Production by Lots with Ejection after Each Lot

The design systems M1plus or Create do not support directly the production of lot sizes with ejection of each lot and starting the next lot using the comb. You have to do some modifications of the pattern to enable such a production with a correct counting of the pieces by the PPS.

The design system supports the start of knitting with comb, knitting n pieces and casting-off the very last piece. Using the RS17 prevents the casting-off of each piece separately. First, create your pattern this way.

How to modify the Sintral code in order to produce certain lot sizes with casting-off each lot separately

  1. A pattern with RS17 for comb and casting-off is created.
    RS10 contains the lot size
    RS17 controls knitting with comb and casting-off.
    #80 is used to count the pieces of the lot. #80<1 of Sintral means to reduce #80 by 1.
    #100 is the machine's countdown total piece counter, which can only be read.

    These code changes must be done:
    Insert this line before the START and adjust the line number to your code.

    20 IF RS10=0 RS10=50

    20 If RS10 is not configured in the setup (value is 0), specify a default lot size (50 in this example).

    Change the line with the set RS17 before the last >> stroke before END or at the end of the M1-SINTRAL function. With it, watch the C (what was entered here by M1plus needs to be commented out at the end):

    808 F:LOTCTRL; C RS17=1 IF#100=1 RS17=0

    808 Controls the production of a lot

    Insert the LOTCTRL function at the end of the Sintral where it fits in:

    960 FBEG:LOTCTRL;
    965 IF #80<1 #80=RS10+1
    970 RS17=1 #80<1
    975 IF #80=1 RS17=0 #80=RS10+1 MS PRINT/     BOX IS FULL. PLEASE PULL ENGAGING ROD /
    980 IF #100=1 RS17=0 #80=0
    985 FEND

    960 Function for controlling production by lots

    965 Initialization for down counter #80 after the very first part. RS10 should include the lot size

    970 Prevent cast-off and count down parts of the lot

    975 After the last part of the lot, enable the cast-off and set counter #80 to the lot size + 1 so that #80 is set to 1 for the last part.

    980 When the last piece of all pieces has been knitted, discard, restart, enable comb and set #80=0, so that if the last lot is incomplete, #80 is set again when restarting.

    985 End of control function LOTCTRL, return
  1. While the reported to PPS piece counter continuously increases, thus being correctly recorded and allowing the total quantity to be specified in the XML order, the production is divided into lot sizes and each lot is ejected. You can specify the quantity of the lot as desired.
