Abstract: In a process for depositing large dry textile fiber webs on a component shape, a rolled up textile fiber web is deposited fully automatically, by means of robots. A robot-carrier cloth gripper grips the end of the textile fiber web to be deposited, and places it on the component shape. The web is then unwound from the roll by a robot-carried cloth unwinding stand, and is deposited on the component shape. During the depositing, the textile fiber web is draped by means of robot-carried heated sliding metal sheets or robot-carried movably disposed heated rollers. The depositing operation is continuously monitored and automatically readjusted to maintain a constant depositing rate. Alignment of the textile fiber web relative to the component shape is also monitored continuously by optical devices, and is readjusted as required.

Abstract: Apparatus and method for handling workpieces using a suction gripper having a suction plate including a plurality of suction openings connected to a vacuum source. The apparatus includes at least one vacuum source, a suction plate having a plurality of openings, at least one movable template, which defines an active area, positionable on the suction plate, and at least one pair of fans arranged to be contrarotating.

Abstract: In a method for welding joint partners, a shaped piece that is extruded out of a welding filler material is arranged between joint partners, which are to be connected, in such a way that it is in contact with both joint partners. The section of the shaped piece is matched to the geometry of at least one of the joint partners, so that before welding, the shaped piece is connected to the at least one joint partner in a form-locking manner. Subsequently, the joint partners are welded together along the shaped piece.

Abstract: A method and a device for the precision turning of a workpiece made of a heat-treatable steel permits a dry hard precision turning of hardened workpiece surfaces without tempering. In order also to allow precision turning and hardening of unhardened workpiece surfaces which are simultaneous in terms of production time, use is made of the local temporary heating of the workpiece caused by machining. The workpiece surface is heated further locally by the action of a laser beam, in the region directly behind the cutter, up to the transformation temperature of the material to be machined via an optical fiber integrated in the tool. The surface is then self-quenched and, as a result, hardened close to the surface. At the same time, the surface temperature at the point of action of the laser beam can be recorded thermographically and, this actual temperature signal can be used to adjust the power of the laser beam so as to maintain the desired temperature.
