Bristle holder with handle anchoring
'' Manufacturing process for finsel

The invention relates to a completely beuartigen bristle carrier which with a number of different assembly parts, which in turn Systematically put together a unit according to the respective requirement. The manufacturing process of brushes is using this bristle carrier unit is significantly simplified, the durability of the brush is significantly increased.

The previously known bristle carriers in round or oval shape are always a fit such as a ring or capsule in which the bristle material is pressed against the wall of the socket by driving a conical stem, giving the bristles a firm seat. In this process, the bristle material must be given a certain pre-pressure. This is done by rubbing sand or similar material between the bristle heads (roots), which requires the filling material to be evenly distributed. Uneven distribution or too much filling will deform the socket when the handle is driven in. In addition, the handle sits at an angle and must then be straightened, which caused additional work. The handles must be smoothly prepared before driving in, which is done by ingrowth. After driving in, the stems must be cleaned again by washing or grinding. In most cases, bristles are pulled back when the handle is driven in and have to be cut off again afterwards. In the last two cases mentioned, additional overtime is created. Other manufacturing processes are known in which the bristles are again firmly seated by rubbing them with sand or the like or by means of a plug which must be inserted centrally between the bristle heads. By pouring a brush resin that penetrates into ate bristle heads, a core is created after hardening, which in most cases shrinks (shrinks). The stem is held in place in further infusion compound, or with the additional use of a washer or lid. A firm, intimate anchoring with the bristles is not guaranteed and the total weight of the brush is increased by the infusion compound. The bristle carriers on Flaohpinsel are made of sheet metal. The bristles are inserted into these, either enough bristle material that a certain tight fit is achieved or, if there are fewer bristles, a filler piece such as wooden strips or cardboard is placed between the bristle heads. usually nooh is connected to the sheet metal with wire pins.

Through the slit end of the Handle holder sleeve, the handle is pushed in until the inner ringS approach of the handle holder sleeve engages in the groove of the handle, both is now inserted into the conical bore of the assembled lower and upper = part is printed up to the approach 7, the center piece is pressed in and the Unit is ready. The stems stay clean and are always straight and firm.

When using a handle made of plastic 13 or wood with attachment 1ο if the inner ring attachment is omitted, the sleeve does not need to be slit.

4. Upper part with handle or handle in any shape from one piece Made of plastic 18 is made with lower part 16 by mutual Toothing 17 assembled and also form a finished unit
