摘要： The invention relates to a grinding device (1) which is used to machine the ends (14) of bristle filaments (15) of toothbrushes. The grinding device (1) comprises a grinding surface (8,9) which is provided with grinding elements (4) and along which the ends (14) of the bristle filaments (15) slide during the grinding process. Several grinding tracks (6,7) with various grinding elements (4) are provided on the grinding surface (8, 9). A compact grinding device (1) enabling various grinding processes to be performed either successively or side by side by means of various grinding surfaces (8,9) is thus produced.

摘要： The invention relates to a method for producing functional elements (5) to be used in a toothbrush, to corresponding functional elements and to a corresponding toothbrush. The first part of the invention relates to a method for producing functional elements (5, 9, 10, 12) consisting, for example, of individual tufts (5, 10) of bristles (15) and/or massaging elements (12), interdental cleaning elements (9), or other elements which are to be fixed to a toothbrush and also adopt certain special functions, said functional elements (5, 9, 10, 12) being provided with an anchoring, holding or axle element (13) on the ends (22) thereof which are to be fixed in a toothbrush. The inventive method comprises the following steps: a plurality of functional elements (5, 9, 10, 12) are introduced into corresponding recesses of an injection mould, said injection mould being connected, by means of latticed or rod-shaped channels formed in the tool, to the recesses in the region of the ends (22) of the functional elements (5, 9, 10, 12) which are to be fixed; liquefied plastic is injected into the latticed or rod-shaped channels and onto or around the ends (22) of the functional elements (5, 9, 10, 12) to be fixed; the plastic material is cooled and a functional element carrier (1) consisting of a latticed or rod-shaped plastic frame (2) and the functional elements (5, 9, 10, 12) is removed. The inventive method can be easily carried out at low cost and without high additional costs, and enables a plurality of functional elements (5, 9, 10, 12) to be handled in a simple manner, in one individual working step in a second part of the invention. A toothbrush which is produced according to one such method is economical and has a simple structure according to a third and fourth part of the invention.

摘要： A clamping device (1) for holding a plurality of bunches of filaments (2, 3, 4) pertaining to a field of bristles arranged on the head of a toothbrush. The clamping device (1) comprises fixed and moveable clamping elements (8, 9, 10, 17, 18, 19, 20) provided with continuous holes (7, 12, 13) which are used to pass said bunches of filaments (2, 3, 4) through the two planes of said clamping elements and which are aligned with each other when the clamping device (1) is in a non-actuated state and are offset in relation to each other when the clamping device (1) is in an actuated state, in order to clamp the bunches of filaments (2, 3, 4) cross-wise in relation to the longitudinal direction of the filaments and to hold them. The invention is characterised in that several moveable clamping elements (8, 9, 10), which are displaceable in relation to the fixed clamping elements (17, 18, 19, 20), are provided in the clamping device (1). Each of the moveable clamping elements (8, 9, 10) is provided to respectively hold another part of the bristle field. The invention also relates to a method for holding a bundle of filaments by means of a clamping device with at least two clamping elements. According to said method, the bundles of filaments are effectively prevented from undesirably slipping out of the filament feeder device and from being damaged as a result of an excessive clamping force.

摘要： A transport carrier (1) for precise-positioned supply of small parts (12) which can only be sorted with difficulty, especially plastic parts, characterized in that a flat transport strip (2) is provided with stamped receiving and fixing openings (3) for receiving positioning and jointing aids (4) arranged on said small parts (12). The invention also relates to a method for supplying small parts which can only be sorted with difficulty, especially small plastic parts, to a placement station, comprising the following steps: provision of positioning and jointing aids (4) which are connected to one or several small parts (12); securing the positioning and jointing aids (4) in the receiving and fixing openings (3) of a transport strip (2) by jointing or cold deformation; transferring the small parts (12) to the placement station via the transport carrier (1); precise-positioned removal of the small parts (12) from the receiving and fixing openings (3); and returning the transport carrier (1) to the supply circuit. The invention provides a reusable transport carrier for precise-positioned supply of small parts which can only be sorted with difficulty, enabling corresponding reductions to be made in the transport carrier and tool costs. The invention also enables the carrier strip to be fitted with interchangeable mould bars outside an injection moulding machine, thereby enabling waste parts to be sorted before despatching.
