Abstract
In a method for manufacturing a warp knitted fabric, the guides can also be displaced by one needle space (pitch) in addition to the overlap and underlap shog of the guide bar, so that the guides are not only selectively displaceable during the underlap shog, but also selectively during the overlap shog. A warp knitting machine for the purpose of carrying out the method comprises at least one thread system which consists of pattern threads laid in intermixed, varying patterns. These pattern threads have underlaps of n, n+1 and n-1 needle spaces and can produce a float and/or a twill. The number of pattern possibilities can be increased in this manner.

Method for manufacturing a warp knitted fabric on a warp knitting machine having on at least one guide bar a plurality of guides displaceable by one needle space additional to an overlap and underlap shog of the guide bar, comprising the steps of:
- shogging the guide bar during an overlap and underlap interval in each operational cycle;
- displacing during the underlap interval in each operational cycle a first group of the guides selected in dependence upon a predetermined pattern;
- and
- displacing during the overlap interval in each operational cycle a second group of the guides in dependence upon the predetermined pattern.
Warp knitting machine comprising:
- at least one guide bar;
- a displacement control device coupled to said guide bar for displacing said guide bar as a unit;
- a plurality of guides mounted on said guide bar for allowing individually selectable displacements of one needle space;
- and
- a control device coupled to said guides and having a program controlling unit for selecting in each operational cycle in dependence upon a predetermined pattern ones of said guides, said program controlling unit being operable to select in each operational cycle a first and second group of the guides to be displaced by the control device during underlap and overlap shogs, respectively.
Warp knitted fabric comprising:
- a fabric base;
- and
- at least one thread system having pattern threads laid in intermixed, varying patterns, said pattern threads comprising underlaps of n, n+1 and n-1 needle spaces, the pattern threads being selectively laid as a float, a twill, or a float and twill.
