Complementary elements

Vertical rammer for slit coils

At SAIZAR, we integrate this system, known as a vertical rammer for slit coils, into a turnstile. It is a complementary element designed for the final stage of the slitting line process, when operations require working on a turnstile to perform circumferential strapping in that position. 

In practice, the vertical rammer with down fingers helps keep the material under control during handling and coil processing. This type of equipment is used to prevent the strip ends from loosening and to reduce the risk of damage to the material during handling.

By securing the strip ends and providing specific slots for strap passage, automatic strapping can then be carried out, without releasing the vertical rammer until all planned strapping cycles have been completed.

How we design this system at SAIZAR

We design the vertical rammer as an integrated piece of equipment within the installation, rather than as a standalone element. It is configured based on how the coils are positioned during the strapping process, the type of turnstile, and the layout of nearby equipment such as the slitting line coil car. At the same time, the automatic strapping machine is designed to operate in these conditions, carrying out the full process of coil clamping and strapping automatically.

Integration on a Turnstile

The vertical rammer with down fingers for slit coils can be adapted to any type of configuration, coil dimensions, rotating turret design, and different strapping position requirements.

Clamping and Control of the Tips of Slit Coils

In these applications, the objective of the system is to keep all strap ends under control while the slit coil remains in the working position. To achieve this, the customer must have a shear in the slitting line, ensuring that all the tips of slit coils are collected in a same position.

The vertical rammer has multiple down fingers features where the tips of slit coils are secured, while leaving the necessary space for strap passage.

Adaptation to the Strapping Process

The vertical rammer is designed in coordination with the automatic strapping machine itself. For this purpose, information about the tunstile, the slitting line coil car, and the different coil specifications is required.

Typical Features of This System:

  • Integration as a complementary element within the slit coil strapping process.
  • Specific application on a turnstiles.
  • Coordination with the strapping machine and coil car.
  • Design adapted to line requirements and coil working position.

Typical Applications

This system is particularly well suited for slit coils, where circumferential strapping is performed with the coils positioned within the arm of the turnstile, or in configurations where material control during handling is critical to process stability.

With this system, all tips of slit coils are securely held before and during the strapping process, and only released once all strapping operations have been completed.

Benefits on the Production Floor

Integrating the vertical rammer into the line helps the slit coil to be handled in a more controlled and consistent condition during the strapping process. When the system is correctly sized, it contributes to a more stable strapping station operation and improved material management on the coil.

Typical benefits of this solution:

  • Better control of the tip of slit coil during handling and processing.
  • Greater consistency between coil position and the strapping station.
  • Increased productivity by freeing up the slitting line and unloading coil car.
  • A solution adapted to the turnstile and overall plant layout.

What We Need to Prepare a Proposal

To correctly define this system, we need to know the slit coil dimensions, the coil car characteristics, the turnstile specifications, and the working cycle of the different machines. Among other things, SAIZAR requests information about the slit coil, including inner diameter, outer diameter, width, strip thickness, number of coils placed, coil positioning on the arm, productivity, and available space.

It is also important to understand how the other machines in the line are configured and how they interact within the process. 

Typical information required to prepare a quotation:

  • Coil type and main dimensions.
  • Coil position on the turnstile arm.
  • Layout drawings of the turnstile and coil car.
  • Available space.

Frequently Asked Questions (FAQ)

What exactly is a vertical rammer?

It is a complementary system for slitting lines that helps keep the material secured prior to strapping operations. This equipment is installed on the turnstile and must be synchronised with other systems such as the coil car and the automatic strapping machine.

Mainly in slit coil applications, at the exit of the slitting line and prior to circumferential strapping operations.

We design it as a complementary element within the slitting line exit section for the strapping process.

Yes, it is primarily designed to be installed on a turnstile.

The down fingers are designed based on slit coil widths, the space required for strap passage, and the different slit coil combinations that may be positioned on the tunstile. There are slotted and liftable down fingers, both allowing strap passage.

Slit coil type, dimensions, coil working position, strapping width, and layout drawings of the coiul car and turnstile.

It provides a more controlled working condition over the strip and improves integration between coil handling and the strapping station. Without this solution, the operator would need to perform strapping either on the slitting line itself or with the coils positioned on the coil car, slowing down the customer’s production process.

Yes, SAIZAR designs these systems as part of complete circumferential coil strapping solutions and provides technical service and spare parts support for its projects.
