Abstract
A pillow filling apparatus includes an enclosed housing having an inlet chute for receiving polyester fiber material used as stuffing for the pillow. A pair of pincher rollers feed the fiber material into the housing, and a large fine-toothed roller is mounted adjacent the pinchers such that roller teeth pull and loosen fibers being fed by the pinchers. The large roller rotates at a speed great enough to throw the fibers from the roller into an air chamber. A fan is mounted to one side wall of the housing and produces an air current which is introduced into the air chamber of the housing through an inlet portal and exits the housing through an outlet portal. Fibers thrown by the roller into the air chamber are carried by the air current out of the housing through the outlet portal. A pillow tick is located at the outlet portal of the housing to receive the loosened and fluffed fiber materials.
