Drape Assist Frame - In
sheet thermoforming, a frame (made up of anything from
thin wires to thick bars) shaped to the peripheries
of the depressed areas of the mold and suspended above
the sheet to be formed. During forming, the assist frame
drops down, drawing the sheet tightly into the mold
and thereby preventing webbing between high areas of
the mold and permitting closer spacing in multiple molds.
