Latest Patents
One of Wiedenfeld's latest patents is for a blow molding machine. This invention relates to a control means for actuating the valves that supply pressurized blowing fluid and working fluid to the blow mold stations of the blow wheel. The blow wheel features a center-free wheel ring, which is rotatably supported on a base. A stationary rail is positioned facing the inner periphery of the wheel ring, where carriages are adjustably mounted. These carriages accommodate cams that actuate the plungers of the valves mounted on the wheel ring through a yoke, providing a self-holding action. This design facilitates proper valve operation while the blow molding machine continues to operate.
Another significant patent involves a process for producing hollow bodies of oriented thermoplastic material. In this process, a hollow blank with a bottom portion and a cylindrical wall portion is subjected to pre-expansion at the opening. This is followed by a thermofixing treatment. The thermofixing operation may be preceded by a mechanical expansion operation to orient the plastic material forming the wall portion of the blank.
