Abstract:
1. A method for arranging a plurality of granular particles in each of a plurality of arrangement areas which are partitioned from one another in a predetermined pattern, the method comprising the steps of: carrying an air-permeable carrier web along a predetermined carrying path while holding a first surface of the carrier web on a carrying surface of a carrier device; dispensing the granular particles onto a second surface, opposite to the first surface, of the carrier web being carried; drawing a first air from a plurality of suction holes repeatedly alternating, in a first direction, with discharge holes formed in the carrying surface along the first direction and from a plurality of suction holes repeatedly alternating, in a second direction intersecting with the first direction, with discharge holes formed in the carrying surface along the second direction through the carrier web, thereby holding some of the plurality of granular particles on each suction area on the second surface of the carrier web corresponding to one of the suction holes; and while drawing the first air, discharging a second air from the discharge holes open in non-suction areas that repeatedly alternate with the suction holes in the first direction and the second direction toward the second surface of the carrier web, whereby some other ones of the plurality of granular particles on the non-suction areas blown away by the second air having passed through the carrier web via the second surface toward at least one of the suction areas, thus arranging the granular particles in each of the arrangement areas in the predetermined pattern on the carrier web.
