Abstract:
A brush, in particular for household or industrial applications, has a bristle carrier plate made of plastic, a multitude of bristle bundles, which are attached in the bristle carrier plate, and at least one reinforcement plate, which is likewise made of plastic and is attached to the bristle carrier plate.
Abstract:
Device for manufacturing brushes by means of successive operations, which mainly consists of a number of brush holders (9-11) which are provided on a means of transport and which can be moved between different posts (5-8) which are provided along the means of transport, more particularly working posts (6-8) where a processing can take place and/or waiting posts (5) where the brush holders (9-11) can be put in a wait position, characterized in that the means of transport is provided with means which make it possible to move the brush holders (9-11) independently from one another.
Abstract:
Method for manufacturing brushes includes providing fiber bundles (4) in a support (2); moving the fiber bundles (4) according to a desired profile until they protrude through openings (21) in a holder (10) with one far end; and anchoring the fiber bundles (4) in the holder (10), wherein moving the fiber bundles (4) in the support (2) is carried out according to an intermediary profile; the fiber bundles are shortened to a desired length; and the fiber bundles (4) are moved further until they extend through the openings (21) in the holder (10) according to the desired profile.
Abstract:
Method for manufacturing brushes, whereby, on one hand, fibers (3) are supplied to at least one filling tool (4) by means of at least one auxiliary device (15) comprising at least two fiber loading chambers (16-20) and, on the other hand, said fiber loading chambers (16-20) are replenished by taking up fibers (3) from at least two respective fiber supply channels (8-12), whereby, by means of the filling tool (4), the fibers (3) are inserted into brush bodies (6), wherein, on one hand, the supply of the fibers (3) from the fiber loading chambers (16-20) to the filling tool (4) and, on the other hand, the replenishing of the fiber loading chambers (16-20) with fibers (3) from the fiber supply channels (8-12) is realized by means of working cycles which as such are independent.
Abstract:
In a method of melting together axial ends of bunched fibers of thermoplastic material, the fiber ends are brought into contact with the heated surface of a stamp. The body of the stamp is heated by controlling an electric current passing through it. In one embodiment the stamp is cooled by a flow of compressed air before the stamp is separated from the fiber ends. In another embodiment, the stamp is separated from the melted fiber ends, heated to a higher temperature to vaporize any residual fiber material, and cooled by exposure to compressed air until it has no more than the temperature for melting the fiber material.
Abstract:
Method for manufacturing brush bodies for tooth brushes, in particular for injection moulding brush bodies (2) consisting of at least two components (5-9), of the type whereby at least one first injection moulding piece (25) is formed of a first component (5) in a first mould (3), consisting of at least two mould parts (4-6); whereby at least one second injection moulding piece (26) is formed by providing the first injection moulding piece (25) in a second mould (7), which also consists of at least two mould parts (8-10), and by providing a second component (9) on the first injection moulding piece (25) in the second mould (7); and whereby every injection moulding piece (25) formed in the first mould (3) is transferred to the second mould (7) by a transfer part (1 5) provided between the mould parts (4-6-8-10) of the above-mentioned moulds (3-7), characterized in that the injection moulding pieces (25) formed in the first mould (3) are secured to the transfer part (15) during the transfer to the second mould (7) for at least part of this movement by a securing mechanism (40) which can be activated.
Abstract:
A brush making machine with a mold for injection molding of brush bodies is disclosed. The mold includes a stationary mold part, a movable mold part and a pair of complementary mold parts fitting into a recess of the movable mold part. The complementary mold parts have tuft insertion holes. While one of the complementary mold parts fills the recess of the movable mold part and a brush body is injection molded with tufts of bristles embedded in the molding material, the other complementary mold part is in front of a tuft feeder for introducing tufts of bristles into the tuft insertion holes. The tuft feeder includes a plurality of tuft picking and transfer tubes which are movable to pick out tufts of bristles from a bristle container and to transfer each of these tufts to a position adjacent one of the tuft insertion holes. Plunger members penetrate into respective tubes to push out the tufts of bristles contained therein and to force them into and through the tuft insertion holes.
Abstract:
A bristle insert, in particular for a brush, is formed by at least one bristle pack having a plurality of plastic bristles whose ends are fused to each other to form a self-supporting holding element. A brush with such a bristle insert, and a method for manufacturing such a bristle insert is also provided.
Abstract:
A paint brush has a handle, a bristle carrier plate fixed directly to the handle, and a plurality of bundles of bristles inserted into the bristle carrier plate through receiving openings.
Abstract:
A method of producing, by injection molding, a hollow cylindrical syringe body which is provided with a scale applied in the longitudinal direction. The scale is applied to a thin carrier film and the carrier film with the scale is inserted into the injection mold prior to the injection molding process.
