This invention relates to machines for. the manufacture of sheet paper blocks or booklets, e. g. cigarette paper blocks or booklets. V

In such manufacture the purpose generally is to bring a sufficient number of continuous paper bands piled on one anotherall together to a cutting or assembling device whereby the same are made into blocks. Such bands frequently are wrapped in the meantime into anadditional band of stronger paper to serve as a cover, folding of said cover being performed continuously e. g. by means of suitable guides whereby the marginal portions of the band are folded over the other piled up bands to form booklets.

Said bands are fed individually from as many paper reels having a large diameter as compared to their width and they run over guide rollers arranged at suitable heights in order that the bands subsequently may travel as a unitary pile in a common direction up to the cutting or assembling device.

In known machines of this kind the reels are arranged side by side with their axes of rotation parallel to those of the guide rollers and consequently at right angles to the direction of travel of the band pile. The circular faces of the reels then are alined in one plane, which results in excessive overall dimensions of the whole structure inasmuch as the space taken up by the numerous reels is considerably larger than the operative portion of the machine. Moreover, the very importance of such overall dimensions makes watching more difiicult and involves the provision of automatic safety devices.

The purpose of the improvements which are the subject matter of this invention is to obviate such difiiculties. Said improvements consist primarily in arranging the reels in such manner that their axes of rotation are parallel to the direction of travel of the band pile; said axes then are substantially at right angles to those of the guide rollers, so that a twist by an angle of is imparted to each band on its way from the reel to the related guide roller, which twist after all involves no inconveniences. Such arrangement will allow a close grouping of all the reels in parallel relation to one another within a restricted space, whereby the overall dimensions of the machine are decreased and watching the same is facilitated. It is even possible to mount the reels on one common shaft or on parallel shafts, whereby the construction is simplified.

The invention moreover comprises a peculiar arrangement for adjusting the positions of the bands transversely so that they shall come in exact register with one another.

Figures 1 and 2 are a front and a side elevational view of a small gr of reels- Figure 3 illustrates a modification.

Figure 4 shows an adjusting device,

Figures 5 and 6 diagrammatically illustrate the entire structure of a cigarette paper blockmaking machine in a front and a side crosssectional view respectively.

The reels l, of which a considerable number may be provided, are mounted on one common or several alined shafts X and the paperbands 2 supplied from the reels are led while undergoinga twist at an angle of 90 to and over guide rollers 3 the shafts of which are parallel to one another and at right angles to the shafts XX. Said shafts may be arranged at the same height (Figs. 1, 2) or in stepped relation to one another (Fig. 3) depending on whether the bands are to be piledup in contact with or clear from one another.

It is necessary that the edges of the piled up bands should be alined exactly. This result may be obtained by the use of such adjusting means as shown in Fig. 4; the shaft 4 of each guide roller then is carried by a lever 5 rockably mount: ed on a stationary pin 6 and subjected to the action of a spring 1 by which same is pressed against an adjustable abutment 8 arranged in a stationary support 9. By altering the position of said abutment consisting e. g. in a knurled head screw the roller can be tilted slightly upward or downward, which allows easily to adjust the position assumed automatically by the band as the same is running over said roller; in this manner transverse adjustment of the position of the band is obtained without any thrust being exerted on the edges of the latter and consequently without any danger of deterioration.

As shown in Figs. 5 and 6 the reels l are mounted on individual shafts l0 carried in bearings H secured to the frame I2 and said shafts 10 are alined on two horizontal axes XX and XX' above each other, the upper reels being staggered with respect to the lower ones. The paper band 2 fed from each reel runs over and between corresponding rollers l3, M the pins of which are mounted in the frame and arranged in parallel relation to shafts I ll; the band then runs upward and over a roller 15 at the top of the machine the pin of which similarly is parallel to shafts l0 and is carried by a lever I6 mounted in the frame with provision'for adjustment by means of a screw [1.

The bands 2 after they have passed over the rollers ii are guided by rollers IS the pins of which are mounted in the frame at right angles toshafts I0, so that they become twisted by an angle of 90 on their way from rollers l5 to rollers l8. By virtue of the adjustment of the positions of rollers IS with respect to rollers l8 the bands will lay themselves on the latter exactly in register and will remain so without the necessity of providing said rollers with side guide jaws.

The bands as they come off from rollers l8 run over additional rollers I9, 20, the rollers 20 serving to guide or train the bands in reverse direction toward the cut off mechanism at the front of the machine between a pair'of rollers 2|, 22 which arrange the bands in superposed relation, then between a pair of

feed rollers

23, 26 which cause the bands as a whole tojtravel over a table 25 then through a cutting device 26 by which the unitary band pile is divided intoblocks of definite length; said blocks are then taken by additional rollers 21, 28 to an elevating device 29 which lifts the blocks one after the other into a magazine 30 from which they may be taken out easily. Rollers I9, 20, 2|, 22, 23, 24, 21, 28 have their axes parallel to those of rollers [8, i. e. at right angles to the direction of travel of the piled up bands moving toward thecutting' device, whichdirectio'n'in the example shown is horizontal and parallel' to axes XX andX'X: I

Means are diagrammatically illustrated-in Figs. 5 and 6 to provide the piled up bands 2' with a band 3l'folded into two portions and forming a wrapper;- saidband is delivered from a reel 32 ahd-

runsoverrollers

33, 34, 35, 36, 31 before it comes to a guide 33 by means of which it is folded along its median line and to lay itself fiat on the top and the bottom of the grouped bands 2.

Theelevator 29, magazine 30"andwrapping device 32-38 form no part of this invention and need not be described in detail. As to the cutting device 26, this may be of any suitable construction, the cutters thereof being actuated pref erablyin such manner that it will involve no stopping or retardation of the band pile at the time the cutting is performed, e'. g. according to a particular arrangement which provides the subject matter of a separate application.

The arrangements described above by way of non-limitating example are applicable to all machines of the kind referred to that operate either with inlay sheets or with band collection or with band wrapping, etc.; they can be appliedeven immediately after the band-cutting and '-gumming machines for the direct manufacture of blocks without the intermediate step of reeling the paper. As will'be seen by referring to the drawings the several paper strips or webs 2 are'fed from their reels upward over guide rollers l5, having their axes parallel with the axes of the'reels. The strips or webs are then fed downward and trained to travel over other guide rollers l8, 19, which cause them to move rearwardly of the machine. The stripsor webs are then caused to travel about additional guide rollers 20, located at the rear of the machine and these latter rollers cause the strips or webs to then travel forward toward the front of the machine and in theirforward travel they pass between the assembling

rollers

21 and 22, which accurately position the webs or strips in superposed relation so that from that point on the superposed strips or webs travel as a unit toward the front of the machine, where they encounter the cut-off mechanism 21, which severe the traveling unit transversely into separate blocks or sections, which mayor may not have covers applied thereto. When covers are to be applied the cover material is folded about the traveling unit by means of the folding guide 38, located intermediate theopposite ends of the machine.

By this arrangement shown and described wherein the paper webs, after leaving and then reversed and caused totravel longituditheir reels, are "first trained towa.rd-'the rear of the machine duces the length of the machine since the web, assembling, the wrapper supply and the web folding mechanism. as well as the web feeding rolls, may all be located between the front and rear ends of the machine as viewed in Fig. 5, and wherein the

feed rolls

23, 24, may be considered as being located at the front of the machine and the rolls 20 as located at the rear of the machine. Because all the mechanisms referred to are thus grouped within the overall length of the machine,

such mechanisms are more convenient of access by the operator of the machine.
