Abstract
In a warp knitting machine at least one swingable guide bar is driven in a shogging direction. This displacement is achieved through a drive member via a hinged push rod in dependence upon a path time function. This path time function is formed by overlapping a ground function with a compensation function. The ground function is the targeted displacement movement of the guide bar for proper lapping. The compensation function compensates for an axial mislap and possible collision during the swing-through of the guide bar. The compensation occurs at least during that segment corresponding to the passage of the guides through the needle gaps. Preferably however, compensation occurs over the entire ground function. This compensation substantially reduces the danger of collision between the guides and the needles.
