The SHBM-JQ surface curling and slitting machine is a specialized narrow-web slitter rewinder designed for ultra-narrow strip processing, with a minimum slitting width of just 5mm. Featuring full servo drive control (1 main servo 2 rewinding servos), Siemens PLC intelligent system, and interchangeable circular/straight blade sets, it delivers precision slitting at speeds up to 400 m/min for offset paper, coated paper, aluminum foil, PVC film, and insulation materials across printing, packaging, and converting industries.

Core Performance and Features

Siemens PLC Intelligent Control System

Equipped with Siemens PLC for full automated operation, including automatic meter counting, residual material detection with alarm and shutdown, and automatic stop at preset length. Ensures stable, reliable, and hands-free production runs.

Full Servo Drive Configuration

The entire machine adopts full servo drive: one servo motor for the main unit and two servo motors for rewinding. This triple-servo architecture delivers precise tension control, rapid response, and consistent rewinding quality across varying material types and thicknesses.

Ultra-Narrow Strip Slitting (Minimum 5mm)

Capable of slitting products down to 5mm width, making it the ideal solution for processing narrow and thin materials that conventional slitters cannot handle. The surface curling winding structure ensures tight, uniform narrow rolls.

Interchangeable Circular and Straight Blade System

Equipped with both circular and straight slitting blades. Supports quick-change interchangeable cutting for paper and film materials, realizing true multi-purpose capability in a single machine without blade-system replacement downtime.

High-Sensitivity Automatic Web Guide

Fitted with a high-sensitivity EPC (edge position control) automatic web guide device achieving /-0.1mm correction accuracy, effectively guaranteeing slitting precision across all material types and operating speeds.

Flexible Unwinding and Feeding Options

Supports both split and integrated automatic feeding configurations. Shafted and shaftless unwinding modes are available for flexible selection, meeting diverse application requirements from lightweight films to heavier paper rolls.

Adjustable Air Shaft Configuration

3-inch to 6-inch air shafts are optional for unwinding (3-inch as standard), with corresponding 3-inch to 6-inch rewinding shafts (3-inch air shaft standard). Custom core sizes are available upon request to match specific roll requirements.

High-Speed Production Capability

Maximum running speed reaches 400 m/min, delivering high processing efficiency for both narrow strip and standard-width production. The servo-driven system maintains precision even at maximum operating speed.

Structural Design and Advantages

Surface Curling Winding Architecture

The surface winding (curling) design applies consistent contact pressure across the roll surface during rewinding, producing tightly wound, uniform narrow strips. This is particularly critical for ultra-narrow widths where center-winding tension can cause telescoping or edge damage.

Trip Servo Precision Drive

One main servo motor drives the slitting section while two independent rewinding servos control tension on each rewind shaft. This independent dual-shaft servo control enables different tension settings per material type simultaneously.

Quick-Change Blade Assembly

The interchangeable circular and straight knife set allows rapid switching between shear-cut mode (circular blades for paper/cardboard) and razor-cut mode (straight blades for film/foil), maximizing machine utilization across mixed material jobs.

Customizable Machine Dimensions

Overall machine dimensions can be customized according to customers' on-site space conditions, ensuring the slitter fits within existing production layouts without compromising performance or accessibility.

Frequently Asked Questions

What is the minimum slitting width of the SHBM-JQ surface slitter?

The minimum slitting width is 5mm, making it ideal for ultra-narrow strip production. This capability sets it apart from standard slitters that typically cannot reliably process strips below 10-15mm width.

What is the maximum running speed?

The maximum operating speed is 400 m/min across all four width models (1100/1300/1600/1800mm). The full servo drive system maintains slitting precision even at maximum speed.

What is the EPC correction accuracy?

The high-sensitivity automatic web guide achieves /-0.1mm correction accuracy, ensuring consistent edge quality and precise strip dimensions across all material types and operating speeds.

What unwinding modes are available?

The machine supports both split and integrated automatic feeding configurations, with shafted and shaftless unwinding modes available for flexible selection based on material type, roll weight, and production requirements.

Can the machine handle both paper and film materials?

Yes. The interchangeable circular and straight blade system allows quick switching between shear-cut mode for paper/cardboard and razor-cut mode for film/foil, enabling true multi-material capability in a single machine.
