Waste-edge rewinder

Product positioning and objectives

• Used to wind and reclaim edge trim generated after printing, slitting, or trimming, by applying closed-loop tension control for winding and recovery. This improves material utilization, reduces edge trim costs, and facilitates subsequent recycling and secondary processing.

Applicable materials and scenarios

• Films, packaging materials, paper-based materials, and edge waste generated by various process lines (slitting machines, printers, extruders, etc.).

• Compatible with a wide range of widths and thicknesses; easily interfaces with existing production lines.

Main features

• Efficient recovery and compact design: improves material utilization, winds tightly and flatly, and reduces roll deformation and loose winding.

• Closed-loop tension control: automatic, stable tension control ensuring consistent winding quality.

• Easy system integration: interfaces with slitting, printing, extrusion equipment; short line-change times and low integration costs.

• Automation and digitization: sensors, PLC/HMI, etc. enable automated control; production data traceable and supports remote diagnostics.

• Safety and reliability: comprehensive guarding, emergency stop, and interlock designs to enhance operator safety.

• Energy-efficient and low-noise, easy maintenance: compact structure, small footprint, quiet operation, low maintenance costs.

• Scalability: supports multi-machine networking, data export, remote diagnostics; easy to upgrade and expand.

Structure composition (typical)

• Feeding and pretreatment unit (sliding frame/guide rollers, tension sensors, etc.)

• Closed-loop tension control system (sensors, servo/stepper drives, control cabinet)

• Rewinding unit (rewind rolls, tension balancing mechanism, surface protection components)

• Edge trim cutting and waste handling unit (edge trimming, waste separation and collection devices, waste bin or waste discharge interface)

• Control and human-machine interface (PLC/HMI touchscreen, Ethernet communication, sensor interfaces)

• Safety protection and emergency stop devices (protective covers, interlocks, emergency stop buttons, warning systems)

• Control system: PLC/HMI, supports fieldbus communication, data collection and export

• Air supply requirements: compressed air supply (as per model configuration)

• Dimensions and weight: customized per model; on-site space requirements to be confirmed

Control and software

• Touchscreen HMI for parameter setting, operation status, alarm logs, line synchronization, etc.

• Data collection and traceability; supports export to CSV/Excel

• Remote diagnosis and maintenance support (optional)

Safety and standards

• Compliant with relevant industrial safety standards (e.g., CE/UL, configured per region/customer)

• Mechanical guarding, emergency stop, interlocks, and safety interlocks

Installation and after-sales
