With its EcoBinder, Kugler-Womako, a Körber PaperLink Group company, is introducing a new ring binding made from paper. The EcoBinder uses a rotary indexing table instead of the traditional linear transfer unit to bind product with the paper rings.
This new binding technique eliminates the need to separate the binding from the paper product before recycling.
Anton Jost, EcoBinder project manager, explains how the rotary indexing table came to be used for the ring paper binding: "A rotary indexing table is more compact than a linear transfer unit, consists of fewer parts, is therefore less expensive and requires less maintenance.”
Jost describes the single-operator processing sequence: "In the first station, the pad of paper is inserted manually. The pad always remains fixed in the rotary indexing table and is transported." In the next converting step, the printed paper strips are automatically rolled into a double ring and, at the same time, glued together with hot glue. A third step connects the protruding tabs with the rear cover of the pad. The tabs ensure that printing on the paper rings always points in a defined direction. This provides a fixed "back" for decorative elements and markings on the binder rings. Because individual paper strips are processed, the rings can be colored and printed differently. The fourth station is used for delivering the finished pads.
"This configuration is only one of many possibilities," says Jost. "A fully automatic binding machine with up to 12 stations and fully automatic feeding is already being planned."
