The Auto Sheet Feeder simplifies the bulk cutting process by automatically loading sheet materials into your Silhouette cutting machine. Place up to 20 sheets of material into the top tray and set the number of copies to be cut in Silhouette Studio®. Then, the Auto Sheet Feeder loads each sheet into the cutting machine and ejects it below the loading tray or behind the cutting machine for a seamless, matless cut job. Cut the same design multiple times, or send different cut jobs at the same time using barcodes. The Auto Sheet Feeder is compatible with the Silhouette Portrait® 3 and Cameo® 4.
