Machine Drawing Cylinder Sheet Glass

æsheet of glass is drawn vertically through a debiteuse a refractory block.

Machine drawing cylinder sheet glass.

This machine was able to draw glass from its molten state into sheets. Histoglass offers genuine machine drawn glass with both our thin double glazing and our mono single glazing systems. At the beginning of the twentieth century the machine cylinder method was introduced. Although glass cylinders could be drawn by machine they had to be opened and flattened by hand.

The glass was annealed and then cut into 7 10ft cylinders which were then cut lengthways reheated and flattened. A circular metal bait about 25 cm 10 in in diameter situated at the end of a blow pipe was lowered to the surface of the molten glass. This was an improvement over the machine cylinder process as it removed the surface imperfections created by the flattening of the sheets and also took out the unwanted green tint. The first mechanical method of drawing glass 40 ft high cylinders of glass were drawn vertically from a circular tank.

Machine the mass of glass on the blowing iron is prepared as in the case of drawing by hand. Fourcault sheet draw process æthe modern sheet glass process was first developed by fourcault circa 1914 in belgium. Machine drawn glass is ideal for properties constructed in the early to middle twentieth century. Even beyond the victorian era the age of a property determines the most authentic glass type to use in replacement glazing.

Cylinders of glass 40 feet 12 m high are drawn vertically from a circular tank. In 1901 belgian glassmaker emile fourcault invented a machine that drew a glass sheet five stories straight up from a vat of molten glass. These are cut lengthways reheated and flattened. This process was used in the uk up to the end of the 1920 s.

What was needed was a way to form sheets of glass directly and continuously. High in the basement of which is a motor driven winding drum. Machine drawn cylinder sheet was the first mechanical method for drawing window glass. Cylinder blown sheet glass was manufactured in the uk in the mid 19th century.

Welcome to huihua china uniqueness and finest vertical machine draw restoration glass from 1900 s it features less distorting and exhibits mild waviness occasional seeds or defects now there isn t this kind of technology in the world early vertical machine drawing already update to neat sheet glass and float glass by modern technology while we still keep traditional methods of fourcault. Using compressed air for blowing it was possible to draw a cylinder of glass approximately 1500 cm 50 ft high. The glass was drawn vertically in a flat sheet until it cooled sufficiently to allow the glass to be cut. The glass is then annealed and cut into 7 to 10 foot 2 to 3 m cylinders.

The drawing machine is installed in a tower about 170 ft.
