80700 Series FIBC Sewing Machine-Hebei Longsew|Heavy-Duty Chain Stitch,Double Needle

Product Overview and Key Features

The 80700 series sewing machine is a cornerstone of the FIBC bag manufacturing industry, designed to handle the rigorous demands of heavy-duty fabric production. It is available in three primary configurations: 80700C (Single Needle), 80700CD (Double Needle), and 80700CD4H (Advanced Double Needle with Additional Features). Each model offers customizable options to suit specific production needs.

Configurations and Customization Options

• 80700C: A single-needle model with basic functionality, available with either a clutch motor or a servo motor for enhanced control.
• 80700CD: A double-needle variant offering parallel chain stitching, also compatible with clutch or servo motors.
• 80700CD4H: The most advanced version, featuring a pneumatic foot lift system, hot cutter system, needle position fixation, and cooling mechanisms. This model requires a servo motor for optimal performance.

Optional functions include pneumatic foot lift systems, hot cutter systems, spout-type table tops and stands, and servo or clutch motors. These features ensure adaptability for diverse production environments, from standard FIBC bag manufacturing to specialized applications requiring precision and automation.
