Abstract
A process or apparatus can control thread provision in a warp knitting machine by means of a computer (6). The computer operation involves pattern data (MD) supplied as a sequence of numbers. These numbers are provided to a recognition routine (ER), which for every warp course (line W) determines the lapping type (LA) that should be formed and the shogging distance (SW) prescribed. Tables are stored for providing a thread provision value (FZ) for each combination of lapping type (LA), thread take-off value (WA), and a shogging distance (SW). Based upon (a) the determined lapping type, (b) the inputted fabric take-off value, (c) the inputtable external operating parameters or influences, and (d) the determined shogging distance, the thread provision value for this warp course is read out and utilized for controlling thread provision. An arrangement for the control of the thread provision means of a warp knitting machine (1) will comprise (a) a computer (6), a table storage means (13), (b) a program storage means (11) for a programmed recognition routine, (c) an evaluation device (12) for reading out a table (100 through 107 ), and (d) a control device (5) which by use of the thread …
