The invention relates to a method for producing glass tubes with a cross section of a noncircular form by reshaping. This method includes at least providing a glass tube, heating the glass tube, providing at least one reshaping tool, which has a forming body with a forming area for reshaping the heated glass tube, the forming body including at least one open-porous material, setting a gas pressure in the interior of the reshaping tool lower than 90 kPa, so that a negative pressure is produced on the forming area, and reshaping the heated glass tube by applying a compressive force perpendicularly to the longitudinal axis of the glass tube, the compressive force being generated by the reshaping tool and being applied to the outer surface of the glass tube, and the outer surface of the glass tube being fixed by the negative pressure.

A method of reforming a glass sleeve and a shaping tool is disclosed. The method for reforming a glass sleeve may be carried out by providing a tube made of glass. The tube may have a longitudinal axis and an inner curved surface enclosing a space. The tube may be heated to a temperature within the soften range of the glass. A shaping tool may be introduced. The shaping tool may have at least two opposing fingers into the enclosed space. The at least two opposing fingers may extend generally radially. The at least two opposing fingers may be moved against the inner curved surface along a radial axis to reform the tube to form the first portion.

The present disclosure provides an apparatus and method for modifying the shape of a hollow structure. The method may comprise steps of providing a hollow structure having a cross-section with first and second diameters defining a first aspect ratio; heating at least a part of the hollow structure to at least its glass transition temperature, forming a malleable hollow structure; maintaining a positive pressure inside the malleable hollow structure to form a pressurized hollow structure; and pressing against a first side and an opposed second side of a heated part of the pressurized hollow structure, forming a hollow tabular structure having first and second opposed generally flat faces and a second aspect ratio greater than the first aspect ratio.
