Title: Welding jaw

Abstract: A welding jaw for thermoplastics material comprises a cooled carrier with two parallel heating elements on one surface. At least part of the surface of the carrier is so spaced from the surfaces of the elements that on welding, material flows from under the element to be cooled and hardened on contacting the surface part. Thus allows rapid firm welding and is particularly useful in transverse welding of liquid filled tubes.
