Abstract

PURPOSE:To obtain the wick useable for long period without change by a method wherein the wick is formed physically integrated non-woven cloth, and its end surface is abutted on and partly overlapped for joining, thereby a heat-proof combustion unit and a fuel suction unit are firmly integrated. CONSTITUTION:In the lower end surface of non-woven cloth 2b of the heat-proof burning unit 2 a concaved groove is provided, in which the upper end surface of the fuel suction unit 3 is inserted, air then by the use of needle punch many fibres of short length for the external layers of surface and back sides in the heat-proof burning unit 2, the random-web layers 2b2 are penetrated each other from the surface through the back, winding a random-web round another in order to secure firmly the joining section abutted on both 2.3 which are integrated and solidified so as to not separate. For the heat-proof combustion unit 2 and the fuel suction unit 3 of the wick body 1, neither sewing threads nor metal joining members or the like are employed, therefore, incomplete combustion, inability of wick movement up and down, damage to the device are eliminated. Also as the joining section is properly abutted, partly overlapped and integrated firmly, sucking fuel is uniformly worked without decrease.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wick for a combustion appliance that uses petroleum (kerosene) as fuel, and relates to a means for connecting a heat-resistant combustion part and a fuel suction part.

[Conventional technology and its problems]

Conventionally, as a technique for connecting the heat-resistant combustion part and the fuel suction part of a wick for a combustion appliance, both parts are sewn together with untwisted thread as shown in Japanese Utility Model Publication No. 39-22383, or
There is a method, as in Japanese Patent No. 12387, in which a nail provided on a band-shaped metal plate is used to pierce the connecting portion of both parts and then bent at the back side.

However, in the case of the former, when the wick is used by attaching it to a device, the repeated up and down operation of the wick may cause the threads in the stitching part to break or loosen, causing the two parts to separate, preventing the suction of fuel from reaching the combustion part. In the latter case, the nails can damage the core cloth, making the core up and down operation unsmooth, and repeated up and down operations can cause the core guide cylinder surface to become damaged by the nails. There were defects such as damage to instruments due to rust.

[Purpose of the invention]

It is an object of the present invention to eliminate the above-mentioned drawbacks, to firmly integrate a heat-resistant combustion part and a fuel suction part, and to efficiently produce a wick that can be used without change over a long period of time.

[Structure of the invention]

In order to achieve the above object, the present invention provides one or more of the heat-resistant combustion section and the fuel suction section with one or more layers of long fibers arranged in one direction and a plurality of short fiber random web layers. The long fiber layer and the short fiber random web layer are laminated alternately so that the short fiber random web layer forms the outermost layer, and are physically integrated by needle punching or stitch bonding so as not to separate. At the same time, the connecting end surfaces of both parts are brought into contact with each other, and a part of the short fiber random web is polymerized, and the short fibers of the short fiber random web in the polymerized part are inserted into the front and back sides with a needle punch to form an integral part. It is characterized by the fact that it connects to
