<p>PURPOSE: A glass manufacturing apparatus is provided to improve constancy of cross-pulling tension and/or down-pulling sheet tension by using a tensile roll apparatus. CONSTITUTION: A glass manufacturing apparatus(201) comprises a melt container(207), a purification container(209), a mixing container(211), a transfer container(213), a molding apparatus(203), tensile roll apparatuses(215,217), and a separation apparatus(219). The molding apparatus manufactures a glass ribbon. The glass ribbon has a width extended from between a first edge part and a second edge part. The glass manufacturing apparatus additionally includes a control apparatus. The control apparatus independently operates the first tensile roll apparatus and second tensile roll apparatus. At least one pair of upstream tensile rolls rotates with a constant torque. At least one pair of downstream tensile rolls rotates with a constant angular velocity.</p> |
