Braiding, winding or spiralling machine and method for operating same

A braiding, winding or spiraling machine configured to be operated according to a method for braiding, wrapping or respectively spiraling at least one elongate material strand made from at least one elongate material fiber around a strand-like material,

• wherein the at least one elongate material strand is rotationally fixed at least at one point to the strand-like material, the at least one elongate material strand is repeatedly guided around a longitudinal axis of the strand-like material, and the strand-like material is simultaneously moved in a same direction substantially along the longitudinal axis of the strand-like material such that the at least one elongate material strand takes on a shape of a coil looping around the strand-like material,
• wherein a diameter of a cross section of the strand-like material is measured substantially perpendicular to the longitudinal axis of the strand-like material, and a feed rate of the strand-like material and/or a rotational speed at which the at least one elongate material strand moves around the longitudinal axis of the strand-like material is controlled or regulated as a function of the diameter of the cross section of the strand-like material,
• wherein the braiding, winding or spiraling machine is also configured to repeatedly guide the at least one elongate material strand around the longitudinal axis of the strand-like material and simultaneously move the strand-like material in the same direction substantially along the longitudinal axis of the strand-like material, wherein a measuring apparatus determines the diameter of the cross section of the strand-like material substantially perpendicular to the longitudinal axis of the strand-like material, and a control or regulating apparatus controls or regulates a relative feed rate of the strand-like material, defined as a distance by which the strand-like material moves upon a complete revolution of the at least one elongate material strand around the longitudinal axis of the strand-like material subject to the diameter of the cross section of the strand-like material, and
• wherein the relative feed rate of the strand-like material is controlled or regulated as a function of the diameter of the cross section of the strand-like material such that a degree of coverage of the strand-like material by the at least one elongate material strand, defined as a ratio of a total surface area of all of the elongate material strands facing radially outward with respect to the strand-like material covering the strand-like material in a section of the strand-like material to a surface area of the strand-like material in the section, substantially corresponds to a predefined value.
