As the gathering factors of tapes or trouser cloths are likely to vary, we can select 5 different gathering factors.
To adjust transmission ratio of the metering device to the main motor we recommend to proceed as follows:
Set parameter 875 to 15
Set parameter 950 to 0
Now sew tape desired onto the respective trouser cloth. If the heel tape is too short use key
“L” in
programming mode (level B) to select a lower value of P875 . Factor in parameter P875 has been
selected correctly, if the tape has been attached smooth and evenly without any loops between presser
foot and metering device.
Now you are ready to insert the factors in parameters 951, 952 and 954. The higher the factor the shorter the
heel tape length.
Press key “P” to select a gathering factor R0 to R4 in the AUTOMATIC MODE.
