Abstract

1291839 Making collapsible tubes; tube-expanders JOHN DALE Ltd 3 Dec 1969 [18 July 1969] 36371/69 Headings B3A and B3J An expanding mandrel for forming collapsible toothpaste &c. tubes comprises separate segments 11 hinged at one end, means 45 for turning the segments about the hinges so that the outer generally cylindrical surfaces of the mandrel assumes tapered form, means 47 for operating the turning means 45 and a plastics or rubber sleeve 50 surrounding the segments. The segments 11 are retained on a rod 30 by spring rings 26 and a flanged plate 35, about which they are turned by the cone 45 as they are drawn endwise by the rod 30. The rod is operated by cam or fluid pressure and has a collar 31 engaged in a recess 16 in the segments. The arc of the outer surface of the segments at the expanding end is such that this end is substantially circular when expanded. The cone 45 may be of phosphor bronze or hardened steel and the segments may be hardened. In a modification, Fig. 4 (not shown), a frusto-conical end (73) of the rod effects a small expansion of the left-hand end of the segments before they move with the rod for expansion of the opposite end.
