The module (3) comprises a frame having vertical pillars (30A, 30B), a rotary turnover structure (4) arranged horizontally between the vertical pillars and comprising rotation shafts (400A) supported by bearings (300A) with which the vertical pillars are respectively equipped. A motor (303B) applies a first mechanical torque to one of the rotation shafts when a folding package turnover is ordered in the machine. The module also comprises additional means (5) for applying a second mechanical torque to the other rotation shaft upon a folding package turnover.

The conveyor comprises two single-transport-belt conveyor subassemblies (42AL, 42AH) arranged facing each other symmetrically relative to a pinching plane of the conveyor (42A), two sets of rollers (423L, 423H) incorporated in the two conveyor subassemblies and distributed on either side of the pinching plane. A first set of rollers (423L) guides a belt (420AL) of the first conveyor subassembly and a second set of rollers (423H) guides a belt (420AH) of the second conveyor subassembly. The conveyor subassemblies comprise sets of vertically arranged jacks (424L, 424H) which are associated with the sets of rollers, each of the rollers being mounted on a dedicated respective jack.

Disclosed is a device for loading a bound product, the device holding a product without the product sagging, which has been completed by punching various objects to be bound and then binding same by means of a coil spring, reversing the moving direction to a loading location and thereby enabling neat and stable stacking in a zigzag state without having the coil springs come in contact with one another. A device for loading a bound product, according to the present invention, comprises: a supporting frame unit for providing a distance for the movement of a bound product from a binding location to a loading location; a transfer unit having upper and lower gears, which are axially mounted on one side of the frame unit, a driven gear, which is axially mounted on the other end, a moving belt, for connecting the lower gear and the driven gear, a power belt, which is connected to the upper gear, and a first driving motor, for transmitting power to the power belt; an LM guide having a rail, which is mounted on the frame unit in the length direction, and a block; a reversing unit having a supporting plate, which is fixed on the block of the LM guide and the moving belt, a pinion, of which the upper end is rotatably and axially mounted on the supporting plate, a first cylinder, for operating a rack gear that interlocks with the pinion, and a rotating plate which is fixed on the lower end of the pinion; and a holding unit having a support and a second cylinder which is mounted on the rotating plate of the reversing unit and has a pressure member coupled to the front end thereof so as to hold a bound product.

Provided is a bag loading apparatus including: a first loading unit configured to load bags of a first line; a second loading unit configured to load bags of a second line; a discharge unit; and a control unit, and the control unit controls the first loading unit to drop the plurality of bags of the first line from the first loading unit onto the discharge unit, controls the discharge unit to move the plurality of bags of the first line dropped onto the discharge unit to an area under the plurality of bags of the second line loaded on the second loading unit, and controls the second loading unit to drop the plurality of bags of the second line from the second loading unit-onto the plurality of bags of the first line.

A booklet making method includes: cutting a web of paper on one side and on another side into first and second continuous sheets, alternately bonding the first and second continuous sheets widthwise with a setting paste and a throwaway paste to form a double set continuous sheet of paper, and cutting the double set continuous sheet of paper into split double sheets of a selected longitudinal length. A plurality of split double sheets is integrally bound with an integrating paste to form a booklet-like product. Portions of the booklet-like product which are pasted and bonded with the throwaway paste are cut off to provide a plurality of booklets. Thus, by the booklet making method, booklets having an odd number of leaves or pages are formed without waste of paper and with reduced paper jams.
