ABSTRACT:
Apparatus for the opening or stretching apart of one end (10) of a tubular article (1), comprising a body (T) of substantially tubular shape, with an entry section (I) of the end (10) of the articles (1) to be treated and communicating with air suction means, in which downstream of the section (I) a converging-diverging conduit (2) is provided downstream of which, at a predetermined distance, there is a pin member (3) on which the end (10) of the article is to be fitted by virtue of the suction and of the expansion or opening caused by its transit along the region (20) downstream of the conduit (2). The body (T) is made up of two portions separable with respect to a central longitudinal plane (x--x) at least in correspondence of the above mentioned pin member (3) to allow the removal of the article (1) with its end (10) in streteched condition. (FIG. 1).
