Abstract: An instrument for a robotic surgery system that includes a housing and an outer shaft joined to an effector at a distal end, and to the housing at a proximal end. The connection is rotatory so that the outer shaft can rotate about its longitudinal axis. The rotatory connection takes place by way of a first coupling element that is fixed to the outer shaft. The instrument also includes a first inner shaft arranged within the outer shaft and movably supported relative to it. The relative motion may be either a rotation or translation. The first inner shaft is joined with the effector at a distal end and fixed to a second coupling element at a proximal end. The first coupling element encloses the first inner shaft in a first transition region at the proximal end of the outer shaft, and a first sealing element encloses the first inner shaft.

Abstract: A device for producing textile planar structures formed of a plurality of portions deposited beside one another of fiber rovings. A supply device provides a fiber rovings at a transfer installation. A plurality of path guiding rails are disposed beside one another and above the depositing face. A gripper unit and a cutting unit are disposed on each path guiding rail. Each gripper unit and each cutting unit is movable and positionable along the path guiding rail independently of the gripper units and cutting units of the other path guiding rails. The gripper units grab the fiber roving from the transfer installation and move their free end to a desired terminal position. The cutting units severs the rovings at a cutting position. The gripper units and the cutting units have a downholder for pressing the fiber roving against the depositing face.

Abstract: A cutting unit includes a blade for cutting at least one fiber, particularly on a cutting support, and particularly for producing fiber preforms which are, in particular, a precursor in the production of fiber-reinforced plastic components. A guide device is arranged so as to guide at least one of either the blade or a cutting support which can be moved relative to the blade, along a linear path in order for cutting to take place. At least one such cutting unit is preferably used in a device for producing fiber preforms which are, in particular, a precursor in the production of fiber-reinforced plastic components. The device has at least one unwinding station for providing at least one fiber, and at least one gripper which can grip individual or a plurality of fibers at their front ends.

Abstract: In a device for positioning a tool in a working area wherein two spaced parallel horizontal guide tracks are provided and a guide slide is movably supported by each guide track, a coupler link is supported on each guide slide so as to be pivotable about a vertical pivot joint axis and the coupler links are joined to each other pivotably about another joint having an axis parallel to the vertical pivot joints of the coupler links, and a spindle extends from the other joint of the coupler links in alignment with the axis thereof so as to be linearly adjustable and is provided with a tool. The spindle with the tool is position-adjustable by linear movement of the guide slides along the tracks whereby the tool supported by the coupler links which are longer than the distance between the two guide tracks can cover also areas at opposite sides of the two parallel guide tracks.

Abstract: A device for positioning a tool within a predetermined working area includes two guides which are parallel to one another and run in a first coordinate direction, and on which in each case a guide slide is mounted in a longitudinally adjustable manner. The guide slides are connected by a supporting structure which carries the tool and which also permits a movement of the tool in a second coordinate direction. It is connected to the guide slides so as to be movable about in each case a first or second joint axis, respectively, parallel to a third coordinate direction. It includes two coupler links which are connected to one another by a third joint axis parallel to the first and second joint axes. Coaxially to this third joint axis, the supporting structure is provided with a spindle which carries the tool and is adjustable linearly in the direction of the third coordinate direction and independently thereof by a rotation angle about the third joint axis.
