摘要: A vacuum holddown has a member with an outer surface for temporarily capturing flexible sheet material via force distributed across the through discrete channels. valving mechanism abuts inner of in selectable sliding engagement. The pattern apertures therethrough predetermined such that valve positions produce patterns at member.
