A method and an apparatus for correcting a feeding distance of a strip or cutting, involves feeding the strip over the feeding distance in a feeding direction towards a cutting line that extends at an oblique cutting angle to the feeding direction; detecting a lateral position of a first longitudinal edge of the strip in a lateral direction perpendicular to the feeding direction; wherein, when the detected lateral position is offset over an offset distance in the lateral direction with respect to a reference position for the first longitudinal edge at the measuring line, and adjusting the feeding distance with a correction distance that is related to the offset distance in a ratio that is defined by the cutting angle.

The method for producing a strip of material with an integrated electronic component comprises the following steps according to the present invention: feeding a material web, cutting a first piece of material from the material web, lifting the first piece of material, applying an electronic component to the material web, once again feeding the material web with the electronic component located on it, cutting a piece of material from the material web to obtain a second piece of material on which the electronic component is located, and applying the first piece of material to the second piece of material so that the electronic component is accommodated between the first piece of material and the second piece of material.

A ply (16, 18) comprises metallic monofilaments (46′, 46″). Each monofilament (46′) of a first group has a positive torsional elastic deformation in a first direction about its main axis (G). Each monofilament (46″) of a second group has a negative torsional elastic deformation in a second direction about its main axis (G). The absolute value of the torsional elastic deformation C of each monofilament (46′, 46″) is such that |C|≤6 turns per ten metres. The mean S of the torsional elastic deformations of the monofilaments (46′, 46″) of the ply (16, 18) is such that −0.25 turn per ten metres≤S≤+0.25 turn per ten metres. The monofilaments (46′, 46″) are arranged next to one another so as to alternate one or more monofilaments (46′) of the first group with one or more monofilaments (46″) of the second group.
