Device and method for casing books

Claim 1

Apparatus for assembling an uncased book to a case of the type having a central flexible spine section having an exposed pressure-sensitive inside surface, said apparatus comprising a table dimensioned to support said case Laid out substantially flat with said pressure-sensitive inside surface uppermost with spaced holes positioned along one side edge, an adjustably positioned side edge guide along one side edge of said table, said side edge guide comprising a detachable bar which is Tshaped in cross section and having pins to fit into said holes, a rod along the back of said table transverse to said side edge guide, means mounting said rod spaced above said table, first and second brackets pivotally mounted on said rod, means for fixing said brackets for pivotal movement together, first and second locators each formed of bar stock in generally truncated triangle shape fixed to said first and second brackets and having parallel sides perpendicular to said rod overlying said pressure-sensitive inside surface in one position and being remote from said inside surface in a second position whereby the spine edge of an uncased book may be slipped between said parallel sides to be forced into contact with said pressure-sensitive inside surface, a guide extending between said brackets transverse to said parallel sides, said guide limiting rearward movement of said spine edge of said uncased book, a series of pins projecting up from said table a short distance rearward of said guide whereby when the rear edge of said case engages said case rear edge locating means said case extends a short distance rearward of the rear edge of said spine edge.

Claim 4

A method of forming a cased book comprising providing an uncased book having a plurality of sheets, front and back end leaves on the outside of said uncased book, each said end leaf having pressure-sensitive material on its outer surface extending to the top, bottom and outside margins of said end leaves, first release paper covering all of said pressure-sensitive material, binding means binding said sheets and end leaves together along their spine margins with said end leaves securely bound to said sheets prior to assembly of said uncased book to a case; gauging the thickness of said uncased book adjacent its spine edge, selecting a case of the type comprising front and back covers, a flexible spine, covering means for the outsides of both said front and back covers of said spine, and a spine strip of resilient material extending longitudinally down the middle of said flexible spine covering having second pressure-sensitive material on its exposed surface, said case prior to adherence to said uncased book being adapted to encase a range of thicknesses of uncased books by reason of the flexibility of said spine; said selected case having a spine strip of a width greater than the spine width of said uncased book, positioning said case on a table with said spine strip uppermost, said table having a pair of locators pivotally mounted thereon for movement between a first position resting on said table and a second position remote from said table, removably positionable side guide means, case top edge guide means, and uncased book top edge guide means; removing said second pressure-sensitive material, locating said uncased book with its top end a fixed short distance below the corresponding end of said spine strip and centered laterally with respect to said spine strip, pressing said uncased book so that its spine edge adheres to said second pressure-sensitive adheSive, closing said case about said uncased book, removing said first release paper and applying pressure to said covers to cause adherence of said end leaves to the insides of said covers all the way to the outer edges of said end leaves and with the insides of the outer edges of said covers extending outwardly beyond the outer edges of said end leaves and being devoid of exposed adhesive beyond the outer edges of said end leaves, said step of gauging comprising resting the spine edge of said uncased book on said table between said locators with said locators in first position, moving said locators toward each other to engage opposite sides of the spine of said uncased book, observing the distance between said locators, removing said uncased book and pivoting said locators to second position, positioning side edge guide means on said table at a position dependent on the distance between said locators, said step of locating said case further comprising engaging the side edge of said case with said side edge guide means and the top edge of said case with said case top edge guide means, and in which said step of pressing said uncased book comprises pivoting said locators to first position, engaging the top edge of said uncased book against said top edge guide means and the spine of said book between said locators and pivoting said uncased book toward said spine strip with said top edge guide as a fulcrum.

Claim 5

A method of forming a cased book comprising providing an uncased book having a plurality of sheets, front and back end leaves on the outside of said uncased book, each said end leaf having pressure-sensitive material on its outer surface extending to the top, bottom and outside margins of said end leaves, first release paper covering all of said pressure-sensitive material, binding means binding said sheets and end leaves together along their spine margins with said end leaves securely bound to said sheets prior to assembly of said uncased book to a case; gauging the thickness of said uncased book adjacent its spine edge, selecting a case of the type comprising front and back covers, a flexible spine, covering means for the outsides of both said front and back covers of said spine, and a spine strip of resilient material extending longitudinally down the middle of said flexible spine covering having second pressure-sensitive material on its exposed surface, said case prior to adherence to said uncased book being adapted to encase a range of thicknesses of uncased books by reason of the flexibility of said spine; said selected case having a spine strip of a width greater than the spine width of said uncased book, positioning said case on a table with said spine strip uppermost, said table having a pair of locators pivotally mounted thereon for movement between a first position resting on said table and a second position remote from said table, removably positionable side guide means, case top edge guide means, and uncased book top edge guide means; removing said second pressure-sensitive material, locating said uncased book with its top end a fixed short distance below the corresponding end of said spine strip and centered laterally with respect to said spine strip, pressing said uncased book so that its spine edge adheres to said second pressure-sensitive adheSive, closing said case about said uncased book, removing said first release paper and applying pressure to said covers to cause adherence of said end leaves to the insides of said covers all the way to the outer edges of said end leaves and with the insides of the outer edges of said covers extending outwardly beyond the outer edges of said end leaves and being devoid of exposed adhesive beyond the outer edges of said end leaves, said step of gauging comprising resting the spine edge of said uncased book on said table between said locators with said locators in first position, moving said locators toward each other to engage opposite sides of the spine of said uncased book, observing the distance between said locators, removing said uncased book and pivoting said locators to second position, positioning side edge guide means on said table at a position dependent on the distance between said locators, said step of locating said case further comprising engaging the side edge of said case with said side edge guide means and the top edge of said case with said case top edge guide means, and in which said step of pressing said uncased book comprises pivoting said locators to first position, engaging the top edge of said uncased book against said top edge guide means and the spine of said book between said locators and pivoting said uncased book toward said spine strip with said top edge guide as a fulcrum.
