Abstract

Tube length production comprises repeated laser cutting of successive lengths from a tube (2) and melting the facing cut ends to form beads. Tube lengths, preferably of glass, are produced by: (a) separating tubes (2) in a supply station for individual transfer to a processing station; (b) holding the tube so it can be rotate during cutting by a laser (6) and can be moved axially for cutting of successive lengths; (c) moving each cut length axially away from the tube and simultaneously or subsequently melting the facing cut ends to form beads; (d) transferring the tube length onto a transporter having low thermal conductivity holders to avoid mechanical stress production on cooling; and (e) advancing the tube axially for cutting the next tube length. An Independent claim is also included for apparatus for carrying out the above process.
