Differential feed

There are two feed dogs one front (C) and one rear (D). The two feed dogs move in-
dependently and the distance each feed dog travels during one complete movement
can be adjusted. The differential feed prevents fluting or waving in knitted or stretch
fabrics and movements between the layers of fabric. It also ensures pucker-free
seams in smooth fabric such as nylon or closely woven fabric.
Perfectly flat seams in knits or stretch fabrics.
The distance travelled by the front feed dog should be greater than that of the rear
feed dog. The front feed dog, therefore, feeds an amount of fabric which the rear
feed dog can take up behind the needle without stretching the fabric. (E)
Pucker - free seams in nylon or closely woven fabrics.
The distance travelled by the rear feed dog should be greater than that of the front
feed dog. The front feed dog, therefore, holds the fabric back so that the rear feed
dog can take it up behind the needle without any puckering. (F)
Adjusting the differential feed
The differential feed can be adjusted by simply turning the differential feed adjust-
ment dial in the direction desired. Always make a trial run. The differential feed is
infinitely variable and can be adjusted while sewing.
调节差动送布
本机器有前齿（C）和后齿（D）共 2 组送布牙。这 2 组送布牙均可独立运作，同
时当一个送布牙完成一个完整的运动轨迹时，另一个送布牙开始运作。差动送布
可防止针织或弹性面料间的偏差或移动以及多层面料间的送布运动。同时还可确
保平滑面料如尼龙或是无缝面料的缝制无误。
针织或弹性面料的平整接缝
前送布牙移动的距离应大于后送布牙。由此，前送布牙在输送一定的送布量时，

位于机针后方的后送布牙可有效防止弹性面料损伤。 （E）

通过后送布牙移动的距离应大于前送布牙。由此，前送布牙可保持住面料，而位
于机针后方的后送布牙可有效防止起皱。 （F）

调整差动送布
差动送布可以按照所期望的通过简单地旋转差动送布调节旋钮来进行调整。请务
必先进行试缝。该差动送布可无级变速并可在缝制中微调。
