A “balloon former” in the context of rotary presses refers to an additional former used in the production of multi-sectioned newspapers or magazines. Here’s how it works:
- Function: The balloon former is positioned above other formers on a rotary press. Its primary function is to gather folded webs of paper, which are then used to create the sections of a multi-sectioned newspaper or magazine.
- Operation: As the press runs, paper webs are fed into the machine. Each web is folded and then gathered by the balloon former. This gathering process ensures that multiple folded webs are brought together in proper alignment to form a complete section of the publication.
- Importance: Balloon formers are crucial for maintaining the correct sequence and alignment of sections in a multi-sectioned publication. They help ensure that each section is accurately assembled and ready for further processing, such as binding or additional printing.
- Usage in Printing Industry: Balloon formers are especially common in high-speed rotary printing presses used in the newspaper and magazine industries. They facilitate efficient production by automating the gathering and alignment of folded paper webs.
Overall, the balloon former plays a pivotal role in the smooth operation of rotary presses, contributing to the precision and efficiency required in the mass production of multi-sectioned newspapers and magazines.
