Staple Brushes Fill Material

Tanis offers a variety of filaments to be used in stapled set brushes including synthetics, natural bristle and wire. The type of material selected will depend upon the desired characteristics. Fill may be stiff or soft, thick or thin, repel or absorb water, chemical or heat resistant, flexible to a greater or lesser extent, and resistant to bending or abrasion.

Other filament characteristics include brush density and bristle length. Choosing a crimped filament, instead of a level or straight filament will provide you with a more dense brush appearance and a continuous more even brushing action. The crimp is measured by amplitude, depth of the crimp, frequency and number of crimps per inch. Level or straight bristles provide a lesser brush density appearance. The measurement of the exposed filament is known as the trim length and is the working strength of the brush.

The filament or tuft diameter can range from, but is not limited to .078” up to 7/16”. The depth of the tuft holes will determine the block or core wall thickness required. Generally, the tuft holes are drilled and filled vertically, but depending on the application, the hole can be drilled and the filament inserted at either a flared or converged angle.

The brush filament is trimmed in the final processing stage to give the required shape.

Trim styles available are:

• Flat is the most common shape used unless there are specific reasons for using other shapes.
• Bevel reduces brush resistance and conforms to surface being brushed.
• Concave conforms to the surface being brushed.
• Convex conforms to the surface being brushed.
• Step is used for brushing irregular or uneven surfaces. Many variations are possible.
• Double bevel conforms to the surface being brushes.
• Combination step is a combination of step trims conforms to the surface being brushes.
• Chisel or converging allows for greater concentration of brush fill to obtain more brushing action.
