Seedling-growing tape and method of manufacturing the same
First Claim
1. A seedling-growing sheet comprising:
- a laminate body including an elongated support member and an elongated porous sheet body laminated on the support member;
a number of receptacles for housing seeds and seedlings grown from the seeds, the receptacles being formed in the sheet body of the laminate body and arranged apart from each other in a longitudinal direction of the sheet body; and
a series of cutting perforations for use in cutting out planting pieces each including at least one receptacle from the laminate body, each planting piece being defined between associated adjacent two of the series of cutting perforations, each of the cutting perforations extending in a width direction of the laminate body, the series of cutting perforations being arranged in a longitudinal direction thereof, wherein the series of cutting perforations penetrate both the support member and the sheet body, and the support member includes a plurality of first cutting areas defined by associated two of the series of cutting perforations, the sheet body includes a plurality of second cutting areas each defined by associated adjacent two of the series of cutting perforations, and the first cutting areas and the second cutting areas are put together to constitute the planting pieces.

Abstract
A seedling-growing sheet (1) is in the form of a laminate body (2) consisting of a band-like support member (3) and a porous sheet body (4) laminated on said support member (3). A large number of receptacles (6) for housing rice seeds (15) are formed in the sheet body (4) of the laminate body (2). These receptacles (6) are arranged apart from each other in the longitudinal direction of the support member (3). Formed in the laminate body (2) are cutting perforations (8) consisting of a large number of cut lines (9) along which planting pieces (10) each having at least one receptacle (6) are cut away from the laminate body (2). These cutting perforations (8) are arranged apart from each other in the longitudinal direction of the laminate body (2).

10. A method of manufacturing a seedling-growing sheet comprising:
-
forming a block consisting of a porous material;
slicing said block to form an elongated sheet body;
forming a laminate body by laminating said sheet body on an elongated support member; and
forming a number of receptacles for housing seeds in the sheet body of the laminate body a predetermined distance apart from each other in a longitudinal direction of the laminate body and a series of cutting perforations, each of the series of cutting perforations extending across a width of the laminate body, the series of cutting perforations being arranged a predetermined distance apart from each other in a longitudinal direction of the laminate body in such a way as to define planting pieces each including at least one receptacle, said each planting piece being provided between associated adjacent two of the series of cutting perforations, wherein when stamping is performed on the laminate body, the series of cutting perforations are formed in such a way as to penetrate both the support member and the porous sheet body, so that a plurality of first cutting areas are provided in the support member, a plurality of second cutting areas are provided in the porous sheet body, and the first cutting areas and the second cutting areas are put together to constitute the planting pieces, respectively, each of the first cutting areas and each of the second cutting areas being defined by associated adjacent two of the series of cutting perforations.
