CTE CTE-U

Flat Suction Auto Thread Chain Cutter Device (with Sensor-controlled Energy-saving Device )

Sensor checks the fabric edge. It saves the energy consuming of air compressor system and also
saves thread consuming.
1. Vertical suction trimming is suitable for sewing the light fabric like under-wear or irregular knitwear,
to improve the efficiency.
2. The design of the suction inlet of the trimmer makes the trimming faster.
3. For those special fabrics such as mesh fabric, mercerized cotton etc, the stitches are easily
accomplished as well as the trimming by the professional computer controlled without mistaketrimming.
4. Functions with auto stop sewing after trimming and with no fabric can save the stitches.
5. VTA trimmer is controlled by air cylinder, which reduces the blade stroke times and extends the
durability.

ECA

Pneumatic Type Tape / Thread Cutter ( With Auto / Manual Switch Function)


ECB

Solenoid Type Tape / Thread Cutter ( With Auto / Manual Switch Function )

Brand new sensor upgrades the performance. ECA is pneumatic type, and ECB is electric type,compatible with air suction slot, which makes the operation more smoothly.

  1.  Manual, semi-auto and fully-auto operation mode, attached the switch keys, and could be adjusted by the panel.
  2.  Mistake-proof protection device: One sensor equipped near the trimmer. If the sensor is blocked, the trimmer is deactivated effectively for avoiding from cutting the fabric.
  3. Manual trimming compensation stitch key: If the thread is not cut due to the operation, it can be done by the key.
  4.  Under the manual mode, it could be fully backward pedaled to cut the thread.
  5. For those special fabrics such as mesh fabric, mercerized cotton etc, the stitches are easily accomplished as well as the trimming by the professional computer controlled without mistaketrimming.
