Device for producing strip

A glass manufacturing apparatus includes a delivery tube terminating at a lower end in a delivery slot. A flow of molten material is delivered along a plane of travel in a direction of travel. The first plate is positioned proximate the lower end of the delivery tube on a first side of the plane of travel. The first plate includes a first edge extending proximate the plane of travel and a first thermal expansion slot extending from the first edge to the first interior. A second plate is positioned proximate the lower end of the delivery tube on a second side of the plane of travel. The second plate includes a second edge extending proximate the plane of travel and a second thermal expansion slot extending from the second edge to the second interior. The second edge is spaced from the first edge to define a delivery opening through which the delivery tube extends. 本发明公开一种玻璃制造装置，包括终止于递送狭槽中的下端处的递送管。在行进方向上沿着行进平面递送熔融材料流。第一板在行进平面的第一侧上定位在递送管的下端附近。第一板包括延伸于行进平面附近的第一边缘及从第一边缘延伸到第一内部的第一热膨胀狭槽。第二板在行进平面的第二侧上定位在递送管的下端附近。第二板包
