Abstract: A sizing device adapted for automatic blow mandril adjustment for plastic blow molding machines is provided with at least blow mandril having a blow nozzle and a cutting edge and forming a module with a blow mandrel carrier. The blow mandril is guided in a guide plane extending perpendicularly to the axis of the blow mandril for adjustment in relation to a module carrier suitable for connection with the blow molding machine in the axial and any desired radial direction and in both directions is respectively able to be locked by means of a respective setting means on the blow mandril carrier adapted to be connected with the module carrier. The blow mandril is urged in relation to the module carrier axially toward the blow nozzle into the home position and is able to be moved in the opposite direction overriding the biasing action as far as engagement with the blow mandrel carrier. The setting means for locking the at least one blow mandril in position are able to be operated by means of pressure medium.

Abstract: On the sizing unit of a blow molding machine, one or more blow mandrels are mounted in blow mandrel holders and are centered in sizing plate openings. To obtain faster and more accurate centering, the blow mandrel holder has independently adjustable sleeve and flange parts. The sleeve adjusts axial location while the flange fixes radial location. Conical mandrel tips and sizing plate openings facilitate rapid alignment as the blow mandrels are lowered.

Abstract: A cleaning device for guns in which a cleaning brush fastened to a brush carrier is moved to-and-fro in the barrel by means of a rod. A drive unit with drive wheels which can be engaged with the rod is arranged in the front of the muzzle of the gun so that the cleaning operation can be simply carried out with a small expenditure of time and labor.

Abstract: A loading device with a rammer, arranged for coupling with ammunition bases, exhibiting a transport and coupling segment. The coupling segment exhibits a plurality of grippers with claws adapted to engage an undercut base of ammunition. The bearing member for the grippers is movable with respect to the transport segment with a first limit position, corresponding to the maximum distance of the bearing member from the transport segment. The bearing member has a stop element for fixing the position of the bearing member relative to the ammunition base. After the rammer is moved against the base the transport segment is moved toward the coupling segment. The grippers are moved out of their rest positions assumed by the action of a resetting mechanism, and into their gripping positions against the edge of the base of the ammunition by an actuating member.
