Problems solved by technology

By the way, if the material and thickness are taken into consideration to improve flexibility, the shape retention of the catheter will decrease, and it is difficult to satisfy both flexibility and shape retention with a wall of a flat shape as described above.
In addition, it is considered to make the wall into a bellows structure in order to improve flexibility. Since the inner surface of the duct cannot be flattened by the bellows structure, there will be a problem of high air resistance, and there is

Embodiment Construction

[0070] Fig. 1 and Fig. 2 show hoses for air conditioners (the hoses used in air conditioners are generally referred to as ducts). In addition to being used in air conditioners, this hose can also be used as a duct (connecting hose) for guiding air for various blowers and supply and exhaust fans. In addition, if it is used to guide liquid, granular or powder, etc., Either one will do. The hose of the present invention can be used particularly effectively where light weight and shape retention are required, and where flexibility is required.

[0071] As shown in Figures 1 and 2, the above-mentioned hose is manufactured using the hose forming device shown in Figure 3, which includes: an automatic guide as a driving rotary body driven to rotate in the direction of arrow A in the figure Equipment 1 ; and two extruders 4 , 5 for extruding the reinforcement material 2 and the strip 3 forming the body of the hose onto this automatic guiding equipment 1 . Therefore, by using the extr...

Abstract

A hose having both excellent flexibility and shape retainability and advantageous in construction efficiency and cost efficiency. The hose comprises hard synthetic resin reinforcement material (2) spirally fed and having, on both sides of the top part (2D) thereof in the tube axial direction, receiving surfaces (2a) and (2b) positioned on the radial inner side toward the end part thereof and a soft synthetic resin hose body for covering the spirally fed reinforcement materials (2). The reinforcement materials (2) are spirally fed in the state of the top parts being positioned on the radial outer side thereof, a soft synthetic resin tape material (3) is fed to the fed reinforcement (2), and while covering parts (3A) projected in a generally arc shape to the center of the reinforcement materials (2) by melting the tape material or with an adhesive agent.

Description

technical field [0001] The present invention relates to hoses used as flexible air-conditioning hoses, hoses for connecting various blowers and air supply and exhaust fans, hoses for guiding granules and powders, hoses for guiding liquids, etc. Hoses for guiding gases and liquids or granules and powders. In addition, hoses that guide gas, such as air-conditioning hoses and connection hoses, are generally called ducts. Background technique [0002] A catheter as an example of the above-mentioned hose is described. It is preferable that the catheter not only has light weight and shape retention, but also has flexibility. As a conventional catheter, it has been proposed to combine a synthetic resin coating material with a helical core. materials to form a spiral hose (for example, refer to Patent Document 1). [0003] Patent Document 1: JP-A-8-296888 (see FIG. 1 ) [0004] In the above-mentioned Patent Document 1, since the synthetic resin coating material is formed with fla...
