Description

The present invention relates to a straight knitting machine

  having bedbugs arranged in the form of a roof,

  equipped with individually movable needles

  cune a felling comb consisting of a plurality of reported felling partitions as well as mesh elements connected to knitting locks and which, during their movement along the needle beds, exert on the knit placed between the combs

  slaughter a pressure directed vertically downwards.

  Because such straight knitting machines work, when applied to the manufacture of parts

  shaped knitted raw materials, of structural

  similar items, without devices or special drawing counterweight, there is the disadvantage that, in the case of particular modes or sequences of knitting, the knit freely hanging from the needle hooks is accumulated under the effect of its own tension and the Ascending needles penetrate into the already formed meshes. This results in mechanical disturbances that have

  a detrimental influence on the knitting process.

  Auxiliary means are already known

  that the knit already pulled down is held in position.

  Thus, for example, in German Patent No. 613,864, the needle guiding body is provided with a card lining whose tips are obliquely arranged.

hold the knitting.

  In German Utility Model No. 1,661,944, an improvement of this type has been described in which the tips placed completely at the top of the cardboard ribbon can only perform a limited movement and the knit is

held rigidly in position.

  The solutions indicated for retaining the knitting do not pre-

  feel, however, no relation to the press-mesh elements

  involved in the manufacture of raw knitted

  structural threads or similar articles. The aforesaid press-mesh elements have been described, for example,

  in Swiss Patents Nos. 375,825, 516,676, and 573,001.

  The object of the invention is to enable, with

  as simple as possible, in flat knitting machines

  lines with press-mesh elements, to maintain

  right in position the knit once pushed down.

  According to the invention, this problem is solved by the fact that the front faces of the slaughter walls, which are oriented towards the knit, comprise retaining hooks arranged in the form of teeth, and that the horizontal spacing between the press-mesh elements and the hooks or retaining teeth is inferior

to the thickness of the knit.

  Advantageously, it is provided that between each group of toothed felling partitions is disposed at least one non-toothed felling wall, the outer contour of which corresponds to an envelope curve passing through the tips of the teeth of the partitions.

slaughtered teeth.

  An advantageous embodiment of reported felling partitions is known from Swiss Patent No. 575,031 of the applicant. Other advantages and characteristics of the invention

  will be highlighted, in the rest of the description, given to

  As a non-limitative example, with reference to the accompanying drawing in which: Figure 1 is a detailed section of the beds of a straight knitting machine, including reported slaughter walls. FIG. 2 is a view along the arrow A of the

figure 1.

  The needle beds 1 and 2 (FIG. 1) of a flat knitting machine each consist of a basic body 3, which is

  provided on its upper side with a plurality of parallel grooves

  4, in which are guided individually movable needles. Reported felling partitions 7 are housed in a plurality of grooves 6 which are also parallel and offset laterally by a half-needle pitch. A wire 8 forming a common mesh cutting edge, and an auxiliary wire 9 connect all the felling partitions along the length of the needle bed and form the actual slaughter comb of the machine.

knit straight.

  A simplified form of a mesh element 10, moving with the knitting locks (not shown) along the needle beds is placed in the space between the

  beds 1 and 2 arranged in the form of a roof.

  On the left-hand side of Figure 1, the arran-

  Fencing partitions 11 having retaining hooks 12 of teeth-shaped, in which the knit 13 is pushed and hooked by the press-mesh element 10 during its movement along the needle beds. To better show the hooks or retaining teeth 12, it is not shown the knitting on the left side of Figure 1. It can be seen in Figure 2 how is carried out the distribution of groups of felling partitions with teeth 11 and without teeth 7. To ensure an unimpeded passage of the mesh press member 10 in its relative movement along the needle beds, the outer contour of the non-toothed slaughter walls 7 must correspond to a curve-envelope passing through the spikes of

  teeth 14 (FIG. 1) toothed slaughter walls 11.

  It is obvious that the felling partitions 7 and 11 can be arranged in any way and are identical for

the two beds.

  Of course, the present invention is not limited to the embodiments described and shown; it is capable of numerous variants accessible to those skilled in the art, depending on the applications envisaged and without

  departs from the spirit of the invention.
