Under-Machine Repulpers

Most paper and board machines are equipped with at least three under-machine repulpers. These repulpers collect and process wet and dry broke from the machine during normal operation and also during startups and sheet breaks. The three most common under-machine repulpers are located under the couch roll, press section, and reel. Some machines have another repulper located under the winder. This modules describes the purpose, locations, and components of under-machine repulpers.
