Automatic Label Roll Winding And Counting Machine
Reliable Operational Workflow
The Harsiddh Automatic Label Roll Winding and Counting Machine serves as a vital bridge in the packaging line. The operator places the master label roll on the unwinder; as the machine winds the labels onto the secondary core, an optical sensor counts each unit.
If a coding system is integrated, the machine provides a stable, flat surface for the printhead to apply data with high legibility. This process allows manufacturers to prepare labeled rolls offline, significantly reducing downtime on the primary labeling line.

Frequently Asked Questions
How does the machine ensure accurate counting of different label types?
The Harsiddh machine utilizes high-precision photoelectric sensors to detect the gaps between labels.
Standard Labels: Uses an infrared "U-shaped" sensor to detect the opacity difference between the label and the backing paper.
Transparent Labels: Can be fitted with an optional ultrasonic sensor that detects the thickness change, ensuring 100% accuracy even for "clear-on-clear" labels where standard light sensors might fail.
Can the machine detect missing labels on the roll?
Yes. Advanced models can be equipped with a Missing Label Detection System. If the sensor detects a gap where a label should be (due to a printing or die-cutting error), the machine can be programmed to automatically stop at the exact location of the error. This allows the operator to fix the roll manually, ensuring that only perfect rolls are delivered to the high-speed automatic labeling machines.
How does the machine handle different core sizes and roll widths?
The machine is built for maximum versatility to handle various industry standards:
Core Sizes: It typically features interchangeable or expandable mandrels to accommodate 25mm, 38mm, and 76mm (1", 1.5", and 3") internal core diameters.
Tension Control: It uses an adjustable electromagnetic brake or mechanical tensioner to ensure the labels are rewound tightly and neatly without stretching or wrinkling the backing paper.
What is the operating speed and control mechanism?
The machine is designed for high-speed efficiency:
Output: It can achieve rewinding speeds of up to 80 to 150 meters per minute, depending on label size.
PLC Interface: Through the Digital Control Panel, operators can pre-set a specific count (e.g., 500 or 1000 labels). Once the machine reaches the target count, it decelerates and stops automatically, preventing over-runs and ensuring batch consistency.
