A method of manufacturing a brush includes providing a core wire section having a proximal end and a distal end, and an integral tip on the distal end, forming a bristle element having a throughbore, and inserting the core wire section into the throughbore until the bristle element is received on the core wire section.

In one embodiment, the present invention provides a buffer brush. When rotating, the buffer brush acts as a centrifugal pump. The buffer brush contains a core having a first side and a second side and the brush extends racially from the surface of the core. The first and second sides have at least one opening configured to allow air to flow laterally through the core. Vents on the surface of the cure are configured to allow air flowing laterally through the core to also flow radially through the vents into the brush.

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.

A vehicle treatment brush is provided for washing and/or polishing purposes in a vehicle treatment installation, including a support part having a longitudinal extent and defining a pivotal axis, a plurality of brush segments arranged axially next to each other and each including cleaning elements, and a drive device, wherein at least one brush segment includes a pivoting device with a rotary body on which the cleaning elements of the brush segment are indirectly or directly held and which is in operative connection with the drive device for driving the rotary body about a rotational axis of the brush segment that is different from the pivotal axis.

A vehicle treatment brush for washing and/or polishing purposes in a vehicle treatment installation is provided, including a support part having a longitudinal extent and defining a pivotal axis, a plurality of brush segments arranged axially next to each other and each including cleaning elements, and a drive device, wherein at least one brush segment includes a pivoting device with a rotary body on which the cleaning elements of the brush segment are indirectly or directly held and which is in operative connection with the drive device for driving the rotary body about a rotational axis of the brush segment that is different from the pivotal axis, wherein the support part is non-driven and the rotary body is pivotable about the pivotal axis relative to the support part by way of the pivoting device. The present invention also relates to a vehicle treatment installation.

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.

The device is for cleaning the inner surface of a pipe. The device has a spindle arranged to be rotated and having a front end and a rear end between which a plurality of elastic metal blades are attached both in the rotation direction of the spindle and in the direction perpendicular to the rotation direction to clean the inner surface of the pipe. The blades has a shape that is curved at at least two points such that they curve at least once towards the circumferential direction of the spindle and at least once outwards from the circumferential direction of the spindle to prevent the device from getting stuck in uneven pipe systems.

A modified honing brush is provided comprising one or more bristles and one or a plurality of reusable stackable plates having one or more holes or voids located in the plates, or one or more support guides, and wherein each of the bristles is independently fitted through one or more of the holes or voids of the plates or surrounded by one or more support guides.

A sonic vibration toothbrush includes a head extending in an axial direction with a plurality of bristles implanted at an outer circumference thereof in a direction perpendicular to the axial direction; a head arm having an inner space to transmit a sonic wave to the head. A top portion of the head arm where the inner space is narrowed is coupled to the head and a motor accommodating portion that accommodates a motor therein and transmits a sonic wave generated by a rotating force of the motor to the head arm. The toothbrush further includes a handle having a space for accommodating a battery; an input unit provided at the motor accommodating portion in a button form; a display unit provided at the handle; and a control circuit that controls the motor according to input information provided from the input unit.

The invention provides a brush bristle and a brush roll that exhibit a suitable abrasive force and that can reduce or eliminate the abrasion of a mill roll as much as possible. The brush bristle is for use in a brush roll B configured to scour a mill roll for rolling a metal sheet S, and includes one or more monofilaments 2 made of a thermoplastic resin containing abrasive particles. The abrasive particles have a hardness lower than the hardness of the mill roll, and higher than the hardness of the metal sheet S.
