The present invention relates to an apparatus for continuous vacuum forming of a thermoplastic material between a pair of rotating flexible belts in which one belt includes a plurality of teeth, which are received in a plurality of indentations of the other belt. Each of the belts includes a mold, which forms a channel when the belts are adjacent to one another. A vacuum is applied to at least one of the flexible belts for drawing material received in the channel and alignment of the belts. Preferably, a vacuum can be applied to both of the belts for improved alignment. Each belt can include a plurality of apertures, which are in fluid flow communication with a plurality of perforations of a flat support belt positioned over a vacuum manifold.
