MAHATMA roller feeder is a device used to feed and transfer materials such as paper, cardboard, plastic film, and other thin, flexible materials. It consists of a series of rollers that are driven by a motor or other power source, and they work together to move the material forward at a consistent speed. The rollers are typically made of rubber or other non-slip materials to ensure that the materials being fed do not slip or get stuck. Roller feeders are commonly used in printing and packaging industries, as well as in the manufacturing of various products that require the transfer of thin, flexible materials.
