Abstract
Masses of particles are structurally supported by the application of vacuum through a support surface having holes thereon that are smaller than the average diameter of the particle mass that is to be supported. The reduced pressure structurally supports particles on the support surface. The mass of particles tends is so well supported that it tends retain its shape unless additional forces are applied. The system comprises the vacuum applicator (e.g., pump), a vacuum carrying system and the support surface. When a mass of particles is supported on the support surface under vacuum, the particles can be carried to a target surface, the mass of particles pressed against the target surface, the mass conforming to the target surface, and the vacuum reduced or stopped, depositing the particle mass onto the surface in excellent shape compliance with that surface.
