Abstract
A device for welding the ends of a tubular container made from plastic, in particular tubes has a holding device which holds the container in a stationary fashion with its open end facing in an upward direction and including means for warming a ring shaped peripheral region of the container proximate the opening to facilitate subsequent welding along an elongated seam travelling transverse to the longitudinal extension of the container. A mounting holds a plurality of diode lasers in an approximately circular manner such that their radiation is incident on the inner or outer wall of the container, either directly or via a deflection optics.

A device for preparing an end of a plastic tubular container or tube for welding closed an opening at an end thereof, the device comprising:
- a support device for holding the container in a stationary fashion, with the container opening facing in an upward direction;
- a plurality of diode lasers for warming a ring shaped peripheral region of the container proximate the opening to facilitate subsequent welding along an elongated seam transverse to a longitudinal extension of the container;
- and
- a support means for holding the diode lasers in an approximately circular array such that their radiation is incident on at least one of an inner and an outer wall of the container.
