Feed amount on the operation consists of the three
kinds of feed amounts, bottom feed amount (pitch),
main feed amount (pitch + shirring amount) and
auxiliary feed amount (pitch + shirring shirring
amount for auxiliary feed).
In case of A, when pitch (S04) is set to 2.0, bottom
feed belt
1
moves 2.0 mm per rotation of the sewing
machine (1 stitch).
In case of B, when shirring amount is set to 3, main
feed belt
2
moves 2.3 mm per rotation of the sewing
machine ( 1 stitch).
This means that set value “1” of shirring amount (main
feed) is in steps of 0.1 mm and when the set value is
converted to mm, 3 x 0.1 = 0.3 mm is calculated. This
value is added to pitch (bottom feed) and the total value
becomes the moving amount of the main feed belt.
Main feed amount = pitch + shirring amount
2.3 mm = 2.0 mm + 0.3 mm
In case of C, when shirring amount for auxiliary feed is
set to 2, auxiliary feed belt
3
moves 2.5 mm per
rotation of the sewing machine (1 stitch).
This means that set value “1” of shirring amount for
auxiliary feed (auxiliary feed) is in steps of 0.1 mm
and when the set value is converted to mm, 2 x 0.1 =
0.2 mm is calculated. This value is added to the main
feed amount and the total value becomes the moving
amount of the auxiliary belt.
Auxiliary feed amount = main feed shirring
amount for auxiliary feed
2.5 mm = 2.3 mm + 0.2 mm
The explanation is given for the feed amount of the sewing machine.
