Abstract:
A method and a device for manufacturing a rotary brush for roll tooth brush capable of easily removing plaque, providing an excellent massage effect on gums, capable of being mass-produced, and capable of reducing a cost by uniformizing the density of the bristles of the rotary brush (11), the method for manufacturing the rotary brush comprising the steps of projecting, by a specified amount, a wire group (1) formed of a large number of resin wires (1a) assembled together in a bundle to the outside through an insert hole (2a) provided in a pedestal (2), inserting a cone (4) to the projected tip center of the wire group (1) to push open the wire group (1) in radial directions, welding the center portion of the wire group (1) in an annular shape with the push-opened wire group (1) fixed onto the pedestal (2), cutting the inside of the welded part to form a sheet-like brush unit (8) having a hub (81) at the center thereof and having a large number of bristles (wires) (82) projected from the hub toward the radial outer side, holdingly inserting a core pipe (9) into the hub (81) of the brush unit (8), and taking out the brush unit (8) together with the core pipe (9) from the pedestal (2) to the outside.
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:
Device for compensating the vibrations caused by the movements of a tool of a brush manufacturing machine, more particularly of a tool (1) having at least one slide (2) which is provided in a first guide (3) such that is can move to and fro and which is provided with driving device (4) for this slide, wherein the device includes a compensating mass (16) and of a moving device (17) to move this compensating mass (16) in the opposite sense of the movement of the slide (2).

Abstract:
Device for handling brush bodies made of flexible material, characterized by the fact that it mainly consists of the combination of means for liberating brush bodies one at a time, means which punch holes in this brush bodies and means which maintain the brush body in the correct location during the punching of aforesaid holes; and means which maintain the brush body in the correct location during the filling thereof with fibres.
Abstract:
A brush-making machine comprising at least one rotatably mounted carrier member for chucking devices located on diametrically opposite sides of said carrier member, and possibly a depth compensating mechanism, said carrier member substantially having the form of a two-armed lever which carries the chucking devices at the ends of its arms.
Abstract:
Brush-manufacturing machine of the type equipped with a drum (1) for the transportation of the brush bodies (2) along the various processing stations, having the characteristic that the drum (1) is equipped with brush body holders (12-13-14-15) which at least at their clamping sides facing the brush bodies (2) can be revolved and/or removed from their respective sides with which they work in concert with the drum (1).
Abstract:
Brush filling apparatus comprising(a) longitudinally axially spaced rotary heads,(b) first structure to releasably couple three longitudinally extending brush cores to two of the heads, with the cores spaced about the axis,(c) second structure to rotate at least one of the heads about the axis, to rotate the cores between three index positions,(d) third structure to drill bristle receiving holes in a core at one of the positions,(e) fourth structure to fill bristles into the holes at a second of the positions, and(f) fifth structure to trim the filled bristles at a third of the positions.
Abstract:
The invention pertains to an automatic drum type machine for the manufacture of brushes, wherein the drum comprises at least two frames or workpiece holders, each carrying one or more brush holders proper, the various processing stations being disposed around said drum, characterized in that it comprises substantially the combination of means to impart the suitable width and length movements to the workpiece holders or brush holders situated in front of the drilling tools and in front of the filling tools, means to impart a compensation movement to the workpiece holders or the brush holders situated in front of the drilling and filling tools, or to the drilling tools and the filling tools, means to stop the workpiece holders or the brush holders situated in front of the filling magazines, in front of the shearing and cleaning device, and in front of other processing stations, during the said drilling and filling operation, and means to lock the various workpiece holders or the brush holders proper in their neutral positions during the rotation of the drum.
