In the packaging industry, corrugated cardboard is a ubiquitous material used to protect and transport goods. Corrugated rotary machines play a crucial role in the production of corrugated cardboard by shaping and forming the paperboard into its characteristic fluted structure. With various types of corrugated rotary machines available, choosing the most suitable one for a specific application requires careful consideration.

Factors to Consider

When selecting a corrugated rotary machine, several key factors to consider include:

Type of Corrugation

The type of corrugation refers to the shape and size of the flutes formed in the cardboard. Common types include:

– A-flute: Wide, shallow flutes for heavy-duty packaging

– B-flute: Medium-sized flutes for general packaging

– C-flute: Narrow, deep flutes for lightweight packaging

Each type of flute has its own strengths and weaknesses, so it is important to choose the one that best meets the requirements of the intended application.

Machine Speed

The speed of the machine is measured in meters per minute (m/min) and determines the output capacity. Higher speeds are suitable for high-volume production, while slower speeds may be preferred for more precise or intricate work.

Material Handling

The machine’s material handling capabilities refer to how it feeds and discharges the paperboard. Common options include:

– Automatic: Machines that automatically feed and discharge paperboard using conveyors for high-speed operations

– Manual: Machines that require manual loading and unloading for smaller-scale production or customized work

Scoring and Creasing

Scoring and creasing are essential processes in corrugated board production to facilitate folding and assembly. Some rotary machines are equipped with additional features for scoring and creasing, while others may require separate equipment.


The level of automation in the machine affects its ease of operation and overall efficiency. Fully automated machines can operate with minimal human intervention, while semi-automated or manual machines require more operator involvement.

Comparison of Rotary Machine Types

Based on these factors, there are several types of corrugated rotary machines to choose from:

Single Facers

Single facers form the first layer of corrugated cardboard, consisting of a corrugated medium and a single linerboard. They are suitable for low-volume production or for producing corrugated board for other products, such as honeycomb panels.

Double Facers

Double facers form two layers of corrugated cardboard, consisting of two linerboards and a corrugated medium. They offer higher production speeds and are commonly used for the production of corrugated cardboard used in packaging.

Folder Gluers

Folder gluers combine multiple layers of corrugated cardboard into a finished box by folding, gluing, and sealing it. They are used in high-volume production lines to automate the box-making process.

Corrugator-Folder Gluers

Corrugator-folder gluers combine the functionalities of a double facer and a folder gluer into a single machine. They are highly efficient and space-saving for high-speed production of finished corrugated boxes.


Choosing the most suitable corrugated rotary machine depends on the specific requirements of the application. By considering the type of corrugation, machine speed, material handling capabilities, scoring and creasing needs, and desired level of automation, manufacturers can make an informed decision to optimize their corrugated cardboard production operations.
