  • Publication number: 20020124781
    Abstract: System for sensing the orientation of a product, especially of a textile article such as a stocking, a sock and the like having a first and a second differently shaped ends, for detecting which of the two ends is forward along a preset work and/or transfer path. The system includes the following operating steps:—subjecting each product to a first reading and a second reading by optical detection means disposed along at least a first front of reading transverse with respect to said work and/or transfer path, said readings being carried out on the foremost portion of the product along a direction of relative advancement thereof with respect to said optical means;—comparing the result of said first and second readings for checking any coincidence between the two readings;—emitting a signal relevant to the identification of either the first or second end in correspondence, respectively, of the coincidence or non-coincidence of the two readings.

  • Patent number: 6155466
    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).
