What is a roller?

A roller is a cylindrical tool that is used to apply pressure or flatten and smooth out surfaces. Rollers come in various sizes and types depending on their intended use. Commonly used rollers include paint rollers, lawn rollers, and industrial rollers.

Paint rollers have a foam or nap material wrapped around a core, which is used to apply paint quickly and evenly on walls, floors, or ceilings. Lawn rollers are usually made of steel or plastic and are used to flatten and level out the soil or grass in a yard. Industrial rollers can be found in various widths and thicknesses to cater to different manufacturing processes such as printing, paper, textile, and metal processing.

Rollers can also be powered by electric motors or manually operated, depending on their usage. The invention of the roller dates back to ancient times when people used wooden logs or carved stones to flatten fields and roads. Today, rollers are widely used in many different industries and applications, making them an essential tool for many businesses.
