Abstract: A bypass valve having a valve housing and a slide-longitudinally movable in the valve housing. An inlet duct, an outlet duct and a further outlet duct are formed in the valve housing. A closing body (35a) of the slide interacts, by way of its longitudinal movement, with a slide seat formed in the valve housing and thereby opens and closes a first hydraulic connection between the inlet duct and the outlet duct. A further closing body of the slide interacts, by way of its longitudinal movement, with a further slide seat formed in the valve housing and thereby opens and closes a second hydraulic connection between the inlet duct and the further outlet duct. The longitudinal movement of the slide is controlled by way of an electromagnetic actuator. The bypass valve has a cooling device for cooling the actuator.

Abstract: A crosscutter for web materials, particularly paper, has a cutter shaft (13), which comprises a light metal cutter block (19) and a steel shaft end (14). The latter comprises a bearing (12) and drive (17)-receiving spigot and a flange (16), which is connected by means of a positive and nonpositive connection to the cutter block. For nonpositive connection purposes threaded bolts (35) are inserted in bushes (33), which are screwed and bonded into corresponding cutter block recesses. In addition, a reamed bolt connection is provided.
