Abstract: A process for the production of spunbonded nonwoven (1) and a device for this purpose are shown, wherein a spinning mass (2) containing solvent is extruded through a plurality of nozzle holes of at least one spinneret (3) to form filaments (4) and the filaments (4) are drawn, in each case, in the extrusion direction, wherein the filaments (4) are deposited on a perforated conveying device (9) to form a spunbonded nonwoven (1) and, subsequently, are subjected to washing (10) for washing out the solvent from the filaments (4) and to hydroentanglement (11). So as to allow an inexpensive and efficient production of hydroentangled spunbonded nonwoven by means of the process, it is suggested that fresh water (12) is supplied to the hydroentanglement (11) and the waste water (13) from the hydroentanglement (11) is supplied to the washing (10) as wash water (14).

Abstract: A method for operating a confocal white light sensor on a coordinate measuring machine including a sensor carrier configured to couple a coordinate measurement sensor that is movable in a straight movement direction relative to a base of the coordinate measuring machine is provided. A confocal white light sensor is coupled to the sensor carrier and oriented in the straight movement direction toward a reference body. The sensor carrier and the reference body are moved relative to one another in the straight movement direction, and a measurement signal representing a distance between the confocal white light sensor and the reference body is generated at different movement positions. Information relating to a relationship between measurement signals of the confocal white light sensor and an actual distance of the white light sensor to a measurement object is obtained and a measurement value of the object distance is generated.

Abstract: A method and an apparatus for monitoring a bearing state of a probe or probe part of a coordinate measuring machine, wherein the apparatus comprises at least one evaluation device and at least one monitoring circuit. A probe-side bearing section is mountable on a measuring-machine-side bearing section via a plurality of bearing devices. The monitoring circuit comprises at least one subcircuit per bearing device. A variable dependent on a resistance of the monitoring circuit is determinable. A resistance value of the subcircuit in a closed state of the bearing device is different than a resistance value of the subcircuit in the open state of the bearing device. The monitoring circuit is designed in such a way that an open or closed bearing state of each bearing device is determinable depending on the variable dependent on the resistance of the monitoring circuit.

Abstract: A method for measuring the coordinates of workplaces on a coordinate-measuring device has a probe head including a probe and a probe sensor associated therewith. The method includes generating a probe signal when the probe contacts a workpiece. From this signal, dimensional values are determined that represent the position of the probe head when the workpiece is contacted. The probe head additionally includes an acceleration sensor generating an acceleration signal when the probe head accelerates, wherein the probe signal and the acceleration signal are fed to a control and analysis unit for analysis. This unit determines the dimensional values so that an analysis signal is determined by subtracting the probe signal and the acceleration signal from each other, and the dimensional values representing the position of the probe head when contacting the workpiece are determined only using the analysis signal.
