Claim:
1. An apparatus for x-ray examination of moving products, comprising: (a) a conveyor device with a conveying means on which a product to be irradiated rests in a movement plane, wherein the product is transported in at least one of the following manners: along a predetermined movement trajectory at a predetermined speed; in accordance with a predetermined time-dependent course of speed or position; rotated about a rotary axis that is substantially perpendicular to the movement plane, or any combination thereof; and (b) a radiation generating device, configured to generate an x-ray beam, positioned on one side of the conveying means, and having a detector device, positioned on the opposite side of the conveying means, (c) wherein the radiation generating device is configured to generate an x-ray beam widening in fanlike fashion beginning at an x-radiation source of the radiation generating device, wherein the x-ray beam has an upper and a lower marginal beam and passes through the product, (d) wherein the detector device detects the x-ray beam striking it and converts it into a signal, which is supplied to an evaluation and control unit, (e) wherein the lower marginal beam of the x-ray beam extends obliquely to the movement plane, and (f) wherein the x-radiation source is positioned in linearly displaceable fashion in a direction parallel to the direction of the lower marginal beam of the fanlike x-ray beam.
