<p>TITLE OF THE INVENTION: METHOD AND APPARATUS FOR FORMING AND TRIMMING THREE-DIMENSIONAL WORK PIECES Three-dimensional work pieces, such as instrument panels or dashboards, are made of initially flat stock or of synthetic material such as a two-component foamably material. The tools of the present apparatus include upper and lower holding tools which are preferably simultaneously shaping tools, and cutting or trimming tools. The upper tools and the cutting or trimming tools may have a common support which is preferably exchangeably secured in a main frame. The shaping tools are moved into a first cooperating position relative to each other, whereby the work piece is formed into the desired shape. The shaping tools may then be locked in the shaping position or they may be moved into a second cooperating position to be rigidly locked in the second position. A tool support such as a table carried by a scissors lift frame is used for moving the shaping tools into the desired positions. The cutting or trimming is then performed by applying pressure to the respective tools. A curing time may be provided between the forming step and the cutting or trimming step.</p> |
