A sheet feeder, which is configured to feed a sheet to a processing machine, includes a main body, a cutting unit, and an attaching portion. The cutting unit is attached to the main body and includes a cutter slidable in a first direction. The cutting unit is configured to cut, along in the first direction, the sheet to be fed to the processing machine with the cutter. The attaching portion is configured to attach the main body to the processing machine. The attaching portion is attachable to the shaft of the processing machine.

A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.

A printer includes a first blade configured to be movable between a standby position and a cutting position, a second blade configured to contact the first blade located in the cutting position, a drive mechanism configured to drive the first blade, and a first elastic member configured to pull the first blade located in the cutting position. When the first blade is located in the cutting position, the first elastic member pulls the first blade in a direction in which the first blade moves to the standby position, and pulls the first blade in a direction in which the first blade approaches the second blade.
