The invention provides for an improved article of manufacturing, being a utility brush that is designed to be made from material that minimizes abrasion to surfaces. This brush is made from materials excluding metal and other materials that can cause abrasion to surfaces upon the utility brush making physical contact with those surfaces. The utility brush being further designed to be made of material that excludes adhesives, where adhesives can be vulnerable to decomposition caused by physical contact with chemical solvents that could be applied to the utility brush or to the surfaces. The brush can be further dimensioned and/or customized, to brush surfaces located within oddly dimensioned and/or difficult to access spaces, including small and/or narrow spaces and crevices.

A device used in the technical field of producing bristle products. The device (1) includes a tufting tool (3) for tufting bundles of bristles (4) into a provided bristle carrier (5) and a bristle displacer (6) for displacing already tufted bundles of bristles from a tufting region of the tufting tool (3). The tufting tool (3) and the bristle displacement element (6) are connected to a common drive shaft (9) of the device via a respective coupling gear mechanism (7) and/or (8) and are driven by same.

A method for producing a toothbrush head comprises providing at least two bristle tufts that differ in at least one property; arranging the tufts in a hole-perforation plate comprising holes shaped and distributed according to the desired bristle field; arranging an energy source so that the ends of the bristle tufts and the energy source are arranged contactless, wherein the ends of the bristle tufts to be fused are arranged at different distances to the energy source and are adjusted according to the different property; applying energy to the ends of the bristle tufts until fuse balls are formed; transferring the bristle tufts to a subsequent process position, wherein the distance of the fuse ball of at least one bristle tuft to the hole-perforation plate is different from the distance of said fuse ball to the hole-perforation plate in the fusing position before; over-molding of the fuse balls of the bristle tufts with plastic material thereby forming the brush head or the part (10) thereof.

A brush head (32) including: a supporting portion (42) of a brush neck (40); a plurality of bristle tufts (21), each of which comprises a plurality of bristle strands having a proximal end (23) and a free end (25), wherein each of the plurality of bristle tufts comprises a proximal end head portion (26) melted into a first shape within a mold; and an elastomeric matrix (30) comprising at least a portion of the hard brush neck and the proximal end head portions, wherein the first shape of the proximal end head portion is configured to engage the elastomeric matrix such that the bristle tufts are retained within the elastomeric matrix.

A tuft picker for a tuft-picking device has a working surface having a tuft-picking notch with a depth, a width, and an opening. First and second projections reduce the opening of the notch versus an inner width. At least one top of the first and/or second projection is located off-site the working surface of the tuft picker and inside of the notch. A distance from the at least one top to the working surface of the tuft picker is in the range of from 0.05 mm to 0.5 mm, and an angle between the working surface of the tuft picker and a line of reflection symmetry crossing the at least one top is from 1 to 45.

An environmental-friendly paintbrush without bristle-implanting holes includes a handle, a bristle-implanting brush head, and a metal plate. The bristle-implanting brush head may have one end provided with a bristle material-laying trough, and another end connected with the handle. A plastic block may be placed inside the bristle material-laying trough. Bristle material may be filled in an interstitial space between the plastic block and the bristle-implanting brush head. The plastic block is formed with a metal-laying trough. The metal plate is set inside the metal-laying trough. Two ends of the bristle material-laying trough are formed with metal slots provided inside the brush-implanting brush head. Two ends of the metal plate are slotted into the metal slots. A method of processing an environmental-friendly paintbrush without bristle-implanting holes is also disclosed.

A bristled tool head and a method of fabrication thereof, the method comprising molding a shell having a top surface and a bottom surface, the bottom surface comprising a pattern of housings, the housings being selectively localised and inclined relative to a direction normal to a plan of the shell depending on a position along a length and across a width of the bottom surface; finishing the housings of the as-molded shell into sockets; and securing tufts of bristles within the sockets.

The embodiments of the present disclosure provides a brush manufacturing machine (100) comprising a rotary transportation mechanism (160); a bristle carrier loading station (110); one or more bristle dispensing station (120a-d) comprising a bristle feed mechanism (200), a bristle tuft picker (240), and a bristle plant feeder (250), that plants high-density and short length bristle tufts on a bristle carrier (170) with fine pitch openings; an ultrasonic fusion station (130); a heating station (140); an unloading station (150); and a logic controller system for providing programmed commands, controlling the machine sequence and monitoring the feedback of operating conditions at every station through a network of sensors and actuators.
