    • PROBLEM TO BE SOLVED: To effectively utilize resources by a brush section replacing method in such a manner that not only a sleeve at the center in a brush is eliminated, but also, a conventional manufacturing method is changed to reduce the number of processes, and thus, the manufacturing cost is reduced, and the quality is stabilized and improved, and also, a structure without using an adhesive is adopted, and the tensile strength is increased, and the numeral variation is suppressed to the minimum in the manufacture of the brush part for hand piece.
      SOLUTION: One end surface of a yarn material group is molten, and pulled into a die molding small hole 4a which is installed on a die 4, and is molded simultaneously with welding. Then, after inserting a rod-like brush element 1 in a body shaft cylindrical circular hole, the external surface of the bottom surface is heated, and the bottom section of the rod-like brush element 1 is re-molded into a hinge shape by utilizing the heat conduction. Thus, the rod-like brush element 1 and the body shaft 2 are fixed, and this brush part for hand piece is manufactured. In another fixing method, a fixing small hole is installed on the external surface of the body shaft cylindrical circular hole, and after inserting the rod-like brush element 1, the side surface is press-fixed by a fixing part as a replacing method.

    • 要解决的问题:为了有效地利用刷部更换方法有效地利用资源,不仅消除了刷子中心处的套筒,而且改变了传统的制造方法以减少数量 工艺,因此制造成本降低,并且质量稳定和提高,并且还采用不使用粘合剂的结构,并且拉伸强度增加,并且数字变化在制造中被抑制到最小 手部的刷子部分。 解决方案:纱线材料组的一个端面熔化,并被拉入安装在模具4上并与焊接同时成型的模具成型小孔4a。 然后,在将杆状刷子元件1插入体轴圆筒形圆孔中之后,将底面的外表面加热,将棒状刷子元件1的底部再成型为铰链形状, 利用热传导。 因此,杆状刷子元件1和主体轴2被固定,并且制造了该手柄用刷部。 在另一种固定方法中,固定小孔安装在体轴圆柱形圆孔的外表面上,并且在插入棒状刷元件1之后,通过定影部件将侧面压固固定为替代方法。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a brush bristle material capable of simply manufacturing a high quality brush highly densely filled with bristles using a conventional bristle filling art and having superior cleaning property and texture, and a brush.
      SOLUTION: This brush bristle material and the brush using the same are characterized in being formed of a synthetic fiber bundle formed by joining synthetic fiber single yarns together with adhesive without twisting the plurality of synthetic fiber single yarns and opening it without sticking adhesive to at least one end of the synthetic fiber bundle.
