THE MAKING(English Version)(311)The Making of Toothbrushes and Toothpaste

This edition of the series of programs explaining the technology used to produce items that are familiar in our daily life features ‘Toothbrushes and Toothpaste’. A toothbrush is made by mounting fine nylon fiber bristles on to a handle. The bristles are then cut in a zigzag shape and their ends are rounded. The program introduces the whole toothbrush and toothpaste production processes, including packing and filling tubes with toothpaste. From start to finish, the products are never touched by human hand.
