The present invention relates to a toothbrush having needle-shaped bristles on the head portion and is configured in such a manner that the differences in height between the longer bristles and the shorter bristles is 1 to 4 mm, the end points of the longer bristles are 0.01 to 0.03 mm in diameter, the end points of the shorter bristles are 0.03 to 0.08 mm in diameter, the taper lengths of the longer bristles are 4 to 8 mm, the taper lengths of the shorter bristles are 2 to 6 mm, and the differences in taper length between the longer bristles and the shorter bristles is 1 to 4 mm. The toothbrush according to the present invention provides the superior teeth and gum contact force unique to a toothbrush having needle-shaped bristles and at the same time also provides superior cleaning performance for the surface of teeth thanks to the action of the shorter bristles having relatively large diameters at end points and relatively short taper lengths. In addition, the wearing-out of an end portion of the bristles is delayed thanks to the shorter bristles so that the effect of prolonging the lifespan of the toothbrush is provided.

Verfahren zur Verarbeitung von Faserbündeln, wobei Faserbündelabschnitte von einem Faserbündel abgeschnitten werden, wobei Faserbündel mit einer Zuführungsvorrichtung zugeführt werden. Ein Faserbündel wird in seinem oberen Bereich von einem oberen Greifer ergriffen und das Faserbündel wird in seinem unteren Bereich von einem unteren Greifer ergriffen. Anschließend wird das Faserbündel unterhalb des unteren Greifers von einem Vorschubgreifer ergriffen und daraufhin öffnet der untere Greifer. Im Anschluss daran wird das Faserbündel mit dem daran angeschlossenen oberen Greifer und dem daran angeschlossenen Vorschubgreifer um einen Hub nach unten vorgeschoben, der der Länge eines von dem Faserbündel abzutrennenden Faserbündelabschnittes entspricht. Daraufhin wird ein Faserbündelabschnitt mit einer Schneideinrichtung von dem Faserbündel abgetrennt. Anschließend wird der untere Greifer wieder geschlossen sowie der Vorschubgreifer geöffnet und der Vorschubgreifer wird wieder nach oben zurückbewegt. Im Anschluss daran wird der untere Greifer wieder geöffnet sowie der Vorschubgreifer wieder geschlossen und das Faserbündel wird mit dem daran angeschlossenen oberen Greifer und dem daran angeschlossenen Vorschubgreifer wieder um einen Hub vorgeschoben und so weiter fort.
摘要:
Bristle stiffness is varied by allowing a support beam (22, 66, 80) that carries the bristles (54, 55, 68, 82, 84) to undergo torsional movement in response to brushing action. Torsional movement is achieved by allowing the support beam to be disconnected to the brush head along at least portions of the length of the support beam. In particularly preferred embodiments, brushes employing the varying stiffness techniques are made with bristle sub-assemblies that have at least one row of bristles connected to a base string or similar structure that functions as a support beam. The base string can be connected across an opening in the brush, and is thus connected at its opposite ends, or it can be connected at any number of spaced intervals, the number and length of spacing being selected to achieve a desired degree of stiffness.

In order to apply mascara and comb the eyelashes, the invention proposes carrying out a selective, clean and adaptable cutting of the bristles twisted along a core by selecting some of the bristles located, along the wire, in angular sectors of adjustable amplitude and by continuously cutting the bristles thus selected at a predetermined height.The implementing guiding module has a guiding inlet head (69a) and a cylindrical tube body (69c), the head being for bristles remain curved. The cutting (70) and guiding (45) groove formed by an end piece with a conical outline extended by a hollow tube having a central channel (31) of the same diameter, cutting (70) and guiding (45) grooves being formed in the channel. The cutting grooves (70) are distributed longitudinally in order to select the brush bristles to be left untouched, alternating with grooves (45) for guiding brush bristles to be protected from being cut, the cutting grooves (70) forming, in the tube body, cutting slots (57) and guiding grooves (45) having a depth such that the selected grooves form indentations (45a, 75a) on the end of the end piece. The present invention is mainly applicable to the cosmetic industry.
