Problems solved by technology

This binding method is used for the netting of small net cages in traditional offshore and inner bays. It has the characteristics of simple process, time saving and convenience. The binding method has problems such as low seam strength, uneven force on the net, easy deformation and damage of the net under wind and wave conditions, and loosening of the mesh reinforcement and the net.
The ability to resist wind and waves is poor. When encountering strong winds and big waves, the net is broken and the fish escape, causing serious economic losses. In addition, the net cage tends to be larger and the wind and wave resistance is improved. New requirements are also put forward for the netting of the net cage. The actual production There is an urgent need to improve the traditional binding process in order to meet the needs of the development of cage culture technology

Embodiment Construction

[0019] see Figure 1-Figure 8 , using the binding process of the present invention to make a Figure 8 The circular cage shown.

[0020] The mesh used in net clothing 1 is PA mesh, which is cut and cut by electric soldering iron. Sew the cut spare mesh vertically and horizontally on each side with 2-4 mesh binding (piping) 2, and tie it tightly with "double tack" 3 knots ( figure 1 , figure 2 ); the seaming process of the netting 1 is as follows: fasten the opposite binding edges or edges 2 of the two nettings 1 or every 20 mm with "double-tack knots" knots to form a large seam 5, binding the edges or edges There is no obvious gap after seaming of edge 2 ( Figure 5 , Figure 6 ). According to the cage net clothing size, some small net sheets are sewed together into 8 large main nets 1, two bottom nets 13 and a block net 9.

[0021] And then tie it with a special edge-gang process: sew the 2-4 mesh net 1 around the rope 4 (diameter 4-10mm) that is as long as the horizo...

Abstract

A technology for binding the netted appliance for culturing fish in deep sea includes such steps as cutting the netted fabric to needed shapes and sizes, sewing and binding with ropes, and features its additional edge-binding step. Its advantages include high strength, uniform stress, and not deforming or not being damaged by waves easily.

Description

technical field [0001] The invention belongs to the manufacturing technology of net cages for seawater culture, and specifically relates to a netting manufacturing process for net cages. Background technique [0002] The binding of traditional cage nets basically adopts the stitching and binding process of trawl nets and gillnet nets, that is, after the nets are cut, the nets are connected into net bags by the method of equal mesh stitching or equal mesh stitching; Li Gang (or known as mesh reinforcement) is installed with a longitudinal mesh interspersed method to connect with the net clothing. This binding method is used for the netting of small net cages in traditional offshore and inner bays. It has the characteristics of simple process, time saving and convenience. The binding method has problems such as low seam strength, uneven force on the net, easy deformation and damage of the net under wind and wave conditions, and loosening of the mesh reinfor...
