Description

Sheet coating apparatus for seed tape {SHEET COATING APPARATUS FOR SEED TAPE}

This invention relates to the sheet | seat coating apparatus for seed tapes for mainly covering the seed tapes which were laid on the soil soil with sheet members made of synthetic resins, such as a polyethylene sheet or a vinyl sheet, for example.

The present applicant has already proposed a sheet coating apparatus (Patent No. 54-70842) in a seed tape laying machine. This apparatus was used after having previously punched a hole by a punching device at predetermined intervals coincident with the seed attachment position so as to expose only the seed attachment portions provided at predetermined intervals of the seed tape from the sheet members. In addition, instead of forming the hole, for example, a cutting device is used to form an approximately cut shape in the sheet member surface, and then only the seed attachment portion of the seed tape is exposed to the hole formed by the cutting part. In some cases, it was laid on the ground.

However, in the case of using such a conventional hole in advance, since the strength against the tensile force applied around the hole of the sheet member becomes very weak, the sheet member is pulled out of the sheet reel and placed on the soil by the suppressor roller. In the meantime, the periphery of the hole of the sheet member is broken. In addition, when the cut piece is formed on the sheet member surface and is laid on the soil with only the seed attachment portion of the seed tape exposed by the cut portion, the cut pieces flutter in the wind. There was a problem that can result in enormous harm to germination.

Accordingly, the present invention has been made in view of the above-described conventional circumstances, and the hole is not formed in the state pulled out of the sheet reel, so that the hole is formed just before the sheet member is laid on the soil by the suppression roller. By doing so, damage around the hole of the sheet member can be prevented in advance, and damage to growing the seed is caused, such as blocking the hole formed by the roughly cut portion of the sheet member by flapping of the cut piece. It is possible to provide a sheet covering apparatus and a sheet covering method, which can cover the soil in which the seed tape is placed, can be simply covered by leaving the seed portion securely, and furthermore, by using a sheet member of a type that does not remain in the soil. It aims to do it.
