Abstract: A valve plate has a plate portion with a front side elastomeric seal fitted thereon, and a connection apparatus arranged at the rear side for connecting the valve plate to a carrier apparatus of a vacuum valve. The connection apparatus includes first and second elongate connection portions, the first connection portion is located at one side and the second connection portion is located at the other side of the longitudinal center of the plate portion, with each being connected to the plate portion with the two spaced-apart ends thereof. The connection portions are spaced apart from the plate portion in the region between the two ends thereof, with a respective slot formed between the plate portion and the respective connection portion, and have in a central region of the longitudinal extent thereof a connection structure for connection to an end portion of a respective valve rod of the carrier apparatus.

Abstract: A valve plate has a plate portion with an elastomeric seal on a front face and an elongated connecting portion spaced apart from a rear face by a slot for fastening the valve plate to a valve rod. The extension of the connecting portion in the width direction is defined by opposing first and second side edges of the connecting portion when viewed in a plan view of the rear face of the plate portion. A connecting structure is configured in the connecting portion in a central region of the longitudinal extension of the first side edge of the connecting portion for connecting the connecting portion to an end portion of the valve rod. The connecting portion is reinforced in a region of its extension in the width direction adjoining the second side edge, relative to a region of its extension in the width direction adjoining the first side edge.

Abstract: A stamping machine for labels and covers includes a servomotor as a driving element. The servomotor can be directly or indirectly connected to a spindle which causes the stamp to move forward in a linear manner.

Abstract: Some embodiments of the invention relate to a vacuum valve having at least one piston/cylinder arrangement for adjusting a first closure member between a first, a second, and a middle closure member position. In some embodiments, the piston/cylinder arrangement which is coupled mechanically to the first closure member has a cylinder unit and a piston unit. A first seal body and a second seal body can be displaced independently of one another axially relative to the cylinder unit and to the piston unit. A first axial stop of the cylinder unit and a third axial stop of the piston unit are arranged relative to one another such that, in the middle closure member position, the axial movability of the first seal body in the direction of a second pressure chamber is limited jointly by the first axial stop and the third axial stop.

Abstract: A vacuum valve comprises a valve body with a valve opening, a valve plate which is adjustable from an open position, in which it releases the valve opening, to an intermediate position, in which it covers the valve opening but is lifted from the valve seat, into a closed position in which it contacts the valve seat, and from the closed position to the intermediate position into the open position, a valve rod carrying the valve plate, a transverse drive unit by which the valve plate can be displaced in a transverse adjusting direction extending transverse to the longitudinal axis of the valve opening, a longitudinal drive unit by which the valve plate can be displaced in a longitudinal adjusting direction extending parallel to the longitudinal axis of the valve opening and opposite the longitudinal adjusting direction, and a guide device by which the transverse drive unit is guided so as to be displaceable relative to the valve body parallel to the longitudinal adjusting direction.

Abstract: A vacuum valve comprises a valve housing which has an inlet opening and an outlet opening penetrating opposite walls of the valve housing, a valve seat surrounding the inlet opening, and a closure unit which is arranged in an interior space of the valve housing and which has a valve plate which is adjustable between an open position in which it releases the inlet opening, an intermediate position in which it covers the inlet opening but is lifted from the valve seat, and a closed position in which it covers the inlet opening and is pressed against the valve seat, and at least one adjusting piston which is arranged in an interior space of the closure unit and, for the purpose of adjusting the valve plate between its intermediate position and its closed position, is displaceable in direction of its longitudinal center axis between a passive position in which the valve plate is in its intermediate position and an active position in which the valve plate is in its closed position.
