Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing an oil combustion wick for use in oil burning equipment such as an oil stove.

Generally, an oil combustion wick uses a heat-resistant material such as glass fiber for the combustion part on the upper end, and cotton fiber, etc., which has a great oil absorption effect, on the lower end.
The heat-resistant core cloth made of a heat-resistant material and the oil-absorbent core cloth made of a good oil-absorbent material are connected to each other.

In such oil-burning wicks, oil is sucked up by the highly oil-absorbing core fabric and sent to the heat-resistant core fabric.
Since the combustion is carried out at the upper end, it is necessary for the oil to transfer from the good oil-absorbing core fabric to the heat-resistant core fabric without delay, and to extinguish the oil by sliding the entire body down and Since this is carried out by drawing the core fabric into the cylinder, it is necessary that the connection between the two core fabric parts described above be strong.

In response to these demands, conventional methods for connecting both core fabrics include a method in which a heat-resistant core fabric and a highly oil-absorbing core fabric are butted against each other and sewn together using a sewing machine; There is a method (Japanese Patent Publication No. 58-7885) in which the fiber bundles constituting the cloth section are knitted by making the folded portions enter into the other side.

However, in the former conventional method, both core fabric parts are knitted separately and then cut to the required length.
Furthermore, because the cut surfaces are butted together and sewn together, multiple steps are required to complete the finished product, and there is no risk of misalignment or tautness at the joints, resulting in a rough, hard feeling. It was something I couldn't get.

On the other hand, in the latter method, the same knitting machine with a single row of needles is used to knit both core fabric sections simultaneously, which simplifies the manufacturing process. It is impossible to prevent the thickening of the bulge in the joined part, that is, the convoluted part, and the uniformity of the entire core is significantly lacking.Furthermore, the fiber bundles are convoluted at the part where both fiber bundles are folded back, and this is knitted with loop yarn. As a result, the loop yarn is subjected to a stronger load than other parts, and the fiber bundle is tied up, resulting in a hanging state, so the oil delivery by capillary action is inferior to the above-mentioned arrangement in which the cut surfaces are butted, Sufficient oil could not be sucked up, and the lack of oil supply resulted in insufficient combustion, resulting in a low combustion capacity.

In view of the above-mentioned problems, the present invention allows the heat-resistant core fabric portion and the highly oil-absorbing core fabric portion to be knitted simultaneously using the same knitting machine, thereby simplifying the manufacturing process and increasing manufacturing efficiency. Moreover, the purpose of the present invention is to provide a method for manufacturing an oil combustion wick that has a joining structure similar to the conventional joining by butting cut surfaces and enables uniform and stable large-volume oil delivery at the joining part. This configuration uses a knitting machine with two rows of needles, front and back.In one needle row, a heat-resistant fiber bundle is inserted horizontally to form a heat-resistant core fabric, and in the other needle row, a heat-resistant core fabric is inserted. A good oil-absorbing core fabric is knitted in parallel by inserting the fiber bundles horizontally, and at the same time, both core fabrics are knitted in a connected state in a part of both needle rows, and then both core fabrics are overlapped. The production of an oil combustion wick is characterized by cutting along the connecting warp knitted in the connected state, and then opening both core fabric parts to each other and abutting the cut surfaces against each other while connected by the connecting warp. resides in the law.

Next, an example of implementation of the present invention will be described with reference to the drawings.

Although not shown in the figure, this method has two rows of needles arranged in front and back, and fiber bundles are separately inserted as weft threads in both needle rows, making it possible to knit two pieces of cloth simultaneously and in parallel. A so-called double latsiel knitting machine is used. With such a conventional knitting machine, as shown in FIG. 1, a good oil-absorbing fiber bundle 10 is used as a weft yarn by a back row of needles, and a large number of warp yarns 11, 11, etc. are knitted at regular intervals, and a good quality yarn is knitted. The oil-absorbing core fabric portion 12 is formed one after another. On the other hand, by using the front needle row, heat-resistant fiber bundles 13 made of glass fibers are used as weft threads, and similarly to the back knitting, a large number of warp threads 14, 14, etc. are spaced apart at regular intervals, and the heat-resistant core fabric portion 15 is knitted as described above. It is molded in parallel with and simultaneously with the good oil-absorbing core cloth part 12.

The lengths of both core fabric parts 12 and 15 are formed to be twice the length of each of the oil-absorbing core fabric part and the heat-resistant core fabric part in the desired oil-burning core fabric part. A heat-resistant core fabric section 1 is placed in the center of the oil-absorbent core fabric section 12.
Organize in an arrangement where 5 is located.

In addition, when knitting both core fabric parts 12 and 15 at the same time,
In its central part two rows of connecting warp threads 16a, 1
Only the core fabric parts 6b are knitted in a connected state so as to straddle between both the core fabric parts 12 and 15. Alternatively, the threads may be connected using only one of the threads 16a or 16b by stitching or the like. In this connection, both core fabric portions 12 and 15 are separated for a required period of time and then connected.

In this way, both the core fabric parts 12 and 15 are simultaneously knitted until they reach a certain length, and then cut at the center between the connecting warp yarns 16a and 16b while they are overlapped with each other. The distance between the connecting warps 16a and 16b is set to be the same as or slightly longer than the distance when the core fabric portions 12 and 15 are knitted.

After cutting the core fabric portions 12 and 15 in this way, they are opened from each other around the cut surfaces as shown in FIG. 4, and the cut surfaces are butted against each other. At this time, the connecting warp 16a or 16b knits the fiber bundles 10, 13 at a position close to the cut surface, and connects both the core fabric parts 12, 15 along one side of the butt part of the core fabric parts 12, 15. state.

In this way, both the core fabric parts 12 and 15 are aligned in a line in a butted state, and the auxiliary tape 17 is adhered to the surface opposite to the connecting warp threads 16a or 16b at the abutting part, so that the space between both the core fabric parts 12 and 15 is Strengthen connections. Note that without using the auxiliary tape 17, the two butted core fabric portions may be sewn together in the same manner as in the prior art.

In addition, in the above-mentioned embodiment, both core fabric parts are knitted to double the length, and this is divided into two parts and molded, but as shown in FIG. Knit it to the length of one sheet, and connect the ends with 16 warp threads.
The ends may be cut after knitting, and as shown in FIG. 15 and may be cut in the same manner as described above.

The method for manufacturing the oil-burning wick of the present invention is constructed as described above, and uses a knitting machine having two rows of needles to overlay and parallel the heat-resistant core fabric portion and the oil-absorbing core fabric portion with each other. knitting at the same time, some of the warp threads are knitted in a connected arrangement between the front and rear core fabric parts, and both core fabric parts are cut along the connecting warp threads with both core fabric parts overlapped,
By opening both core fabric parts around the cut surface and arranging the cut surfaces against each other to integrate both core fabric parts into a continuous arrangement, it is possible to use the same knitting machine with a good oil-absorbing core. The fabric portion and the heat-resistant core fabric portion can be knitted at the same time, and both core fabric portions are connected at the same time as knitting, so the manufacturing process is significantly simplified compared to the conventional butt-arranged core, and furthermore, at the butt portion, There is no misalignment between the two core fabric parts, and since the two core fabric parts are connected by arranging the cut surfaces of the fiber bundles butt against each other, the connection state at the connection part is uniform, and moreover, the fiber bundles are not separated more than necessary. This eliminates the need for tightening and allows the oil to be sent smoothly through capillary action.
