A method of making a brush includes providing a plurality of first filaments, each having a first end and a second end; bringing the plurality of first filaments into a first predetermined shape such that the first ends are arranged side by side on a common contour; fixedly connecting the first ends so that a first pre-tuft having the first predetermined shape and a connected first end is formed; bringing a second tuft element having a first end and a second end together with the first pre-tuft into a second predetermined shape such that the first end of the second tuft element and the connected first end of the first pre-tuft are arranged side by side on a common contour; fixedly connecting the connected first end of the first pre-tuft and the first end of the at least second tuft element so that a final tuft having the second predetermined shape and a connected end is formed; and attaching the final tuft to a brush body by overmolding the final tuft's connected end with a plastic material.

Provided is disclosure for hybrid material post-CMP brushes and methods for forming the same. Embodiments of a hybrid material post-CMP brush may comprise at least two layers, where the hybrid brush is used to clean various surfaces, such as surfaces of semiconductor substrates. An example hybrid brush for cleaning a surface includes a mandrel, a molded first layer formed about the mandrel, where the molded first layer comprises a first material, and a molded second layer surrounding the molded first layer, where the molded second layer comprises a second material.

An applicator device including at least one holding section, at least one working tip, and a neck section connecting the holding section and the working tip, the device also includes a base body formed at least partially from a first plastic component, the base body being at least partially overmolded by at least one second plastic component that is softer than the first plastic component. In the region of the working tip, the at least one second plastic component at least partially coats the base body, and the coating includes outwardly projecting, bristle-type cleaning elements.

The present invention concerns a method of bundling a plurality of monofilaments into a bundle of monofilaments by means of a laser, a paint brush head including such bundle of monofilaments and a paint brush including such paint brush head.

A bottle brush cleaning implement that uses a crochet scrubber component and an integrated handle and its method of assembly. The preferred embodiment of the crochet component has four brushes that are constructed out of one piece of crochet material that is attached and is held in place with a pronged holder with resistance barbs. The crochet component is additionally held in place by extra yarn that is attached to the bottom of the crochet scrubber and tied to the handle. The preferred embodiment's handle has a grip area with a series of round protrusions to improve handling. The bottle brush may be produced on a wide variety of shapes, colors, sizes and configurations to meet specific needs or individual preferences.
