A flow rack unit for providing stock material units includes at least two rack bays and one control system. Each rack bay has a removal side and a storage side opposite the removal side and is configured to provide the stock material units in a respective bay level arranged next to one another starting in the direction of the storage side. A respective sensor arrangement of the control system is associated with each rack bay. Each sensor arrangement is arranged at the storage side of the associated rack bay and connected to a control unit of the control system via a common data line. The sensor arrangements each include an occupancy sensor configured as a distance sensor. Each occupancy sensor has a measurement zone that is aligned to measure a distance from a rearmost stock material unit stored in the associated rack bay and disposed closest to the occupancy sensor.

In a method of manufacturing an optical system that comprises at least one beam deflection unit, at least one diaphragm element, and at least one holder for fixing the beam deflection element and the diaphragm element in a predefined arrangement relative to one another, the beam deflection element and a screening element are provided. The beam deflection element and the screening element are fixed by means of the holder such that the actual arrangement of the screening element relative to the beam deflection element corresponds to the predefined arrangement of the diaphragm element relative to the beam deflection element. The beam deflection element is irradiated by the processing light beams such that after a deflection by the beam deflection element the processing light beams are incident on a functional zone of the screening element and change its optical properties by energy emission.

An optoelectronic sensing device detects two contrasting marks arranged next to each other along two reading tracks on a moving web. An optical head is arranged above each reading track. Each head has a lighting source and a lens, by means of which the contrast marks are imaged on an associated light receiver. Information from the contrast mark is obtained from the output signal of the light receiver. An adjustable connector joins two substantially identical optical heads to each other so that their respective lenses are arranged asymmetrically in the associated optical head and are situated in immediate proximity to each other, which permits adjustment of the device for the smallest possible track spacings.
