ABSTRACT:
An apparatus with pivoting blades and closable surfaces for forming a sheet of material into a flower pot or flower pot cover having fins. In an embodiment for forming outwardly extending fins, the apparatus includes a male mold and a plurality of plates arranged in pairs to define a forming opening. The male mold has a plurality of fingers which are laterally extendable from the outer periphery of the male mold. A pneumatic or hydraulic piston and cylinder is provided to move the male mold between a storage position spaced from the forming opening and a forming position within the forming opening. Each pair of plates is movable between an open position and a closed position. In operation, the fingers are extended to push folded portions of a sheet of material between the pairs of plates, which are closed to press the folded portions into fins. In an alternate embodiment for forming outwardly extending fins, pairs of movable plates are positioned between stationary segments. The plates move away from one another to press folded portions of a sheet of material against the adjoining stationary segments to form fins. In another embodiment, a female mold having closable female segments cooperates with blades which are pivotable between the female segments to produce outwardly extending fins. In an apparatus for forming inwardly extending fins, blades are pivoted to push folded portions of a sheet of material between segments of a male mold.
