RINGS THAT BIND
WEISS TR 750 ROTARY INDEXING TABLES FACILLITATE SPACE & COST SAVINGS FOR RECYCLABLE BINDING SYSTEM

Abstract: When compared to a linear design, the WEISS TR 750 rotary indexing table broke new ground for Kugler-Womako by saving space and moving the infeed and output areas of the blocks closer together − offering a particular advantage for manual operations. Essentially, because a rotary indexing table is made up of significantly fewer parts than a transfer line, it was also possible to lower the cost for the binding machine while increasing production quality.
BINDING / RING COLLABORATION
BINDING / RING PRODUCTION-PROCESSING
The goal of the production processing was to achieve thick wound paper strips that are rolled up and held in place using hot glue that fits into slots on the spines of books − instead of wire or plastic. This produces a ring binding system that is far more than just recyclable and safe, but also achieves a USP not to be underestimated − saving customers an impressive 50% in material costs for binding.
In the first station of the processing sequence the block is inserted by hand. Unlike linear production, where each processing stage requires intervention, the block always remains fixed in the rotary indexing table and is transported gently onwards to the next step. The combination of the high part and repeat accuracy of the WEISS TR series tables leads to outstanding manufacturing precision. Notably, secure locking without further indexing or fixing steps, a feature typical of rotary tables, also allows for high speeds of up to 30 cycles per minute.
In the subsequent processing station, the printed strips of paper are rolled up and stuck together at the same time using hot glue. A third station attaches the protruding straps to the rear cover of the block to ensure that the images or text printed on the paper rings always remain in the desired position. The fourth station is ultimately used to remove the finished blocks. The close proximity of infeed and output is another advantage over a linear arrangement − particularly when filling by hand.
Even with up to 12 stations, this machine wouldn’t prove to be a problem for the WEISS TR series which offers ring diameters of up to 2,200 mm – providing more than enough scope for coupling with processing stations.
Jost noted the mechanical integration capabilities of the rotary indexing rings from WEISS, “We were able to connect the frequency inverter control on the TR 750 to our higher level machine control system with no issues. In fact, the binding machine was already up and running just a few hours after installation.”
BINDING / RING CONCLUSION
When compared to a linear design, the WEISS TR 750 rotary indexing table broke new ground for Kugler-Womako by saving space and moving the infeed and output areas of the blocks closer together − offering a particular advantage for manual operations. Essentially, because a rotary indexing table is made up of significantly fewer parts than a transfer line, it was also possible to lower the cost for the binding machine while increasing production quality.
According to Jost, “As a custom machine builder geared toward meeting the very specific wishes of its customers, no two machines are alike for us. This configuration is obviously just one of many options, and a fully automatic binding machine is already in the planning stages.”
Ultimately, the unique EcoBinder is an environmentally friendly, safe, and affordable solution to conventional wire or plastic ring binding. What makes the system even more attractive is the fact that the paper rings can be individually printed for advertising or labelling purposes, and the binding cannot be opened −
making it the ideal solution for permanent records.
