Abstract: A small booklet binding machine is presented for use in financial institutions to produce onsite, in an economical and expedient fashion, bound booklets for use as checkbooks, loan coupon books, or other forms of small booklets. A user places paper stock to be processed by the machine into an input tray. The user then places backer cards into the machine. The machine automatically advances the paper stock through a pair of rollers, which substantially slit the paper stock into a plurality of checks which are collated in a collector tray. When the machine has advanced and slit all of the paper stock in the input tray, the collector tray rotates to allow a stapler to secure the plurality of checks to the backer cards. The collector tray then rotates to allow a user to remove the bound checks from the machine. Operationally, the machine produces bound checkbooks, or loan coupon books, without user intervention, other than supplying the machine with backer cards.
