rotating cylinder in machines or devices
A round part that turns in a machine or tool and helps move, press, or massage something as it rolls over it.
Padrão de uso:
a roller moves [material] through [machine]

Sinónimos
cylinder (General shape word; does not always imply that the object turns or is part of a machine.)
Antónimos
slider (A component that moves by sliding rather than by rolling.)

A very heavy round tool that you roll over the ground to make it flat and smooth.
Padrão de uso:
