Abstract

본 발명의 치솔대(4)는 치솔모(40)를 수용하기 위해 외향 연장하는 동심원 칼러(6)에 미리 형성된 구멍(5)을 포함한다. 치솔대(4)에 고정된 각 치솔모내 치솔모(41)는 두꺼운 고정 단부(42)를 형성하도록 용해된 고정 단부를 갖는다. 각 치솔모(40)의 두꺼운 고정 단부(42)는 미리 형성된 구멍(5)의 대응 단면과 치솔대(4)사이에 외향 연장된 칼러(6)보다 크지 않는 단면을 가진다. 미리 형성된 칼러(6)와 치솔대(4)내 미리 형성된 구멍(5)의 인접 측벽부(8)는 비접촉시 수단에 의해 연화되며, 치솔모(40)의 두꺼운 고정 단부(42)는 미리 형성된 구멍(5)과 연관 칼러(6) 아무런 간섭없이 그 사이에 삽입되고, 연화된 칼러(6)는 치솔모(4)의 두꺼운 고정 단부(42)주위를 스웨이징되여, 스웨이징된 칼러(6)가 냉각되어 굳어질 때 치솔대(4)에 칫솔모(40)가 고정된다. 칼러(6)는 단지 적은 양의열가소성 물질만을 포함하기 때문에, 연결 효과를 내는데 필요한 가열과 냉각을 최소화하여, 전체 제조 시간을 줄인다. 특히, 칼러(6)내 국부적으로 작은 가열은 치솔대(4)의 눈에 거스리는 손상 또는 비틀림을 피한다.
