Definitions

  • the present invention relates to a straight-bar knitting machine with means for facilitating the formation and casting-off of stitches.
  • a prior patent application in the name of the same Applicant discloses a straight-bar knitting machine provided with means for facilitating the formation and casting-off of stitches; said means are substantially constituted by a plurality of secondary sinkers provided in an additional needle holder and slideable in a plurality of slots formed correspondingly with respect to the knitting needles.
  • the secondary sinkers are provided with a heel located in an upward region; actuation means, provided on the carriage of the straight-bar knitting machine, engage said heel.
  • the secondary sinkers act constantly on the knitting and cannot be deactivated or activated in a different position; this fact can sometimes hinder the formation of the knitting.
  • a principal aim of the invention is indeed to eliminate the drawbacks described above by providing a straight-bar knitting machine with means for facilitating the formation and casting-off of the stitches, allowing to automatically facilitate the activation of the secondary sinkers, moving them into different positions or out of action, during the stroke of the carriage.
  • a particular object of the invention is to provide a straight-bar knitting machine wherein the carriage is not forced to perform a stroke that is longer than the region affected by the secondary sinkers that must be positioned.
  • Another object of the present invention is to provide a straight-bar knitting machine wherein the positioning of the secondary sinkers to facilitate stitch formation is stable and can be maintained once it has been assumed.
  • Another object of the present invention is to provide a straight-bar knitting machine capable of giving the greatest assurances of reliability and safety in use by virtue of its particular constructive features.
  • a straight-bar knitting machine with means for facilitating the formation and casting-off of stitches, according to the invention, comprising two needle holders arranged in the shape of an inverted V and on which needles are slidingly mounted, and at least one additional needle holder located on at least one of said needle holders and supporting a plurality of secondary sinkers for facilitating the formation and casting-off of the stitches, characterized in that it comprises secondary sinker positioning means that are supported by the carriage of the machine and can be actuated by motor means that can be activated independently during the stroke of said carriage.
  • the straight-bar knitting machine with means for facilitating the formation and casting-off of the stitches comprises two needle holders 1 and 2, arranged so as to form an inverted V, in a per se known manner. Needles 3 for forming stitches in a conventional manner are slideable on the needle holders 1 and 2.
  • a first additional needle holder 4 and a second additional needle holder 5 are formed respectively proximate to the vertex of the needle holders 1 and 2 and are arranged symmetrically with respect to the plane of symmetry between the needle holders 1 and 2.
  • the additional needle holders 4 and 5 form a plurality of slots, designated by the reference numeral 6 for both needle holders; secondary sinkers, generally designated by the reference numeral 10, are slidingly accommodated in said slots.
  • the secondary sinkers 10 are slideable inside the slots 6 and are kept in position by a strip 11 that runs longitudinally with respect to the extension of the needle holders, so as to keep all the secondary sinkers in position.
  • the secondary sinkers 10 have a foot 12 inclined with respect to the central portion or stem 13 of the secondary sinker and ending with an engagement end 14 having the purpose of engaging the stitch being formed in order to facilitate the formation and casting-off of the stitches.
  • a heel 15 is formed at the opposite end and engages means, generally designated by the reference numeral 20, for positioning the secondary sinkers; as more clearly shown in figures 2 to 4, said means are advantageously constituted by cam sliders 21 that support the cams 22, which engage, during the stroke of the carriage, the heels 15 and can be positioned by virtue of the presence of a positioning pin 23 engageable in contoured slots 24 formed on a bar 25 movable by virtue of the action of motor means 27 that drive a gear 28 engageable with a rack-like portion 29 formed by one edge of the bar 25.
  • the contoured slots 24 in practice change the position of the cam sliders 21 and consequently allow to vary the position of the secondary sinkers.
  • figure 2 illustrates the position of the cams for placing the secondary sinkers in the active position during the stroke of the carriage in one direction
  • figure 3 illustrates the position of the cam sliders 21 for positioning the secondary sinkers during the stroke of the carriage in the other direction.
  • Figure 4 illustrates the position of the cam sliders 21 for keeping the sinkers in the deactivated, i.e. raised, position.
  • the motor means 27 can be activated independently on the two needle holders and can be actuated directly during the stroke of the carriage with a program that can vary in each instance.
  • Another important aspect of the invention resides in the fact that the sinkers 10 are provided with elastic means for stably positioning them.
  • Said elastic means are formed directly on the stem 13 of the secondary sinker and are constituted by a flexible tab 30 formed by a recess 31 in the material constituting the stem 13.
  • the flexible tab 30 has a loose end 32 and a concave portion 33 towards the leading region; these parts are engageable with an abutment element 35 formed in the slot.
  • the secondary sinker When the end 32 engages the element 35, the secondary sinker is in the raised position and therefore is in practice deactivated, whereas when the element 35 engages the concave portion 33 the secondary sinker is in the lowered position and therefore in the preset knitting position.
  • the particular structure of the secondary sinkers, provided with the flexible tab 30, allows to obtain a stable position for said secondary sinkers.
  • the materials employed, as well as the contingent shapes and dimensions may be any according to the requirements.
