<p>A trammel net (2) comprising an inner net (4) which is placed between wall meshes (6, 6'), and where the mesh size of the wall meshes (6, 6') is greater than the mesh size of the inner net. In the production of trammel nets (2), use is made of nets of different types, which during use shall be secured in a relatively well-defined mutual position while in use, which is done by mounting a head rope and a foot rope on the net. In the mounting of the trammel net, it is important to be able to secure wall meshes and inner net in a well-defined mutual position, and it is known to connect the wall meshes with an extra triangular mesh of mono-strand line, the object being to ease the positioning of the inner net between the wall meshes, and later the head and the foot ropes. The triangular mesh is of significance only in connection with the mounting, and it is provided that the line shall break immediately after the taking into use of the ready-mounted trammel net. The invnetion disclosed a method of producing a net of the kind described, which is characterised in that the wall meshes (6, 6') are drawn onto the edge mesh twine (10) of the inner net.</p> |
