Abstract
A machine (Fig. 2) for producing a saddle-stapled booklet has a trayfor receiving and registering sheets to form a group of sheets. The group of sheets is moved horizontally between the upper edge of a vertically movable folder blade (4) between a pair of parallel, side-by-side rollers (2) to fold the sheets. Continued upward movement of the blade (4) drives the folded group of sheets against a pair of staplers (1,1). The booklet thus produced is rejected laterally by a pair of crease-forming rollers (3) disposed side-by-side and rotatable in parallel vertical axes.
Description
- This invention relates to a machine and a method for producing saddle-stapled booklets. A "saddle-stapled booklet" is a number of printed sheets, for example of A4 size paper, which are folded in half as a group, to A5 size, and then stapled along the fold, to form the saddle-stapled booklet.
- To produce such booklets it is known to use apparatus which is part of a printing machine and which mass-produces the booklets by folding the sheets of paper . in groups and by stitching the folded groups. It is also known to use several separate devices, firstly a folding device, then a jogging and gathering device, and then a stapling device.
- The known machines are either large and expensive, or involve handling of paper between several devices.
- There is thus a requirement for a relatively simple and relatively inexpensive single machine which can produce booklets quickly and in quantity.
- According to one aspect of this invention, a machine for producing saddle-stapled booklets comprises a tray for forming a group of sheets; a folder blade or saddle for engaging and moving the group of sheets between fold-forming members for folding the group of sheets and for pushing the folded group of sheets at the fold against a stapling device for insertion of staples through the folded sheets; and means for ejecting the folded and stapled booklet. Preferably the tray is horizontal and includes devices for registering sheets to form the group of sheets. The fold-forming members preferably comprise a pair of parallel and horizontal rollers, spaced a small distance apart, so that the sheets are pushed by the folder blade between the rollers to fold the group of sheets centrally. Preferably also the folder blade or saddle is driven upwardly in a single vertical plane and in a continuous movement to fold the group of sheets and then to push it against the stapling device. The latter preferably comprises a number of staplers, the number of staplers corresponding to the number of staples required to be inserted in the group of sheets.
- According to another aspect of this invention, a method for producing saddle-stapled booklets comprises the steps of:- forming a group of sheets; moving the formed group of sheets to a position between a folder blade on the one hand and a stapling device on the other; and causing the blade to engage and move the group of sheets in a continuous movement and in a single plane firstly between fold-forming members so as to form a group of sheets folded along a fold line, and secondly against the stapling device for insertion of staples through the sheets at the fold line to form a booklet.
- An embodiment of the invention will now be described by way of example, with reference to the accompanying diagrammatic drawings, in which:-
- Figure 1 is a diagrammatic side elevation of the machine, as seen from the ejection side;
- Figure 2 is a diagrammatic front elevation of the machine, as seen from the left hand side of Figure 1; and
- Figure 3 is a diagrammatic top plan view of the machine.
- In Figure 2 the input side of the machine is to the left and the ejection or output side to the right. In Figure 3 the input side is at the top and the ejection side at the bottom. The several Figures are drawn to different scales.
- Referring to the drawings, two
staplers staplers parallel rollers 2, between which is a small gap, Fig. 1. Centrally below the gap is a folder saddle orblade 4 mounted for up and down movement by pins 4A,4A slidable in vertical bores inframe pillars lower part 4C of theblade 4 has a slot 4D in which is received acrank pin 5A on acrank arm 5 which is mounted on and rotatable by ashaft 5B. Anelectric motor 8 drives theshaft 5B by way of a gearbox 9,shaft 9A,belt 10, shaft 6A, and amagnetic clutch 6. The electric motor also drives a pair of crease-forming andbooklet ejecting rollers shaft 9B,belt 10A,idler pulley 11, andbelt 10B. - Electrical and control elements will not be described, but operation of the machine can be virtually automatic once the sheets of paper are placed ready in a stacking and aligning tray. The latter is not shown, but is a horizontal tray disposed at a level (Fig. 2) such that a group of sheets, stacked and aligned on the tray, will be level with the gap between the top of the
folder blade 4 and therollers 2, and will be moved horizontally from the tray to be engaged by the top surface of theblade 4. - To form a booklet, a group of for example 15 to 17 printed A4 sheets are placed in the tray, which is constructed so as to register the group of sheets accurately. Then the horizontally lying group of registered sheets is moved horizontally and to the right (Fig. 2) centrally above the
blade 4 into the space between theblade 4 and therollers rollers folder blade 4 which in Fig. 1 is seen between the booklet creasing and ejectingrollers folder blade 4, the latter is driven upwardly and carries the group of sheets upwardly in a vertical plane into the gap between therollers - The
blade 4 acts not only as a folder bar, but as a saddle or anvil and in its upper edge has two spaced staple-receiving recesses lA,lA, Fig. 2. - The upward motion of the
blade 4 continues, so driving the fold of the booklet against two staples, one of which projects from eachstapler 1. The staples are driven through the thicknesses of folded paper, and are bent over by the two recesses in the top edge of theblade 4. Thus the folder blade drives the group of . sheets upwardly in a single continuous motion in a vertical plane. Firstly it causes the group of sheets to be folded by therollers staplers - The
blade 4 then descends, on continued rotation of thecrank 5, until the fold of the booklet is in the space below therollers shaft 13A, strikes the left hand end of the booklet and drives it to the right so that the fold of the booklet is caught between theknurled ejection rollers - In a prototype machine, a time of only four seconds was required, from placing a group of sheets on the tray, to ejection of the folded and stapled booklet from the machine.
- Although the above-described embodiment uses- an upwardly driven folder and stapling blade, it would be possible for instance to reverse the arrangement, so that the group of sheets of paper was driven downwardly on to staplers. Also the particular drive arrangement shown could be replaced by other forms of drive.
