Zusammenfassung:PURPOSE:To stick granular particles having larger grain sizes to a sheet having a self-adhesive face by accumulating the granular particles into a hopper which is constituted of the above-mentioned sheet and a gate plate provided at an angle intersecting with the diagonal moving direction of the sheet, has a conical section and is opened in the lower part. CONSTITUTION:The sheet 1 having the self-adhesive face 2 on at least the top surface is diagonally moved along the gravity direction. The granular particles 7 are accumulated into the hopper 5 which is constituted by said sheet 1 and the gate plate 3 provided at the angle intersecting with the moving direction of the sheet, has the conical section and is opened 6 in the lower part. The granular particles coming around the self-adhesive face 2 according to the movement thereof among the accumulated granular particles are stuck to the face 2 an the remaining granular particles are dropped through the opening 6. As a result, only the granular particles having the larger grain sizes are stuck to the sheet.
