Apparatus for separating a glass sheet from a moving ribbon of glass

摘要

Disclosed are methods for compensating the varying weight of a glass ribbon the glass ribbon is drawn from a molten glass forming material, and an apparatus therefore. The weight compensating apparatus is configured to apply a force to the glass ribbon that is inversely proportional to the weight of the glass ribbon such that as the glass ribbon weight increases, the force applied to the glass ribbon by the weight compensating device decreases.

主权项

1. An apparatus for producing a glass sheet comprising:
a forming body for forming a continuously moving glass ribbon from a molten glass; a scoring device positioned below the forming body configured to score the continuously moving glass ribbon in a widthwise direction of the continuously moving glass ribbon; a weight compensating apparatus configured to apply a downward force to the continuously moving glass ribbon, the weight compensating apparatus comprising; a conveyor; a linear drive unit; an engaging device coupled to the conveyor via the linear drive unit and configured to travel along the conveyor in a draw direction of the continuously moving glass ribbon, the engaging device comprising a suction cup configured to contact and engage with edge portions of the continuously moving glass ribbon.
