Abstract
A method of making a peelable tube assembly (76,80,84,88) having a plurality of adjacent tube portions (62) joined by intermittent breakable webs (72) of plastic allowing the individual portions (62) to be peeled from the tube assembly, including providing a plurality of plastic tube portions (62) each having a tube wall (66) defining a flow passage (70). The tube portions (62) are aligned adjacent to one another in a die assembly (12) having compression channels (30). Narrow confined flow chambers (32) are defined between adjacent portions (62) of the tube walls (66), and between the ends of the tube walls (66). The tube portions (62) are radially compressed without occluding the flow passage (70). Small compressed portions of the tube walls (66) proximate the flow chambers (32) are heated and plasticized. The plasticized tube walls portions (66) are flowed into the flow chambers (32) between the adjacent tube portions (62) to fuse the adjacent tube portions ( 62) together with intermittent webs (72) joining the tubular portions (62) until the webs (72) are broken when peeling a tubular portion (62) from the tube assembly (76,80,84,88).
