  • Continuous assemblage of pots for raising and transplanting seedlings and method of manufacturing the same
    Patent number: 8099901
    Abstract: A continuous assemblage of pots for raising and transplanting seedlings and a method of manufacturing the assemblage is provided, in which it is possible to extend the length of a link piece without folding an extension portion or arranging a slit, thereby making it possible to handle enlargement of the interval between the planted seedlings stably and reliably. A link piece is formed by folding back both ends of a strip-shaped thin film in the length direction, such that approximately one-fourth of the length of the thin film is folded back onto the same face of the thin film at each end, then attaching the folded-back portions to the same face of the thin film with a water-soluble adhesive. The link pieces are disposed in two rows in a staggered arrangement in which the folded-back portions are oriented such that they face the folded-back portions of the opposing link pieces.
