High-speed platform overlock sewing machine for mattress sewing machinery

Platform overlock sewing machine is mainly used for sewing between mattress fabric and side circumference edge material, also can be used for sewing another upholstered mattress, sleeping bags, and tent.

Traditional platform overlock sewing machines are usually modified with ordinary locking or chain machines, which are limited by the structural characteristics of the machine head itself, so the maximum speed does not exceed 3500r/min and the maximum sewing thickness does not exceed 50mm, while the stitch distance is small when sewing thick materials due to the small tooth shape of the fabric feeder and the insufficient grip on the fabric, which is usually around 4.5mm at the maximum.

Therefore, some users asked whether it was possible to develop an overlock machine with higher speed and better ability to eat thicker material. As a result, the presser foot and the fabric feeding tooth structure were improved, the cutter and other parts were removed, and the edge band release and guide device were added. The presser foot of the machine head was lifted high to make the placement of thick materials easier, and the tooth pitch and height of the feeding teeth were increased to make the material more powerful, and the speed, stitch pitch, and thickness eating ability were greatly improved compared with the traditional machine. At the same time, the feeding teeth have reserved space for inlaying the rope strip, which is convenient for customers to add filler when wrapping the edge and make the sewing effect more full.
