Abstract: A system for manufacturing a dry electrode for an energy storage device are disclosed. The system includes a first dry electrode material delivery system configured to deliver a dry electrode material, a first calendering roll, a second calendering roll, and a controller. The second calendering roll is configured to form a first nip between the first calendering roll and the second calendering roll. The first nip is configured to receive the dry electrode material from the first dry electrode material delivery system, and form a dry electrode film from the dry electrode material. The controller is configured to control a rotational velocity of the second calendering roll to be greater than a rotational velocity of the first calendering roll.

Abstract: The invention relates to an assembly for contactlessly measuring the thickness of a continuous material web, in particular a flexible, elastic, and/or coated material web, having: a material web which is guided on the surface of a contact body, in particular a contact body which is cylindrical at least in some sections; and a sensor assembly for measuring the thickness of the material web, wherein at least one first sensor is oriented toward an upper face of the material web and at least one second sensor, lying opposite the first sensor, is oriented toward a lower face of the material web. The invention is characterized in that the second sensor is at least partially arranged below the contact region between the material web and the contact body.

Abstract: A device for producing a releasable clearance-free position of a rolling bearing, having a rolling bearing which has an outer ring, an inner ring mounted on a shaft and a plurality of rolling elements arranged between the inner ring and the outer ring, and having a tensioning device mounted on the circumference of the rolling bearing outer ring for generating a radial preload which is uniform over the outer circumference of the rolling bearing outer ring between the tensioning device and the rolling bearing outer ring, wherein the tensioning device has an axially adjustable tensioning element which can be brought into a first alignment in which the rolling bearing has play, and which can be brought into a second alignment in which the rolling bearing is free of play. A corresponding method is also described.

Abstract: A roller arrangement includes at least three parallel-axis rollers with a respective nip formed between adjacent rollers. Each of the rollers having a journal at both axial ends and is pivot-mounted via the respective roller journals. At least two bearings being arranged axially adjacent to one another at least on both of a first roller journal of a first, second and third adjacent rollers. A compressive stress is generated between an inner bearing on the first roller journal of the first roller and an outer bearing on the first roller journal of the second roller and a tensile stress is generated between an outer bearing on the first roller journal of the first roller and an inner bearing on the first roller journal of the second roller or vice versa. Similarly, compressive and tensile stresses are generated between the bearings on respective journals of the second and third adjacent rollers.
