JP3083148U - Reinforcement tape for winding film for ventilation of agricultural house - Google Patents

Abstract

(57) [Summary] [PROBLEMS] In a hoisting film of an agricultural house, stress is concentrated near a film holding metal fitting at the time of hoisting work, and the film often loses along the film holding metal fitting on the winder side. In addition, if the wind is prolonged by the wind for a long period of time, the end of the rolled-up film repeatedly bends and fatigues, and this portion is often broken. SOLUTION: The both ends of the wound film are reinforced along the winding direction with a reinforcing tape having a width of 20 to 60 mm and a thickness of 0.15 mm or less, which is flexible and has a small load elongation. The reinforcing tape is fastened together with the roll-up film with the film stopper.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to the durability of a rolled film of an agricultural house.

[0002]

[Prior art]

 Conventionally, films such as polyethylene and vinyl chloride have been used as winding films for agricultural houses, but the films are not reinforced.

[Problems to be solved by the invention]

 In the conventional hoisting film 2 for an agricultural house, in the case of the hoisting operation, stress concentrates near the film stopper 5 on the upper part of the winding film 2, and the vicinity of the film stopper 5 on the side of the hoist 4, along the bracket. It often breaks. In addition, there is a defect in durability such that the end of the rolled film repeatedly bends and fatigues when the film is prolonged by the wind for a long time, and this part is often broken.

[0003]

[Means for Solving the Problems]

 Therefore, as a result of various studies to improve the durability of the wound film, it has been found that both ends of the wound film may be reinforced with the reinforcing tape of claim 1.

[0004]

[Embodiment of the invention]

 The contents of the invention will be described more specifically with reference to FIGS. As shown in FIG. 1, a reinforcing tape 3 according to claim 1 is integrated with both ends of a film 2 along a winding direction. As a method of integrating, the adhesive tape 6 is applied so as to cover the reinforcing tape 3 with the adhesive tape 6 (FIG. 2), or an adhesive 7 or an adhesive 7 is applied to one side of the reinforcing tape 3 and the film 2 is wound up. (FIG. 3). The reinforcing portion is in the direction along the winding direction at both ends of the winding film 2, and the upper end of the reinforcing tape 3 is fixed together with the winding film 2 by the film stopper 5. The reinforcing tape 3 must have a width of 20 to 60 mm and a thickness of 0.15 mm or less, have flexibility, and have a lower load elongation than the rolled-up film 2. When the thickness is 0.15 mm or more, when the film is wound together with the film 2, the diameter of the portion where the reinforcing tape 3 is present is too large compared with the diameter of the portion where the reinforcing tape 3 is not present, and the winding workability is poor. As the reinforcing tape 3, a metal tape, a plastic tape, or the like is preferable. There are side ventilation, shoulder ventilation, roof ventilation, and valley ventilation as ventilation methods using a rolled-up film, and reinforcing tape is effective for all of them.

[0005]

[Effect of the invention]

 The installation of the reinforcing tape reduces the breakage of the rolled-up film and greatly improves the durability of the agricultural housing.

Claims (1)

[Utility model registration claims] 1. A wind-up film having a width of 20 to 60 mm and a thickness of 0.15 mm or less for preventing the roll-up film 2 from being broken by being integrated with both ends of the wind-up film 2 for agriculture along the winding direction. Reinforcement tape 3 with flexibility and low load elongation
