adopted fig4 however shows a running rail 32 which guides the rolling block 8 with its downwardly projecting wheel the running rail 32 can also be referred to as a travel rail fig4 also shows a part of a finished pylon segment 34 and a mold bottom 36 with which two outer shuttering elements 2 and an inner shuttering element together form a concrete mold for production of the illustrated pylon segment fig4 shows an opened position in which the outer shuttering element 2 has already been pulled away from the pylon segment 34 to clear it fig4 also shows on the outer shuttering element 2 a separating means 38 which can also be referred to as a separating element in the closed condition when concrete can be poured into such a mold or can harden therein the outer shuttering element 2 as shown in fig4 is connected to a further outer shuttering element 2 at its contact edge 4 as can be seen in fig2 the separating means 38 is provided to implement or facilitate separation of two outer shuttering elements 2 connected in that way the separating means 38 has a fastening and guide portion 40 with which the separating element is fixedly connected to the outer shuttering element 2 a pressure screw 42 is provided on the fastening and guide portion 40 as a further component of the separating means 38 in relation to that screw 42 the other outer shuttering element which is not shown in fig4 in the region of its contact edge has a pressure region against which the screw 42 is to be screwed when the screw 42 is screwed against that pressure region u2014 which corresponds to screwing towards the left in fig4 u2014.
