The DB-280 Perfect Binding & Padding Machine is a user friendly perfect binder that offers professional professional results. A double pass over the roughening cutter provides superior notching to ensure superb glue penetration for a strong finished bind. Innovative features of the DB-280 Perfect Binder & Padder include two glue drums that provide a more durable bind and additional glue capacity. With a quick push of a button, the DB-280's perfect binding capabilities can convert to a padding function where only the precise amount of glue is added to complete perfectly bound note pads. A safety cover on the notching blade ensures operator safety. Duplo DB-280 Padding Glue & Perfect Binding Adhesive is packaged in a 35 lb. box.
The number of books you can make is called the "yield". To determine the glue yield for perfect binding books, you can use the below formula, which includes the spine dimensions of your specific books (since books can vary in size quite a bit, and yield will vary just as much). This formula is based on the main compartment capacity, which is about 9 lbs of glue, even though the glue bag is larger.
Formula: (0.02 x book thickness x length of book spine = X), then (X ÷ 231 = Y), then (Y x 9 = Z), then (50 ÷ Z = total books)
Sample: If I have a book that is 11" high with a 2" thick spine, I would take:
\n • 0.02 x 2 x 11 = 0.44
\n • 0.44 ÷ 231 = 0.00190476
\n • 0.00190476 x 9 = 0.01714284
\n • 50 ÷ 0.01714284 = 2,916 total books
\nSince your books may be a different size, simply change-out those two dimensions for your spine height and book thickness to calculate the number of your books that can be made. And remember, this yield is based on the 9 lbs of glue that the machine can hold in the main compartment, and the glue bags are sold in larger (higher pounds) bags, so will have a different overall yield.
