Abstract: A device for drawing glass ribbons is provided. The device includes a drawing tank and a nozzle in the drawing tank. The drawing tank holds a glass melt. The nozzle has a nozzle slot through which the glass melt emerges downward. The nozzle slot has two ends, a length, and a width, the length being greater than the width. The nozzle slot is curved downward toward the two ends in a drawing direction so that the two ends are lower than a center of the nozzle slot. The width changes from the center towards the two ends.

Abstract: In a method for producing a pipe made of a fiber-reinforced thermoplastic material, two workpieces of the material are provided. The workpieces are introduced into a tool having a core and two part molds surrounding the core. The workpieces are heated and shaped between the core and the part molds to give a structural part of the pipe. The core is removed from the structural parts, the structural parts being held on the part molds, and joining regions of the structural parts are oriented towards one another. The structural parts are joined to one another in the joining regions to form the pipe. The pipe is released from the part molds, wherein the part molds are moved away from one another after shaping in order to remove the core, and are then moved back together in order to orient the structural parts towards one another.
