Description

platte 42 geglättet, wenn der Formkasten 15 unter diesen Einrichtungen hindurchbewegt wird. Sobald der Formkasten 15 seine Ausgangsstellung erreicht hat, können die Kernrohre 13 herausgezogen und die Entformung vorgenommen werden.Plate 42 smoothed when the molding box 15 is moved under these devices. As soon the molding box 15 has reached its starting position, the core tubes 13 can be pulled out and the Demolding can be made.

Zu einer etwas abgewandelten Arbeitsweise gelangt man, wenn man das Füllen des Formkastens 15 und das Verdichten der eingefüllten Masse in der gleichen Stellung vornimmt, also die Vibrationsplatte 17 nach dem Einfüllen der Betonmasse über den Formkasten 15 bewegt und dann absenkt. Nach dem Anheben der Vibrationsplatte 17 kann dann der Formkasten 15 unter dem Füll- und Vorratstrichter 40 hindurch bewegt und die Deckschicht aufgebracht werden. In diesem Falle müßten natürlich der Verteiler 41 und die Glättungsplatte 42 auf der entgegengesetzten Seite des Füll- und Vorratstrichters 40 angeordnet sein. Nach dem Aufbringen der Deckschicht und dem Ausziehen der Kernrohre 13 kann dann die Entformung und der Abtransport des ίο Frischlings mit der Unterlagsplatte 16 vorgenommen werden.One arrives at a somewhat modified mode of operation if one starts filling the molding box 15 and performs the compression of the filled mass in the same position, i.e. the vibrating plate 17 after filling the concrete mass moved over the molding box 15 and then lowered. After lifting the vibration plate 17 can then the molding box 15 under the filling and storage hopper 40 moved through and the top layer applied. In this case, of course, the distributor would have to 41 and the smoothing plate 42 are arranged on the opposite side of the filling and storage hopper 40 be. After applying the cover layer and pulling out the core tubes 13 can then the demoulding and the removal of the ίο fresh product with the support plate 16 is carried out will.
