Abstract
In a method for determining alignment of line formations of a web, a radiation source emitting radiation and a detector with numerous radiation sensors for sensing the radiation are provided. The radiation source and the detector are reciprocated together simultaneously transversely across the web. During reciprocation across the web, at least one measuring location of the web is irradiated by the radiation source and measured values, based on local radiation intensities are measured by the radiation sensors of the detector. The measured values are communicated to a computer. The computer generates, based on the measured values and the relative positions of the radiation sensors to one another, a local structural image of the at least one measuring location of the web.
