Abstract
The pattern mechanism uses final control elements which are controlled in accordance with a pattern for producing a controlled shogging motion of the guide bars or strips. Additional program-controlled control elements are added to avoid a loss in the shogging stroke. These latter elements are optionally controlled via a program carrier and prevent the pattern yarns controlled by the guide bars from being positioned into a faulty sinker lane irrespective of the length of the shogging stroke. The stroke of one correcting element can be, for example one quarter of the unit stroke of the main control elements while the stroke of the other added element can be one half of the stroke unit.
Claims7
In combination with a guide bar of a warp knitting machine, a pattern mechanism comprising
- an elongated flexible tension element secured to said guide bar at one end to a fixed point at an opposite end;
- a plurality of main control elements for selectively varying the effective length of said tension element relative to said guide bar, each said control element having a stroke for producing a shogging motion on said guide bar equal to a multiple of a given value;
- and
- at least one supplemental program-controlled control element for selectively varying the effective length of said tension element relative to said guide bar, said program-controlled control element having a stroke for producing a shogging motion on said guide bar equal to a fraction of said given value.
In combination with a plurality of sinkers of a warp knitting machine disposed in equi-spaced relation at a given sinker spacing and a guide bar disposed over said sinkers;
- a pattern mechanism comprising
- an elongated flexible tension element secured to said guide bar at one end and to a fixed point at an opposite end;
- a plurality of main control elements for selectively varying the effective length of said tension element relative to said guide bar, each said control element having a stroke for producing a shogging motion on said guide bar equal to a multiple of said sinker spacing;
- and
- at least one supplemental program-controlled control element for selectively varying the effective length of said tension element relative to said guide bar, said supplemental control element having a stroke for producing a shogging motion equal to a fraction of said sinker spacing.
