Product Overview
Turret Surface-Drive Slitting Equipment converts wide parent rolls into multiple finished rolls through unwinding, web guiding, longitudinal slitting and turret rewinding. The surface-drive system transfers winding force through controlled contact with the finished roll, while the turret mechanism manages the winding positions and automatic roll change.
The machine configuration is matched to material type, web thickness, working width, parent-roll diameter, finished-roll diameter, core size, slit width and required line speed.
Surface-Drive Turret Winding
The winding drum maintains controlled contact with the finished roll during winding. This keeps the winding pressure stable as the roll diameter increases.
Two winding positions rotate through the production cycle. The prepared core moves into the winding position while the completed roll proceeds to the discharge stage.
Surface-drive force and web tension are coordinated to establish the required roll hardness for different materials and finished-roll sizes.
Key Product Advantages
Stable Winding
Controlled contact between the drum and finished roll supports consistent roll formation across the winding cycle.
Automatic Changeover
The turret system coordinates core positioning, winding transfer and completed-roll removal within the automatic change sequence.
Format Flexibility
Slit width, core diameter and finished-roll diameter can be configured around the required converting format.
Controlled Web Handling
Unwinding, guiding, slitting and rewinding are synchronized to maintain stable material movement through the machine.
Slitting Section
Knife Setting
Knife positions are arranged according to the required slit pattern, material thickness and finished-roll width.
Edge Quality
Knife condition, blade alignment and web tension are controlled together to maintain clean longitudinal edges.
Slit Layout
Multiple finished-roll widths can be arranged across the working width according to the required roll combination.
Web Tension Control
Unwinding
Unwind tension is regulated as parent-roll diameter decreases, maintaining controlled material feed into the slitting section.
Web Guiding
The guiding system corrects lateral web movement before slitting and rewinding to maintain roll alignment.
Rewinding
Winding tension is adjusted according to material thickness, elasticity, friction and finished-roll diameter.
Typical Materials
Plastic Films
The machine can process flexible films requiring controlled tension, accurate slit positioning and stable roll winding.
Paper Materials
Paper webs can be processed with winding conditions selected according to thickness, stiffness and required roll density.
Metallized Films and Foils
Tension, knife settings and winding pressure can be matched to sensitive web materials to maintain stable processing conditions.
Typical Applications
Packaging Conversion
Wide packaging webs can be slit into narrower rolls for printing, bag making, lamination and subsequent converting operations.
Label Material
The slitting section supports narrow-roll production where slit positioning, edge condition and roll alignment are key process requirements.
Industrial Roll Processing
Wide industrial webs can be converted into specified roll widths and diameters for downstream processing and application.

Configuration Selection
Material Data
Material type, thickness, tensile strength, elasticity and surface friction determine the required tension, knife arrangement and winding conditions.
Roll Data
Parent-roll width and diameter define unwind capacity. Finished-roll diameter and core size determine the winding configuration and turret requirements.
Output Data
Required line speed, finished-roll width, roll weight and changeover frequency should be confirmed before final machine configuration.
Quality Control Points
Slitting Accuracy
Knife alignment and slit-width settings are checked against the specified finished-roll dimensions.
Roll Hardness
Winding pressure and web tension are adjusted according to material thickness, roll diameter and required finished-roll density.
Roll Alignment
Core positioning, web guiding and winding conditions are coordinated to maintain straight roll edges and consistent roll geometry.
FAQ
Q: What materials can be processed?
A: The equipment can be configured for plastic films, laminated webs, paper, metallized films, aluminium foil and other roll materials according to their processing characteristics.
Q: What does surface-drive winding control?
A: The winding drum applies controlled contact force to the finished roll and works with web tension to maintain the required winding condition as roll diameter increases.
Q: Can several slit widths be produced in one run?
A: Yes. The knife arrangement can be set for multiple finished-roll widths across the available working width.
Q: How is finished-roll diameter selected?
A: Finished-roll diameter is determined by material thickness, core diameter, roll weight, downstream handling requirements and the required winding format.
Q: What information is needed before configuration?
A: Material type and thickness, parent-roll width and diameter, target slit widths, core diameter, finished-roll diameter and required line speed provide the main configuration data.
Q: Can the machine connect with upstream or downstream equipment?
A: Control signals, speed references and web-handling requirements can be specified according to the operating conditions of connected production equipment.
