Abstract: A manual work station, in particular a manual work station for manufacturing and/or a manual work station for packaging, comprising a work area accessible to a worker, the manual work station having at least one robotic arm, the manual work station having a safety device, which is designed in such a way that the robotic arm cooperates in a contact-free manner with the worker in the work area. The invention furthermore relates to a control unit for controlling the sequencing of a manual work station.

Abstract: An apparatus and a method are proposed for adjusting a valve lift, particularly a valve needle lift of an injection valve of an internal combustion engine, wherein a valve seat, which is preset in a housing of the valve (20), is axially displaceable in the housing by means of plastic deformation. The apparatus is provided with an adjustment device (50) which generates a feeding motion for a pressing tool (53, 55) in the direction of the plastic deformation and with a measuring device (30) which determines the valve lift that is changeable by way of the plastic deformation of the valve seat and compares the valve lift with a preset desired value, with the adjustment device (50) being controllable by way of the desired value/actual value comparison. The pressing tool (53, 55) is fed by means of a first and, if necessary, by means of at least one further feeding process.
