Control arrangement for warp knitting machine guide bars

Control arrangement for the displacement of a guide bar of a warp knitting machine having a main shaft, comprising:

• a setting motor for axially displacing said guide bar;
• and
• a schedule transmitter coupled to said main shaft for generating target lapping values for a displacement schedule, in response to angular displacement of said main shaft, said schedule transmitter being coupled to and operable to control said setting motor in accordance with said target lapping values, said schedule transmitter including:
• (a) an input arrangement for providing a characteristic signal signifying characteristic data for a selected lapping pattern;
• (b) a storage means having a first storage section for storing data signifying a selectable plurality of transition curves for regulating overlap and underlap displacements;
• (c) a computer means coupled to said first storage section and responsive to said characteristic signal for processing sequentially data of at least two of the transition curves to form a displacement function providing displacement values related to revolution of said main shaft;
• and
• (d) an output arrangement coupled to said main shaft and said computer means for selecting said displacement values of the displacement function in response to angular rotation of the main shaft to provide said target lapping values.
