Definitions

  • the invention relates to knitting machines of the type specified in the preamble of claims 1 and 7.
  • Knitting machines of this type which may be formed as a circular or flat knitting machines, od as a needle cylinder, dial, flat bed. Like. Trained and provided with a plurality of parallel grooves bed. In the grooves predominantly designed as tongue or slide needles and provided with feet knitting tools are slidably mounted. The production of knitwear with patterns takes place in that the feet of the knitting tools are optionally distributed at least one work site to one of at least two, predetermined by lock parts of a castle tracks. One of these tracks leads the knitting tools z. For example, in a for receiving a thread, a sliver od. Like.
  • pattern or selection means For pattern distribution of the knitting tools on the various tracks are pattern or selection means, which are known in numerous variants and for acting on the knitting tools or these individually assigned, in the knitting tools themselves or at least in the same grooves of the bed like these arranged bumpers, sinkers , Control springs, bending oscillators od.
  • Serve which can be brought by mechanical, pneumatic, electrical, magnetic or electromagnetic means individually and sequentially in one of two or three positions, thereby the associated knitting tools in one of two or three lanes steer (eg DE 15 85 243 A1 , DE-PS 1 173 609 . DE 21 15 332 C3 . DE 21 64 632 A1 . DE 37 12 673 C1 . DE 16 35 844 C3 . EP 0 319 007 B1 ).
  • each selection step for a knitting tool must be made within a very short period of time in the case of high performance knitting machines, e.g. B. 0.5 ms to 1.0 ms, it is also known juxtaposed knitting tools, control boards or the like. With arranged at different heights feet and the selector in each of these heights od with a control in the form of a individually controllable dial blade. to be provided (eg. DE 21 17 713 C3 ). Thereby, the time periods available for a selection step can be multiplied and the selection operations can be performed with a greater certainty.
  • a hitherto unsolved problem with regard to the pattern-based selection of knitting tools arises when knitting machines with small pitches or high finenesses are used. While pitch is understood to mean the center distance of two knitting tools lying side by side in bed, the fineness indicates the number of needles in the bed next to each other per inch. A 60s fineness thus means z. Example, that 60 needles per inch or 5655 knitting tools are arranged on the circumference of a needle cylinder having a diameter of 30 ", resulting in a pitch of 0.4 mm. The thickness of a web and a knitting tool in such a case is only approx. 0.2 mm instead of 0.4 mm or more with a fineness of E 30.
  • a safe selection of such fine knitting tools can be carried out at comparatively low machine speeds and / or purely mechanical selection devices B. Only periods of about 0.2 ms to 0.5 ms are available, safe selection only possible if the knitting tools, control boards or the like., As provided in the above example, with arranged at different heights feet However, it is undesirable because it requires a complex machine design.
  • knitting machines are known whose knitting tools are controlled exclusively by lock parts and therefore no pattern or selection devices exhibit.
  • the knitting tools are controlled here by their feet successively reaching the area of cam curves (eg DE-PS 535 173 ).
  • locks with a plurality of stacked lock channels are known in this context, in each of which a foot of a knitting tool is guided. Depending on the height at which the feet are arranged on the knitting tools, these can each be assigned to a selected one of the lock channels. It is known z.
  • Example to distribute the feet of the knitting tools with a so-called oblique or diagonal insert and with single or double arrangement at several heights (eg. S.
  • a knitting machine is known from US 1,719,121 A known. In each case two adjacent knitting tools are selected by a common selection board. According to the US 1,809,057 A For example, this knitting machine is used for the production of patterned knitwear and therefore has a pattern device for driving the selection boards.
  • the grooves of the needle bed in which the selection boards are mounted are twice as wide as the grooves for the knitting tools.
  • the US 2,203,711 A describes a knitting machine with alternating different knitting needles, one of which is shorter and provided with an actuating foot and the other longer and provided with two operating feet. The shorter needle can be driven by the longer needle.
  • the present invention Based on this prior art, the present invention, the technical problem of proposing knitting machines of the genera initially described, by means of which even with any freely selectable patterns provided knitwear can be made without a significantly increased design and cost incurred must be, if great subtleties are desired.
  • the invention is based on the confirmed by experiments knowledge that in knitwear that with great subtleties of z. As E50 or E60 are made, a pattern changing from stitch to stitch pattern is not perceived in the manner as for a product with lower fineness of z. B. to E30 or less applies. Therefore, if two or more, immediately adjacent knitting tools are selected simultaneously and in the same way according to the invention in each selection step, then this results in the significant advantage that on the one hand the time available per selection step is multiplied and, on the other hand, the selection of the knitting tools is made with the same components can be used, which have been commonly used for knitting tools with low fineness.
  • the patterning of knitwear with great finenesses therefore does not lead, or at least not significantly, to increased design and cost. The fact that the pattern can only be changed after every second or more stitch hardly appears optically.
