Needle cooler device

OT (One-touch) Presser

Soft presser

Cassette presser

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.

Play prevention work clamp	This work clamp prevents any play from occurring in the
	clamp.
Thread wiper, side type	Wipes the upper thread away to the side when an inner
	clamping device is being used.
Air wipper device	The thread wiper is driven by a pneumatic cylinder.
2-step thread tension device	Allows the upper thread tension to be switched between
	two settings at any position desired by using the
	programmer.
Thread take-up device	After the thread is trimmed, an upper thread trailing length,
	which is handy when sewing light materials where normal
	trailing thread lengths can often lead to the thread pulling
	out. (311F series: Solenoid type, 326F: Pneumatic type)
Automatic ejector	When the reflective plate of the cassette is detected by the
	sensor, the cassette is held automatically by a pneumatic
	cylinder. In addition, the programs can be set so that the
	cassette is ejected automatically.
