Definitions

  • This invention concerns a procedure for forming a pantyhose product with continuous processing motion on knitting machines with two needle beds.
  • the invention also concerns pantyhose products made according to said procedure and also knitting machines with two needle beds which employ said procedure and are suitable for making said products.
  • Said procedures envisage the formation of two knitted tubes, one within the other, on the two circular needle beds.
  • the part relating to the legs is obtained with independent tubular products.
  • tubular products are connected together along at least one lengthwise line and are separated along a lengthwise line located intermediately in relation to said line of connection.
  • the inner tube is then withdrawn and turned inside out so as to obtain an open, symmetrical pantyhose product.
  • patent IT 916700 (US 4,011,738) in the name of Solis S.r.l. describes a procedure for knitting machines with two cylinders which envisages the formation of the panty portion with alternate motion of the cylinders. Said procedure enables 360° knitted courses to be formed substantially with the passage of the yarn from one needle bed to the other at every inversion of the motion of the cylinders.
  • the two leg portions are formed, one within the other, with smooth stitches and purl stitches respectively, the processing being carried out with continuous motion of the cylinders and with an independent feed on the two needle beds.
  • This procedure also involves a poor appearance owing to the presence of a lengthwise portion without stitches which is formed with straight yarns and which corresponds to the line of the crutch of the panty portion.
  • this line of the crutch corresponds to said lengthwise edges connecting the outer knitted tube to the inner knitted tube.
  • Said lengthwise portion without stitches is produced by the yarn passing from one needle bed to the other and has a width substantially the same as the distance between the two opposed cylinders.
  • said lengthwise portion without stitches impairs the strength and stability of the panty portion of the product.
  • Patent IT 992231 (US 3,975,924), also in the name of Solis S.r.l., describes a procedure for knitting machines with two cylinders which envisages the formation of the panty portion with a continuous rotary motion of the cylinders.
  • Said procedure envisages that the yarn passes from the needles of the first cylinder to the needles of the second cylinder at a position distanced at an angle from the position at which the yarn passes from the needles of the second cylinder to the needles of the first cylinder.
  • Certificate of authorship CS 169.533 (UHLIR) visualises a procedure whereby it is necessary to employ a machine working with needles with a double spring so as to obtain the fabric as envisaged in the connecting zone.
  • said connecting zone comprises courses of stitches formed with plain and purl stitches in a varying succession and said stitches can be obtained with the same needle only if the latter has a double spring.
  • CS 169.533 provides a body portion which, given the same gauge of cylinders, is made with half the number of needles as are used in the invention we are proposing.
  • our invention visualises stitches which are all of the same kind and the connection between the two fabrics which open out and form the panty portion is made in a different way.
  • Certificate of authorship CS 195.758 offers a procedure with substantial limitations. Said procedure envisages that the needles of the lower cylinder work offset in relation to those of the upper cylinder and that therefore the panty portion, given the same gauge of cylinders, is obtained with half of the needles used in the procedure of our invention and is therefore less easy to wear.
  • Each of the two edges of fabric which are united with loops consists of stitches made with the same yarn, whereas our invention envisages that the stitches of the connecting loops are made with the yarn with which the other edge is processed, thereby ensuring greater stability.
  • the needles of the lower cylinder will therefore have to penetrate into appropriate grooves in the opposite cylinder and we cannot see how they can still take the yarn P2 in such a position.
  • Patent application IT 9522 A/80 in the name of the author of the present invention describes a procedure for knitting machines with two cylinders or with a cylinder and dial whereby it is envisaged that the panty portion is formed with continuous motion of the cylinders. This is done by forming the two tubular parts connected along a lengthwise zone, where needles of both the needle beds are actuated during the formation so as to obtain, with one or more feeds, a structure of rib stitches with continuous plain stitches and purl stitches. The produce visualises that a lengthwise separating cut is made.
  • said procedure ensures greater strength and stability in the panty part of the product but does not overcome the problem of appearance which, given the nature of the product, is the most important problem.
  • the purpose of our invention is to embody a procedure for processing the products which overcomes the aforesaid technical problems and provides a product with an excellent appearance.
  • a procedure for forming a pantyhose product with continuous processing motion on knitting machines with two needle beds and with at least two feeds, one for each needle bed, said procedure envisaging the formation of two knitted tubes, one within the other, on two needle beds, whereby the two tubular fabrics are joined together along a lengthwise connecting zone having a length which corresponds substantially to the panty portion of the product, and a lengthwise separating cut is made substantially at the centre line of said connecting zone, said procedure being characterized by the fact that, so as to form the zone connecting the two knitted tubes with at least one feed, the yarn is knitted by needles selected at substantially regular intervals on one needle bed and also by some needles selected on the opposed needle bed, wherein the needles of the first needle bed which have not been selected pass with their own hooks as the same level as the respective sinkers so as not to take the yarn, the needles selected on said opposed needle bed being aligned with needles of said first needle bed which have not been selected, said selection being performed in such
  • This invention also concerns a machine with opposed needle beds for making two concentric, tubular fabrics by means of at least two feeds of yarn, one for each needle bed, whereby for the connection of said tubes an arc of needles is employed which has a width corresponding to the connecting zone, together with the use of at least one of the two feeds of yarn, said machine being characterized by the fact that in said connecting zone the needles of the corresponding needle bed are selected in such a way that one needle in every N needles passes with its own hook at the same level as the respective sinkers so as not to take the yarn, and that also some of the needles of the opposed needle bed aligned with said needles oftheJicstJieedie bed passing at the same level as the respective sinkers so as not to take the yarn are set to work and knit the yarn with the stitch of the tubular fabric processed by said needles, of said first needle bed thereby forming a connecting bridge, said selection being performed in such a way that said needles of said opposed needle bed which are selected in our course are not selected in the
  • This invention is also embodied with a pantyhose product made with said procedure and with a machine as in the foregoing.
  • said processing procedure obtains an excellent appearance and very good strength and stability in the panty portion of the product.
  • two knitted tubes 53A and 53B are formed so as to embody a pantyhose product 50 and that each knitted tube is processed on a needle bed with at least one feed 56 of yarn 55.
  • connection between said tubes is made during processing along a tract of the lengthwise development of the two knitted tubes 53A-53B so as to form the body portion, or panty portion, 51 of the product 50, and that a separating cut 62 is also made substantially on the centre line of the connecting zone 52.
  • the parts 61 of the connecting zone 52 which are nearest to the line of the cut 62 and are like the so-called loose threads at the end of work are inside the panty portion 51 of the product 50.
  • continuous motion is used to form the panty portion 51 of the product 50 and it is envisaged that needles 54 and 154 of both the needle beds A and B are actuated at the same time in the zone 52 of connection of the two knitted tubes 53A-53B.
  • needles 54 at regular intervals are actuated on one needle bed A and some needles 154 of the opposite needle bed B too are actuated at the same time so as to connect the two knitted tubes 53A-53B together.
  • Such a procedure obtains stitches which are all of the same type, and the union of the two fabrics constituting the two knitted tubes 53A-53B which open out and form the panty is obtained with connecting loops between two edges of fabric overlaid on each other.
  • Said solution not only enables a more wearable body portion (panty) to be obtained but also enables a long-term stable union to be obtained between the two edges.
  • connection is obtained by knitting the yarn 55 on both the needle beds A and B.
  • needles 154 which are selected on said opposed needle bed have to be offset in relation to the needles 154 actuated for the previous course and for the next course made with the same feed 56 of yarn 55.
  • Figs. 1, 2 and 3 show a preferential embodiment of the procedure according to the invention.
  • the zone 52 connecting the knitted tubes 53A-53B is embodied in this instance within a sector corresponding substantially to thirty-two positions of needles 54-154 and a lengthwise separating cut is performed so as to correspond with position 16.
  • the needles 54 on the needle bed A are actuated with a selection of one yes, the next not, and so on, whereas only given needles 154 are actuated on the opposed needle bed B.
  • Figs. 1, 2 and 3 show the needles 154 respectively selected in the connecting zone 52 after N successive revolutions of the cylinders.
  • needles 54 are selected on needle bed A, but needles 154 corresponding to positions 2, 8, 14 and 18 are selected on the opposite needle bed B.
  • Positions such as 10, 16, 22 have to be separated from each other by a number of needles proportioned to the distance between the plane of formation of stitches of the sinkers of the upper cylinder and the plane of formation of stitches of the lower cylinder, in practice it can be seen that a position such as 10, 16, 22 must exist at least every three needles.
  • Figs. 4, 5 and 6 respectively show the connections made between the two knitted tubes 53A-53B after actuation of needles 54-154 comprised in positions 1 to 32 according to the selection shown in Figs. 1, 2 and 3.
  • the machine with opposed needle beds for making two concentric tubular fabrics 57A-57B by means of at least two fees 56 of yarn, one for each needle bed A-B is characterized by the fact that the selection of needles on the second needle bed B is changed in the courses thereafter by being moved by x needles, whereby x equals two advantageously.
  • Said actuation of needles 54-154 at the zone 52 of connection of the two knitted tubes 53A-53B entails the embodiment of two fabrics 57A-57B with smooth stitches, which are respectively plain and purl.
  • Said fabrics 57A-57B comprise connecting bridges 59, each of which also bears a specific reference number in the figures, namely 110, 116, 122, 102, 108, 114, 118, 112, 120, 126 and 132, depending on the position where they have been embodied.
  • each of said connecting bridges 59 consists of a loop 60 of one of the two fabrics 57A, said loop being extended and knitted into the other fabric 57B, as shown in Figs. 7 for instance.
  • FIGs. 7 show a front enlargement of some connecting bridges 59 in two fabrics 57A-57B which have by now been opened and turned inside out as in the diagrammatic figures 8, 9 and 10.
  • Fig. 7a shows the case wherein the connecting bridges 59 are made in one revolution but not in the next revolution, and so on, thus ensuring proper fastening of the loops.
  • Fig. 7b shows the example of connecting bridges 59 located in each line; in this case the bridges have to be offset by one wale so as to have a proper, stable anchorage of the loops.
  • Fig. 7c instead shows the case of inverted bridges which start now from the fabric 57A and are knitted into 57B and then start now from 57B and are knitted into 57A.
  • Fig. 11 gives a diagrammatical front view of the panty portion 51 of a product 50 made with the procedure of the invention; in said product the fabrics 57A-57B of the panty portion 51 are fully open and stretched out. The exceptionally good-looking appearance of the connecting zone like a slide fastener can be seen clearly.
  • edges of saidd zone can be distinct or graduated and said zone can also comprise one or more layers of connecting bridges 59.
  • Said figures 8, 9 and 10 show cross sections of the panty portion 51 of the product turned inside out and opened; said sections correspond respectively to courses of stitches of the product which are made in the connecting zone with the selection of needles as shown in Figs. 1, 2 and 3.
  • said criteria of actuation of the needles entail the formation of a connecting zone 52 having an increased thickness and consistency and the further improvement of the appearance of the part connecting the two knitted tubes 57A-57B that constitute the product 50.
  • the connecting courses comprising the connecting bridges 59 are spaced apart from each other, that is to say, they are not consecutive courses.
  • connecting courses comprising the connecting bridges 59 are separated from each other by one or more connecting courses forming one single ribbed fabric in the connecting zone 52, said fabric being made by cooperation between the needles of both needle beds A-B in the connecting zone 52.
  • a connecting tract formed of one single ribbed fabric obtained by cooperation between the needles of both the needle beds A-B in the connecting zone 52 is comprised in the connecting zone 52 at every two connecting tracts obtained with a number of courses comprising connecting bridges 59, whether separated or not by courses of rib stitches.
