Abstract: Toothed belt drive with a toothed belt and at least two toothed pulleys, wherein the toothed belt has at least one drive side provided with a toothed profile, the toothed belt wraps around the toothed pulleys over a partial area of their circumference and the teeth of the toothed belt meshingly engage in the tooth gaps of the toothed pulleys, wherein at least one of the toothings on the belt or pulley is formed as a series of tooth pitches varying along the circumference, wherein the individual tooth pitches are designed to vary by up to a maximum of 5% relative to the mean tooth pitch on the belt or pulley, and the absolute deviation of a varied tooth pitch from the mean tooth pitch on the belt or pulley is limited by the backlash of the toothing, wherein the backlash ES results from the difference of the width eS of the tooth gaps of the respective toothed pulley and the width eR of the teeth of the toothed belt in the middle of the tooth height of the teeth of the toothed belt.

Abstract: The invention relates to a method for sealing a reduction assembly, wherein the reduction assembly has a product discharge device, wherein the product discharge device is supplied with sealing gas and wherein at least one compressor is provided for delivering prepared sealing gas to the product discharge device, wherein according to the invention, at least one nitrogen generator is provided for producing pure sealing gas, and wherein the sealing gas for supplying to the product discharge device is composed of pure sealing gas from the at least one nitrogen generator or composed of pure sealing gas from the at least one nitrogen generator and of prepared sealing gas from the at least one compressor. The invention also relates to a device with which the method according to the invention is carried out.

Abstract: A device for cleaning adhesive surfaces of vehicle components using solid carbon dioxide is provided. The device may be used for automated cleaning in an assembly line with a plurality of work stations. The device includes a chamber-type cleaning area for vehicle components, a blasting device with a jet nozzle for emitting solid carbon dioxide onto the vehicle components, a transport device for transporting the vehicle components through the cleaning chamber, and a charge discharge device for discharging an electrostatic charge from the vehicle components in order to structurally and/or functionally improve the device.

Abstract: A nonwoven fabric has a volume-giving material, in particular fiber balls, down and/or fine feathers, and has a maximum tensile strength, measured according to DIN EN 29 073 at a mass per unit area of 50 g/m2 in at least one direction, of at least 0.3 N/5 cm, in particular of 0.3 N/5 cm to 100 N/5 cm.

Abstract: A method for producing a volume nonwoven fabric includes the steps of: (a) providing a nonwoven fabric raw material, containing fiber balls and binder fibers; (b) providing an air-laying device, which has at least two spiked rollers between which a gap is formed; (c) processing the nonwoven fabric raw material in the device in an air-laying method, the nonwoven fabric raw material passing through the gap between the spiked rollers, fibers or fiber bundles being pulled from the fiber balls by the spikes; (d) laying on a laying apparatus; and (e) thermally bonding so as to obtain the volume nonwoven fabric.

Abstract: A modular valve system includes a number of functional components such as valves, pressure regulators, adaptors and manifolds for controlling a fluid flow through said valve system, and at least two connecting blocks of different configurations, each associated to one of said functional components. Each one of said connecting blocks constitutes a functional unit together with one functional component mounted on a functional side of said connecting block. All connecting blocks are formed in a rectangular block shape and have an inlet and an outlet on two opposing end sides constituting an inlet side and an outlet side, respectively. The inlet sides of all connecting blocks are of identical configuration. The outlet sides of all connecting blocks are also of identical configuration, wherein outlet and inlet of neighboring, coupled connecting blocks are aligned with each other. Therefore, functional units can be directly coupled for establishing a fluid flow.
