what is coil slitting machine?

A coil slitting machine, also known as a slitter rewinder, is a piece of industrial equipment used to cut wide coils of material into narrower strips. It is commonly used in various industries, including metal processing, paper production, plastic manufacturing, and textile production.

The primary function of a coil slitting machine is to take a large coil, often referred to as a master coil, and unwind it while simultaneously cutting it into smaller coils or strips of specific widths. The machine typically consists of several components, including a decoiler, slitter heads or knives, tensioning systems, and a rewinder.

Here’s a basic overview of the coil slitting process:

  1. Decoiling: The machine begins by unwinding the master coil, which is mounted on a decoiler. The coil is unwound and fed into the slitting section of the machine.
  2. Slitting: The slitting section consists of multiple slitter heads or circular knives that are positioned to cut the wide coil into narrower strips. The number of slitter heads and their arrangement can vary depending on the desired strip width and the material being processed.
  3. Tensioning: Tensioning systems are used to ensure proper tension is maintained throughout the slitting process. This helps prevent material defects and ensures accurate cutting.
  4. Rewinding: Once the coil has been slit into narrower strips, the rewinding section of the machine winds the strips onto separate rewinder shafts or cores. The rewinder can also be equipped with various features, such as edge guides or inspection systems, to ensure the quality of the finished strips.
  5. Optional Features: Advanced coil slitting machines may include additional features such as automatic positioning systems, laser measurement systems for precise strip width control, and automated control systems for enhanced productivity and efficiency.

Coil slitting machines are highly versatile and can handle a wide range of materials, including metal coils (such as steel, aluminum, and copper), paper rolls, plastic films, and textile fabrics. They play a crucial role in the manufacturing process by providing narrower and more manageable strips or coils that can be further processed into finished products or used in downstream production operations.

function of metal slitting machine

A metal slitting machine is used in various industries, such as steel processing, metalworking, and fabrication, to cut large coils of metal into narrower strips or slits of desired widths. The primary function of a metal slitting machine is to convert wide coils of metal into narrower strips that are more manageable for further processing or distribution. Here are some key functions of a metal slitting machine:

  1. Slitting: The main function of the machine is to cut the metal coil into multiple narrower strips or slits. This is achieved by passing the coil through a set of circular knives or rotary slitters that make longitudinal cuts along the length of the coil. The number of slits and their widths can be adjusted based on the requirements.
  2. Precision Cutting: Metal slitting machines are designed to make precise and consistent cuts along the entire length of the coil. They are equipped with precise controls and adjustments to ensure accurate slitting widths and minimize deviations. This is crucial for maintaining uniformity and quality in the final slit strips.
  3. Recoiling: Once the metal coil is slit into narrower strips, the machine can also rewind or recoiling the individual strips into separate coils. This process involves winding each slit strip onto individual recoiler mandrels, creating smaller coils that are easier to handle and transport.
  4. Edge Trimming: Metal slitting machines often have the capability to trim the edges of the slit strips to remove any irregularities or burrs. This ensures clean and smooth edges on the finished strips, improving their quality and usability.
  5. Tension Control: Maintaining proper tension throughout the slitting process is crucial to ensure accurate and consistent cuts. Metal slitting machines are equipped with tension control systems that apply the appropriate tension to the metal coil, preventing issues such as material stretching or wrinkling during the slitting operation.
  6. Speed and Efficiency: Metal slitting machines are designed to operate at high speeds, allowing for efficient processing of large coils. They are equipped with advanced automation features and controls to optimize the slitting process, reducing downtime and increasing productivity.

Overall, the function of a metal slitting machine is to transform wide coils of metal into narrower strips with precise cuts, suitable for further processing, manufacturing, or distribution in various industries.

What is the difference between sliding line machines and roll sliding machines?

Slitting Line Machine and Roll Slitting Machine are both equipment used for cutting metal, but they have some differences in terms of operation, application range, and cutting method.

  1. Operation: A Slitting Line Machine is an automated production line equipment typically consisting of multiple components, including coil loading/unloading, decoiler, slitter, and recoiler. They complete the process of metal coil unwinding, cutting, and rewinding in a continuous flow. On the other hand, a Roll Slitting Machine is a standalone cutting machine that performs cutting by unloading the metal coil from one shaft and rewinding it onto another shaft.
  2. Application Range: Slitting Line Machines are commonly used for large-scale metal coil processing and production line manufacturing. They are suitable for wider and thicker metal coils. They can handle larger diameters and weights of coils and have higher production capacity. Roll Slitting Machines are suitable for smaller-scale cutting needs and are designed for narrower and thinner metal coils.
  3. Cutting Method: Slitting Line Machines typically employ multiple rotating blades for the cutting process, slicing the metal coil along its length into multiple narrower strips. The cutting width and quantity can be controlled by adjusting the position and number of the blades. Roll Slitting Machines generally use a single blade or cutting wheel to cut the metal coil, resulting in narrower cutting widths.

In summary, Slitting Line Machines are suitable for large-scale metal coil processing and production line manufacturing, offering high automation and production capacity. Roll Slitting Machines are suitable for smaller-scale cutting needs and can handle narrower and thinner metal coils.

Why Sussman Different

The price of Sussman’s roll forming machines is a little higher than other suppliers’. Let me explain about our machines difference:

Sussman machine design: it is unit one, which means the control box and the hydraulic station are all put under the machine frame, when you get the machine, no need to assemble and connect the complicate cable of the machine, you only need to connect one main cable, then the machine is working. It saves more time and space.

Our display screen is touch screen, not text touch screen.

Sussman Machinery

Sussman Processing technology: Sussman rollers is through grinding, quenched, chroming,finish machining,polishing,coated with chrome 0.05mm, all rollers are shiny, stronger and avoid rust.etc to make stronger, the roll forming machine is more robust and easier to use.  The metal sheet produced by our machine is always flat and perfect profiles., because in the design and during the machining process, we always control the force for the metal sheet, it does not damage the sheet surface and comes out perfect profile. And we use the German application COPRA, to imitate the situation in 3D and ensure the perfect profile.

Sussman Machinery

Sussman roll forming system

Sussman roll forming system: We will make the hand wheels at the feeding device to adjust feeding width, and we also make the wheels with the numbers then you know how to adjust right and left sides, also we made the rulers on the bedding, you can adjust the profile height and width according to the rulers.
