The folder which is folded with the aid o~ the apparatus in accordance with the invention is preferably of the kind illustrated and described in the Swedish Patent 7902871-8. By "folder" in this context is to be understood every kind of folder, booklet, file or the li~e of paperboard or plastics, intended to protect sheets of paper inserted in the folder, and rekain them with the aid of a bead or strip of binder applied to the inside of the folder spine.
- 2a -~2~J781~1 The slleet o material which forms a folder havina a spine and two covers after folding is denoted by 1 in Figure 1. A strip or bead 2 of a binder of th~ hot-melt glue type, which is in a solid condition at room temperature and which mel.ts when heated in conjunction with khe attachment of sheets of paper to the spine of the ready-folded folder, is applied centrally to the sheet o~.material between two opposing side edges thereof~ The ~ead 2, with~a cross section which is rectangular or in the shape of a circle segment has been applied ~o the sheet 1 in a machine, e.g.
of the type described in the cited patent, and which is indicated at 3 in Figure 1. Simultaneously with the applica-tiQn of the bead 2, crease lines on the sheet on.either side of the bead are formed in this machine to facilitate subse~uent manual folding of the sheet. In the present case, howevex, such crease lines are not necessary since they do not notably facilitate folding the sh~et with the inventive apparakus~ and they have thexefore not been sshown on the drawings.
The sheet 1 with its attached bead 2 fed out from the machine 3 is transferred via thrae rubber belts 5 to a table 4 attached to the machine, the upper parts of the bel~s travel in a direction away from the machine 3 over the table, their retul^n parts travelling under the table. The ¦belts 5 Gre driven by one of two rolls 6, 7 ro~atably attached to the ends of the table 4 r and the belts en~age and drive rollers 8, which are rotatably mounted on shafts upstanding from the ~able. When ~he side adge o~ the sheet facing away from the machine 3 touch~s the peripheries of 12~7810 the rollers rotating anti~clockwise in Figure 1, the sheet 1 is moved by these to th left in Figure 1 until the sheet is inserted under the lower part of a conveyor belt 9, dxiven in a suitable manner and carried by a structur~
12 provided with two rolls 10 and 11.
The conveyor belt 9 advances the sheet 1 to the left, the bead 2 being inserted in an upwardly open, elongate slot 13 in a guide rail 14, which is attached to the framework of the apparatus and to the table 4~ The depth of the slot 13 is greater than the height of the bead 2, and the slot has a width at its right-hand end which is rathe.r larger than that of the bead 2 so that the bead can be inserted therein even if the alignment of the sheet on the t~bla is not exact. The slot tapers continuously and at its left-hand end it has a width just gr~ater than that of the bead.
Duriny the travel of the sheet 1 to the le~t, sheet portions on either side of the bead 2 engaging against he upper face of the rail 14, the sheet is therefore aligned exactly by coaction between the rail and the bead, and when the bead relinguishes engagement with the rail 14 the bead and thereby the sheet is accurately oriented relati~e the means, immediately following the rail, for folding the sheet along linss parallel, and close ~o the bead on either side thersof.
Wh~n the left-hand side edge o~ the sheet 1 ha~ left the belt 9, it comes against the peripheries of two folding rollers 15 and 16, which are freely rota~ably mounte~ on shafts 17 and 18 forming an an~le with each other and with the horizontal plane, whereby the portions o~ said side ~L2ff~
sdge on eithGr side of the bead are bent downwards. During its cont~nued travei and folding, the sheet comes into engagement with a ~ed roller 19 mounted on a shaft 22 and driven for rotation by an unillustrated driving means. In coaction with the belt 9 this roller 19 further urges the sheet between the folding rollers and back-up means (see Figure 2 particularly) comprising a roller 20 mount.ed freely rotatable on a shaft 21 and having a width corxesponding to that of the bead. The feed roller 19 urges the por~ion of th~ sheet carryin~ the bead 2 on its opposite side, and thus the bead itself, against the wheel 20, compelling further advance of the sheet for folding between the side surfaces of the w~.eel and the peripheries immediat~ly adjacent there-to of the folding rollers 15 and 16O The sheet 1, ready-folded into a folder with covers a and b and a spine c is best illustrated in Figure 3, rom which it will also be seen that the folding rollexs 15 and 16 may be provided with peripheral hoxizontal surfaces engaging against the ~eed roller 13 for ro~ation o~ the folding rollers duriny the folding sequence, with the object of improving the advance of the sheet through the appaxatusO If so de~ired, the wheel 20 may also be rotated by some suitable device~ The folding rollers may also be spring-biased for pressing against t~he wheel 20 and/or the roller 19~ inter alia for ensuring constant engagement agalnst them.
F~r improving the alignment and guidance o~ the sheet 1 during the folding process itself, the periphery of the wheel 20 may be provid~d with an annular gxoove, the width o~ ~h~c~ corresponds to ~hat of the bead 2, the bead 1~0~
being inserted in this groove whic~ as indicated at 23 in Eigure 2, may have a depth either somewhat less than the thickness of the bead, or somewhat greater than this thick-ness. In the latter case there is obtained the advantage that the sheet 1 will engage against the very thin side walls of the wheel surrounding the groove, said walls defining sharp edges over which the sheet is sffe~tively folded.
Instead of using the wheel 20 as a back-up and guiding means, it may be replaced by the rail 14, which is thereby extended and inserted between the folding rollers ~5 and 16.
For a~.apting the apparatus in accordance wi~h th~
inv~nt.on to diferent bead widths, the wheel 20 and rail 14 are replaceable by wheels and rails of other widths~ A wheel 24 adapted to a greater bead width is shown by dashed lines in ~igure 2. In oxde~ also to adjust the distance between the Eolding rollers 15 and 16 to other bead widths, the support means of at least one o~ ~hese rollers has been adapted displaceable on the shaft 22 and may be locked in any desired position relative the other roller.
When the sheets 1 folded into folders leave the ~olding apparatus, they are counted by a counter ~not shown) disposed in association with the wheel 2Q and stacked into batches, the batches being discharged from the apparatus when they contain a predetermined number of folders.
Even if only a few embodiments of the invention have been described above and illustrated on the drawings, it should be ~nderstood that the invention is no~ lim ~ed to :120~78~0 ~these. Thus, the rail 14 may not be provided with the groove 13, instead being implemented as a thin guide strip against which one side edge of the bead 2 engages during the travel of the sheet 1 towards the ~olding means, or may be replaced by some other suitable means exactly yuiding the bead into the folding means, th~ bead always being exactly oriented on the sheet. The invention is thus solely restricted by what is disclosed in the claims.
