Abstract: A tube container molding apparatus in which a cylindrical tube is inserted into a split mold in its closed state so that the end section of the tube comes into contact with a cavity face of the split mold. A core is then advanced to fit into the tube from its rear end, and finally a resin melt is introduced into the cavity formed by the cavity face of the split mold and the end face of the core.When the resin melt is injected into the cavity, a tube holding piece pushes the tube against the core to prevent the tube from being drawn out of the cavity.Midway during the advance of the core into the tube, the tube is held by the tube holding piece and the further advance of the tube is made together with the core. Thus, the forward end section of the tube is bent inward to a prescribed width.

An acceleration compensation arithmatic circuit receives outputs of a pair of inclinometer and removes an acceleration component by performing integration twice. This circuit is also designed to remove an integration error. Further, according to the invention, a Doppler radar system and an engine speed/throttle opening system are employed for detection of overload applied to the blade so that one of the detection systems which is most suitable for an actual work can be selected. Furthermore, the device includes both blade height controllers and tilt controllers and performs the two control operations most effectively.
