Definitions
- the present invention relates to a method of forming signatures for sending to a sewing machine, preferably but not necessarily obtained from sheets output by a photocopying machine, in a production line for the reprographic production of books.
- the problem tackled by the present invention is that of devising a method of the specified type, and also a folding machine for carrying it out, which will overcome the disadvantages cited above with reference to the prior art.
- This problem is solved by a method of the specified type that is characterized in that it includes a stage in which the sheets are folded into an approximate omega shape, resulting in signatures in which a section of each leaf beginning at the spine is closed and the remaining section of each leaf further from the spine is open.
- 1 is a general indication for a line for the reprographic production of books.
- the production line 1 comprises a sewing machine 2 for sewing the signatures, which are all marked 3.
- the sewing machine 2 is known per se and is provided with a mobile saddle 4 and a fixed saddle 5, these both extending in a longitudinal direction X-X.
- each signature 3 there is a spine or back 6 and two leaves 7 extending from the spine.
- the production line 1 also comprises a folding machine 8 which is situated upstream of the sewing machine 2.
- the folding machine 8 is for forming the signatures 3 which are then passed to the sewing machine 1.
- the signatures 3 are preferably but not exclusively produced from sheets 9 output by a photocopying machine (conventional per se) situated upstream of the folding machine 8 and not illustrated in the figure.
- the folding machine 8 comprises in a frame 10 a paper holder 11, containing a load 12 of sheets 9 produced by the photocopying machine and photocopied by the latter in a manner known per se.
- a folding station 13 that comprises a sloping slide 14.
- the sheets follow a path, marked 15, from the paper holder 11 to the slide 14 along a transverse direction Y-Y perpendicular to the direction X-X.
- a slit 16 is formed in the slide 14, through which a folding blade 17 can pass.
- the folding blade 17 is movable, under the action of drive means 18 consisting for example of a motor 19 and a crank-and-rod mechanism 20, between a retracted position, in which the blade is completely withdrawn below the slide and a projecting position in which it rises above the slide to a specified distance marked A.
- the slit 16 divides the slide 14 into an upward section 21 and a downward section 22.
- a stop 23 On the downward section 22 of the slide 14 is a stop 23 which can be adjusted to arrest a sheet 9 to be folded, in such a way that the centre line of the sheet is over the slit 16.
- the stop 23 is thus positioned at a distance B from the slit 16 substantially equal to half the total width of the sheet to be folded, that is to say equal to the width of the leaf 7 of the signature 3 that is to be formed. It is important to note that the distance A to which the blade is to be raised above the slide 14 is less than the said distance B, e.g. it is between one quarter and one half of the distance B and preferably equal to one third of the distance B.
- a fixed striker plate 24 On board the frame 10 is a fixed striker plate 24 arranged transversely to the path of the sheets 15 and parallel to the slit 16 below it.
- the fixed striker plate 24 is positioned at a specified distance from the slide, substantially equal to the projection A of the blade, so that an edge 25 of the folding blade 17 comes into virtual pressing contact with it.
- Two jaws 26 and 27 travel in a guided manner on board the frame 10 so as to be movable along the transverse axis Y-Y in opposite directions to each other.
- Each jaw 26 and 27 has an active head 28 and 29, respectively, that oppose each other and face opposite sides 30 and 31 of the folding blade 17 when the latter rises above the slide.
- the jaws 26 and 27 have respective faces 32 and 33.
- Each face 32 and 33 lies above a respective section of the slide: specifically face 32 lies above the upward section 21 and face 33 lies above the downward section 22.
- the jaws 26 and 27 are driven by drive means 34 and 35, between respective positions in which the heads of the jaws are far apart and respective positions in which the heads are brought into pressing contact with each other.
- the drive means 34 and 35 are preferably pneumatic, and comprise, for each jaw that is to be driven, a cylinder-and-piston unit 36 powered by compressed air from a line 37 that includes a pressure regulating valve 38. Each cylinder-and-piston unit 36 acts on its particular jaw via a knuckle-joint mechanism 39.
- An approximately omega-shaped seat 40 is defined inside the folding machine 8 according to the invention, said seat 40 having an upper section 41, two opposing lateral sections 42 and 43 and two base sections 44 and 45.
- the upper section 41 is defined between the striker plate 24 and the edge 25 of the folding blade.
- the lateral sections 42 and 43 are defined between the head 28 of the jaw 26 and the side 30 of the folding blade 17, and between the head of the jaw 27 and the side 31 of the same folding blade, respectively.
- the base sections 44 and 45 are defined between the face 32 of the jaw 26 and the upward section 21 of the slide 14, and between the face 33 of the jaw 27 and the downward section 22 of the same slide, respectively.
- the said seat 40 is designed to accommodate a sheet 9 and form a signature 3 in the manner described below.
- a sheet 9 referring to the folding machine in an initial condition (see Figure 4), in which the folding blade is in its retracted position and the jaws are apart from each other, positions itself on the slide 14 against the stop 23.
- the sheet 9 is folded in such a way that its central portion extends between the jaws 26 and 27 and lies astride the folding blade 17, where it is stopped by the striker plate 24, and the remaining edge portions still lie on the slide 14.
- the blade is then retracted into its withdrawn position in the slide (see Figure 6).
- the jaws are now pushed together (see Figure 7) and close on the sheet, thereby forming the spine 6 and the signature 3.
- the only part of the signature that is closed is a section marked 7a of the leaves 7, whose length is equal to the above-mentioned distance A.
- Remaining sections, marked 7b, of the leaves 7 are still trapped between the faces of the heads and the upward and downward sections of the slide.
- the signature 3 has now been formed, but the only part that is closed is a section 7a of each leaf 7 extending from the spine 6, and the remaining sections 7b of the leaves further from the spine are still open.
- the present invention provides a method of forming signatures for sending to a sewing machine, preferably but not necessarily obtained from sheets output by a photocopying machine, in a production line for the reprographic production of books, with the aid of a stage in which the sheets are folded into an approximate omega shape, resulting in signatures in which a section of each leaf beginning at the spine is closed and the remaining section of each leaf further from the spine is open.
- the main advantage of the folding method and machine according to the present invention is that the signatures obtained can be shot directly through to straddle the fixed saddle of the sewing machine, with unusually fast cycle times and with unusually continuous and reliable output.
- Another advantage of the invention is the versatility with which signatures of different thicknesses can be formed, because the pneumatic drive of the two jaws allows them to stop automatically one against the other on either side of the signature, whatever the thickness of the signature.
- Another advantage of the method and machine according to the present invention is the reliability with which books are produced, due to the complete elimination of delicate components such as suckers and grippers and the like, which have had to be employed hitherto for opening signatures before laying them astride the saddle.
