Zuu peel off of the workpiece voia mandrel only the clamping head needs to be moved over the bridge so that the Clamping head apindole is supported directly on the bridge. Will now the thorn is back with the help of the Kolbontriobe, so pulled by the blacksmith's box, that's how it results I frictional connection of which is on the clamping head spindle supporting workpiece over the spindle to the bridge, like this that the piston shoots can work with full force, without doti clamping head especially fix to ciüsaon and without to burden other construction materials.
