    摘要： A shearing device (1) having a blade (2) with at least one blade cutting edge (5) which is helically coiled, and rotatable, about an axis of rotation (R) of the blade (2). The blade cutting edge (5) is assigned a counterpart blade cutting edge (4) of a counterpart blade (3). The shearing movements, by which for example bristle filaments (7) of brushes (8) for machining can be cut to length, are generated by relative rotational movement of the at least one helically coiled blade cutting edge (5) with respect to the preferably static counterpart blade cutting edge (4) of the counterpart blade (3). Since the blade (2) and the counterpart blade (3) can keep their spacing to one another constant during operation, there is a relatively low risk of injury during the use thereof.

    摘要： An end-rounding device comprises a movable body comprising an abrasive surface; a gearing for transferring a movement from a motor to the movable body; a providing unit for providing a plurality of bristle filament ends to the abrasive surface, wherein the providing unit comprises a clamping unit for clamping a bunch of filaments, wherein the bunch comprises a multiple of filaments of a bristle tuft; wherein the abrasive surface has a diameter from 80 mm to 300 mm and comprises a concave curvature oriented in the direction of the clamping unit; and wherein the clamping unit is movably spaced from the abrasive surface at a distance. A method of smoothening bristle filament ends utilizes the end-rounding device.

    摘要： A method for making toothbrushes includes the steps of, providing a toothbrush, and providing an end-rounder secured to a support. The support is substantially fixed against movement. The toothbrush is moved towards the end-rounder such that free ends of bristles secured to a head of the toothbrush are rounded by the end-rounder.

    摘要： A device for rounding the ends of plastic bristles on rotationally symmetrical circular brushes has a tool in the form of a rotationally symmetrical hollow body with an abrasive inner surface, which has an inner contour with an at least zonally smaller cross-section than the circular brush corresponding to the outer contour of the latter and between the circular brush and the tool there is a relative rotary movement and a reversible relative axial movement.

    摘要： A process and apparatus are provided for executing profiling trimming cuts in the bristle fields of toothbrushes. In order to process the fibers separately in different regions of the bristle field, and particularly to shorten them by means of a straight cutter or a level grinding disk, the fibers in the bristle field regions that are not to be contacted by the processing tool, are held at a distance from the processing plane of a processing tool by means of a lateral deflection of the free fiber ends in the longitudinal direction of the respective bristle field region. If the process is employed in several steps, in which respective fibers from various bristle field regions are to be processed, almost any desired profile cross-section can be created in the bristle field, not only in the longitudinal direction but in the transverse direction as well. Processing at each processing stage can thereby be accomplished with straight processing tools, for example with straight cutters. It is thus possible to dispense with the use of expensive profile cutters.

    摘要翻译： 提供了一种用于在牙刷的刷毛区域中执行轮廓修剪切割的工艺和装置。 为了在刷毛场的不同区域中分别处理纤维，特别是通过直刀或平面研磨盘来缩短纤维，不需要加工工具接触的刷毛区域中的纤维， 通过自由纤维端在相应刷毛区域的纵向上的横向偏转而保持在与加工工具的加工平面一定距离处。 如果在几个步骤中采用该方法，其中来自各种刷毛区域的各个纤维将被加工，则不仅在纵向方向上而且在横向方向上，在刷毛场中几乎可以产生所需的轮廓横截面，如 好。 因此，可以利用直线加工工具，例如用直刀来实现每个处理阶段的加工。 因此可以省略使用昂贵的型材切割机。
