摘要:
A continuous molding machine (10) for forming two chains (55) of soil plugs (50) for use in germinating seeds or otherwise growing plants. A continuous sheet of paper (22) is corrugated to conform to a series of mold elements (14) and a reaction mixture (32) of polymerizing agent and soil slurry is added over the paper to conform to the mold element shape. Another sheet of paper (38) is added over the top of the mixture (32) and the entire assembly is then passed under a series of pressure belts (42, 44, 46) during which time the mixture (32) is cured. The chain of soil plugs (50) which emerges from the pressure belts (42, 44, 46) is encased on both sides by paper (22, 38) and may be cut to provide a pair of separate soil plug chains (55).

Apparatus for continuously and rapidly forming trays of highly uniform elastomeric soil plugs comprises means for continuously mixing a water-containing soil slurry with a water-reactive pre-polymer compound, means for supplying the soil slurry and the pre-polymer compound to the mixing means at respective controlled rates, and means for delivering the mixed soil slurry and pre-polymer compound to a dispensing station for dispensing into mold receptacles; the receptacles are disposed in a closed path and carried by transport means seriatim past the dispensing station. Releasable bias means biases a tray mold member against a base mold member within each receptacle so as to extrude soil-pre-polymer mixture into plug-molding cavities of the tray mold member. The bias means is released after the plugs within the tray mold member have cured. The operation of the apparatus coordinates the various steps in the plug-molding process with stages of the chemical reaction between the water and pre-polymer compound to form highly uniform plugs at the maximum rate allowable by the chemical reaction.

There is provided a device for cutting large blocks of sod into either strips or small blocks suitable for planting. The device includes first and second spaced cutting mechanisms to sever the large sod blocks along lines parallel and transverse to the path of sod movement through the device. With both of the cutting mechanisms operative, small sod blocks are discharged from the machine. In order to discharge sod strips, means are provided to disable one of the cutting mechanisms.

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.

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. At the first step, the waterproof paste is applied in a given pattern while continuously pulling out two continuous thin films. At the second step, folds are formed in the resulting belt, and the belt is folded in a zigzag fashion. This state is maintained. At the third step, the water-soluble paste is applied to the front side and the rear side of the belt alternately up to each fold. Then, the belt is folded, and pressure is applied to it to stick together the folded belts.
