the spring element 19b and the force created when the clamps 36 37 are bent open elastically the drive shafts 22 are rotated clockwise by 90 degrees when they pass the second stop 31 as a result the cams 23b are pivoted into their open position and the clamps 36 37 are opened by the spring element 19b if the stops 30 31 are in the positions indicated by the dotted line then the passing drive shafts 22 will pivot in exactly the opposite direction this means that the cams 23b are pivoted clockwise from their open position into their second locking position upper gripping pliers shown in fig5 when this occurs the pressure zone 45 presses against the holding notch 43 which forces the clamp 39 s 36 counter arm into the locking position so that a large diameter bottle 2a is gripped and wedged into place the holding notch 43 is also located slightly off center so that the cam 23b can be brought into a locked position adjusting the transport star 41 to accommodate either of the two bottles types is just as straightforward as it is to adjust the transport star 1 shown in fig1 and 2 an adjustment simply involves moving the two slides 33 to the corresponding opposite positions this adjustment can also be made automatically with compressed.
