Available as rotary type or fiber type, stops sewing when a thread
breakage is detected and warns the operator.
This is a pneumatic-type needle cooler which prevents the thread
breaking due to heat. It is particularly useful when sewing thicker
materials at high sewing speeds.
Use according to particular sewing needs in order to provide an
even clamping force.
At the first stage, the work clamp applies only a spring force so
that the material can be positioned. Then at the second stage, air
pressure provides a full clamping force.
This allows the operator to hold two clamps so that the
preparation for the next operation can be carried out while sewing
is in progress.
Overlapping operations are thus possible, which can greatly boost
productivity.
This work clamp prevents any play from occurring in the clamp.
Wipes the upper thread away to the side when an inner clamping
device is being used.
The thread wiper is driven by a pneumatic cylinder.
Allows the upper thread tension to be switched between two
settings at any position desired by using the programmer.
