【発明の詳細な説明】 本発明はマット地の製造方法に関するものである。[Detailed description of the invention] The present invention relates to a method for producing a matte fabric.

でなくつまづいて転倒したりする危険があつた。In recent years, mat sheets such as artificial lawns, food-grade drainboards, and shoe-wiping mats have been manufactured from thermoplastic resins, but synthetic resins have a large expansion and contraction difference due to cold and heat, so the mat material may become wavy or shrink after being installed. Not only did it look bad, but there was a risk of tripping and falling.

うな現状に鑑み案出されたもので、以下図面にもとづき
ながら本発明の実施例について詳述する。In addition, since mats that are connected by joints are spread over a wide area, in the summer there is a significant difference in expansion and contraction between areas exposed to direct sunlight and areas in the shade, resulting in a wavy phenomenon. However, this expansion and contraction could not be fully absorbed, but the joints came off and there were wide undulations, making it difficult to walk on the facility. The present invention has been devised in view of the current situation, and embodiments of the present invention will be described in detail below with reference to the drawings.

数個の透孔５を設けるとともに側面にジョイント部４ａ
、４ｂを設けている。Reference numeral 1 denotes a substrate made of rubber, with a standing leg 2 protruding from the back side, a fitting part 3 such as a lawn area provided on the front side, and an arbitrary number of through holes 5 provided in the fitting part 3, and a side surface. joint part 4a
, 4b are provided.

６は、前記基板１の表面部と嵌合する金型で、針葉形状
等の凹部７を前記嵌合部３と対向すべく設けている。Reference numeral 6 denotes a mold that fits into the surface portion of the substrate 1, and has a concave portion 7 such as a needle-leaf shape so as to face the fitting portion 3.

８は、前記基板１の裏面部と嵌合する金型で、前記透孔
５と対向する位置に立脚用凹部９を設けている。Reference numeral 8 denotes a mold that fits into the back surface of the substrate 1, and has a standing leg recess 9 at a position facing the through hole 5.

基板１を加硫成型後、前記金型６、８て挾持したのち、
金型６の注入口１０より溶融した合成樹脂を射出し成形
するものてある。After the substrate 1 is vulcanized and molded, it is held between the molds 6 and 8, and then
There is a method in which molten synthetic resin is injected and molded through an injection port 10 of a mold 6.

ることとなる。In other words, in the case of the mat fabric formed by this method, since the substrate 1 is made of comb, it hardly expands or contracts due to cold or hot temperatures, so the joints become strained, and the mat fabric becomes wavy or comes off easily. This means that this phenomenon can be prevented.

保しう；るものとなる。Further, the substrate 1 is made of rubber and is flexible, making it comfortable to step on, but it is too flexible and difficult to maintain with only a standing leg. Therefore, in the method of the present invention, the injected molten resin flows out from the through hole 5 of the substrate 1 into the recess 9 of the mold 8 and forms a protrusion, and the synthetic resin functions as a standing leg, resulting in stability. It will also ensure that
