Definitions

  • the present invention relates to a needle for transferring stitches from the needle itself to adjacent needles for knitting machines for hosiery or the like.
  • needles In the field of knitting machines for hosiery, needles are known which are provided in order to allow to transfer a stitch or loop of knitting from one needle to an adjacent needle arranged in the same bed.
  • a needle of this kind allows to transfer the stitch exclusively onto the needle that is arranged on one side of the needle that has to release the stitch.
  • WO2007/057041 by the same Applicant, assumed included herein as reference, illustrates a needle that is capable of transferring, according to the requirements, the stitch onto the needle that is arranged on one side or to the needle that is arranged on the opposite side of the needle that has to release the stitch.
  • the needle according to WO2007/057041 comprises: a shank, a head arranged at a longitudinal or upper end of the shank, and a latch that is hinged to the shank proximate to the head, about a pivoting axis that is substantially perpendicular to the longitudinal axis of the shank and rotatable about said pivoting axis in order to open or close the head.
  • the needle comprises at least one elastically flexible lamina, which is associated with the shank and defines, on the two opposite sides of the shank, below the latch, two receptacles, one for each side of the shank. It is possible to insert in each of these receptacles the head of an adjacent needle in order to transfer the loop of knitting, carried by the shank and arranged at the receptacles, from said needle to the adjacent needle.

  • the laminas 6a, 6b are obtained by means of a single portion 23 formed by blanking, shown in Figure 18 , and folded along the line 24.
  • the blanked portion 23 is further bent to provide the first segment 13a, 13b and the third segment 15a, 15b.
  • the laminas 6a, 6b are obtained by means of a single portion 25 formed by blanking, shown in Figure 20 , and folded along the line 26.
  • the blanked portion 25 is further bent to provide the first segment 13a, 13b and the third segment 15a, 15b.
  • the portion of the shank 2 that lies between the portion 8a, 8b of the lamina 6a, 6b above the blending region 10 and the head 3 has a front cutout that reduces the front space occupation of the shank 2 so as to avoid its interference with the rear protrusion 18a, 18b of the portion 8a, 8b of the lamina 6a, 6b of the adjacent needle during the transfer of the loop of knitting 9.
  • the needles that are adjacent to the needle 1, which must release the stitch or loop of knitting 9, have been designated by the reference numerals 1a, 1b, but can be provided, as shown, like the needle 1 described up to now.
  • the needle 1, arranged between the needles 1b, 1a is the needle that carries the loop of knitting 9 and must release it to the adjacent needle 1b, while the other needle 1a, arranged on the opposite side with respect to the needle 1b relative to the needle 1, is not affected by the transfer of the loop of knitting 9.
  • the needle 1 is referenced hereinafter also as “releasing needle”
  • the needle 1b is also referenced as “receiving needle”
  • the needle 1a is also referenced as "inactive needle”.
  • the needle 1 After forming the loop of knitting 9 and after knocking over the loop of knitting formed previously, is raised, by means of the needle actuation cams with which its heel 5 engages, so as to protrude for a segment above the knitting formation plane 21, which, as is known, is formed by the sinkers, not shown for the sake of simplicity in Figures 5 to 9 , which retain the loops of knitting 9 that have just been formed.
  • the extent of the lifting of the needle 1, which must release the loop of knitting 9, is such as to bring the portion 8a, 8b of the laminas 6a, 6b at the knitting formation plane 21 and extract the portion 8a, 8b completely from the region that is occupied by the so-called "strips" that delimit laterally the seats, constituted by axial slots of the lateral surface of the needle cylinder 40, in which the needles slide.
  • the laminas 6a, 6b first pressed against the shank 2 of the releasing needle 1 by the presence of the strips, move away by elastic reaction from the shank 2 with their portion 8a, 8b, which thus passes into the active position.
  • the shank 2 of the needle 1 slides within the loop of knitting 9, which, being crossed first by the blending region 10 and then by the portion 8a, 8b of the laminas 6a, 6b up to the resting shoulder 17a, 17b, is widened progressively in a manner in which it is suitable to be crossed at least by the receiving needle 1b.
  • the presence of the blended region 10 ensures a gradual expansion of the loop of knitting 9, avoiding excessive stresses both of the loop and of the laminas 6a, 6b.
  • the receiving needle 1b onto which the loop of knitting 9 is to be transferred, is moved upward with respect to the releasing needle 1, so as to insert its open head 3 in the space comprised between the portion 8b and the shank 2 of the releasing needle 1. It should be noted that the receiving needle 1b, in this lifting, is arranged with its head 3 between the rear protrusion 18b and the side 7b of the shank 2 of the releasing needle 1.
  • the receiving needle 1b prevents the portion 8b of the lamina 6b from being crushed completely by the loop of knitting 9 against the side 7b of the shank 2 of the releasing needle 1 and the first segment 13b defines a front abutment that prevents the latch 4 of the receiving needle 1b from rotating about the axis 4a, assuredly keeping open the latch 4 of the receiving needle 1b, as shown in particular in Figure 7 .
  • the inactive needle 1a is in a lower position with respect to the position occupied by the receiving needle 1b, but its head 3 is in any case preferably arranged between the rear protrusion 18a and the side 7a of the shank 2, and is thus "covered” by the rear protrusion 18a, so as to not interfere with the process for transferring the loop of knitting 9, as shown in particular in Figure 8 .
  • the releasing needle 1 is lowered and the receiving needle 1b is lifted, preferably to the position that corresponds to the held-stitch position.
  • the descent of the releasing needle 1 moves the receiving needle 1b so that it protrudes with its head upward from the portion 8b of the lamina 6b. Moreover, the descent of the needle 1 causes the loop of knitting 9, arranged around the laminas 6a, 6b, to slide along the third segment 15b of the portion 8b, moving it toward the shank 2 and bringing it into the head of the receiving needle 1b.
  • the head 3 of the receiving needle 1b protrudes upward from the portion 8b of the lamina 6b practically without interfering with the portion 8b of the lamina 6b of the releasing needle 1 and therefore without the need to produce the separation of its upper end from the shank 2 of the releasing needle 1. In this manner, the wear of the head 3 of the receiving needle 1b and of the lamina 6b of the releasing needle 1 is reduced significantly.
  • the two needles 1 and 1b can be lowered together below the knitting formation plane 21. During this lowering, the portions 8a, 8b of the laminas 6a, 6b, by engaging the strips, are moved into the inactive position.
  • the passage of the portions 8a, 8b of the laminas 6a, 6b from the active position to the inactive position after the transfer of the loop of knitting 9 can be achieved following the descent of the releasing needle 1 between the adjacent needles 1a, 1b, since the first segment 13a, 13b of the portions 8a, 8b of the laminas 6a, 6b engages the sides 10a, 10b of the blending region 10, as shown in Figures 10 and 11 .
  • the inactive needle 1a which does not take part in the transfer of the loop of knitting 9, can be used to reduce the extent of the elastic deformation of the portion 8a of the lamina 6a of the adjacent releasing needle 1 away from the corresponding side 7a of the releasing needle 1, so as to reduce the stresses to which the loop of knitting 9 to be transferred and the other lamina 6b are subjected.
  • the releasing needle 1 and the inactive needle 1a are lifted together, so that the releasing needle 1 slides within the loop of knitting 9 until it is moved against the resting shoulder 17b of the lamina 6b, whose portion 8b is in the active position, while the contact of the blending region 10 of the inactive needle 1a continues to limit the spacing of the portion 8a of the lamina 6a from the side 7a of the releasing needle 1.
  • Figure 12 illustrates the sequence of actuation, in the direction indicated by the arrow 30, of sets of three needles 1, 1a, 1b.
  • the needles have all been shown with the corresponding latch 4 open, without altering the fact that the latch 4 is open or closed on the head of the needles 3 depending on the operating conditions of the needles.
  • the sinkers 29 and/or the strips 27 engage the rear protrusion 18a, 18b of the second portion 14a, 14b of the portions 8a, 8b of the laminas 6a, 6b, assuredly preventing a compression of the portions 8a, 8b toward the shank 2 of the releasing needle 1 by virtue of the action of the loop of knitting 9.
  • the needles according to the invention are used in a dial of a machine with cylinder and dial, the needles are moved radially outward instead of being raised and radially inward instead of being lowered.
  • the particular structure of the needle according to the invention allows to provide said needle according to the invention with a reduced thickness, such as to allow its use in machines with high fineness (higher than 18 needles per inch).
  • the needle according to the invention can be used advantageously also on double-bed machines to transfer a stitch from one bed to the other also with transfer from one needle of one bed to an adjacent needle of the same bed without requiring relative movements between the beds and therefore avoiding the problems of precision and complexity in execution that these movements entail.
  • needles according to the invention with the possibility to transfer the stitches from either side of the needles on machines that can be actuated with an alternating motion allows to produce items of knitting with knitted regions of any shape with increasing or decreasing stitches, increasing their quality and degree of finish.
  • the needle according to the invention fully achieves the intended aim, since by limiting the sliding between the elastically flexible portion of the laminas and the head of the adjacent needle onto which the stitch or loop of knitting is to be transferred it reduces the wear of these components, achieving longer durability for the needle.
  • the covering of the head of the adjacent needles by the elastically flexible portion of the lamina of the releasing needle during the transfer of the stitch or loop of knitting ensures high precision and reliability in the operation for transferring the stitch or loop of knitting.
  • Another advantage of the needle according to the invention is that it can prevent the compression of the elastically flexible portions of the lamina against the shank of the needle thanks to the action of the stitch or loop of knitting to be transferred and/or prevent or limit the spacing of the elastically flexible portions of the lamina from the shank of the needle that must release the stitch or loop of knitting by means of the adjacent needle or by means of other elements of the machine on which it is mounted, achieving high versatility in actuation and use.
  • the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
