Definitions

  • the present invention relates to a needle for transferring stitches from said needle to adjacent needles for knitting machines for hosiery or the like.
  • needles In the field of knitting machines for hosiery or the like, 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.
  • the lamina has, on each side of the needle, a portion that can flex elastically from an inactive position, in which it is flattened against the corresponding side of the shank of the needle, to an active position, in which it is spaced from the corresponding side of the shank of the needle, so as to define the receptacle in which the needle designed to receive the stitch or loop of knitting must be inserted.
  • the transition of the elastically flexible portions of the lamina from the inactive position to the active position, in this type of needle, is obtained simply by means of the elastic reaction of the elastically flexible portions of the lamina, which in the absence of forces that act thereon are shaped so as to be in the active position.
  • the transition to the active position of the elastically flexible portions of the lamina occurs as a consequence of the elastic reaction of the elastically flexible portions when the needle is in such a position that the sides of the slots of the needle holder that accommodate the needle or the sinkers do not hinder the free passage of the elastically flexible portions of the lamina into the active position.
  • Such needle during testing, has proved to be susceptible of improvements aimed mainly at increasing its possibilities of actuation as regards the transition of the elastically flexible portions of the lamina from the inactive position to the active position or vice versa and the reduction of the stresses of the lamina and of the loop of knitting to be transferred.
  • the aim of the present invention is to provide a needle for transferring stitches from said needle to adjacent needles for knitting machines for hosiery or the like in which it is possible to actuate, according to the requirements, the transition of the elastically flexible portions of the lamina from the inactive position to the active position or vice versa even independently of the adjacent elements of the machine.
  • an object of the invention is to provide a needle that reduces the stresses on the stitch or loop of knitting to be transferred and on the portions of the needle that actuate the transfer of the stitch or loop of knitting.
  • Another object of the invention is to provide a needle that ensures high reliability in transferring the stitch or loop of knitting.
  • Still another object of the invention is to provide a needle that is highly versatile in use.
  • Another object of the invention is to provide a needle that can have a reduced thickness, so as to allow its use on high-fineness machines, particularly in machines with more than 12 needles per inch.
  • a needle for transferring stitches from said needle to adjacent needles for knitting machines for hosiery or the like according to claim 1.
  • the needle according to the invention generally designated by the reference numeral 1, comprises: a shank 2, which has an elongated shape, a head 3, and a latch 4.
  • the head 3 is arranged at a longitudinal end or upper end of the shank 2 and is shaped like a hook that is open toward the front side of the shank 2, in a manner similar to known types of needles.
  • the latch 4 is hinged to the shank 2 proximate to the head 3, about a pivoting axis 4a that is substantially perpendicular to the longitudinal axis of the shank 2, and rotatable about the pivoting axis 4a to open or close the head 3, as in known types of needles.
  • the shank 2 has, along its extension, on its front side and proximate to its longitudinal end, or lower end, that lies opposite with respect to the head 3, at least one heel 5, which protrudes from its front side and can engage, in a per se known manner, the needle actuation cams provided in the knitting machine for hosiery or the like on which the needle 1 is to be fitted.
  • the needle according to the invention comprises at least one lamina 6a, 6b, which is connected to the shank 2 and has, on each of the two opposite sides 7a, 7b of the shank 2, below the latch 4, a portion 8a, 8b, which is elastically flexible from an inactive position, in which it is close to the corresponding side 7a or 7b of the shank 2, as shown in particular in Figure 2 , to an active position, in which it is spaced from the corresponding side 7a or 7b of the shank 2, as shown in particular in Figure 1 .

  • the third segment 15a, 15b, at least proximate to the upper end 12a, 12b of the corresponding lamina 6a, 6b, fixed to the corresponding side of the shank 2, is located in front of the head 3.
  • the region of the needle 1 that is occupied by the portions 8a, 8b of the laminas 6a, 6b has, along the anteroposterior direction, an increased space occupation toward the front side of the needle with respect to the contiguous regions of the shank 2.
  • the shank 2 between the latch 4 and the end of the portion 8a, 8b of the lamina 6a, 6b that is directed toward the head 3, has a region 10 for blending the shank 2 with the portion 8a, 8b of the lamina 6a, 6b.
  • the blending region 10 is shaped like a wedge that tapers toward the head 3.
  • the blending region 10 has a front face 10c, which is inclined with respect to the longitudinal axis of the shank 2 so as to blend the region occupied by the portions 8a, 8b of the laminas 6a, 6b with the segment of the shank 2 that is arranged above.
  • Said front face 10c of the blending region 10 has a curved lower segment that blends it with its base side.
  • the blending region 10 is delimited laterally by sides 10a, 10b that are shaped, at least for a segment starting from their upper end, like a plane that is inclined with respect to the longitudinal axis of the shank 2 and move mutually closer progressively toward the head 3.
  • the lower end of the blending region 10 is wider than the distance between the two opposite sides 7a, 7b of the shank 2 in regions that are contiguous to the blending region 10.
  • each lamina 6a, 6b i.e., the end that is directed toward the head 3, is fixed to the blending region 10 proximate its base.
  • the cam 33 can engage selectively the heel 32a or the heel 32b, so as to cause the transition from the active position to the inactive position of the portion 8a or of the portion 8b of the lamina 6a or 6b, which is located on the opposite side 7a or 7b of the shank 2 with respect to the side directed toward the adjacent needle to which the loop of knitting is to be released, independently of the position of the portion 8b or 8a of the other lamina 6b, or 6a.
  • cam 33 that faces the side of the needle holder 40 of the machine from which the heels 32a, 32b protrude and can move on command along a direction that is parallel to the longitudinal axis of the shank 2 with respect to the needle 1, so as to engage the heel 32a or the heel 32b.
  • the cam 33 has been shown in solid lines in the position in which it can engage the heel 32a and in dashed lines in the position in which it can engage the heel 32b.
  • the profile of the cam or cams 33 is contoured in relation to the profile of the needle actuation cams that engage the heel 5 of the needles so as to cause, during the process for the release of the loop of knitting from the needle 1 to an adjacent needle, a movement of the heel 32a or 32b toward the longitudinal end of the shank 2 that lies opposite the head 3 with respect to the shank 2. This can occur both while the needle I is stationary and while it is being moved longitudinally with respect to the needle holder 40.
  • 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 release 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, 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, can move away by elastic reaction from the shank 2 with their portion 8a, 8b.
  • the heel 32a of the lamina 6a which is the lamina directed toward the inactive needle 1a, engages the cam 33, which by causing a movement of said heel 32a toward the end of the shank 2 that lies opposite the head 3 with respect to said shank 2, causes the passage of the portion 8a of the lamina 6a from the active position to the inactive position, if the portion 8a has previously moved into the active position, or prevents the portion 8a of the lamina 6a from reaching the active position.
  • the releasing needle 1 arranges itself with the supporting shoulder 17a, 17b proximate to the knitting formation plane 21, only the portion 8b is in 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 supporting shoulder 17a, 17b, is widened progressively in a manner suitable to be crossed by the receiving needle 1b.
  • the presence of the blended region 10 ensures a gradual widening 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 upwardly 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 flattened 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.
  • 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 upwardly 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 can protrude upwardly from the portion 8b of the lamina 6b without interfering with the upper end 12b of the lamina 6b 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 also reduced significantly.
  • the two needles 1 and 1b can be lowered together below the knitting formation plane 21.
  • the portion 8b of the lamina 6b by engaging the side of the slots of the needle holder 40 that accommodate the needle 1, is returned to the inactive position.
  • Figure 3 shows the actuation sequence, in the direction indicated by the arrow 30, of groups of two needles 1, 1b.
  • the needles have been all shown with the corresponding latch 4 open, without altering the fact that the latch 4 will be open or closed on the head 3 of the needles depending on the operating conditions of the needles.
  • the presence of the supporting shoulder 17a, 17b allows to transfer loops of knitting 9 also above the knitting formation plane 21, since said supporting shoulder 17a, 17b achieves by itself the correct positioning of the loop of knitting 9 to transferred, avoiding its descent along the shank 2 of the releasing needle 1.
  • the passage of the portion 8b of the lamina 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 with respect to the receiving needle 1b, since the first segment 13b of the portion 8b of the lamina 6b engages the side 10a of the blending region 10 of the receiving needle 1b.
  • 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 with a reduced thickness, such as to allow its use in machines with high fineness (higher than 18 needles per inch).
  • needles according to the invention with the possibility to transfer the stitches on 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 allowing to actuate, according to the requirements, the passage of the elastically flexible portions of the lamina from the active position to the inactive position or vice versa, it makes its actuation more versatile.
  • the possibility to actuate individually the passage of the elastically flexible portions of the lamina from the active position to the inactive position allows to limit the widening of the loop of knitting to be transferred, allowing to reduce the stresses on the loop of knitting and on the parts of the needle that actuate the transfer of the loop of knitting.
  • the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
