<p>In apparatus for applying pieces of fabric to manufactured articles of tubular shape, and especially to panty hose, a photoelectric cell is employed to reveal the presence of the manufactured article on its stand and to bring the fabric close to the article in the corresponding station only if the article is present on its stand. In order to have both the fabric and the article rotated, in the corresponding clipping station, by an angle greater than 360.degree., so that one border of the fabric reaches, in the following sewing station, a position different from the position of arrival at the said clipping station, a device is used that controls the rotation of the stand supporting the manufactured article. Such a device can be, for instance, a reader provided with a programmed memory so that the readout from a graduated cylindrical scale is stored in the memory and, as soon as the rotation is completed by the amount stored in the memory, the said device arrests the rotation of the stand. In order to have both the fabric and the manufactured article rotated, at the sewing station, by an angle greater than 360.degree. so that the seam is made, without discontinuity, along the entire border of the article, another device, similar to the previous one, is used.</p> |
