Abstract:
1. A device for welding plastic tubes comprising: a first tube holder having first and second parallel tube holding areas; a second tube holder having first and second parallel tube holding areas which are alignable with said tube holding areas of said first tube holder whereby a first tube may be placed in the first tube holding areas and a second tube may be placed in the second tube holding areas, said first tube holder having a first tube clamp and a second tube clamp, said 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 said tube clamps in each of said first tube holder and said second tube holder comprises an upper jaw and a lower jaw for pressing against the respective tube between said jaws, said jaws in said tube clamps of each of said first tube holder and second tube holder having smooth tube contacting walls at their respective tube clamping portions, and each of said smooth tube contacting walls being of a smooth continuous curved configuration facilitating fluid stripping from either or both sides of the first tube and the second tube, wherein the first tube is slidably coupled to the first tube holder and the second tube is slidably coupled to the second tube holder, wherein a length of fluid free area is maintained in each of the first tube and the second tube, and each of the first tube and the second tube being slidable through a side of at least one of the first tube holder and the second tube holder with least resistance, and a cutting/welding station to cut through the first and second tubes in a first operation and for welding portions of the tubes in a second operation.
