DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a process and device for closing the initial end of a tubular article, for example the toe of a sock or other, during formation on a circular knitting machine.
BACKGROUND ART
Processes and devices for obtaining directly on the circula knitting machine a cloesd toe in a sock or the like are disclosed for example in Italian Patent Application n. 9465A/90, filed Aug. 10, 1990 or in Italian Patent Application n. FI 91 A 227, filed Sep. 13, 1991. These known methods and devices did not give satifactory results.
Attempts have been made to close the toe of the stocking directly on the circular knitting machine.
Italian patents n. 676.845 and 685.974 to Giuliano Ugolini disclose the closing of the toe,. Upon completion of the knitted tubular article, by means of,a device which replaces the normal dial plate. It is therefore impossible to knit a double hem, which requires use of the dial hooks.
Italian patent n. 1.205.775 to Schiavello also discloses the closing of the toe upon completion of the tubular article. The transfer of the loops upon closing of the toe should be provided by mechanical members whose functionality is not convincing.
All these prior art devices, moreover, have the drawback of a relatively coarse end (unthread portion) protruding from the article at the toe region.
Italian patent application n. 9465 A/90, filed Aug. 10, 1990 in the name of Conti Florentia and Italian patent application n. FI 91 A 27 filed Sep. 13, 1991 in the name of Bazzanti, disclose an apparatus which allow to begin the working of the article Starting from a closed toe on the same machine on which the article is then completed. These machines have several functional complications which are eliminated by the present invention.
OBJECTS OF THE INVENTION
The object of the invention is to provide a device which ensures ample free space inside the cylinder and correctly transfers the fabric--initially knitted on one arc of needles--to the needles of the complementary arc. These and other objects and advantages will be made clear by the following text.
SUMMARY OF THE INVENTION
The process is designed to close the initial end of a knitted article--such as a sock or other--directly on the circular knitting or stocking machine which can form a portion of fabric in the form of a pocket with narrowing sections and widening sections along an arc of needles of approximately 180.degree. comprising the transfer of the formed fabric to the area opposite said arc of needles which have formed the fabric of the pocket. According to the invention, the transfer is carried out in two phases: in a first phase, the edge with the initial course of said fabric pocket is drawn toward said opposite area; and in a second phase, with the penetration of pin-shaped appendages into the fabric, said edge is moved further up to the needles of the arc complementary to that whose needles have formed the pocket; the needles of said complementary arc are raised and inserted into the fabric of the pocket, engaging it with the fabric which is to be formed by said needles.
The device according to the invention is applicable--for closing the initial end of a knitted article such as a sock or other--directly to a circular knitting or stocking machine which can form a portion of fabric in the form of a pocket with narrowing sections and widening sections along an arc of needles of approximately 180.degree., with a reciprocating motion of the cylinder or with a continuous motion and cutting of the threads. The device carries out the transfer of the initial partial edge formed by the arc of working needles for the pocket to the needles of the opposite arc, to which said edge is transferred. According to the invention, the device comprises, in combination, mechanism--adjacent to the internal wall of the needle cylinder--to move said push rod in an axial plane of symmetry to engage by means of the pick-up hook in an intermediate position the initial courses of the partial fabric released by the needles and to bring them pr
