Abstract

A wire packet producing method using wire blanks including parallel first and second wire sections. The wire blanks includes bent transition/intermediate sections between the wire sections. The method includes withdrawing a first wire in the transition section length and a second wire section in a withdrawal direction. The first wire is straightened during withdrawal, forming a loop between the wire sections, offsetting the second wire section in an offset plane. The loop extends in the transition section region, providing a second wire withdrawing in the withdrawal direction. The second wire is straightened during withdrawal, guiding through the loop. The second wire is between the wire sections of the first wire, bending the second wire sections about a bending axis. The bending axis lies in the offset plane perpendicular to the withdrawal direction. The second wire sections are rolled about an axis parallel to the bending axis.

Dependent claims

A method for producing a wire packet for use in a wave winding mat, which wire packet is formed from at least a first wire blank bent in a U-shape and at least a second wire blank bent in a U-shape, wherein both wire blanks comprise a first wire section and a second wire section running parallel to the first wire section, wherein the first wire blank comprises a bent transition section between the first wire section and the second wire section, and wherein the second wire blank comprises a bent intermediate section between the first wire section and the second wire section, the method comprising:

providing at least a first wire from a wire supply;
withdrawing the first wire at least in a length of the transition section and the second wire section in a withdrawal direction, wherein the first wire is straightened during withdrawal;
forming a loop in a region between the first wire section and the second wire section;
moving the second wire section parallel to the withdrawal direction in an offset plane by at least two wire positions, whereby the transition section is formed between two bending points between the first wire section and the second wire section, wherein the loop extends in a region of the transition section;
providing at least a second wire from the wire supply;
withdrawing the second wire at least in a length of the second wire section in the withdrawal direction, wherein the second wire is straightened during withdrawal;
inserting the second wire into or guiding the second wire through the loop of the first wire, wherein the second wire is arranged in a wire position between the first wire section of the first wire and the second wire section of the first wire;
bending the second wire sections about a bending axis, wherein the bending takes place in the transition section of the first wire and in the intermediate section of the second wire and the bending axis lies in the offset plane and perpendicular to the withdrawal direction;
wherein the second wire sections are rolled about an axis parallel to the bending axis during the withdrawal and remain rolled during the moving and bending.
