Definitions
- the invention relates to a method according to the preamble of claim 1.
- profile-shaped sleeves for the production of brushes, which, with an essentially cylindrical shape, have a curved bottom corresponding to the free end of the finished brush.
- profile sleeves can be used for single and small series production, but are not suitable for large series production.
- Brushes especially high-quality brushes, are still largely manufactured by hand.
- pig bristles and synthetic bristles are used for paint brushes and household brushes
- special natural bristles are used for artist brushes.
- Badger, weasel or marten hair are also suitable. Care must be taken to ensure that the high-quality hair or bristles (for badgers, weasels or martens, the price per kilo is up to DM 20,000) are processed practically without loss.
- the brush hair or bristles are combed in a first step
- the bristles aligned in this way are combined into bundles of bristles of the desired extent and are largely further processed by hand in accordance with the current state of the art.
- an upwardly tapering filler piece - usually made of cork - is introduced into the center of the bristle bundle, as a result of which a cavity is created in the interior of the bristle bundle, which serves on the one hand as a reservoir for the mass or color to be spread and for others have the task of reducing the amount of bristles required and of securing the cord pre-strip.
- This reduction in the bristle material in the interior of the bristle bundle has no disadvantages, since the bristle ring which is created in this way widens anyway at some distance from the border in such a way that the circular ring (in cross section through the bristle bundle) becomes a closed circle again. On the other hand, a circular ring would also suffice to spread the paint and would have no really disadvantageous consequences.
- a so-called “preliminary strip” is also provided for paintbrushes, which can be removed almost continuously step by step, so that the brush is free even after the bristle bundle has worn out In the end it can be used further by removing (cutting off) the pre-strip piece by piece.
- a preliminary strip usually consists of a helical wrap around the part of the bristle adjacent to the brush head.
- REPLACEMENT LEAF fret ice with a twisted cord The individual spiral layers are given the necessary support among one another by knotting, gluing or in some other way.
- the painter then removes one or more layers of the helix mentioned, for which - as already mentioned - a special twisted cord is usually used.
- the head of the bristle bundle with the filler mentioned above is held together using a suitable binding compound, which is also referred to as "putty", and is connected to the brush head, which consists of a lid and a handle.
- a suitable binding compound which is also referred to as "putty”
- the cover and stem are put on either after the two components have been connected beforehand, or subsequently, one after the other.
- assembly must first be carried out with the lid; in the case of double-conical stems, both variants are possible.
- the invention has for its object to provide a method according to the preamble of claim 1, which ensures a uniform quality of the product with increased output irrespective of manual skills of a person.
- REPLACEMENT LEAF 1 shows the basic structure of a brush according to the invention
- FIG. 2 shows a basic illustration of a device for dividing the bristle bundle in order to enable the introduction of a filler into the bristle bundle and
- FIG. 3 shows a basic illustration of a device for cutting filler pieces from the continuously supplied material.
- the most important component of a brush is the bristle bundle 10 (or hair bundle). This is provided with a centrally located filler 11 in the course of production. Subsequently, the brush head formed from the filler 11 and the bristle bundle 10 surrounding it is shaped with a concave top surface if necessary. As a result, the initially flat upper end 12 of the bristle bundle 10 is formed into a depression 13. The other, free end 14 of the bristle bundle 10, also called the bristle tip or bristle flag, is inevitably given a convex shape. Other designs are also conceivable.
- the above-mentioned concavely shaped upper end 12 of the bristle bundle 10 is filled with a hardenable binding compound 15, the so-called "putty", which also partially penetrates into the upper part 16 of the bristle bundle 10, solidifies it and also an intimate connection between the bristle bundle 10 and the filler 11.
- a substance based on a curable epoxy resin with an oily to pasty consistency is preferably used as the binder.
- the binder 15 must be in the
- the putty also serves to connect the previously described brush head to the lid 17 and brush handle 18.
- the handle of the brush can be single or double conical. In the first case there is a uniform conical course over the entire length of the handle, in the second case the brush handle 18 tapers on both sides starting from a point approximately at the height of the sleeve 19 of the cover 17 to be attached to it later
- the previously mentioned cover 17 is connected to the brush handle 18 and produces the outer end of the bristle bundle 10 and the transition to the brush handle 18 in the finished brush.
- the individual steps of the method for the mechanized or automated production of a previously described brush are explained below. Reference is made to FIG. 2 for explanation.
- the bristle bundle 10 of the desired size is gripped in a suitable device and held hanging.
- two or more separating slides 22 move radially towards the center 23 of the bristle bundle 10.
- These separating slides have an essentially knife-like shape and, with their blunt "cutting edges", lie essentially on a radius of the bristle bundle 10. They can - if two such separating slides 22 are present - also on the "cutting side" with each complementary L-profiles can be provided which interlock. In the case of a larger number of such separating slides 22, these can possibly also extend slightly beyond such a radius and be slightly offset in height in relation to one another.
- REPLACEMENT LEAF 22 are expediently arranged at a uniform angular distance from one another.
- a plurality of separating slides 22 can also be provided, which then, as shown in FIG. 3, create a plurality of openings for a plurality of packing elements 11, which as a material 28 are continuous (continuous or quasi-continuous) from one or more Rolls are deducted.
- the cross-sectional area of the upper edge 12 of the bristle bundle 10 - if there is a desire - can be deformed by fitting a corresponding profile part in such a way that a concave shape is created.
- This design on the upper edge 12 of the bristle bundle 10 creates a convex shape of the bristle bundle 10 at its lower end 14, as is required or desired in practice.
- E RSA TZBLATT Binding compound 15 entered after a ring, preferably made of plastic or a nickel-iron connection (in the case of paintbrushes), was placed on the top of the bristle bundle 10, and finally the brush handle 18 and Cover 17 formed unit put on. After the putty has hardened, the brush is basically finished.
- the hardening of the binding compound 15 (of the cement) should also take place in the production unit.
- the finished brushes are temporarily stored in a powder magazine in a device with a corresponding secured holder, for example on pallets with guide elements for bristle bundles 10 and brush handles 18.
- the curing time is about one to two hours.
- the buffer magazine must therefore have a corresponding storage capacity.
- Paintbrushes with a metal ring can also be machined.
- the cover 17, which is preferably made of plastic, is provided on its outer circumferential surface, i.e. where he later contacts the metal ring, evenly distributed over the circumference, three vertical bars.
- These preferably conical webs enable the cover 17 to be introduced more easily into the cylindrical metal ring.
- the brush cover, and thus also the brush handle 18 connected to it, is adequately held until the binder 15 hardens via the webs mentioned, which ensure a snug fit or a slight press fit of the cover 17 in the metal ring. The previously existing risk that the brush handle 18 tilts relative to the brush head is thus eliminated.
- paintbrushes have a support.
- the place of the later opening act is initially taken by a second ring, a so-called auxiliary ring.
- this second ring the auxiliary ring
- the complete removal of the auxiliary ring, which is necessary after the cement has hardened, can also be done mechanically.
- the preliminary strip 24 is then attached. It preferably consists of a twisted cord, which is wound helically around the bristle bundle 10 below the first ring and solidified in itself by means of suitable connecting means, such as knots, glue or the like.
- the preliminary strip 24 can be removed step by step by the painter, which ensures a sufficient free length of the bristle bundle 10 even when worn at the lower edge of the bristle bundle 10.
- the filler 11 can be introduced into the bristle bundle 10 in the manner described above.
- the use of an auxiliary ring is omitted here, since household brushes are manufactured with a plastic ring, in which only an imitation of the preliminary strip is injection molded onto the ring instead of the preliminary band.
- the filler 11 which in addition to cork, can also consist of other materials such as wood, plastic or cardboard and. also from
- the cutting is preferably carried out with a counter-rotating double knife 25, 26 specially developed for this purpose with a counterhold 27 for the filler 11 (FIG. 3).
