Method for producing a net, in particular for a basket for pisciculture

摘要

A net is particularly suitable for a basket for pisciculture, which may be placed in sea or fresh water. The net is made of a wire material, producible from individual spiral or similarly bent longitudinal elements, wherein adjacent threads are woven together. The net is simple and economical to produce, for example, by threading each longitudinal element into engagement with another longitudinal element while it has a shape of a spiral or screw to thereby provide it with a cylindrical form, and compressing each longitudinal element, when having the cylindrical form and after being threaded into engagement with the another longitudinal element, to provide the longitudinal element with substantially straight wire sections. The threading and compression steps are repeated to form a net after compression of several longitudinal elements threaded to one another.

1. A method for producing a net, comprising:
threading one of a plurality of longitudinal elements into engagement with another one of the plurality of longitudinal elements so that the one of the plurality of longitudinal elements is in contact with the another one of the plurality of longitudinal elements at a plurality of points separated from one another, each of the plurality of longitudinal elements having a first state in which the longitudinal element has a shape of a spiral or screw to thereby provide the longitudinal element with a cylindrical form in the first state, the one of the plurality of longitudinal elements being threaded to the another one of the plurality of longitudinal elements while the one of the plurality of longitudinal elements is in the first state in which the one of the plurality of longitudinal elements has the shape of a spiral or screw; then compressing the one of the plurality of longitudinal elements, when having the cylindrical form in the first state and after being threaded into engagement with the another one of the plurality of longitudinal elements, to bring the one of the plurality of longitudinal elements to a second state in which the one of the plurality of longitudinal elements has substantially straight wire sections, the step of compressing the one of the plurality of longitudinal elements comprising:
inserting the one of the plurality of longitudinal elements between two rows of stamps of a bending device such that the one of the plurality of longitudinal elements extends longitudinally alongside the two rows of stamps; and thenmoving the rows of stamps in a lateral direction of the one of the plurality of longitudinal elements toward one another; and then continuing the threading and compression steps by threading a first additional one of the plurality of longitudinal elements to the one of the plurality of longitudinal elements, then compressing the first additional one of the plurality of longitudinal elements, and so on to form a net after multiple threading and compression steps.
