2. Description of the Related Art Conventionally, polishing a surface such as an automobile body or the like after painting or a lens surface of a camera or the like (hereinafter referred to as a body surface, etc.) which requires a strict smoothness by surface finishing. For example, soft natural furs such as moutons are often used.

[0003] However, the one using this fur or the like,
It has disadvantages such as inferior supply stability and high cost. In view of the above drawbacks, soft knitted fabrics in which fine denier synthetic fibers are knitted by various knitting machines to form a pile loop have been proposed.

[0004]

However, in the conventional knitted fabric 400, as shown in FIG. 13, only one ground thread 310 and one pile loop 300 are formed in one course. Have the following disadvantages. By polishing the surface of the body or the like, the pile loop 300 is liable to be so-called (the pile loop is collapsed and the bulkiness is reduced). When sewing is performed with a sewing machine or the like as necessary, the ground thread is broken by the sewing machine needle, and the tensile strength and the like of the knitted fabric are easily reduced.

Accordingly, the present invention has been devised. The object of the present invention is to polish a body surface and the like by having two or more pile loops as compared with a case having only one pile loop. An object of the present invention is to provide an apparatus for manufacturing a knitted fabric in which the pile loop is hard to set when the sewing machine is used and the ground thread is broken by sewing of a sewing machine or the like.

[0006]

Means taken by the present invention to achieve the above object will be described below with reference numerals used in the drawings corresponding to the embodiments. Immediate Chi, as shown in FIG. 4 or FIG. 5, the configuration of the knitted fabric manufacturing apparatus according to claim 1, a knitted fabric manufacturing apparatus having a "two or more different heights the pile loops of the ground yarn Above the yarn feeder 21, yarn feeders 22 for two or more pile yarns are provided corresponding to the number of the yarn carriers 20 provided at different heights, and the number of the yarn feeders 22 for the two or more pile yarns. And a sinker 40 having a sinker nose 30 having different heights.
The contents.

[0007]

According to the above-described means, the knitted fabric manufacturing apparatus 200 according to the first aspect of the present invention, as shown in FIG. 4 or FIG. Supply port 22 for two or more pile yarns 12
Are provided at different heights, so that pile yarns 12 having two or more different heights together with the ground yarn 11 can be supplied to the same course at once.

The ground yarns 11 and the two or more pile yarns 12 supplied from the yarn carrier 20 are provided with sinker nose portions 30 having different heights provided in correspondence with the number of yarn supply ports 22 of the two or more pile yarns 12. Sinker 40 having
As shown in FIG. 6, the yarns are simultaneously knitted by the needles, and the ground yarns 11 and the pile loops 10 having two or more different heights are formed.

The yarn carrier 20 is provided with a yarn feeder 22 for pile yarns 12 having two or more different heights above a yarn feeder 21 for the ground yarn 11 and a sinker 4.
0 has a sinker nose 30 having a different height corresponding to the number of yarn supply ports 22 of the pile yarn 12.

As shown in FIGS. 1 to 3, a knitted fabric 100 manufactured by the manufacturing apparatus 200 has a pile loop 1 having two or more different heights on the same course and on the same wale.
Since 0 is formed, the pile loop has a larger number of pile loops, so that the number of pile loops is large, so that the durability against deformation due to external force and the like are large.

When the knitted fabric 100 is sewn as required by a sewing machine or the like, even if the ground thread 11 is cut, the pile loop 10 is hard to cut. Therefore, this 2
The tensile strength and the like of the knitted fabric 100 on which the pile loops 10 are formed are larger than those with one pile loop.

The pile loops 10 need to have two or more different heights in order to increase the durability against deformation due to an external force. Increases, and apparently, the pile loop 10 surface tends to be hard. In other words, the purpose of this is to adopt a synthetic fiber such as fine denier or conjugate to polish the body surface, etc., where sharpness and smoothness of surface finish are strictly required, so that the purpose of finishing the pile loop surface is softened. Will be rejected. Furthermore, forming a large number of pile loops 10 is not preferable in terms of workability and stability of the apparatus during operation. Therefore, the number of pile loops 10 is 2 to 4
A degree is desirable.

Similarly , two to four sinker nose portions 30 of different heights in the sinker 40 corresponding to the number of the yarn feeders 22 and the yarn feeders 22 of the pile yarns 12 having two or more different heights in the yarn carrier 20 are provided. Is desirable.
