  • Patent number: 5996513
    Abstract: A strips peeling off apparatus and a carrying conveyor are disposed on a body of a machine for transplanting seedlings. A series of pots is taken out from a multiple series of pots 1 placed on the body through a pair of guide plates by pulling two strips with a pair of taking-out rollers through the pair of guide members toward the front side of the body to expose the seedlings with soil exposed from the pots of the series of pots. The seedlings with soil are carried toward the rear end side at the same velocity as the velocity of the body by clamping the root block portion of the seedling with a first conveyor, and subsequently, with a second conveyor, by clamping the leaf portions of the seedlings to carry the seedlings toward the rear side of the body into a planting groove formed by an opener mounted below the body.

  • Patent number: 5653055
    Abstract: Continuously assembled pots, configured in square or hexagonal cylinders for raising and transplanting seedlings are formed by developing non-adhered portions of a band, which is formed by adhering two sheets of film such as paper or the like. The portion of the band corresponding to a connector portion which connects the pots is folded at a given length, and has an elongated or unfolded length larger than the width of one side of a pot. The folded portion of the band is adhered to itself and to a pot with a water soluble paste, so that the continuously assembled pots are separated by water during raising and pulled out continuously from one end thereof in a line.

  • Patent number: 5595020
    Abstract: An assembly of pots for raising and transplanting seedlings. A plurality of cylindrical pots are made of paper and each pot is connected by a connection member into a continuous form. The connection member includes slits for allowing the spacing between adjacent pots to be elongated to a length corresponding to one intrarow spacing for various kinds of plants. The generally H-shaped or generally U-shaped slits can be vertically and alternatively provided from upper and lower edges of the connection member.

  • Patent number: 5470434
    Abstract: Decay-resistant paper suitable for the manufacture of a pot for raising and transplanting seedling is the one partly containing decayable portions, which is prepared by heating paper made of a natural fiber, or a fiber blend composed of a natural fiber and a synthetic fiber, and impregnated with a compound capable of crosslinking the paper cellulose, at a temperature causing the reaction of antidecay treatment and at a temperature causing no such reaction in different portions. Such decay-resistant paper partly containing decayable portions can be easily prepared by bringing the above-mentioned paper impregnated with a compound capable of crosslinking the paper cellulose into contact in a single step with a heating apparatus comprising a heating part of a temperature causing the reaction of antidecay treatment and a heating part of a temperature causing no such reaction.

  • Patent number: 5415115
    Abstract: A machine for transplanting potted seedlings grown in a series of pots linked together without separating them from one another includes a bottom plate having an upwardly curved leading end portion, and a slot formed in its trailing end portion. A soil opener is fitted in the slot and contains a vertically rotatable pot guide. A pair of soil drawing members are attached to the bottom plate behind the soil opener. A pair of side frames are erected on the bottom plate, and have inwardly directed portions converging toward the soil opener. A pair of pot guides are also provided on the bottom plate inwardly of the side frames.

  • Patent number: 5257475
    Abstract: Herein disclosed is a band for forming a seedling raising bottomed pot aggregate, in which multiple rows of a plurality of pots are aggregated. The bottoms of the pots are formed by making specific planar structures in a material paper having a constant width and by adhering, combining and cutting the paper. The pot aggregate can be easily manufactured by expanding the band. The bottoms are extended from the lower sides of the side walls of the cubes and are folded inward at a right angle from the adjoining extensions. These adjoining extensions are adhered on one of the diagonals of the bottoms, and the extensions on the other diagonal are overlapped.

  • Patent number: 5155935
    Abstract: An assembly of pots for raising and transplantation of seedlings, the assembly made of paper or a paper-like thin film, in which the side wall of each pot is provided, by means of a cut, with tongue-like pieces which can be easily lifted-up toward the outside of the pot by the pressure of seedling roots while in the soil after transplantation, therefore, making the extension of roots from the tongue-like portion both vigorous and untangled with respect to adjacent potted seedlings.

  • Patent number: 5058320
    Abstract: The invention relates to a multiple pot comprising individual pots interconnected by connector portions so as to be capable of being pulled out. The multiple pot is used to raise and transplant seedlings of plants. The invention also relates to a method of fabricating the pot. The pot is designed especially to promote growth of roots across the side walls of the individual pots after transplantation. Also, the resistance encountered when the multiple pot is unfolded is reduced. Further, the individual pots are uniform in size. These feature arise from the facts that the connector portions are formed by applying a waterproof paste discontinuously and that a water-soluble paste is not applied around the edges of the individual pots created when the multiple pot is unfolded. Hence, a coating of the paste is formed in none of these portions. The multiple pot is fabricated by continuously carrying out three steps.

  • Patent number: 4963230
    Abstract: Disclosed herein is agricultural paper to be made into pots for raising seedlings. It is made up of a first layer made chiefly of natural pulp and a second layer made of synthetic fibers having a basis weight of 3-15 g/m.sup.2, said first layer and second layer being joined to each other by the wet papermaking process which intertwines the fibers of the two layers at their joining interface. The second layer is formed by fusion bonding composite synthetic fibers of polymers having different plasticizing temperatures.
