Six Independent Drop-Down Winding Machines with Servo Traversing (0-300 m/min)
Product Introduction
Winding is the final process in PP strapping production, directly determining the appearance quality of finished rolls and customer satisfaction. This production line is equipped with 6 independent fully automatic drop-down winding machines, each corresponding to one strapping strand.
Each winder is driven by an independent servo motor (1.5KW) and a servo traversing system (0.4KW), with a winding speed of up to 300 m/min. Independent control allows separate setting of winding tension and speed for each strand, perfectly accommodating minor variations that may occur in multi-channel production.
The drop-down unloading design allows finished rolls to automatically drop off, making operation convenient and efficient. The servo-driven traversing system ensures uniform, tight arrangement of the tape on the paper core, resulting in neat rolls with flat end faces, without loose or overlapping layers.

Customer Q&A
Q: Why six independent winders instead of one multi-spindle winder?
A: Independent winders allow each strand to have separate tension and speed control. Even if the six strands have minor thickness or elasticity differences, each can be adjusted individually, avoiding uneven tension caused by a shared drive. Also, if one strand breaks or requires a roll change, the other five are unaffected, reducing downtime losses.
Q: What are the advantages of servo traversing over mechanical traversing?
A: Servo traversing offers fast response, high precision, and programmable traverse width and pitch to suit different tape widths and winding speeds. It produces neater rolls, especially suitable for high-speed winding (300 m/min) and precision winding requirements.
Q: How does drop-down unloading work? Is manual assistance needed?
A: When the set length is reached, the winding shaft stops automatically, and the drop-down mechanism flips the finished roll downward, allowing it to slide onto a conveyor or collection rack. The operator only needs to place an empty paper core and start the next roll - semi-automatic assistance is sufficient.
