A process and device for working a portion of an extruded profiled string over an object, in particular a glass object.

摘要

In a process for fashioning a portion of a profiled bead (2), which has been extruded onto an object, in particular a pane (1), fastened in a treatment station (E), in which process an initially shapeless accumulation of material (4) is produced in the portion in question, which accumulation of material is given a final shape corresponding to the uniform cross section, of the profiled bead (2) by means of a moving tool (5), any excess material being expelled in order to be removed, the mass of material (4) is produced by the superposition of two portions of the extruded strip, the second portion being deposited after the die (D) has been moved and repositioned. Advantageously, the tool (5) is, according to the invention, automatically aligned on the profiled bead (2), immediately after the accumulated material (4) has been extruded and after the extrusion die (D) has continued its travel, without moving the object, and is brought into contact with this bead. Also described is a device especially suitable for implementing this process.
