An apparatus for manufacturing an individual brush unit constituting a rotary brush by being stacked in multiple layers, includes an anvil having an insertion hole through which a filament group passes, a filament feeding unit which feeds the filament group from a feeder including a ring cutter on a tip and holds the filament group while a predetermined amount of the filament group protrudes outward from the insertion hole of the anvil, and an ultrasonic welder including a horn having a horn tip portion which pushes and radially expands a protruding tip of the filament group and welds a central part of the expanded filament group, to form the individual brush unit. A core of the welded central part is sandwiched between the ring cutter and the horn tip portion and is cut out, to simultaneously form a shaft hole and separate the individual brush unit from the filament group.

A beauty apparatus according to the present disclosure includes a main body including a grip, and a brush part rotatably mounted to the main body. The brush part includes a first brush having a tuft of a plurality of bristles, and a second brush thicker than each of the plurality of bristles. A plurality of the second brushes disposed around a rotation center of the brush part is made greater in number than a plurality of the second brushes disposed along an outer circumference of the brush part. The beauty apparatus is capable of more uniform removal of dirt from skin.

An apparatus that cleans end surfaces of a substrate includes: a guide unit including a guide portion that has a channel, through which an end surface of a substrate passes, formed in a front surface thereof; and a brush with a front end whose position is controlled by a rear surface of the guide portion. The channel includes an opening that extends through the guide portion and the front end of the brush contacts an end surface of a substrate passing through the channel via the opening. The guide unit includes a concave portion in which at least the front end of the brush is housed and a suction hole that sucks dust from the concave portion.

A pool cleaning device for cleaning pools includes a tubular wand having a brush portion and a battery portion. The tubular wand incudes a first shaft telescopically coupled within a second shaft. A battery housing is affixed to the battery portion and a power source is positioned within the battery housing. A motor housing is pivotably attached to the brush portion such that the motor housing is movable between an upwardly angled position and a downwardly angled position. A motor is positioned within the motor housing. An output shaft is rotatably coupled to the motor. The output shaft extends outwardly from the motor. A bristle brush is removably coupled to the output shaft, wherein the motor rotates the output shaft, thereby rotating the bristle brush. Pivoting the motor housing pivots the bristle brush between the upwardly angled position and the downwardly angled position.

A brush (400) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (400) comprises a body (402) having a rotational axis (438). The body (402) comprises a first end (407), a second end (411), opposite the first end (407), and a channel (408), comprising an axial inlet (409) and an outlet (480). The axial inlet (409) is at the first end (407) of the body (402) and is coaxial with the rotational axis (438). The brush (400) also comprises bristles (420), extending from the body (402) so that the bristles (420) are not parallel to the rotational axis (438) of the body (402).

A brush (200) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (200) comprises a body (202), having a rotational axis (238) and comprising a first channel (208) that comprises an inlet (209) and a first outlet (280). The inlet (209) is coaxial with the rotational axis (238) and the first outlet (280) is offset from the rotational axis (238). The brush (200) also comprises tufts (222), extending from the body (202) and each comprising at least one bristle (220) and a tip (227). The brush (200) further comprises a first tube (210), communicatively coupled with the first outlet (280) of the first channel (208) of the body (202).

A tool for machining surfaces, edge regions, and contours comprising at least one disk-shaped base body rotatable around a tool axis and a plurality of flexible machining means, which are arranged on a circumference of the base body, wherein the machining means are formed rod-shaped and are arranged spaced apart from one another and extend substantially radially outward from the circumference of the base body, wherein at least two disks, between which the machining means are arranged, are arranged in the direction of the tool axis.
