- Tip: Fugitive glues can fool you when you are folding and gluing on the folder. If you try to open a completed piece immediately when it exits the folder, you will find that the piece will open easily. You will wonder if the bond is strong enough. Check pieces that have been setting for approximately three minutes to test the bond. You can asist the assurance of a good bond by setting the #5 Baumset to have a little more tension than normal.
- Tip: Note that cold glues have a limited shelf life. Do not order more glue than you will need Old glue will cause performance problems. Glue can be ordered in small containers at very reasonable prices.
- Tip: You can double your production of 8-1/2 in. x 11 in. self-mailers by printing them two-up on 11 in. x 17 in. paper. Fold & glue then slit into two streams as they exit the folder. Your glue system would need the capability to add additional gluing heads.
- Tip: When a job calls for using perforated tear-offs and/or spot gluing, it is helpful to the recipients if opening instructions are printed on the piece.
- Tip: When selecting your gluing system, investigate a system that provides a glue tank that is sized to accept the standard containers of glue supplied by the glue manufacturer without having to pour the glue into the glue tank. Being able to insert the manufacturer’s bottle into the tank allows you to quickly change glues with minimal clean-up maintenance.
- Tip: Where two glue lines are placed close together (for example, two-up work) the glue lines should use the same, but wider, roller groove. Each edge of the groove should be 5/32 inch from the center of the glue line. Note: A segmented fold roll is recommended for this type of application. (See “Folder Modification Terms”)
