Страница: 4 / 56

1. Brief introduction
Model GC6-6 and GC6-7 medium and heavy
duty lockstitch sewing machine both are constructed
with the mechanisms of single needle, link thread
take-up with needle bearing, precise spiral bevel gear
transmition, big rotating hook with double thread
capacityand forward or reverse sewing. They have
the same advantages of small momentof torsion,
low noise, feeding smoothly even from sewing
single layer to the lap seams with equability of
stitch length, beautiful flat stitches in appearance.
They are widely used in the factories of suitcase,
bag, leather goods, sofa, tarpaulin, cushion,cloth,

The main differences between machines of Model
GC6-6 and Model GC6-7 are as follows:
The feed mechanism of model GC6-6 is constructed
by the top feed of walking presser foot and bottom feed
of feed dog.
It can be adjusted to achieve the synchronization
of top and bottom feed , to eliminate the slippage
between top and bottom layers when sewing loose
bulge and slippery materials, also, the top feed can
be adjusted in differential with the bottom feed for
sewing pleat.
Whereas on machine Model GC6-7, the synchr-
onized top feed of walking presser foot, needle feed
and bottom feed of feed dog forming the unison feed,
which the slippage between material layers could be
eliminated absolutely.So that the elastic and slippery
materials can be sewn successfully. Most of this
machine is the top feed presser foot nearing needle,
therefore the cording, lap seaming and folding all
are convenient.
