Product Introduction
Paper Slitting and Rewinding Equipment converts wide paper parent rolls into narrower finished rolls through unwinding, web guiding, slitting and rewinding. The machine range covers different paper weights, roll dimensions and finished widths, with the working configuration determined by the material and required roll specification.
Paper Materials
Processes kraft paper for packaging, wrapping, bags and other roll converting applications.
Handles printing grades requiring defined widths, stable web movement and consistent rewinding.
Processes paper label materials where slit width, edge condition and finished-roll dimensions require close control.
Typical Applications
Packaging Converting
Produces narrow paper rolls for packaging, wrapping and bag-making processes.
Printing Operations
Converts parent rolls into production widths specified for printing applications.
Industrial Paper
Prepares paper rolls for processes requiring repeatable widths and defined finished-roll dimensions.
Working Process
Unwinding
The parent roll is loaded onto the unwinding section and fed through the machine under controlled web tension.
Slitting
The paper web passes through the knife section, where the parent web is divided into the specified finished widths.
Rewinding
Separated webs are wound onto individual cores according to the required finished-roll diameter and winding conditions.

Selection Criteria
Working Width
The working width is selected from the maximum parent-roll width, required finished widths and available trim arrangement.
Paper GSM
Paper weight affects tension settings, knife selection and rewinding conditions. The machine range should correspond to the grades processed.
Finished Width
The minimum finished width determines the knife arrangement, lane layout and usable shaft configuration.
Roll Diameter
Parent-roll diameter determines unwinding capacity, while finished-roll diameter affects rewinding and unloading requirements.
Rewinding Control
Web Tension
Tension settings are matched to paper weight and thickness to maintain stable web movement during rewinding.
Roll Hardness
Winding conditions are adjusted according to paper grade, finished width, core diameter and target roll diameter.
Core Position
Core spacing follows the finished-width layout so that each slit web is wound on its specified core.
Slitting Configuration
Razor Slitting
Used for paper applications requiring narrow slit widths and a compact knife arrangement.
Circular Knife Slitting
Used where the paper grade, thickness and finished-width combination calls for a circular knife setup.
Production Considerations
Changeover
Knife position, core spacing and finished-width settings determine the preparation required between production orders.
Trim Layout
Finished-width planning determines knife placement across the parent web and helps make efficient use of available material width.
Roll Handling
Finished-roll diameter, width and weight are considered when defining shaft arrangement and unloading requirements.
Manufacturing & Quality Control
Machine frames and mechanical components pass through cutting, fabrication, machining and assembly operations before final testing.
Web transport, mechanical movement, slitting operation and rewinding functions are checked during machine assembly and testing.
The final setup is established from actual paper data, parent-roll dimensions, finished widths and winding requirements.
Why Choose This Configuration
Paper Processing
The machine arrangement is based on paper GSM, thickness, roll dimensions and finished-roll requirements.
Production Flexibility
Working width, knife arrangement, core diameter and winding settings can be selected for different paper specifications.
Specification-Based Design
The equipment is configured from defined production data, allowing the technical setup to correspond to the intended paper-converting process.
Technical Information Required
Material
Paper type, GSM, thickness, coating and surface characteristics.
Roll Data
Parent-roll width, outer diameter, core diameter and maximum roll weight.
Finished Roll
Required slit widths, number of lanes, finished diameter and core specification.
Production Target
Required running speed, production volume, roll length and winding arrangement.
FAQ
Q: What paper can this equipment process?
A: The equipment can be configured for kraft paper, printing paper, label stock and other roll-based paper materials according to their weight, thickness and roll requirements.
Q: How is the machine configuration selected?
A: The main selection factors are working width, paper GSM, parent-roll diameter, finished-roll diameter, slit width, core size and production speed.
Q: Can several finished widths be produced?
A: Yes. Knife positioning and shaft configuration can be arranged for multiple finished widths within the specified working range.
Q: What information is required for a technical quotation?
A: Provide paper type, GSM, thickness, parent-roll width and diameter, core diameter, finished widths, finished-roll diameter and target speed.
Q: Can the machine be configured for different paper specifications?
A: Yes. The working width, slitting arrangement, core layout and rewinding settings can be matched to defined material and finished-roll requirements.
