Dieboard and method of construction |
摘要 |
A dieboard for diecutting machinery includes a face layer and a backing layer constructed of a resin-impregnated pulp paper sheet material, and a plurality of core layers constructed of a natural wood veneer located between the face and backing layers. The veneer layers adjacent the face and backing layers have a grain direction that is substantially parallel to a longitudinal axis of the dieboard. The layers are then shaped and laminated together to from the dieboard. The resulting dieboard is relatively free of surface defects.
