Different Brushes for Different Needs.

Basic Constructions

Wire Drawn
This is a type of construction where the brush material is held in place by a continuos piece of wire. Instead of one pre-drilled hole as in a staple set brush there are two drilled holes. The larger of the two holes is for the fill material. The other hole is for the draw wire to go through. The back of a wire drawn brush looks as if the brush is sewn in place.


Staple Set
In this method, the brush material is held in place by a combination of the material stuffed into a pre-drilled hole and a staple. There are two types of staples. A "U" shaped type where round wire is used. The wire is cut and formed on the brush machine. This type of staple penetrates bellow the pre-drilled hole. The other type of staple is called a bar anchor. This is a flat piece of steel which penetrates the side of a pre-drilled hole and is used primarily for tooth brushes.

Trim Shapes

Flat
Most common shape used unless there are specific reasons for using other shapes.
Bevel
Reduces brush resistance and conforms to surface being brushed.
Concave
To conform to the surface being brushed.
Convex
To conform to the surface being brushed.
Step
For brushing irregular or uneven surfaces. Many variations are possible.
Double Bevel
To conform to the surface being brushed.
Combination Step
Combination of step trims to conform to the surface being brushed.
Chisel or Converging
Allows for greater concentration of brush fill to obtain more brushing action.

     


Fills Materials

Sizes and Colors Several fill materials are available and used in stapled brushes. Materials used are bristle:

  • horse hair
    goat hair
    tampico
    nylon
    polypropylene
    abrasive nylon
    brass
    carbon steel
    stainless steel
    phosphor bronze

Blends, various mixtures of fill materials used together, as are available as well.

Synthetic filament sizes range from .0025 to .060 and more while wire sizes range from .003 to .020. Filament type and sizes are determined by the application requirement. Filaments other than natural materials can be provided either crimped or straight (level) depending on application and requirements.

Synthetic filaments are generally black or natural (white) in color. However, synthetics are available in a wide range of colors.

Block Materials

A variety of solid block materials are used for practically any application and requirement. Blocks can be shaped to fit in practically any mounting or holding mechanism. Close tolerances can be maintained depending on the block material and requirement.

Most common materials are:

  • hard woods
    rubber
    aluminum
    leather
    molded or extruded plastics
    PVC
    Urethane
    Delrin
    Polypropylene
    Flexible PVC

Hole Patterns

An extremely wide variety of designs and densities are provided in stapled brushes to accomplish the desired effect for the application and requirement. The function of the brush and filament size determines the density and size of the tuft holes.

Patterns can be extremely dense to very open. Blocks generally bored straight, can be angled, flared, or converged to allow for specific trim shapes and to meet specific applications. Each pattern is specially designed for the application. Hole patterns can also be designed around mounting and fixture holes without affecting the function of the brushing action.
