The RENZ ERW wire binding machine is a 3:1 pitch wire binder that features a heavy-duty electric punch and high-efficiency manual wire closer for use in high-volume binding environments. The ERW’s powerful electric punch has a robust punching capacity of up to 25 sheets (based on 20 lb. paper) and is fan-cooled for consistent and reliable punching of up to 20,000 sheets per hour. Below is a step-by-step guide for binding books with the RENZ ERW wire binder:
- Connect the foot pedal to the machine, then attach the power cord. Plug the power cord into the wall and turn the binder on.
- Measure the total thickness of your unbound book to determine the diameter of the wire binding spine that will be used. The ERW has a measuring scale located toward the rear of the machine that allows you to easily and accurately find the best wire diameter based on the thickness of your document.
- Adjust the wire closer based on the diameter of the your wire using the scale located immediately above the wire closer itself. To set the wire closer, loosen the screw, position the indicator on the line that corresponds to the desired diameter, and tighten the screw to complete the adjustment.
- Set the punching depth using the depth margin control knob. The punching depth is the amount of space between the edge of the sheet and the holes that are punched, and is generally greater on thick books than thin books.
- Position the paper guides based on the sheet size of your document. This will keep the holes centered along the binding edge of your document.
- Use the disengaging dies to eliminate any holes that will be partially punched along the ends of your sheets. Dies are easily disengaged by pulling on the corresponding pins. If you need to re-engage a die that had been disengaged for a previous binding project, push the corresponding pin back into the machine until it stops.
- Insert the selected twin-loop binding wire into the wire holder. Place the wire in front of the wire holder, press down onto the back edge of the clamp to open it, push the binding spine under the clamp, and then release the clamp to hold the wire in an upright position. This will allow you to insert the the pages of your book onto the wire as they are punched.
