Title:
METHOD FOR TAPERING THE BRUSH OF A TOOTHBRUSH BY A MECHANICAL METHOD
Document Type and Number:
WIPO Patent Application WO/2010/050671
Kind Code:
A2
Abstract:
The present invention relates to a method for tapering the brush 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 a 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 brush to pass through each of the grinding drums in series such that the brush can be ground. The method of the present invention produces highly tapered brushes having a tapered length of 5mm or longer and an end thickness of 0.02mm or less even without immersing brushes into chemicals, and prevents thermal deformations which may otherwise occur in the tapering process performed by a mechanical method.
