Definitions
- This invention relates to methods of and apparatus for fastening together sheets of material, in particular apparatus that stitches and folds sheets of paper into book form.
- folding of sheets of paper into book form is meant the doubling over of a plurality of overlaid sheets of paper, usually a maximum of about twenty sheets, to form a pamphlet, brochure, magazine or the like.
- stitching is primarily meant the use of metal wire to fasten the sheets together, in the manner of staples.
- the machine can be opened and closed in the manner of a clam-shell, for inspection, for maintenance or to remove paper jams.
- the apparatus is easy to set up and can be operated by unskilled personnel.
- apparatus for stitching and folding sheets of material comprising in-feed means arranged to receive a plurality of overlaid sheets, stitching means arranged to insert at least one fastening stitch through the sheets, folding means to fold the stitched sheets, and out-feed means for the folded sheets, wherein the sheet path is downwards through the in-feed means, and the stitching and the initiation of the folding is effected on the sheets without the sheets leaving a rectilinear path which is a straight line continuation of the path through the in-feed means.
- apparatus for stitching and folding sheets of material comprising in-feed means for sheets of material, stitching means to stitch a plurality of said sheets together, folding means to fold the stitched sheets, and out-feed means, wherein the sheet path is downwards through the in-feed means and generally horizontally at about 90° to the in-feed direction through the out-feed means.
- apparatus for stitching and folding sheets of material comprising in-feed means for sheets of material, stitching means to stitch a plurality of said sheets together, folding means to fold the stitched sheets, and out-feed means, wherein the in-feed means the stitching means are pivotable relative to fixed- position folding means and fixed-position out-feed means.
- the invention also includes a method of stitching and folding sheets of material comprising the steps of feeding sheets of material downwards into in- feed means, holding the sheets at a first position and effecting stitching of the sheets together, moving the stitched sheets to a second position and effecting a folding of the sheets, and removing the folded sheets from the folding station, wherein the sheets follow a linear path from entry into the in-feed means until initiation of the folding.
- Fig. 1 shows the stitcher/folder machine in its closed, operative state
- Fig. 2 shows the machine in an opened state.
- the stitcher/folder machine shown in the drawings comprises an in-feed assembly, indicated generally at 10, which defines a downwardly directed receiving channel 12 (Fig. 1) for receiving a plurality of overlaid sheets of material, for example sheets of paper.
- the apparatus will be described hereinafter with reference to sheets of paper.
- the receiving channel 12 is essentially vertical in its attitude when the machine is closed up for operation. By “essentially vertical” is meant that the receiving channel is inclined at a relatively small angle off the true vertical.
- the channel must be set off vertical in order to prevent the sheets of paper from falling forwards, but it should be kept as vertical as possible consistent with maintaining stability of the stack of sheets in the channel. As shown in Fig.
- the angle of inclination from the vertical of the receiving channel 12 is about 20°.
- an endless belt 14 Centrally within the receiving channel and at the underside of the sheets of paper is an endless belt 14 which is guided around gearwheels and pulleys within the in-feed assembly and which is rotationally driven from the main drive of the machine by way of an in-feed driver 16.
- the endless belt 14 is provided with two projecting dogs 17, 18 which extend outwardly and which thus form abutments within the path of the sheets in the receiving channel.
- a joggle plate 20 At each side of the receiving channel 12 there is provided a joggle plate 20 (Fig.2).
- the joggle plates 20 can be moved back and forth perpendicular to the direction of movement of the sheets of paper in order to knock them from the sides into accurate overlaid registration.
- the dogs 17, 18 on the belt 14 are used to effect a top knocking of the sheets in an analogous manner to ensure accurate registration in the longitudinal direction.
- the stitch assembly is indicated generally at 22. It includes two reels 24 of stitching wire (only one of which is shown in the drawings) and is adapted in use to insert a pair of staples through the overlaid sheets of paper at the position indicated at A in Fig. 1.
- the stitch assembly 22 is conventional in structure and mode of operation and will therefore not be described in more detail.
- a knife-fold assembly is indicated generally at 26 and comprises a blade 28 which is reciprocally movable into and out of the linear path of the stack of sheets, as indicated by the double-headed arrow 30, under the control of a solenoid 32.
- the blade 28 extends the full width of the sheets of paper and preferably has an undulating leading edge, for example of generally sinusoidal shape, in order to provide better contact with the sheets of paper.
- the leading edge of the blade 28 is recessed slightly in the zones where the blade would otherwise strike the staples, in order to avoid any possible misalignment arising from the blade striking the staples.
- a fold plate assembly indicated generally at 34 which constitutes a carriage for a pair of stops.
- the first stop is a stitch stop 36 which, as shown in the drawings, is pivotable into and out of the linear path of the sheets of paper under the control of a solenoid 38.
- the stitch stop 36 is pivoted into the path of the sheets of paper and the lower edge of the stack of sheets rests against the stop. With the lower edge of the stack of sheets resting against the stitch stop, the upper edge of the stack of sheets is positioned at the point indicated at B in Fig. 1.
- the second stop is a fold stop 40, which is a fixed position stop against which the lower edge of the stack of sheets is arranged to rest when the stack is in the position ready to be folded. With the stack of sheets in this position the upper edge of the stack is positioned at the point indicated at C in Fig. 1.
- An out-feed conveyor is indicated generally at 42 and is powered to take the stitched and folded sheets from the folding assembly 26 out in a generally horizontal direction and at right angles to the path of the stack of sheets within the machine during the stitching and folding process.
- the out-feed conveyor 42 comprises upper and lower belts 43, 44 between which the folded sheets pass. When initially contacted by the blade 28 the sheets are guided and engaged by rollers 45, 47 before passing between the belts 43, 44.
- the main drive for the machine is indicated at 46.
- Control of the movement of the various sub- assemblies within the machine is effected from the main drive 46 by way of appropriate transmission means such as belts and gears, as indicated schematically in the drawings.
- the folding assembly 26 and the out-feed conveyor 42 are fixed in their relative positions.
- both the in-feed assembly 10 and the stitch assembly 22 are pivotable relative to the rest of the machine.
- the in-feed assembly 10 is pivotable through an angle of about 90° and the stitch assembly is shown as pivotable through an angle of approximately 70° between their "closed" positions and their "open” positions.
- the in-feed assembly 10 and the stitch assembly 22 are pivoted jointly through a common angle, instead of one being pivotable further than the other.
- the in-feed assembly 10 and the stitch assembly 22 can be pivoted relative to the rest of the apparatus in a fan-like movement around the drive shafts, in a clam-shell motion, all the functional parts of the machine are made readily accessible for adjustment, maintenance. repair or the removal of paper jams. It is to be noted that the various drives will remain engaged when the in-feed assembly and stitch assembly are pivoted into their opened position, thereby ensuring that the apparatus does not need to be readjusted or reset when the apparatus is closed up again for subsequent operation. The previously set positions will remain accurately set.
- adjustment means are provided to set the mechanisms and to permit the positions of for example the stops 36 and 40 to be set for different sizes of paper sheets.
- a stack of sheets of paper up to about 20 in number, is fed into the receiving channel 12.
- the stack of sheets may be the output of a collating machine, such as the collating machine described in our International patent application WO 91/04215.
- the stack of sheets which drops into the receiving channel is given a top knock by the dogs 17, 18 on the belt 14, which can move relative to the stack of sheets and thus bring the dogs into striking engagement with the upper and lower edges of the sheets, and then is given a side knock by the joggle plates 20.
- the stitch assembly 22 is then actuated to insert the wire stitches or staples through the sheets at A.
- the stitch stop 36 is then retracted by energisation of the solenoid 38 and the stitched sheets move downwards into contact with the fold stop 40.
- the folding blade 28 is then energised to move outwards towards the sheets, to strike them at the level of the wire stitches and cause them to be folded about the stitches and to be passed generally horizontally outwards through the out-feed conveyor 42.
- On the out-feed conveyor side of the blade 28 guide means are provided to assist in the folding of the sheets about their centre as the blade performs its folding function.
- the rollers 45 and 47 are provided to entrain the folded sheets at this position.
- the path followed by the sheets through the machine is extremely short and that the machine itself is extremely compact.
- the sheets move in a rectilinear path from their initial receipt into the machine until the initiation of the folding movement, whereafter they are moved substantially at right-angles to their previous path.
- the stitching operation and the initiation of the folding operation are both carried out on the stack of sheets of paper without the stack having departed from its initial path upon entry into the machine.
- the downward linear path of movement of the sheets means that one is using the weight of the sheets to assist in the process, in contrast to known ma ⁇ chines where the sheets are moved generally horizontally and where one is working against the weight of the sheets.
