Machine Drawing Cylinder Sheet Glass

Fourcault sheet draw process æthe modern sheet glass process was first developed by fourcault circa 1914 in belgium.

Machine drawing cylinder sheet glass.

At the beginning of the twentieth century the machine cylinder method was introduced. Histoglass offers genuine machine drawn glass with both our thin double glazing and our mono single glazing systems. 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 early 20th century marks the move away from hand blown to machine manufactured glass such as rolled plate machine drawn cylinder sheet the fourcault process of flat drawn sheet single and twin ground polished plate and most common float glass. This machine was able to draw glass from its molten state into sheets. Cylinder glass machine draw processes the logical evolution was to draw a flat sheet rather than a cylinder. The first mechanical method of drawing glass 40 ft high cylinders of glass were drawn vertically from a circular tank.

The drawing machine is installed in a tower about 170 ft. A steel wire rope connected to the drum runs straight. 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. Machine the mass of glass on the blowing iron is prepared as in the case of drawing by hand.

The glass was annealed and then cut into 7 10ft cylinders which were then cut lengthways reheated and flattened. Although glass cylinders could be drawn by machine they had to be opened and flattened by hand. In 1901 belgian glassmaker emile fourcault invented a machine that drew a glass sheet five stories straight up from a vat of molten glass. Cylinder blown sheet glass was manufactured in the uk in the mid 19th century.

Cylinders of glass 40 feet 12 m high are drawn vertically from a circular tank. Machine drawn glass is ideal for properties constructed in the early to middle twentieth century. What was needed was a way to form sheets of glass directly and continuously. This process was used in the uk up to the end of the 1920 s.

æsheet of glass is drawn vertically through a debiteuse a refractory block. Using compressed air for blowing it was possible to draw a cylinder of glass approximately 1500 cm 50 ft high. 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. Machine drawn cylinder sheet was the first mechanical method for drawing window glass.

High in the basement of which is a motor driven winding drum.
