Definitions

  • the propulsion and retraction movement of the knitting needles is effected by knitting locks.
  • These knitting locks have curved tracks (lock passages) in which the needle feet engage. Once the knitting locks are moved in the machine longitudinal direction, the knitting needles move transversely to the machine longitudinal axis.
  • the prior art include knitting locks in which by means of locally superimposed castle passages the different needle drives, z. B. for Fang-Maschen-handed over, be realized.
  • the individual castle passages differ by different engagement heights on the feet of the needles.
  • the needle feet are brought into their height position by controlled pusher elements. (please refer DE 3537612 ).
  • the possible height positions of the needle feet ranging from completely submerged in the needle channel to the full foot height, which protrudes from the needle channel.
  • the DE-A-3327093 describes a knitting lock for sliding needles, which implements a three-way technique, ie in which the needles form a loop depending on the point of their selection in the knitting lock, form a tuck or do not participate in the knitting process.
  • the various castle passages are limited by four castle parts, with two of the castle parts only in the carriage reversal and only together, but not relative to each other are adjustable.
  • This knitting lock designed as a pusher lock is complex in construction.
  • the castle passages predominantly have a width corresponding to the needle foot width.
  • the invention has for its object to develop a knitting lock with at least two castle passages, which is structurally simple and has the least possible wear on the needle feet and on the lock parts.
  • the control part forms a kind of switch for the needle feet.
  • the width of at least one of the castle passages and thus on the game of the needle feet can be influenced by the direction of movement of the control part.
  • the control part formed as an angle piece has an identical contour to the lock part inner surfaces and is moved in the direction of the bisector of the angle between two surfaces of the control part, a lock passage of a single width is formed.
  • a different direction of movement of the bisector is selected, for example, perpendicular to one of the surfaces of the control part, a lock passage forms with a portion of a first width and a portion of a different second width. Whether the first or the second width is greater, depends on the areas of the control part or the direction of movement with respect to the surfaces.
  • needle feet are narrower or wider. This affects the needle function and the wear.
  • FIGS. 1a and 1b From the FIGS. 1a and 1b it can be seen that by means of a displaceable control part 1, which is moved in a straight line between two rigidly arranged lock parts 2 and 3 , two locally superimposed lock passages 4 and 4 ' can be formed. In both lock passages 4 and 4 ', the control feet 6 of the needles are detected at the same engagement level, namely at full foot level.
  • the lock passage 4 is bounded on one side by a plurality of mutually joined straight surfaces 21, 11, 12 and 25 or on the other side by a plurality of mutually joined straight surfaces 31, 32 and 33 .
  • the lock passage 4 ' is bounded on one side by the joined straight surfaces 21, 22, 23, 24 and 25 or on the other side by the joined straight surfaces 31, 13, 14, 15, 16 and 33.
  • Each straight surface is at a different angle than the straight surface to which it is attached.
  • the control part 1 is so far in the direction of the arrow V in the direction of movement shown by the dotted line 5 Fig. 1a shifted that its surfaces 13 and 16 abut against the contact surfaces 22 and 25 of the lock part 2.
  • the resulting lock passage 4 receives its upper contour through the surfaces 11 and 12 of the control part 1 and the surfaces 21 and 25 of the lock part 2.
  • the lower contour is formed by the surfaces 31, 32 and 33 of the lock part 3.
  • Fig. 1b is the control part 1 so far in the direction of the arrow V ' shifted by the dash-dotted line 5 shown that its surfaces 11 and 12 abut against the contact surfaces 31 and 32 of the lock part 3.
  • the resulting lock passage 4 ' receives its upper contour through the surfaces 21, 22, 23, 24 and 25 of the lock part 2.
  • Die lower contour is formed by the surfaces 13, 14, 15 and 16 of the control part 1 and the surfaces 31 and 33 of the lock part 3.
  • FIGS. 2a to 4b illustrate how the position of the direction of movement 5 to the bisector MS must be by the angle between the surfaces A and B of the formed as an angle control part 1, at least at a portion of the lock passage, here referred to as needle channel NKA or NKB , a well-defined width obtained on which a minimal clearance between needle butt and needle channel is realized.
  • Fig. 2a is the control part 1 on the lock part 2, so that the lower lock passage is open.
  • the surfaces A, A ' and A " and also the surfaces B, B' and B" are arranged parallel to each other.
  • the surfaces A and B, or A 'and B', and A “and B” are each arranged at the same angle to each other.
  • the needle channel widths NKA and NKB should have the same width.
  • the direction of movement 5 of the control part 1 lies in the direction of the bisecting line MS of the angle between the areas A and B.
  • Fig. 2b is the control part 1 in its direction of movement 5 so far in the direction of the arrow V 'shifted that the upper lock passage is opened.
  • the width of the needle channels NKA and NKB is the same.
  • the needle channel width NKB is weighted higher than the needle channel width NKA with respect to a minimum clearance between needle butt and needle channel.
  • the direction of movement 5 of the control part 1 moves away from the bisecting line MS in the direction of the perpendicular to the surface A.
  • the control part 1 is displaced in a direction perpendicular to the surface A direction.
  • Fig. 3b is the control part 1 in its direction of movement 5 so far in the direction of the arrow V 'shifted that the upper lock passage is opened.
  • the needle channel NKB is narrower than the needle channel NKA.
  • Fig. 4a which in terms of configuration substantially the Fig. 2a
  • the needle channel width NKA is weighted higher than the needle channel width NKB with respect to a minimum clearance between needle butt and needle channel.
  • the direction of movement 5 of the control part 1 moves away from the bisecting line MS in the direction of the perpendicular to the surface B.
  • the control part 1 is displaced in a direction perpendicular to the surface B extending direction.
  • Fig. 4b is the control part 1 in its direction of movement 5 so far in the direction of the arrow V 'shifted that the upper lock passage is opened.
  • the needle channel NKA is narrower than the needle channel NKB.
  • a knotter 100 is moved in the direction of the arrow X.
  • a Austriebsteil 30 and a limiting member 40 are rigidly secured.
  • Needle counters 42 and 44 are, according to the prior art, movably arranged.
  • a castle passage changing control part 10 has been moved in its direction of movement 50 so far in the direction of arrow Y in a straight line until it came to the needle sink 42 to the plant.
  • a likewise changing the lock passage control part 10 ' has been moved in its direction of movement 50' so far in the direction of arrow Z in a straight line until it came to the needle sink 44 to the plant.
  • needle feet 60 can be brought from their basic position GP to the needle projection N1 , which is determined by the ejection part 30.
  • Fig. 5b is the lock passage changing control part 10 in its direction of movement 50 so far in the direction of the arrow V 'has been moved straight until it came to the ejection part 30 to the plant.
  • the needle feet 60 can be brought from its basic position GP to the needle outlet N2 , which is determined by the control parts 10 and 10'.
