Beschreibung
Zusammenfassung:	A method of manufacturing a glass ribbon is provided. The method includes providing a first pull roll device (28) located in a draw zone (140) of the glass manufacturing apparatus. The first pull roll device (28) draws a glass ribbon from a forming device. A second pull roll device (30) located in a catenary zone (60) of the glass manufacturing apparatus is provided downstream from the first pull roll device (28). The second pull roll device (30) comprises a first pull roll apparatus (110) to support weight of the glass ribbon and a second pull roll apparatus (112) with drive rolls to support weigh of the ribbon. The device (30) isolates tension of the glass ribbon in the draw zone from a free loop of the glass ribbon that is downstream of the catenary zone.
