Therefore, there is a problem in that the wires constituting the side nets are rubbed and worn out.
  • the tension acting on the plurality of wires constituting the side network becomes non-uniform. Therefore, compared to the case where the load is supported on average, a larger burden is applied to some of the wires, and therefore the side net may be damaged early. Further, in order to prevent breakage, a side network having a larger wire diameter must be used, which increases costs.

Abstract

L'invention concerne une conserve de poisson (1) dans laquelle on empêche le filet de s'user par abrasion, et la tension qui agit sur le filet latéral est égalisée. La conserve de poisson (1) est pourvue: d'un cadre supérieur rectangulaire (10) disposé sur la surface de l'océan; d'une maille latérale (40), dont le bord supérieur est fixé au cadre supérieur (10), et qui a la forme d'une pyramide quadrangulaire tronquée; d'un cadre inférieur (30) qui est rectangulaire qui s'ajuste à l'intérieur du cadre supérieur (10) et qui est fixé au bord inférieur de la maille latérale (40); et une mèche inférieure (50) qui est étendue et disposée à l'intérieur du cadre inférieur (30). La maille latérale (40) est formée à partir d'une mèche qui est configurée par aménagement de plusieurs fils machines en parallèle et par liaison des fils machines contigus. De plus, la pluralité de fils machines, qui configure la mèche latérale (40), est disposée entre le cadre supérieur (10) et le cadre inférieur (30) de manière à être perpendiculaire au cadre supérieur (10) et au cadre inférieur (30).
