HOW IT WORKS: Wire is available in two patterns - 2 loops (2:1 pitch) per inch or 3 loops (3:1 pitch) per inch. The number of holes in the documents must match the wire pattern. The wire comes "open" so that the punched pages can be inserted into the loops. After all of the pages are in place the book is inserted into a closing machine where a closing bar either electronically or manually closes the wire to a predetermined diameter, making a round, sealed bind.
PRODUCTION SPEED: Depending on
thickness, up to 300 per hour for ¼" book.
MAX FINISH SIZE: 12 x 18 inches.
DOCUMENT THICKNESS: 3/16" to bind up to 30 sheets through 1½" to bind up to 310 sheets of 20# bond.
