ABSTRACT:
The apparatus is the justifying station of an automatic bookbinding machine which stages collection of the sheets of the book, justifies the side and end edges of the sheets, feeds male and female plastic bookbinding strips one at a time from cassettes, assembles the sheets and strips and then binds the book. In the sheet justifying apparatus the sheets are deposited on an originally horizontal movable jaw. The latter is then raised toward a stationary jaw until the sheets are loosely clamped. Thereupon the jaws with sheets therebetween are pivotted to vertical position. A first side guide is caused to reciprocate rapidly against one side edge of the stack of shets, justifying the opposite edge against a stationary guide on the opposite side edge. Simultaneously, a front edge of the stack, justifying the rear edge against a stationary base plate.
