The Intelli-Bind IB400 comb binding machine is a highly versatile model that may be used for a variety of office binding projects. All punching pins can disengage for convenient custom punching and binding. The inserted paper is manually punched with an easy-to-use punch handle. The IB400 is capable of punching up to 18 sheets at a time, depending on the weight of the paper stock. The IB400 comes fully loaded with a comb opener/closer that is also manually operated. This model features a sleek, compact design and is ideal for low- to medium-volume document binding. The IB400 may be used to professionally bind books (with plastic combs) up to one-inch in thickness without any hassles. Be sure to contact Intelli-Zone for more information today.
