Реферат: Process and device for the manufacture of containers of plastic material and plastic objects in the blowing process, in which a tubular raw body is filled in a divided mold, the tubular body is separated and with the aid of a device the blower expands to the final shape, characterized in that the crushing and welding of the hose is effected by a multi-part bottom mold, movable in the transverse direction with respect to the raw body, in which approximately perpendicular to the plane for the separation of the mold there are protrusions, which produce depressions in the marginal runner of the bottom of the finished part and only after the closing of the mold of the bottom a meeting of the mold of the shell of the container, respectively of the mold of the hollow body, the hose, above the mold is separated with a separating knife or similar, then the bottom part of the mold was lev and the blow mandrel or the like is inserted for the subsequent blowing process.
