Title:
機械的方法による歯ブラシ用毛材のテーパー加工方法
Document Type and Number:
Japanese Patent JP5603874
Kind Code:
B2
Abstract:
The present invention relates to a method for tapering bristle of a toothbrush using grinding drums which have protrusions (11) with a height of 1.5 to 7.0mm, and which rotate in the vertical and horizontal directions, said method comprising a step of connecting the grinding drums in parallel, such that the grinding drums are arranged in sequence wherein the heights of the protrusions (11) of each of the grinding drums are gradually decreased, and a step of enabling the toothbrush with a non-tapered bristle to pass through each of the grinding drums in series such that the bristle can be ground. The method of the present invention produces highly tapered bristle having a tapered length of 5mm or longer and an end thickness of 0.02mm or less even without immersing brisle into chemicals, and prevents thermal deformations which may otherwise occur in the tapering process performed by a mechanical method.
