Abrégé

A device for welding plastic tubes includes a pair of tube holders each of which has a tube clamp which includes an upper jaw and a lower jaw. The jaws in both of the tube clamps of both tube holders have smooth tube contacting walls to permit the tubing to slip through either side when the tube holders and tubes are being moved from a loading station to a stripping station to increase the length of fluid free area in the clamped tubes. A cutting/welding station provides for cutting the tubes and welding them together.

Abrégé

A device for welding plastic tubes includes a laterally movable tube holder having tube holding areas and a laterally fixed tube holder having tube holding areas. Each tube holder includes clamping structure for clamping each tube placed in the respective tube holder areas and for creating a fluid free area. A spring mechanism urges the laterally movable tube holder toward the laterally fixed tube holder to maintain the clamp faces flush against each other. A clamp locking mechanism is provided to supplement the action of the spring mechanism by maintaining the clamp faces flush against each other during the loading of the tubes.

Abrégé

Plastic tubes are welded by first placing the plastic tubes across aligned tube slots in a pair of side by side tube holders. The tubes are clamped to create a fluid free area. The clamps in one of the tube holders are shifted laterally away from the other tube holders to increase the fluid free area of each tube. A cold cutting device cuts through the clamped tubes to create four stub ends. The four stub ends are heated/melted. The stub ends are realigned so that the one stub end in one holder is aligned with the other stub end of the other tube holder and the realigned stub ends are pressed into contact with each other to create a weld seam.
