for decorating the peripheral portion by sewing or the like, and because the central plane portion is surrounded by a higher jetty portion, It has an excellent function of preventing earth and sand and dust from spilling onto the floor surface.
[0007]
However, as shown in FIG. 10, a surplus portion 26 is formed on the outside of the jetty portion 25 on the vulcanized floor mat 21, and the surplus portion 26 needs to be cut and removed using a punching blade 27 or the like. There is.
[0008]
In addition, the floor mat from which the surplus part has been cut and removed in this way is difficult to see because the side surface of the backing rubber or the carpet base cloth is visible on the cut surface, and such floor mats are often shunned when the appearance feels cheap. .
[0009]
SUMMARY OF THE INVENTION An object of the present invention is to eliminate a cutting step after vulcanization molding and to obtain a floor mat in which a cut section is not exposed at a peripheral portion.

Laminated and arranged between the upper mold and the lower mold, the upper mold convex part and the lower mold concave part are fitted to each other, and the carpet is disposed between the upper mold convex part and the cut part. Between the peripheral portion of the uncured rubber sheet and the peripheral portion of the unvulcanized rubber sheet, and pressing the upper convex portion against the cutting portion to cut off the peripheral portion of the carpet and the peripheral portion of the unvulcanized rubber sheet. Then, the present invention relates to a method of manufacturing a floor mat, wherein compression vulcanization molding is performed in a state where the surface of the carpet is in contact with the inner surface of the upper mold projection.
[0011]
Further, according to the present invention, the inner side surface of the upper mold convex portion is inclined outward, the inner side surface is brought into contact with the cutting portion, and the peripheral portion of the carpet and the peripheral portion of the unvulcanized rubber sheet. And a method of manufacturing a floor mat.
[0012]
Further, the present invention provides a floor mat, in which the inner surface of the upper mold projection and the inner surface of the lower mold recess are brought into surface contact, and the peripheral portion of the carpet and the peripheral portion of the unvulcanized rubber sheet are cut off. It relates to a manufacturing method of
[0013]
The present inventor made various floor mats on a trial basis and studied in order to eliminate the step of cutting the floor mat after vulcanization molding and to obtain a floor mat in which the cut section is not exposed at the periphery of the jetty.
[0014]
The present inventor studied a method of vulcanizing and molding a carpet and an unvulcanized rubber sheet using a floor mat molding die as shown in FIG. 1 in order to manufacture such a floor mat. FIG. 1 is a longitudinal sectional view of such a floor mat molding die. The molding die 1 includes an upper die 1a and a lower die 1b. The upper die 1a is provided with a projection 1d for biting outside the upper die ridge forming portion 1c, and the lower die 1b is provided with a lower die ridge forming portion 1e and a hole 1f for forming a non-slip protrusion. .
[0015]
In such a method, the periphery of the floor mat is formed by cutting the carpet and the rubber sheet by the biting protrusion 1d and vulcanizing the carpet. The floor mat molded in this way has advantages that it does not require man-hours for decorating the peripheral edge by sewing or the like, and because the central plane portion is surrounded by a higher jetty, It has an excellent function to prevent earth and sand and dust from spilling on the floor. In addition, this method also improves the unsightly appearance of the cut surface outside the jetty, which is a disadvantage of the conventional method 2.
[0016]
However, the present inventor has clarified that the surplus outside the jetty that could be removed by this method in many cases cannot be cut off by the upper mold projection. FIG. 2 is a partial longitudinal sectional view of a peripheral portion of the floor mat on which the uncut portion is formed.
[0017]
As shown in FIG. 2, in the floor mat 2, the surface carpet 3 and the backing rubber 4 are bonded to each other on the base fabric 3 a of the surface carpet 3, and the surface thereof is covered with a raised brush 3 b of the surface carpet 3. A flat portion 5 and a jetty 6 surrounding the flat portion 5 are formed.
[0018]
However, in this floor mat 2, a surplus portion 7 that is not cut off by the biting projection 1d is formed outside the jetty portion 6. Most of the remaining portion that has not been completely cut has not been cut. In order to prevent the cut surface from being exposed at the uncut portion, it is impossible to match a punching cutting blade 27 or the like as shown in FIG. 10 in an oblique direction shown by A in FIG. For this reason, it is necessary to cut and remove the hard outer peripheral portion in the A direction using scissors.
[0019]
As described above, the floor mat manufactured by such a method cannot completely cut off the surplus portion even if the jetty portion and the surplus portion can be partially separated from each other. In addition, it is necessary to cut off the surplus part with scissors or the like, and the backing rubber and the carpet base cloth on the cut surface are unsightly.
[0020]
The present inventor has further studied and found that the reason why the jetty portion and the surplus portion outside the jetty portion are not completely cut by such a method is that the base fabric of the carpet is hard to cut. As the base fabric of the carpet, a high-strength material such as a synthetic fiber non-woven fabric such as polyester is used to join the raised carpet and the vulcanized rubber sheet. Such a synthetic fiber nonwoven fabric is cut only by pressing from above at the time of vulcanization molding by using the surplus portion biting-off projection 1d as shown in FIG. is there.
[0021]
The present inventor has studied effective means for resection of the uncut portion based on such knowledge. As a result, the present inventor made the upper die and the lower die into a fitted state, and both the cutting pressure and the tearing pressure of the upper die and the lower die unvulcanized the outer periphery of the floor mat peripheral portion. As a result, the present inventors have found that the surplus portion outside the jetty portion can be completely cut off, and that the end surface of the peripheral portion can be covered with brushed carpet, thereby completing the present invention.
[0022]
According to the present invention, at the time of vulcanization molding of a floor mat, a base fabric of a carpet made of a synthetic fiber nonwoven fabric or the like, which is most difficult to cut off, is completely cut and separated at a peripheral portion of the floor mat before vulcanization. Further, in the present invention, the carpet base cloth and the unvulcanized rubber sheet are vulcanized and formed in a state where the carpet base cloth covers the surface and side surfaces of the unvulcanized rubber sheet at the ridge-shaped peripheral edge.
[0023]
According to the present invention, the jetty-like peripheral edge of the floor mat receives a compressive force during the compression vulcanization molding of the unvulcanized rubber sheet and is formed in a state of being separated from the remainder of the outer periphery, so that the vulcanization is performed. No cutting man-hours are required for the later floor mat, and the pier-shaped rim of the floor mat is molded in a state covered with carpet to the end face, the end face of the rim is covered with carpet napping, and the backing material is applied to the end face Is not exposed, so that there is no need for man-hours for providing a decorative peripheral portion after vulcanization molding, and a floor mat excellent in decorativeness of a jetty-like peripheral portion can be obtained.
