The CQA819PD fully automatic PP strap winder produces finished packages with a maximum outer diameter of 500 mm. Together with a standard 203 mm core diameter, each coil holds significantly more strap length, effectively reducing the frequency of coil changes for end users. Large-diameter coils are especially beneficial for automatic strapping lines, greatly reducing downtime for strap replacement and improving packaging efficiency. The machine's integrated transport system automatically removes the heavy 500 mm coil and feeds a new tube from the magazine - no manual lifting required. Winding such large coils demands high precision in tension control and layering, and the CQA819PD's dancer constant tension system and electronic 2/3-point layering ensure uniform density and neat end faces from the inner core to the outer layer.
Dancer constant tension, uniform from core to outer layer
Key Features
500 mm large OD - Holds 30-60% more length than common 300-400 mm coils.
Fewer downstream change-overs - Automatic strapping machines run longer without stopping.
203 mm standard core - Compatible with most winding cores and pay-off stands.
Automatic unloading - 500 mm coils weigh tens of kilograms, handled without manual lifting.
Constant tension throughout - Stable tension even at large diameter, avoiding loose inner layers.
Precision layering for neat ends - Electronic 2/3-point layering keeps 500 mm coil ends flat, no edge collapse.
Automatic core feeding - Sleeve magazine supplies new 203 mm tubes for non-stop change-over.
Frequently Asked Questions
Q1: How many meters of strap does a 500 mm OD coil contain?
It depends on strap thickness and width. For a typical 12 mm wide, 0.6 mm thick PP strap, a 500 mm OD coil with 203 mm ID contains about 1000-1200 meters. Precise control can be achieved via the weight measurement mode.
Q2: Is a 500 mm coil too heavy for automatic unloading?
The automatic unloading mechanism is designed to handle over 50 kg, and the conveyor belt has an anti-slip texture for smooth removal. Simply pick up the coil from the deposit area using a forklift or lift table.
Q3: Do I need to reduce winding speed when making 500 mm coils?
No. The maximum mandrel rotation speed is 500 r/min. As the diameter grows, the winder reduces rotation speed to maintain constant linear speed (up to 300 m/min). The entire winding process can be done at full line speed.
Q4: What special layering requirements does a 500 mm coil have?
On large coils, each layer contains much longer strap length. Uneven layering can cause edge build-up or depression. The CQA819PD's electronic 2/3-point layering dynamically adjusts the traverse pitch according to the current coil diameter, ensuring a flat end face at all times.
Q5: Can I produce smaller coils (e.g., 300 mm) on the same machine?
Yes. Simply set the target package diameter to 300 mm on the touchscreen. The machine will automatically unload when that value is reached. No mechanical adjustment is needed - the same machine can produce both large 500 mm coils and smaller coils.
