Definitions

  • the present invention relates to a method and a flat knitting apparatus for manufacturing rib knit fabric by means of two rows of needles arranged at an angle to each other, the needles of each row operating successively, whereby the finished knitted fabric is held down by holding-down plates of the one row of needles.
  • Rib knit fabric can be manufactured with the known hand operated flat knitting, devices of this kind in a useful and trouble-free manner only if double-bed knitting apparatus are used.
  • Auxiliary devices for single-bed knitting apparatus for the manufacture of rib knit fabric have already been proposed, but they still have many disadvantages,'such as complicated structure, difficult manipulation and troublesome operation.
  • the needles of the auxiliary device are generally arranged in a fixed manner.
  • the needles of the auxiliary device must be mobile relative to the needles of the main apparatus, this movement is executed simultaneously for all the needles of the auxiliary device, or the single needles themselves are manufactured of elastic material, whereby they then are easily bent or are even broken. vOften special turning combs have to be used for the auxiliary device.
  • the object of the invention is to overcome these disadvantages.
  • a method of the said kind which comprises alternately forming rows of meshes by the needle row disposed at the main knitting apparatus and holding down them by holding down plates disposed at the main knitting apparatus and the second row of needles disposed before said main knitting apparatus, the needles of the row of the main knitting apparatus as well as the needles of the row of needles disposed before the main knitting apparatus being brought separately and one afterflthe other in the forward and in the rearward position for the formation of the meshes by means of a generally known slide or carriage with needle guides and individual to the respective row of needles.
  • a further object of the invention is to provide a flat knitting apparatus of the kind above mentioned, in which an auxiliary device is used consisting of a needle bed with guide grooves and actuated by a slide-like movable control element before the needle bed of said main knitting apparatus and outside of the range of movement of said holding-down plates of the main knitting apparatus and that they are movably and yieldingly held toward the bottom side of the guide grooves of the needle bed, for cooperation with said holding-down plates the needles of the row of the main knitting apparatus and the needles of the row of needles of the auxiliary device being arranged in the same vertical plane between the adjacent holding-down plates of the main knitting apparatus.
  • Fig. 1 is a plan view of an embodiment of the flat knitting apparatus with auxiliary device
  • Fig. 2 shows the same apparatus in vertical cross section according to line V-V of Fig. 1,
  • Fig. 3 shows the needle bed of the auxiliary device in vertical cross section as in Fig.
  • Figs. 4 and 5 show some needles of the auxiliary device with their single leaf springs as yielding abutments in plane view and in side elevation
  • Figs. 6 and 7 show a holding-down plate for the knitted fabric with a part of the needle bed and of the slide of the main knitting apparatus in side elevation, partly in vertical section, and in lower and lifted position,
  • Fig. 8 shows an embodiment of the auxiliary device slide in plane view from the underside.
  • Figs. 1 and 2 is the under frame 1 of the main knitting apparatus with the needle bed 2, the tongue needles 3 carried in parallel grooves, the guide rails 4 for the slide or carriage 5 arranged rectangularly to the needles 3 and the slide or carriage 5 with the handle 6.
  • a holding-down plate 7 is pivotally mounted on a common axis or on pivot pins 8.
  • Each of said holding-down plates 7 has at its rear end an upward directed lug or extension 9 and a downward directed plate-like extension-piece 10. This latter plate-like extension-piece 10 is guided in a slot 11 of the needle bed 2 and has a bore 12 for a pivot pin 8.
  • the front edge or abutment part 13 for the knitted fabric of each holding-down plate 7, extending arc-shaped downwardly, has at its top a somewhat protruding part 14 which passes over with a recess 15 into the abutment part 13 for the knitted fabric and forms a hook for holding down the knitted fabric.
  • the parts 13, 16 are guided in a slot 19 of the needle bed 2 or of the underframe 1.
  • the return spring 18, which is a helicoidal spring abuts with one end against the radial end cross-piece 17 and with the other end against the under face of the needle bed 2 at either side of the guide slot 19.
  • the holding-down plates 7 repose with their central, horizontal part between the plate-like extension piece 10 and the abutment part 13 on the upper face of the needle bed 2, which may be provided at this point with an elastic layer 43 of felt, rubber or the like.
  • each holding-down plate 7 for the knitted fabric is controlled by a cam-like abutment 21 fixed by means of an angular bracket 20 at the slide or carriage 5.
  • a cam-like abutment 21 fixed by means of an angular bracket 20 at the slide or carriage 5.
  • an auxiliary device with needle bed 23, tongue needles 24, slide rails 25 for a slide or carriage 26 with handle 27 is detachably mounted by means of vertical rails 22 making use of bearing rails 28 and screws 29 with wing nuts 30.
  • the guide grooves 31 for the tongue needles 24 in the needle bed 23 of the auxiliary device become somewhat deeper towards the top, so that the needles grooves 31 for the needles 24 have some clearance in the direction towards the I main knitting apparatus.
  • the upper slide rail 25 for the slide 26 can, in its character of upper abutment for 'the needles 24, be arranged in such a way that it has a somewhat greater distance from the bottom of the guide 24 than. the lower slide rail 25.
  • Each needle 24 is pressed by 'means of a' laminated spring against the upper slide rail 25 as an upper.abutment and is held yieldingly in this position in which it releases then the knitted fabric held by the hook-shaped parts of the holding-down plates 7 at 15 of the main knitting apparatus. Only when in their upper position a knitting mesh is formed by the tongue needles 3 of the main knitting apparatus, the needles 24 are swung by the knitting thread somewhat in the direction towards the main knitting apparatus against the influence of their holding springs 32. After the tension of the knitting thread is released the needles 24 are pushed back by the laminated springs 32 in their normal position according to Fig 2.
  • the slide or carriage 26 of the auxiliary device is provided in known manner with needle guides 33, 34 and with a needle bridge 35, adjustable in transverse direction to the slide 26.
  • needle guides 33, 34 and with a needle bridge 35, adjustable in transverse direction to the slide 26.
  • guide members 36 which can be swung upward and which are fixed at pivoted levers 37, and which can be swung together with these levers around a pivot 38.
  • the pivoted levers 37 extend with pins through slots 39 of the cover plate of the slide 26 of the auxilary device and may be used for the adjustment of the guide members 36, knobs 40 being provided for this purpose on the end of the cited pins.
  • the adjustable needle bridge 35 can be adjusted by means of a pivoted lever 41 with knob 42 from the upper side of the slide 26 of the auxiliary device or laterally of this latter for the straight-line adjustment by means of a straight guide and excentric pin and slot guide.
  • the pivoted lever 41 may e.g. be provided with two pins, one of which is connected rotatably to the adjustable-needle bridge 35 and the otherbeing guided with its end in a transverse slot of the slide 26, so that the lever with a range of movement of 180 adjusts the needle bridge in its final position to the smallest respectively the largest size of the meshes. In the middle position of the needle bridge 35, shown in Fig 4, it guarantees a middle size of the meshes.
  • a flat knitting apparatus with a main needle bed and a supplemental needle bed, both having parallel guide grooves for the needles, a main needle row and a supplemental needle row, the needles of which being longitudinally slidably disposed in said guide grooves of the corresponding needle bed for reciprocated movement for manufacturing knit fabric including means for actuating said needles in each needle row one after another for knitting operation, holding down plates for the finished knitted fabric between the needles of the main needle row at the needleroutlet side of the main needle bed, the supplemental needle bed being disposed with its needle outlet side before the needle outlet side of the main needle bed and angularly to the latter, the needles of the supplemental needle row being longitudinally slidably disposed in a plane somewhat spaced from the largest longitudinal extension of said holding down plates and staggered to said opposite holding down plates of the main needle bed, said means for actuating the needles of the supplemental needle row including a needle actuating slide slidably disposed upon the corresponding needle bed, a yieldable guide abut
