A brush head (10) and a method (200) for manufacturing a brush head. The method (200) includes stamping (220) a plurality of openings (62) into a strip or roll of backing material (60). A bristle tuft (21) is inserted into each of the openings in the backing material. A proximal end (23) of each bristle tuft is bonded to a proximal side (63) of the backing material to create a merged proximal end head portion (26). Excess portions of the backing material are removed to form a plurality of carrier elements (24) about the openings from the backing material. The carrier elements form a plurality of merged tuft assemblies (20). A platen (42) of a neck (40) is positioned in relation to the merged tuft assemblies. A matrix material (30) is injected around the platen and the merged tuft assemblies to at least partially encompass the platen and the carrier elements of the merged tuft assemblies.

A cell of a brush making device for making at least a part of a toothbrush, having a pin unit having at least one pin, a pin holding sub-unit and a pin guiding sub-unit, the pin having a first section having a first end and a second section having a second end, the first section having a holding structure, and at least one spring section arranged between the first section and the second section, the pin holding sub-unit having a holding structure that is engaged with the holding structure of the pin for fixedly holding the pin, the pin holding sub-unit and the pin guiding sub-unit being arranged for being movable along a first direction towards and away from each other, and the pin guiding sub-unit having a channel for guiding at least a portion of the second section of the pin, the channel being inclined against the first direction.

Disclosed are a makeup brush and a manufacturing method thereof. The makeup brush includes a brush head and a brush handle. A bristle sheet is tightly bonded to an outer root of the brush head, and a height of the bristle sheet is less than that of the edge of the brush head. Therefore, in the process of makeup, the layering of bristles of the brush head and the outer bristle sheet is enhanced to make the brush more stylish, contributing to a more delicate makeup effect and an increased skin touching feeling.

The double action cleaning tool of the present invention includes a dynamic double action dual brush head and a handle. The dynamic double action dual brush head includes two brush heads rotatably attached to a brush head base, allowing the brush heads to independently rotate about the axis in which it is rotatably attached to the brush head base. A mechanical device capable of storing and releasing energy is connected between the two brush heads, which is rigidly attached to the brush head base. The double action cleaning tool stores energy in the form of potential energy in the mechanical energy storage device of the dynamic double action dual brush head during the sweeping stroke of the double action push broom. At the end of the sweeping stroke, the stored potential energy is converted into kinetic energy and rotates the dual brush, thereby providing an additional sweeping motion.

A brushroll dowel for a vacuum cleaner has a bristle stiffener protruding from a brush dowel. A plurality of stiffened bristles protrude from the brush dowel adjacent to the bristle stiffener, and a plurality of unstiffened bristles also protrude from the brush dowel and are non-adjacent to the bristle stiffener.

A personal-care applicator comprises at least one stem having a proximal end including a handle and a distal end opposite to the proximal end and at least one bristled component attached to the stem, wherein the bristled component comprises a carrier and a plurality of bristles ultrasonically welded to the carrier and outwardly extending therefrom according to a pre-determined pattern, wherein the elongated carrier and the at least first plurality of bristles comprise ultrasonically compatible materials, and wherein the bristles are ultrasonically bonded to the carrier through a direct ultrasonic bond between a surface of the carrier and a lengthwise portion of each of the bristles. Process comprises providing at least one elongated stem having a proximal end and a distal end, providing the at least one bristled component, and attaching the at least one bristled component to the at least first stem.

A filament-transportation device has a plurality of tube elements for transporting filaments from an intake area to an outtake area via an airstream generated by underpressure or overpressure. Each tube element has an end orifice. A baffle-plate unit has a baffle plate having a through-hole, a top surface opposite to the end orifices to stop the transport of the filaments, and a bottom surface opposite to the top surface. The baffle plate includes baffle plate elements associated with the end orifices. Each of the baffle-plate elements has a top surface forming part of the top surface of the baffle plate, a bottom surface forming part of the bottom surface of the baffle plate, and a side surface extending between the top and bottom surface. There is a plurality of bridge elements, each having a top surface forming part of the top surface of the baffle plate, a bottom surface forming part of the bottom surface of the baffle plate, and a side surface extending from the top surface of the bridge element to the bottom surface of the bridge element. The through-hole is defined either by the side surfaces of at least two baffle plate elements or by the side surfaces of at least one baffle plate element and of a side surface of at least one bridge element not facing an end orifice of a tube element, which bridge element connects two spaced apart baffle plate elements from the plurality of baffle plate elements.

A method (200) for manufacturing a brush head (10) includes: (i) positioning (210) a first end (23) of each of a plurality of bristle tufts (21) into a tuft plate (110) comprising a plurality of cavities (120) each configured to receive at least one of the plurality of bristle tufts; (ii) applying (220) a force, via a profile plate (300), to a second end (25) of the plurality of bristle tufts, wherein the profile plate comprises a predetermined shape complementary to a desired profile configuration of the bristle tufts; and (iii) applying (230) heat to each of the first ends of the plurality of bristle tufts, via a die plate (400) comprising at least one cavity (410) configured to receive at least one of the plurality of the first ends, at a temperature sufficient to at least partially melt each of the first ends into the cavity.
