えられている。(Prior art and its problems) In order to improve the precision of the top needle, conventionally, a thermoplastic synthetic resin layer was provided between the back side of the top clothing and the top bar clothing pasting surface, and the A method has been considered in which the needle height is made uniform by heating and softening the thermoplastic synthetic resin layer while pressing the needle head against a surface plate.

つた。 However, in the case of the above method, the heat-softened synthetic resin layer flows through the gap between the crown, the back surface of the base fabric, and the top bar's clothing attachment surface, but if the accuracy of the top bar's cloth attachment surface is extremely poor, It was difficult to sufficiently fill low spots. Therefore, if the top was attached to a carding machine and used for a long time, the accuracy of the needle height deteriorated.

成するものである。(Embodiment 1) FIG. 1 shows an embodiment of the top of the present invention. A thermoplastic material containing a foaming agent, such as polyamide, polyester, EVA, polyvinyl chloride, polyethylene, polypropylene, etc., is placed between the back surface of the top clothing 1, which has a uniform needle head surface, and the clothing pasting surface of the top bar 2. A foamed resin layer 3 formed by foaming and filling a synthetic resin or a thermosetting synthetic resin containing a foaming agent such as phenol resin, urea resin, polyurethane, etc. by heat conduction from the needle tip is provided, and the top clothing is 1. The foamed resin layer 3 and the top bar 2 are fixed by side clips 4 to form the top of the present invention.

Glue. Next, as shown in FIG. and the top clothing 1 are assembled together. Next, as shown in FIG. 4A, a far-infrared heater 8 is provided at a certain distance from the needle head surface 7 of the top clothing to irradiate the needle head surface 7 with far-infrared rays.

ラウン１０の温度をより急速に上昇させる。 FIG. 4B is an enlarged partial cross-sectional view of the top. As shown in the figure, the heat of the needle head surface heated by absorbing far infrared rays is conducted to a large number of needles, and the temperature of the crown 10 on the back side of the base fabric increases more rapidly.

A foamed resin layer 3 is formed that fills the gap between the top bar attachment surface and the back surface of the base fabric.

便利である。 Note that it is convenient to adhere a thin non-adhesive sheet 12 to the foamed resin layer on the top bar attachment surface 5 when reattaching the top clothing using the top bar.
次に、第４図ハに示すように、表面が高精度に
平滑に加工された定盤１３に、上記トツプの針頭

る。 Next, as shown in FIG. 4C, the needle head surface 7 of the top is pressed against a surface plate 13 whose surface has been processed to be smooth with high precision, and the needles are cooled with the needle heights aligned.
なお、冷却は放冷でも強制的に冷却させてもよ

い。 At this time, the softened and foamed resin layer generates pressure between the clothing attaching surface of the top bar and the clothing.
Since the top bar is held at a constant distance from the surface plate, its pressure presses the back of the top clothing against the surface plate. Therefore, the needle head surface of the top clothing is in close contact with the surface of the surface plate, and the gap between the back surface of the top clothing and the top bar clothing surface is completely filled with synthetic resin and cooled. Even if the top bar is removed, the needle precision maintains the precision of the surface plate. Note that heating with a far-infrared heater may be performed with the top clothing surface facing upward, but for the purpose of placing the top clothing on a surface plate, it is preferable to place the heater below with the clothing surface facing downward.

を構成する。(Example 2) As shown in FIG. 5A, a thermoplastic synthetic resin layer 6 is formed by applying a thermoplastic synthetic resin that foams upon heating to the top clothing attaching surface 5 of the top bar 2. A top clothing 1 is attached to a top bar 2 and fixed with side clips 4 to constitute the top of the present invention.

いることも可能である。 In addition, in the above embodiment, the thermoplastic synthetic resin layer that foams when heated is on the back side of the top clothing.
It is provided by gluing a foamed thermoplastic synthetic resin sheet or by applying a thermoplastic foaming synthetic resin to the top bar's top needle cloth attachment surface. It is also possible to insert a foaming synthetic resin sheet or to attach the sheet to the base fabric of the top clothing and to insert needles into the top clothing to form the top clothing.

可能である。 Furthermore, methods for softening and foaming the synthetic resin layer include heating the surface plate and top bar from the outside using methods other than far infrared rays, induction heating only the synthetic resin layer using high-frequency radio waves, or induction heating together with the top bar. This can also be done by heating.

る。(Effect of the invention) As described above, the present invention achieves high needle accuracy without polishing the needle heads of the top clothing after attaching the top clothing to the top bar, so there is no need to impair the performance of the top. Even if the top bar and top clothing have poor accuracy, it is extremely easy to obtain high accuracy on the top needle head surface. No longer needed.

考案である。 Also, when the synthetic resin layer softens, it foams,
It does not become hard like a non-foamed synthetic resin layer, but has elasticity due to air bubbles.Furthermore, because the needle is heated faster than the base fabric, the synthetic resin layer in contact with the crown foams significantly, making it possible to grip the crown elastically. Because there are
Even if a load is applied to the needle tip due to the carding action, no large stress is generated on the needle, deformation of the needle is reduced, and fiber breakage is also reduced. In addition, the foaming does not reduce the thickness of the synthetic resin layer, and even if the top bar is severely distorted due to the pressure of foaming, it will adhere completely to low places and completely fill the gap between the top bar and the back of the top clothing. A non-adhesive sheet is interposed between the top bar's needle cloth attachment surface and the foamed resin layer. Therefore, the top clothing can be easily removed even when replacing damaged top clothing, and since the top bar is also clean, the top clothing can be easily reattached, making this a highly practical idea. .
