Brush

The term brush refers to a variety of devices mainly with bristles, wire or other filament of any possible material used mainly for cleaning, grooming hair, make up making painting, deburring and other kinds of surface finishing, but also for many other purposes like (but not limited to) seals, alternative traction systems and any other use imaginable for this tool.

In the industry it is possible to find many configurations such as twisted in wire (like the ones used to wash baby feeding bottles), cylinders, disks (with bristles spread in one face or radially) or in any other shape needed. There are many ways of setting the bristle in the brush: the most common is the staple or anchor set brush, in which the filament is forced with a staple by the middle into a hole with a special driver and held there by the pressure against the walls of the hole and the portions of the staple nailed to the bottom of the hole. The staple can be substituted with a kind of anchor, which is a piece of rectangular profile wire that, instead of nailing itself to the bottom of hole, is anchored to the wall of the hole, like in most toothbrushes. Another way to set the bristles to the surface can be found in the fused brush, in which instead of being inserted into a hole, a plastic fiber is welded to another plastic surface, giving the additional advantage of optionally using different diameters of tufts in the same brush, and a considerably thinner surface (sometimes the bristles can be set this way to the outer surface of a plastic bottle).citation needed]
