Dense mesh type safe vertical net with double-layer edges and manufacturing method of dense mesh type safe vertical net

Abstract

The invention discloses a dense mesh type safety vertical net with double-layer edges. The edge part of square mesh cloth (1) is folded into double-layer mesh edges, a folded double-layer lining edge is placed between the double-layer mesh edges, and the edge part of the square mesh cloth is connected with the double-layer lining edge to form a mesh cloth double-layer edge (6); and a buffer edge rope (8) penetrates through a buffer rope mounting hole (7) between an upper-layer lining edge and a lower-layer lining edge. The invention further discloses a manufacturing method of the dense mesh type safe vertical net with the double-layer edges. The manufacturing method comprises the steps that firstly, the surface of the square net cloth (1) is coated with a PVC paste resin protection layer; secondly, lamp box cloth with a PVC paste resin coating serves as a connecting lining edge (13) to be placed on the edge of the square grid cloth; and thirdly, the buffer edge rope (8) penetrates into a buffer rope mounting hole (7) between the double layers of lining edges, and finally the edges of the folded square mesh (1) and the connecting lining edges (13) are heated and ironed at the high temperature of 250-350 DEG C to form mesh double-layer edges (6).

Description

technical field [0001] The invention relates to a dense-meshed safety vertical net with double-layer edges and a manufacturing method thereof. Background technique [0002] The net body of the current dense-mesh safety vertical net is processed into a double-layer net edge by a sewing machine. This processing method not only has relatively low processing efficiency, but also requires a sewing machine to sew each side of the net body. There will be seams, and long-term use will be damaged by weathering, which will shorten the service life of the dense-mesh safety vertical net. In addition, due to the small elasticity of the net body itself, the current net body is directly connected to the support, so it cannot fully withstand The impact force brought by the falling of heavy objects not only reduces the safety of the safety net, but also reduces the service life of the safety net. Contents of the invention [0003] The invention provides a dense-meshed safety vertical net ...

[0002] The net body of the current dense-mesh safety vertical net is processed into a double-layer net edge by a sewing machine. This processing method not only has relatively low processing efficiency, but also requires a sewing machine to sew each side of the net body. There will be seams, and it will be damaged by weathering after long-term use, which will shorten the service life of the dense-mesh safety vertical net. In addition, due to the small elasticity of the net body itself, the current net body is directly connected to the support, so it cannot fully withstand The impact force brought by the falling of heavy objects not only reduces the safety of the safety net, but also reduces the service life of the safety net.
