Abstract

1. Portative tubing of round cross section manufactured from a continuously helically wound web material having high restoring forces after elastic deformation such as paper, paperboard or the like, the wall or wall thickness of which tubing is defined essentially by at least one layer of flutes lying parallelly to each other and being aligned with their main extension in the longitudinal direction of the web and of the helices, as well as inner and outer covering layers for the flutes, neighbouring marginal areas of the web being connected to the covering layers in the area of the crests and hollows of the flutes, characterized in, that at least one of the covering layer forms, by way of a side strip (21, 22), an integral component of the undulated web material (23) of neighbouring winding sections, and that neighbouring marginal areas of the undulated web material overlap each other and are connected with each other.
