    摘要: A method is provided for manufacturing a function element carrier with function elements, for example, individual tufts made up of bristles and/or massage elements, interproximal cleaning elements, or other elements designed to be fastened to a toothbrush and also perform special functions. The function elements are equipped at their ends intended for anchoring in a toothbrush with an anchor, retainer or axle element. The method includes: (a) inserting several function elements in corresponding recesses of an injection mold, said injection mold being connected via grid or bar shaped channels formed in a die to recesses in the areas of the anchoring ends of the function elements; (b) filling the grid or bar shaped channels with liquefied plastic material and injecting said material at the anchoring ends of the function elements or embedding them therein; and (c) allowing the plastic material to cool and removing a function element carrier made up of a grid or bar shaped plastic frame and the function elements. Function element carriers and toothbrushes are also provided.

    摘要: Methods are provided for determining the presence of cracks in razor blades during manufacturing. The methods may include, for example, providing a plurality of razor blades in a stack, inducing a current in the stack, and measuring a parameter that is related to the current and indicative of the presence or absence of cracks in the razor blades.
