Abstract: It is disclosed a matrix conveyor (10) comprising: a plurality of individual roller modules (28), wherein respectively one roller module (28) is arranged at each point of intersection of a regular grid-shaped structure (68), and wherein the roller modules (28) commonly define a conveying plane (30), which is substantially planar, for transporting a conveying good (72) thereon; and a superordinated control device (12) being adapted to individually control each of the individual roller modules (28) so that the conveying good (72) can be transported along a path (74), which can be planned in advance, wherein a shape of the path (74) is defined by a plurality of overlaps of at least two basic conveying directions (60, 62) of the conveying plane (30); wherein the at least two basic conveying directions (60, 62) geometrically span the conveying plane (30), and wherein each of the roller modules (64) is drivable in only one of the at least two basic conveying directions (60), wherein directly adjacent roller modules

Abstract: A roller closing device is provided with an inner element and with an outer element. These two elements are arranged at least partially in a coaxial manner. The inner element can be deflected radially with respect to the outer element by the use of at least one elastic body which is arranged between the two elements. This elastic body is configured as a rolling diaphragm. A seal is configured between the inner element and the outer element. The seal closes off a gap between the two elements to prevent impurities from entering the roller closing device when any radial deflection of the inner element takes place.

Abstract: A device is used to set a contact pressure between a displaceable roller and another roller or for moving the displaceable roller with respect to the other roller. At least one actuator is subjectible to the action of a pressure medium and presses the displaceable roller toward the other roller with an adjustable force. The pressure of the pressure medium can be adjusted by a valve. A switchover device is provided for use in connecting the valve to different actuators, as desired.

Abstract: The contact pressure between an adjustably mounted first cylinder and a second cylinder in a printing machine, and particularly in a web-fed printing machine can be adjusted. An actuator is usable to force the first cylinder toward the second cylinder with an adjustable force. A fixing device is usable to fix the first cylinder in a desired position relative to the second cylinder.

Abstract: A pressure force exerted by first and second cylinders upon at least a third cylinder in a printing machine is regulated by a pressure regulating device. The device can also be using for moving a first cylinder and at least one second cylinder into and out of contact with a third cylinder. Actuators, which exert a radial force on a cylinder cooperating with the actuators, are provided. An aperture angle between the radial forces exerted by two actuators on the same cylinder is the same in both cylinders. That aperture angle is independent of an aperture angle formed by the pressure force exerted by the first and second cylinders on the third cylinder.

Abstract: The forces exerted by actuators are detected and devices are provided, which use those detected forces to regulate a pressure force exerted by one cylinder against another cylinder in a printing machine. The several forces can also be used for placing or removing one cylinder with respect to another cylinder. One cylinder may be mounted in a cylinder holder which is, in turn, mounted in a frame holder. At least two actuators are arranged between the cylinder holder and the frame holder. These actuators exert a radially directed force against the cylinder holder when they are actuated by a control signal.
