摘要:
Geräte zum Auftragen fluider Medien weisen zu Bündeln zusammengefaßte Borsten (1) aus Kunststoff auf, die an einem Borstenträger (6) aus Kunststoff durch eine thermische Schmelzverbindung derart festgelegt sind, daß innerhalb des Bündels (1) mindestens ein sich zu den Borstenenden (3) verjüngender Kanal (4) gebildet wird, der eine im Borstenträger (6) angeordnete Austrittsöffnung (5) für das Medium bis in den Bereich der Borstenenden (3) verlängert. Solche Geräte werden dadurch einfach und kostengünstig hergestellt, daß ein an die Austrittsöffnung (5) anschließendes und in den Kanal (4) im Borstenbündel (1) hineinragendes Steigrohr (7) durch thermisches Aufschmelzen und Umformen der Borsten (2) und/oder des Borstenträgers (6) erzeugt wird.
摘要:
Method of making brushes for cleaning preferably bacteria-polluted surfaces, particularly the skin, gums or teeth, in which the body (1) of the brush shall be provided with a great many bristles (2) designed to collectively form a uniformly distributed bristle covering on the brush body (1) or parts thereof. To apply the bristles (2) to the brush body (1) in a very rapid and solid manner even though the body and the brush are very small, a surface (3) of polyamide material of the brush body (1) is supplied with a water-soluble organic acid (8) to dissolve the brush body surface (3) of polyamide material, whereupon bristles (2) of preferably polyamide material are attracted to the brush body (1) by electrostatic attraction so that those end portions (17) of each bristle which come in contact with the dissolved surface (3) of the brush body (1) are dissolved and caused to fuse with said surface to form a brush in which the body (1) and all bristles (2) are integrated into a unit. A brush product particularly suitable for dental care, which has been produced by this method, has a body (1) comprising an end portion (1a) devoid bristles to permit being grasped during brushing without coming in contact with the bristle-carrying parts of the body (1).
摘要:
A method of forming a brush from a plurality of thermoplastic bristle filaments (30). The steps of the method include inserting the plurality of thermoplastic bristle filaments (30) into a hollow mold tube (22), moving a hole former pin (52) into a first end of the bristles, and heating the mold tube (22) adjacent the first end of said bristles to melt the first end of the thermoplastic bristle filaments around the pin. The steps also includes cooling the mold tube (22), extracting the first end of the filaments out of the mold tube (22) and extracting the pin (52) out of the first end of said bristle filaments, whereby a brush having a hollow brush holder (32) is formed for use.
摘要:
A method of making rotary driven brushes, particularly road-sweeping brushes, by arranging bunches of bristles (2) so that their one ends (2a) extend into a mould (3) for forming the brush base (1), and applying into the mould (3) around the ends (2a) of the bristles a quick-setting liquid plastics material, generally a micro-cellular elastomeric polymer material such as polyurethane foamed by adding water thereto, and allowing the plastics material to set to secure the brush base to the bristles.
摘要:
A method of manufacturing brush components is disclosed wherein an array of bristles (1) which may either be loosely arranged in which case they should be substantially aligned or may be in the form of a knitted or woven tape is overlain by a membrane (3) e.g. a polythene or polypropylene sheet, the bristles and membrane then being bent through 180° about the centre line of the array into a generally U-shaped configuration and subsequently held in that position by clamping means e. g. a metal channel (7) or an extruded plastics beading (9). Preferably a strengthening wire (5) is located over the top of the membrane and within the U at the base thereof.
摘要:
La présente invention concerne une tête (4) de brosse à dents (1), comportant une base (12) rigide destinée à coopérer avec un manche (2), pour assembler la tête (4) à ce dernier de manière amovible, et un organe nettoyant (14) solidaire de la base (12) et comprenant une pluralité d'éléments flexibles nettoyants (16), la base (12) comprenant un trou (34) destiné à recevoir une languette de stabilisation (22) portée par le manche (2) de brosse à dents, l'organe nettoyant (14) étant déformable de manière élastique et étant réalisé d'un seul bloc par surmoulage de la base (12), et comprenant une butée de stabilisation (46) positionnée dans le prolongement du trou (34), ou au moins partiellement à l'intérieur du trou (34), de manière à pouvoir être comprimée par la languette de stabilisation (22) lorsque la tête (4) est assemblée au manche (2).
