A slitter rewinder machine is used to slit and rewind narrow rolls of web material such as paper, film, and foil. It consists of a rotating cutting drum, or slitter, and a rewind mechanism. The cutting drum has a number of knives mounted on it that are used to cut the web material into narrow strips. The rewind mechanism winds the strips onto separate cores.
Slitter rewinder machines are used in a variety of industries, such as the packaging, printing, and food processing industries. They are also used in the manufacture of tape, labels, and other narrow web products.
