Definitions

  • the invention concerns an improved procedure by means of which a pantyhose product or the equivalent can be made directly on a machine by using circular knitting machines which produce stockings or socks, for instance, and which are of a two-cylinder type or have a cylinder and a dial with radial needles but in any event have two needle beds of cooperating needles.
  • the invention also concerns a machine fitted to carry out the method of the invention and concerns also a product obtained with the method in question.
  • Patent US 3,975,924 (FURIA) is known in which, among other things, there are shown two different and not comparable solutions; these solutions are shown in Figs. 1, 5 and 13 and in Figs. 8, 9, 10 and 12 respectively.
  • the first solution of FURIA envisages working in such a way that the needles (Fig. 1) of the cylinder 11, which make the plain stitching 21, are in fact inactive in the tract between A and B. Only the needles of the cylinder 13 (thus only one needle bed) work in this tract, after transfer of the yarn from 11 to 13, as shown clearly in Fig. 13. Thus in the tract A1­B1 there is double processing; by cutting along T the following disadvantages are produced:- an aesthetically ugly tract 151 positioned in two columns at the side of the centre of the panty portion: a very unstable tract 15, the stitches A1 and Bl all being aligned in the same column.
  • the second solution envisages that the yarn of one stitch passes at A into another stitch (on one needle bed) and is processed therein until B, where it returns to the original stitch (original needle bed).
  • our invention fulfils its purpose of ensuring greater stability in the connections between the two parts of the product along the line of the crutch, of permitting simpler and also faster processing and of obtaining a satisfactory aesthetic appearance.
  • the invention is obtained with a procedure to form a pantyhose product or the like on a double-cylinder or cylinder-and-dial knitting machine by processing with continuous rotating motion, whereby two tubular products of the panty portion are formed at one and the same time on respective needle beds and with different feeds or descents of yarn, and whereby the panty portion is formed first with parts of tubular material with a lengthwise connecting zone which is subsequently cut in a lengthwise direction, such procedure being characterised by the fact that in the single-layer connecting zone needles of the two needle beds are actuated simultaneously to form with one feed or a plurality of feeds or even with all the feeds such that each yarn is knitted in the connecting zone by needles of both the upper and lower needle beds to form a rib stitch structure with plain stitches and purl stitches next to each other, the needles of one needle bed knitting in the free space left by needles of the opposite needle bed.
  • the structure of the rib stitching can be of a 1:1 type, namely with one plain stitch and then one purl stitch.
  • the connecting zone can be formed with two bands, namely zones of rib stitching separated by a tract which has yarns that are not knitted and in which the cut is made; each band is formed with some rows of stitches which are alternately plain and purl.
  • the connecting zone can be made with a number of courses greaterthan (two time greater, at the most) that of the neighbouring textures.
  • the invention also concerns a machine to perform the above procedure, the machine being of a type in which two cylinders or a cylinder and dial cooperate with cam means that actuate the needles of one cylinder or of one of the cylinder or dial in correspondence with certain feeds and actuate the needles of the other needle bed in correspondence with other feeds, so as to form two products, one inside the other, means being provided to drive the needles of a connecting zone so as to connect the two products in a lengthwise direction and also to make a lengthwise cut in the zone in order to form the line of the crutch, the machine being characterised by including an arc of corresponding needles in each of the two needle beds which are actuated to knit together to form such connecting zone and being capable of being driven at least at one feed so as to take the yarn alternately with needles of one or the other needle bed in order to form rows of rib stitching, means being provided to actuate the needles of one needle bed such that they knit in the free space left by the needles of the opposite needle bed.
  • a further object of the invention is a pantyhose product or the like obtained with the above procedure and with the machine defined hereinbefore, characterised by the fact that the one single-layer connection zone formed with the needles of both beds is connected tightly to the stitches of the tubular portions of the pantyhose product, whereby the crossed yarns of the wales of stitches forming the connection zone are overlaid on the back of such connection zone on the outside of the pantyhose product.
  • Figs. 9 to 12 inclusive show a lay-out wherein are visualized a needle bed 11 in a cylinder and a needle bed of radial needle hooks 13 in a dial combined with the cylinder.
  • A1, A2, A3 and A4 indicate four positions of yarn feed with thread guides G1, G2, G3 and G4.
  • the needles 11 take the yarn, they form plain stitches, whereas when the needles 13 take the yarn, they form purl stitches.
  • the needles 13 take the yarn in correspondence with the feeds A2 and A4
  • the needles 11 take the yarn in correspondence with the feeds A1 and A3; the two tubular elements, which have the reference numbers 15 and 17 respectively, are thus formed progressively at one and the same time.
  • the single-layer connecting zone Cc is made by processing simultaneously with needles 11 and with needles 13 structures of fabric with rib stitching, whereby the needles 11 and needles 13 are actuated at the same time in correspondence with one feed or several feeds or even with all the feeds A1, A2, A3 and A4.
  • a lay-out of this kind is given in Figs. 9-10 and 11-12, which show two moments in the formation of the connecting zones of fabric Cc respectively in front of the feed A1 and feed A2 of a cylinder-and-dial unit with needles.
  • Figs. 9 and 10 show the momentary condition in which the needles passing before the feed A1 are pre-set to form the zone Cc; therefore, at that moment not all the needles 11 are raised, nor are .all the needles 13 kept inside; but rather in front of the feed A1 (which usually serves for the formation of the product with the needles 11), out of all the needles 11, only those indicated with 11A (two pairs in the figure) are raised, while the needles marked 11 B and also the two middle needles 11 C are kept low; furthermore, in that situation the needles 13 of the dial indicated wiht 13A, which correspond with the unraised needles 11B, are also withdrawn; before the feeds A2 and A4 only the needles 13 come out (to form the fabric 15), while in front of the feed A3 only the needles 11 come out (to form the fabric 17).
  • the needles pre-set for formation of the zone Cc namely the needles 11A, 11B, 11C and 13A, which are once more selected, as already said with regard to Figs. 9 and 10, for the feed A1 in such a way as to form the connecting zone Cc of fabric.
  • Figs. 7 and 8 show the lay-out and method of working to obtain the invention in the case of a machine with two opposed cylinders.
  • the references A11, A12, A13 and A14 indicate the four feeds exemplified (but the lay-out may have any other number of feeds greater than one), whereas G11, G12, G13 and G14 are the respective thread guides.
  • the needles 31 of the lower cylinder work with the feeds A11 and A13 to form the fabric 17, whereas the needles 33 of the upper cylinder work with the feeds A12 and A14 to form the fabric 15.
  • the needles of the two cylinders are driven in front of all the feeds so as to make the lower needles 31A take the yarn; the needles 31 B and also the needle or needles 31C being kept low, and to make the upper needles 33A (corresponding with the needles 31B) take the yarn, the needles 338 and also the needle or needles 33C being prevented from protruding and being kept within the upper cylinder.
  • the zone Cc passes before the feed A11, while in Fig. 8 it passes before the feed A12; this function is also repeated in front of the other feeds A13 and A14.
  • butts can be envisaged which have a special height or particular levels on the needles or needle jacks in the channels of the said needles, or else other dispositions may be made for the purpose which are well known to experts in this field. It seems to be enough to process the connecting zone Cc with the two feeds A1 and A3 (or A11 and A13) alone.
  • the cut indicated with the arrows T is made in this central zone F; this cut can be performed in any suitable way, for instance with heat applied by a resistance that melts the yarn, or with a cutter device with blades actuated in a suitable manner, or with elements sliding in the needle seatings and equipped with a blade or other cutting edge caused to operate when such element is raised, the solution being analogous to that of the needles.
  • the cut can be made directly on the machine, and the product therefore reaches the situation shown in Fig. 4 with one of the tubular products 17-15 inserted in the other, for in that condition they are seen as they are formed by the two needle beds 11 and 13.
  • the product is then spread apart, with the fabric 15 bent outwards from the fabric 17 and turned over, as shown in Fig. 5, so as to reach the situation of Fig. 6, in which the connecting zones C, like the so-called "runs" at the end of working, are inside the product.
  • the connecting zones C like the so-called "runs" at the end of working, are inside the product.
  • the zones C there is a stable union of the product along the line of the crutch, as is shown in Fig. 6 where it can be seen clearly that the parts C form the connection between the two fabrics of the sides of the body of the product.
  • the fabric in the zones C consists, as said earlier, of rib stitching and of yarns belonging alternately to one or the other of the tubular fabrics 15 and 17.
  • connections can be made with all the feeds or with a reduced number of feeds. If we consider the case of four feeds Al-A2-A3-A4, the use of all these feeds to make the connection enables the crosswise stresses to be reduced, as the connecting zone will thus have a number of courses twice as great as the number of courses in the neighbouring fabrics; a connection made with only two feeds is performed with the same number of courses as that of the neighbouring fabrics and permits a given mechanical simplification.
