Apparatus for three dimensional surface shaping of synthetic foam |
摘要 |
Synthetic foam compressed between a pattern roller and a smooth compression roller is driven against a cutting edge closely adjacent and tangent to the pattern surface but spaced from the compression roller to reproduce a three dimensional pattern roller surface on the foam sheet. Three dimensional patterns of arbitrary geometries including sharp edged, flat surfaced geometric solids can be reproduced on a foam surface.
