    • A supporting bed (20) for supporting a stack of sheet material (36) in a cutting machine (10) of the type retaining the material by means of a vacuum (40) applied from below the supporting bed is manufactured from a sheet of reticulated polyurethane foam material which has been compressed under heat and pressure so as to be permanently reduced to approximately 10-35% of its initial thickness. The degree of compression, the temperature and compression time, and the porosity of the reticulated polyurethane foam starting material are selected to provide particular airflow and firmness characteristics for the finished supporting bed. In a preferred embodiment of the invention, the starting material is a reticulated grafted polyether foam having a porosity of 30 pores per inch and a sheet thickness of 5 inches. The sheet of material is compressed to a thickness of one inch and retained under pressure for 10 minutes at a temperature of about 400 DEG F. In accordance with another embodiment, the supporting bed is manufactured from a composite structure of starting material including individual layers of reticulated foam material separate by layers of a hot melt adhesive web.
    • 用于在由支撑床下方施加的真空(40)保持材料的类型的切割机(10)中支撑一叠片材(36)的支撑床(20)由一块网状 聚氨酯泡沫材料已经在热和压力下被压缩,以便永久地减小到其初始厚度的约10-35%。 选择网状聚氨酯泡沫起始材料的压缩度,温度和压缩时间以及孔隙率,以为成品支撑床提供特定的气流和坚固性。 在本发明的优选实施方案中,起始材料是具有30英寸孔隙率和5英寸厚度的网状接枝聚醚泡沫体。 将该片材压缩至1英寸的厚度,并在约400°F的温度下保持压力10分钟。根据另一个实施方案,支撑床由起始材料的复合结构制成,包括单独的层 网状泡沫材料由热熔粘合剂纤维网分层。
