Description

[Detailed Description of the Invention] The present invention relates to an improvement of an insert cap for indicating the type of thread used in a flanged bobbin.

Generally, when weaving is carried out by winding yarn onto a flanged bobbin using a reeling machine or winding machine, and by attaching a creel to a warping machine or loom, it is necessary to clearly classify the type of yarn wound on the bobbin. , it is necessary to prevent the mixing of different types of yarns.

For example, in the manufacturing process of tire cord blind weaving, when the input raw yarn is wound around the bobbin and passes through each process, oil-based paint is applied to the flange of each bobbin to prevent yarn of other types from getting mixed in. Color classification is done by applying organic paint, etc., but these require application of organic solvent when changing the color.
In addition, the different colors to be colored were not clear, and the number of tones used was small, making it unsatisfactory for the preparation of a wide variety of yarns.

For this reason, by using an insert cap 1' which is made up of a circular cylinder 3' fitted to a colored resin disc 2' which is inserted into the center hole of the flange bobbin and fixed to the flange, the colors of the yarn can be clearly distinguished. However, the conventional insert cap was able to solve the sanitary problem caused by organic solvents when changing colors, but as shown in Fig. 1, the cylindrical body 3' of the insert cap 1' inserted into the center hole of the bobbin was Since the hole diameter becomes small due to the wall thickness, when replacing the bobbin when the bobbin is fully doffed, insert the first joint of your middle finger into the hole in the cylindrical body 3' of the insert cap 1', and insert the other finger into the hole of the insert cap 1'. There was a drawback that it was difficult for the middle finger to enter the hole in the cylinder 3 during the operation of hooking and pulling out the flange of the disc 2'.

In order to eliminate these drawbacks, the present invention provides an insert cap in which a notch having an appropriate length and width is cut downward from the upper end of the cylindrical body.

The embodiments of the present invention will be explained with reference to the drawings.
is an insert cap, which has a colored synthetic resin disc 2 on its upper part, and a circular cylindrical body 3 whose outer diameter is the same as the central hole of the bobbin in the center of the disc 2, protruding downward. It is integrally formed. Reference numerals 4 and 4 denote vertically long finger insertion notches cut downward from the upper end of the circular cylindrical body 3, which have an appropriate length and are wide enough to accommodate the first joint of the middle finger. It is provided on the opposite surface of the.

As shown in FIG.
The disc 2 is made of colored resin, and the disc 2 is made of colored resin to distinguish the different types of yarn.
In addition, when replacing the bobbin when the bobbin B is fully doffed, insert the first joint of your middle finger into the vertically long finger insertion notch 4 provided in the cylinder body 3 and insert it into the wall of the center hole of the bobbin B. At the same time, the other hand is placed on the flange of the disc 2 to remove the full bobbin.

As described above, the present invention has a cylindrical body 3 having the same diameter as the central hole of the bobbin protruding downward from the center of the colored synthetic resin disk 2, and a vertically elongated cylindrical body 3 extending downward from the upper end of the cylindrical body 3. Since this relates to an insert cap for a flange bobbin characterized by having cut-out openings 4 for inserting fingers in the shape of opposite sides cut out, the vertically long cylindrical body 3 provided in the cylindrical body 3 of the insert cap when doffing a full bobbin. The middle finger can be inserted smoothly into the shaped finger insertion notch 4, and even if the first joint of the middle finger is bent, it will not hit the inner wall surface, so it is easy to apply force and the thumb can be easily inserted into the disc flange of the insert cap. The tube bobbin can be removed and carried.
