The RILECART B-535 combines both economy and complete automation. The B-535 is a fully automatic double loop wire binder capable of binding books at the brisk pace of 3,000 per hour. The operator drops a book on the conveyor and the B-535 does the rest. That's right-- it inserts the wire, crimps the wire, and delivers the book onto a conveyor. The machine will bind books from 3.25 X 4 inches up to 12 X 12-1/2 inches. Spiral diameters can range from 1/4 of an inch to 1 1/4 inch, allowing for a maximum book thickness of one inch. Skip binding up to five parts is attainable. An in-line punching section is optional. A calendar machine is also available.
