Staple Brushes Design Specifications

Hole Pattern and Design

Using the latest in machining technology, stapled set brushes can be designed and manufactured in virtually any hole or tuft pattern to produce a desired density and brush pattern. Our automated stapling machines can read CAD programs without requiring endless hours of programming on the machine. Small quantity and single tufted patterns can also be manufactured on a semi-automatic or hand machine.

The two most common hole patterns for flat stapled set brushes are a straight or staggered pattern but two additional patterns, spiral (helical) and chevron (herringbone), are available for rotary stapled set brushes. A spiral or herringbone pattern is used to orient product in a specific direction or used to give a specific brushing effect.

Core Constructions

Solid block and core materials most commonly selected are wood and plastics including polyvinyl chloride (PVC), polypropylene, high-density polyethylene (HDPE), ultra-high molecular weight (UHMW), ABS and delrin. Flexible materials like soft, flexible polyvinyl chloride and urethane are also available. These backing materials allow the bending and contouring of the brush around a corner or radius.

Staples

The staple shown in the illustration is a primary part of the brush. A staple is made either of steel, stainless steel or brass. The type of staple is predicated by the environment and conditions the brush will be performing under.

Hole or Tuft Diameter

The individual hole or tuft diameter can range from, but not limited to, .078” up to 7/16”. The hole depth depends on the diameter of the hole or tuft diameter. The hole depth will help determine the block or core wall thickness required for the brush design. Generally the tuft holes are drilled and filled vertically. Depending on the application, the hole can be drilled and material inserted at an angle. The material can be angled in two ways either flared or converged.
