Abstract

A continuously operating machine for forming tubular plastics containers or vessels comprises, in succession along the path of a plastics sheet as it is drawn from a feed roll, the following: an appts. comprising V-shaped guides for forming the flat sheet to a V, a mandrel with an external ring around it, and a heater, so that the sheet is folded from a V into a tube and sealed, and a cutter which cuts the hollow cylinder to length; a limit switch actuates the cutter when the hollow cylinder reaches the desired position. There is pref. also an extruder for applying liq. resin to the edge of the strip. Used for all kinds of tubular prods., for example toothpaste tubes and the like.
