Abstract
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.
Claims20
A device for welding plastic tubes comprising:
- a first tube holder having a first tube holding area and a second tube holding area parallel to the first tube holding area;
- and
- a second tube holder having a third tube holding area and a fourth tube holding area parallel to the third tube holding area, wherein the third tube holding area is alignable with the first tube holding area and wherein the fourth tube holding area is alignable with the second tube holding area;
- wherein a first tube may be placed in the first tube holding area and the third tube holding area and a second tube may be placed in the second tube holding area and the fourth tube holding area, the first tube holder having a first tube clamp and a second tube clamp, the second tube holder having a third tube clamp and a fourth tube clamp whereby a fluid free area is created in each of the first tube and the second tube,
- wherein each of the tube clamps in each of the first tube holder and the second tube holder comprises an upper jaw and a lower jaw for pressing against the respective tube between the jaws, the jaws in the tube clamps of each of the first tube holder and second tube holder having smooth tube contacting walls at a tube clamping portion, and each of the smooth tube contacting walls being of a smooth continuous curved configuration, and
- wherein the smooth tube contacting walls facilitate fluid stripping from either or both sides of the first tube and the second tube.
