Sheet manufacturing apparatus

Abstract

A sheet manufacturing apparatus includes a buffer tankthat stores a material containing fibers; a defibratorthat defibrates the material supplied from the buffer tankand discharges the fibers; a mixing unitthat mixes the fibers and a binding material binding the fibers to each other and discharges a mixture; a first transport beltthat transports the mixture; an accumulation unitthat accumulates the mixture on the first transport beltto form a web W; a second transport beltthat comes into contact with one surface of the web W to transport the web W; processing rollersandthat pressurize the web W; a cleaning unitthat removes and recovers residual fibers adhering to the first transport belt; and a fiber transport pipethat transports the residual fibers recovered by the cleaning unitto the defibrator
