Abstract
ABSTRACT OF THE DISCLOSURE
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°, 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° so that the seam is made, without discontinuity, along the entire border of the article, another device, similar to the previous one, is used.

Description
8~
The pres-ent invention realtes to apparatus used to apply pieces of fa~xic to manufactured axticles, and especlall~ to pant~ hose.
It is kno~n from other patents of the present applicant that a rotating fixture can be used to appl~ a piece of fabric to panty hose. The fixture includes several stations. ln the first station the manufactured article is positioned in such a ~ay that lts seamless border can be stretched on a suita~le annular support. A second station is used or pne~matically overturning the article into the interior of the said supportO ~ third station is used to transf~r the piece of fabric under the stretched border of the article.
~ fourth station is used for clipping both the fabric and the stretched border of the article, the cut being done right above the seam. A ifth station is used to se~ the fabric to the articleO
At the si-te of ~he third station a device is installed for cutting the fabric from a continuous ribbon. This device is continuously operating.
Another device which is also continuously opexating is that which brings the fabric to the stand supporting the manufactured article. These devices are al~ays operating in the sense that they operate wheth0r or not the article is present on its s-tandO Consequently, the ~abric is wasted when the article is not available on its stand. The present invention aims at correcting this situation. In additlon to doing so it also provides a means of controlling the rotation of the fabric as well as the manufactured article, at the site of the clipping station, by an angle greater than 360, in order to have, as a more suitable place for se~ing, the front side of the fabric3 at the site of the follo~ing se~ing station, in a position different from the position of arrival at the clipping station, If the fabxic has a square shape, the rotation should preferably be 360 ~ 180o If the fabric has a polygonal shape with n sides, 1~9'71~
the rotation should preEerably be 360 ~ 360. Moreover, the invention aims at controlling also the rotation of the article and of the fabric, at the site of the sewing station, by an angle greater than 360, in order that a continuous seam along the circular border of the article is made.
These results are achieved, according to the invention, by providing a control device for a carrousel-type machine for applying a gusset to a pantyhose article, said carrousel-type machine having a rotatable suppcrt adapted for having a pantyhose article applied thereto, said control device comprising: means for verifying the presence or absence of the pantyhose article on the support; means for reading a cylindrical, uniform graduation integral with the support; and means responsive to said verifying means and said reading means for transferring the gusset to said support only when said verifying means indicates the presence of the panty hose article on said support and to insure that said support rotates through at least 360 so that the carousel-type machine is operable only when a gusset is in place and to insure the complete sewing along the entire perimeter of the gusset.
Several advanta~es result from the present invention. They are mainly the following: the ribbon from which the piece of fabric is cut is now fully utilized, without any waste; the seam of the fabric has no defects and is continuous around the circular border of the manufactured article; the seam of the fabric is now exactly the same for all the manufactured articles.
Reference is now made to the accompanying drawings, in wnicn :
