HOWARINE CALVERT HOWARLEIM 100 & 200
For production of perfect bound, open flat books with 2 cold adhesives
It is now possible to produce open flat, perfect bound books, up to 3 inches thick, without having to buy expensive machinery. Only 2 cold adhesives are required, Howarleim 100 and Howarleim 200, and two flat brushes.
The procedure is extremely simple. First apply a coat of Howarleim 100 to the spine of the collated and stacked sheets. This thin adhesive penetrates into the spin. After 10-15 minutes apply a thick coat of Howarleim 200 on the spine. The Howarleim 100 sucks the Howarleim 200 into the book. When dry the result is a perfect bound, open flat and very strong book. If required a wrap around cover can be applied by putting an extra coat of Howarleim 200 on the spine.
With the Howarleim process all companies can make perfect bound books which previously would have required expensive hot melt binding equipment. Howarleim adhesives are available directly from GluesDirect.co.uk in 5 litre and 3 litre containers.

To make ‘open-flat’ books of bank, bond or M.F. paper without machinery Card Covers
• If book contains perforated leaves, allow margin of 4-5mm from spine edge to perforation. Stack books with covers interleaved, on bench or in Howapress with a thick strawboard on top – do not apply weight.
• Brush on a heavy application of HOWARLEIM 100.
• Make sure the left and right edges are well treated.
• Wait 5 minutes, apply full clamp pressure and brush on a thick coat of HOWARLEIM 200.
• When dry, slice apart between covers and apply spine tape to each book.
Wrap Around Covers
• Stack books WITHOUT covers, do not apply weight
• Brush on a heavy application of Howarleim 100, wait 5 minutes and then apply full pressure and brush on HOWARLEIM 200
• Smooth on a sheet of blank paper to the glued area for added strength
• When dry, slice off each book from pile, apply Howarleim 200 onto the spine and place in scored “wraparound” paper covers
