HookandLoop.com Installs Grommets in Straps

The service technicians at HookandLoop.com install grommets into straps. Grommets are small rings -- usually brass -- that are punched through any number of materials: paper, canvas, leather, etc. The purpose of these metal rings is to protect the surrounding material from damage when cords or strings are run through the hole of the grommet. Think of the rings your shoe laces are fed through, only stronger. If the rings weren't there, the material would eventually wear out and tear.

Various grommet sizes.

At HookandLoop.com, we use a MIC-5 semi-automatic electric grommet attaching machine that can attach all kinds of buttons, snaps, eyelets, grommets, jeans buttons, burrs, and rivets. This particular model has a laser light for precision and a safety guard for protection while loading the grommets. We are installing grommets into straps that are made of hook and loop and may be reinforced with polypropylene webbing. The machine is operated by a foot pedal, which when tapped, drives the grommet die down onto the partner die, compressing the two parts that comprise the grommet.

The grommet is made of two parts. One side is a flat circle with a neck extending from the inner circle, almost like the end of a tuba. This is the right grommet, or the front grommet. The combination of the dies and the grommet neck being compressed allows for the grommet to make a clean cut through the material, eliminating the need to cut a hole in the material beforehand. This is called a self-piercing grommet.

The other side is essentially a circle with no neck. This is the wrong grommet, or back grommet. The circle is domed or rounded for a smooth finish on the inside of the material. When compressed, the dies expand the neck and compresses it outward, wrapping the front grommet around the back grommet and securing it in place.
