GUIDE DEVICE FOR TRANSFERRING PLASTIC SHEET ON EXCHANGE OF VINYL SHEET SPREAD ON GREEN HOUSE AND METHOD FOR TRANSFERRING SHEET

摘要

PROBLEM TO BE SOLVED: To solve a problem that it is laborious every year to secure skilled workers for the exchange of a plastic sheet spread on a green house, because the plastic sheet is deteriorated to cause the shortage in lighting and strength, when exposed on winds, rains, and sunshine, and must thereby be exchanged by a new plastic sheet every year in dependence on an area or an environment, and further because works for covering new sheets are simultaneously started on many green houses in dependence on an area. SOLUTION: This guide device for transferring the plastic sheet is used by binding a pulling rope 2 to one end of the plastic sheet 3 repeatedly folded up in the longitudinal direction in a narrow shape, inserting the bound portion into a warhead-like husk member 1, pulling the pulling rope with a winder on the frame 6 of the roof of a green house in a state that the husk member is placed at the head, preventing the plastic sheet from slipping down during the transfer of the plastic sheet, and transferring the bundled plastic sheet at places near to the peak of the green house in approximate parallel to the peak over the whole length of the green house. Thereby, the work for respreading the plastic sheet can easily performed in a short time.
