Abstract
In a method of molding a large plastic structure which includes applying a vacuum to draw the molds together, injecting resin into the space between the molds while the vacuum is applied, maintaining the vacuum at least until the resin gels, removing the vacuum, allowing the molded structure to harden, removing the male mold and then removing the molded structure, molding is carried out on a moving production line without danger of disturbing the resin while gelling by disposing the molds on bogies and moving the bogies onto motor driven glide rollers at the point where the resin is injected, and the bogies transported on the glide roller drive until initial gelling has taken place.
Claims6
In an assembly line in which wheeled bogies are transported by a continuous chain drive in an endless path, apparatus for conveying the said bodies over a portion of said path in a manner such as to avoid jars and vibrations comprising;
- a. a glide roller drive system comprising a plurality of spaced rollers adapted to support said bogies such that their wheels are off the ground;
- b. means of restraining said bogies laterally;
- c. ramp means for directing said bogie from its normal track onto said rollers in such a manner that said bogie simultaneously comes into contact with a plurality of said rollers over its length so as to be immediately supported;
- and
- d. means to direct said chain drive to a position below said bogie so as to disengage said chain drive from said bogie and move said chain in a position away from said bogie.
