Automatic Reel Change

Definition: Automatic Reel Change is a mechanism used in rotary machines to seamlessly attach a new reel of material to an existing one without stopping the machine. This process eliminates the need to stop production and manually sever the old web, thus ensuring continuous operation.

Key Features

  1. Automatic Paster:
  • Function: Automatically attaches a new reel to the end of the old web.
  • Operation: Utilizes equipment that performs the attachment and pasting processes while the machine is still running.
  1. Flying Paster:
  • Function: Similar to the automatic paster but specifically refers to the capability of performing the reel change while the machine is operating at high speeds.
  • Operation: Ensures continuous material flow by seamlessly joining the new reel with the old one without interrupting the machine’s operation.

Operation

  • Web Attachment: The system uses specialized mechanisms to join the end of the old web with the start of a new reel. This often involves a combination of mechanical, pneumatic, or adhesive techniques.
  • Seamless Transition: The transition is made smoothly, avoiding any gaps or overlaps in the material web. This is crucial for maintaining the quality and consistency of the output.

Applications

  1. Printing Industry:
  • Used in high-speed printing presses to ensure continuous printing without interruptions for reel changes.
  1. Paper and Film Production:
  • Employed in processes where large rolls of paper or film are used, allowing for uninterrupted production while changing reels.
  1. Packaging:
  • Utilized in packaging machines that require continuous material feeding for wrapping and sealing products.

Advantages

  • Increased Efficiency: Eliminates downtime associated with manual reel changes, leading to higher production rates and efficiency.
  • Consistent Quality: Ensures a smooth and uninterrupted material flow, which is essential for maintaining the quality of the final product.
  • Reduced Labor: Minimizes the need for manual intervention, reducing labor costs and potential for human error.

Summary

Automatic Reel Change (also known as autopaster or flying paster) is a critical technology in rotary machines that enables the seamless attachment of new reels to existing webs without halting production. This system is essential in industries such as printing, paper production, and packaging, where continuous operation and high efficiency are crucial. It enhances production efficiency, maintains product quality, and reduces labor requirements.
