Abstract

Abstract An apparatus for making paper cylinders for nursing seedlings in which pasted, cut pieces are transferred, piled and stuck together by pressing, the apparatus includes transfer members positioned to receive cut pieces, the transfer members including a rotary cylinder having a surface provided with a plurality of grooves and a plurality of air passageways which open to said surface and extend from air holes in the cylinder pieces. A lamination table is positioned in the vicinity of the rotary cylinder. A pressing mechanism is positioned in the vicinity of the lamination table, the pressing mechanism including a pressing member fixed to a bell crank shaft in correspondence to the grooves so as to be reciprocated between the grooves and the table by motion of the bell crank shaft, edge aligning means are mounted on ends of the bell crank shaft for aligning both side portions of the cut pieces by rocking motion thereof. The pressing mechanism and the edge aligning means are connected integrally through a bell crank mechanism and are arranged opposite the lamination table.
