At least one double-acting hydraulic advance cylinder 30 is supported between cradle 22 and movable plate 14 with the body of the cylinder attached to the cradle, while the piston 33 of the cylinder is connected to the movable plate via a rod 34. Two ZuftlhniTigsTrenals for one hydraulic pressure medium, 36 and 37, open into the body 32 bu both sides of the piston 33, the supply of the pressure medium via the channel 36 causing the plate 14 to move in the direction the fixed plate 11 causes. In contrast, a supply of medium in the channel 37 causes a relative distance between the two plates from each other. In the following, the description is given on the basis of a single approach cylinder, but of course the locking device can have more than one, have such a cylinder.

Between the cradle 22 and the movable plate 14 is a Srägerflansch 40 interposed, the slidable on the TÜhrungsstangen 15 is mounted. In the middle part, the plan carries on its surface turned towards the cradle 22 an arrangement of rods 42 that form the body 43 of a control cylinder 44 wear, which is parallel to the rods 15; stretches and a central opening 46 of the cradle 22 passes through.

Due to these arrangements, when the pressure medium is poured into the cylinder through the opening 3 , the stop lever 75 is pushed back against the piston 52 until it comes into contact with the absate 80, thereby limiting its displacement

Apart from that, it does not matter whether the medium flows in through the channel 82 or not, because the cross section of the piston 78 is the larger and the resulting force against the piston

The head 61 is slid against the movable platen and the Knee joint mechanism shifted into its blooming position comes to a standstill in an intermediate or rest position, as defined above (Figure 2). This position can be modified by modifying the length of the rods 53 and 57 by actuating the nut 56.

The pressure in the approach piston 30 is then reversed. The movable one Plate shifts old according to the arrangement of the snie lever mechanism and the molded part 15 comes into contact with the molded part 12. During this movement, the mirror shaft 87 of the guide rod 86 'comes under the compensation wedge 88. The latter is pushed through Lowered supply of pressure medium into the cylinder 90 via the channel 91; this lowering takes place until there is no play between the flat 87 and 94 »ore is available. Any variation in the The thickness of the mold is thus compensated for by a more or more pronounced pitching of the trowel. .

BU plate 14 cannot move backwards.

The pressure at 85 is now released. The arbelte flask that is still under pressure, pushes the signal piston, 75 back; the head 61 slides against the movable platen by operating the toggle joints and that up to the cutter comes into contact with the flange 40, which is a mutually cursed
