Device for perforating paper and fabric webs

ο. like

The invention relates to a perforation device, which perforation patterns in webs or sheets Paper / cloth, felt, metal foil and the like, for example in paper webs that are formed with a larger Number of patterns are printed, such as postage stamps and commercial postage stamps.

Rotatable perforation devices, in which the material to be perforated between interacting rotatable male and female rollers carried out is, are in a known manner with PerforationsOrganen provided, which consist of radially protruding perforation pins and corresponding holes, which pick up the pins as the rollers turn. In these devices, a change in the Perforation pattern, for example, from a perforation hole for standard stamps in the larger format of commemorative stamps either the use different perforation devices, which in corresponding Orphan with other perforation pins and -holes are provided, or the exchange of one set of rollers for another, or the removal or additional arrangement of perforation pins on the patrix roll. All of the aforesaid means ^

which the perforation pattern are changed are expensive and time consuming.

In contrast, the invention is based on the task to develop a device for perforation, which makes it possible to selectively different Perforation pattern in the paper web or the like. to incorporate, which between cooperating patrician and Llatrizenwalzen passes without the Rollers or the perforation pins on the perforation roller are exchanged or additionally attached inÜ33en.

This object is achieved according to the invention by There are correspondingly two perforation pins in groups, longer and shorter perforation pins are provided and the center distance of the male and female rollers can be adjusted in two positions in such a way that that in one position all perforation pins and in the other position only the longer perforation pins engage in the holes of the die roll.

This embodiment has the advantage that by simply adjusting one of the two rollers Various patterns or the like can be incorporated into the continuous paper web. While in the a position where only the longer perforation pins come into effect, a corresponding perforation is achieved, this perforation pattern is in the other position, where the shorter perforation pins are also used

to iVirrrun _to -, supplemented or ■ subdivided accordingly. There is, for example, the possibility of combining the lances and shorter perforation pins in groups in such a way that, for the production of stamp blocks or sheets, the effect of all the perforation pins creates a perforation for smaller, normal stamp sizes, and the effect of only the longer perforation pins creates a perforation for larger special stamps Oo Like. Causes.

The known perforation devices also have the Rächte il that an exact match of the holes in the die roller with the corresponding perforation pins of the male roller is not possible. This is mainly due to a restless operation of the device and to a relatively rapid wear and tear of the holes and perforations st if te. These difficulties can also not be eliminated by arranging the perforation pins and matrix whales interchangeably, since precise adjustment, which ensures precise engagement of the perforation pins in the matrix holes, is cumbersome and time-consuming and cannot be carried out in an exact manner at all . Such a precise interaction of the perforation pins and die holes is particularly necessary when the perforation pins penetrate deeply into the die holes for a clean perforation. Such a deep penetration becomes ■ ^: 909887/0196 _, _-. , BATH ORIGINAL

the quality and uniformity of the perforation improved.

According to the invention, this object is achieved by that the die orphan is provided with a jacket support that receives the perforation pins has radial bores, which are covered by a solid film, which when rotating the roller is pierced by the perforation pins.

In this embodiment, the corresponding matrices are only formed in the solid film when the rollers start up created holes, which thus necessarily have an exact position corresponding to the perforation pins. When passing through a paper web ο. like. be this achieves particularly clean perforations.

The holes in the shell support have a larger one Diameter than the perforation pins and the outer surface of the die roll is expedient from a thin metal foil, which is supported by the jacket support and through which the Turn the roller in through the perforation pins butt the holes. Such a metal foil is particularly "suitable" for forming the die holes. It is correspondingly firm and, when the perforation pins are pierced, leads to holes with them match exactly.

909887/0196

The parts particularly exposed to wear, namely the perforation pins and the die sheet, easily exchanged, so that with a small amount of work a new facility can be created quickly and at relatively low cost.

According to the invention, this is achieved in that the jacket support of the die roll and the metal foil consist of matching sections which are releasably attached to the die roll. Each section of the metal foil is removably attached to the associated jacket support. For a new device it is only necessary to remove the relevant sections by loosening the assigned screw connections and to apply a new, imperforate metal foil to the jacket support, e.g. glue it on or the like. Then the die cuts are worked into the metal foil by turning the rollers. Precise adjustment of the perforation pins and / or the jacket supports is not necessary, since the die holes are worked into the initially still imperforate metal foil during the rotation of the rollers. However, this process creates an exact match between the perforation pins and the associated die holes.

909887/0196

The adjustment of the male or female molds against one another can be done in a simple manner according to the invention take place in that one of the two rests in eccentric bearing elements, which are and controls optionally in the two positions is adjustable, which the two workloaders of the rollers. The rotating members for the eccentric bearing elements consist of hydraulic cylinders and a lever system and the controls have two limiting elements of different lengths, which can be optionally inserted into the movement path of the lever system and its movements in the binding positions limit the two working positions. One delimitation element has one Length and position so that it holds the roller in question in the outer position in which only the longer ones Perforation pins come into play, while in the other layer the shorter delimiting element for it Make sure that both rollers are closer together and that the shorter perforation pins also touch the die sheet pierce. By simply adjusting the lever system and actuating the hydraulic cylinder it is therefore possible to determine the two roller layers which are intended for two different perforation patterns.

For the production of normal postage stamps and larger special stamps there is, for example, the possibility that the group of longer perforation pins are arranged in parallel rows across and along the axis

The rotatable perforation device Io is intended for perforation of a web W which is carried by a In the drawing, not shown printing press is fed, which the web with a larger Number of geometric patterns printed, as is the case with postage stamps and commercial postage stamps or the like. Is the case.

The perforation device Io has lateral Frame parts 11 and 12, between which cooperating male and female rollers 13 and 14 are rotatably attached. The printed web W occurs between the side frame parts 11 and 12 the back of the perforation device Io, and leads around a guide roller 15, where the web of a Photoelectric head (not shown in the drawing) can be scanned, which has a control system as described, for example, in US Pat. No. 3,097,844 and by which holds the printed web in a precise locking position with respect to the perforation pins which are arranged on the male roller 13. The web W follows from the guide roller 15 at the top between the rollers 16 of a lateral tensioning device 17 which, according to US Pat 3 147898 can be executed and by which the web is smoothed laterally and tensioned before it is guided around the die roller 14 * The web is in a non-sliding way

A rubber-covered roller 18 is provided for this purpose provided, which ._- in lever arms 19 ._- which protrude from a shaft 2o on their Ends in the side frame parts 11 and 12 is stored. The free ends of the lever arms 19 are rotatably connected at 21 to cylinder pistons 22, which form a hydraulic cylinder 23 which is supported by supports 24 which run between the side frame parts Adjustable screws 25 lead through a carrier 26 via dfe.u lever arms 19 and allow an adjustable Limitation of the vertical reciprocating movements of the lever arms 19 when compressed air or a pressure fluid acts on the cylinders 23, to the pressure of the RAe η 18 against the Adjust the dumbbell of the die roller 14.

The web W leads from the roller 18 downwards a guide roller 27 (Figure 1) and is continued after discharged backwards to a next working unit, for example a device which is the continuous Cuts the web into individual sections.

The rotatable perforation device Io is preferably driven synchronously either with the working units located in front of or behind it via a vertical drive shaft 28 which has a spindle 29 which cooperates with a pinion 3o which is mounted on a bath of a transverse shaft mounted in the side frame parts 11 and 12 909887/0196

"is attached. The one opposite the pinion 3o End of the shaft 31 carries a gear 32 which is in a Gear 33 arranged on the die roller 14 engages and, during rotation, with a gear 34 cooperates, which is assigned to the male mold roller 13 (Figure 2). The gear 34 i3t of such a design that it takes up any play between the gears 33 and 34, for example as described in US Pat. No. 2,911,847, to rotate rollers 13 and 14 in a precise manner Angulation or haste when changing the distance between the roller axes or one Change the contours of the gear teeth due to wear and tear.

The male roller 13 comprises a cylindrical housing 35 and end plates 36 which are attached to each other opposite Endea. of the housing 35 screwed on or otherwise attached and which carry axial shafts 37 which protrude outward. These MJ.en 37 are rotatable in bearings 38 supported, which are carried by eccentric bearing elements 39, which are in the lateral track parts 11 and 12 run. As Figure 3 shows, has each eccentric bearing element 39 has an arm 4o, which protrudes radially and at 41 articulated with a End of a lever 42 is connected, whose sauleras End rotatably connected at 43 to an arm 44, which is supported on a transverse shaft 45, which at most

909887/0196

rotatable in the side frame parts 11 and 12 is stored. The shaft 45 is rotatable by means of the arms 46 attached to it, which next to the lateral Parts of the tap are located and rotatable at 47 are each connected to a fork 48, which of the piston rods 49 of a hydraulic cylinder 5ο be worn (Figures 2 and 3). The hydraulic Cylinders 5o are held by brackets 51 attached to opposite sides of the frame are. When compressed air or another pressure fluid acts on the cylinder 5o, the piston rod 49 is either retracted or pushed out, so that the shaft 45 rotates and over the lever system between shaft 45 and the eccentric bearing elements 39, the latter are rotated and the male roller 13 is displaced relative to the female roller 14 is, whereby the distance between the axes of the rollers increases or decreases.

As can be seen in particular from Figures 4 and 6, the patrix roller 13 still has elongated, in cross-section curved pin holding plates 52, the rest on the surface area of the housing 35. The plates 52 are axial to the cylinder 13 and can, for example, be about half the length of the roll have appropriate length, so that two plates 52 lying next to each other on the surface of the housing are arranged as shown in FIG. 6. The width of each plate 52 corresponds to a fracture construction 90988770198,

156H91

part of the circumference of the housing 35, so that several Plates 52 can be arranged edge to edge around the housing. Each plate 52 is means Bolt 53 is detachably attached to the housing 35 and is precise by means of dowel pins 55 on the housing held in position (Figure 4).

The plates 52 have holes 55 (Pigu.'r?) provided, which are arranged according to the perforation pattern to be formed and the narrow The area of each hole 55 is under extension to 56 counter-drilled.

The bores 55 of each plate 52 take perforation pins on, which according to the invention from groups of relatively long perforation pins 57a and 57b and groups of relatively shorter perforation pins 57c exist (Figures 4 and 6-9) · each Perforation pin has a head 58 at its inner end, which is in the enlarged counterbore is held. Thus, when all plates 52 are arranged on the housing 35, perforation pins 57a protrude 57b and 57c through the respective bores 55 radially outwards and are by means of their heads ^ J held in place, dealing with her

Head surface on the lateral surface of the housing 35

Support ~ -3 · As shown in Figures 6 to 9 the longer perforation pins are 57a and σ> 57b held in each plate 52 so that this protrude further beyond the outer panel surface than the shorter perforation pins 57c.

156U91

When using the perforation device for perforating postage stamps or commercial postage stamps in two different sizes, for example a smaller, normal letter size and a larger memory stamp, the longer perforation pins 57a and 57b are at a certain distance in groups or rows around the jacket of the Male roller B and at a certain distance in rows transversely to this, ie arranged axially on the jacket. The relatively shorter perforation pins 57c are arranged in parallel rows between the rows of the longer perforation pins 57b. The spacing of the rows of Perforationsstifte 57a -and 57b and 57c is such that when all Perforationsstifte to the web W to act, the obtained Perforationsmusterung 59 ^a "59b and 59c (FIG Io) in the paper web W o. The like. A normal postage stamp size if only the longer pins 57a and 57b act in a perforating manner on the web W, the perforation pattern 59 * a and 59 »b (FIG. 11) corresponds to the size of memory marks or the like. The width of each plate 52 is preferably dimensioned in the direction of the web W such that a larger number of standard postage stamps are perforated. As shown in Figure 6, the axially directed rows of perforation pins 57b and 57c on each plate 52 are one or more undivided for perforation Standard postage stamps, for example three

undivided standard postage stamps , and a half 909887/0196

Standard postage stamps on each long edge of the panel arranged. The rows of perforation pins 57a running around the lateral surface and facing the inner The edge of the plate 52 are so far back

yeine set that both adjacent. Half a plate Record standard postage stamp width. Thus, despite the assignment of the perforation pins to different Perforation patterns to be individually fastened to the housing 35 plates 52 arise, which also in the area the panel edges are not interrupted.

The die roll 14 has perforation holes (FIGS. 4, 5 and 8) which, when the of the rollers 13, 14 pick up all of the perforation pins 57a, 57b and 57c.

Due to the radial arrangement of the patrix roller 13 relative to the cylinder 1 # in the position shown in Figure 7, all perforation pins 57a, 57b and 57c engage in the corresponding perforation holes 6ο of the die roller 14 when rolling, with a perforation pattern, for example for standard postage stamps, when passing through a paper web W arises as Figure Io shows. Wi * rd, the forming roll 13, but radially from the matrix-bearing cylinder 14 in the vorbeschriehenen type lifted, so that a relative Ia-ge entfc ^1: Ht, as shown in Figure 8, where only the longer Perforationsstifte 57a and 57b in due ^ correspondence

the perforation holes 6o come into effect,

909887/0196 BAD ORiGlNAL

a different perforation pattern arises, for example for larger special stamps, as shown in Figure 11.

Although the perforation patterning in the web in the exemplary embodiment is shown in FIGS corresponds, it is obvious to arrange the hole patterns by other arrangements of the larger and shorter ones To vary the perforation pins on the patrix roller.

Around the two layers of the rollers 13 and 14 for an optional formation of one or the other hole pattern has to be determined by the perforation release device Io a control shaft 61 (cf. FIGS. 2 and 3), which protrudes slightly on the lateral

Rahia parts 11 and 12 is attached so that their Ends under the forks 4δ, which are arranged at the lower ends of the piston rods 49. On each of the two shaft ends there are two radially protruding, arranged at right angles to one another Limiting elements 62, 63 of different radial dimensions, which can optionally be in the downward directed trajectory of the adjacent forks 48 when rotating the shaft 61 can be engaged. One end of the control shaft 61 has a crank arm 64 by which it can be rotated manually, wherein the crank 64 carries a spring-loaded locking element 65 (see FIG. 2) which can be detached in one of the two holes 66a and 66b engages (cf. Figure 3) on the adjacent side of the carrier

frame 12 are provided. The locking pin engages 65 into the hole 66a (FIG. 3), the delimiting elements 62 lie under the forks 48 and limit the downward movement and determine when the hydraulic cylinder 5o is attached the working position of the rollers 13, 14 according to Figure 7, with all perforation pins in the Engage perforation holes. The hole 66b, however, is arranged so that the limiting elements 63 after a corresponding rotation of the control shaft 61 in the path of movement of the forks 48 and the working position of the rollers 13, 14 accordingly Limit Figure 8, with only the longer perforation pins engaging in the shaped holes and the shorter pins remain above the surface of the die roll 14 so that the passed through Web W cannot be acted upon by the shorter pins.

In the position shown in FIG. 3, the control shaft 61 determines the working position of the Rollers 13 and 14 for perforating the smaller standard stamps and for turning them into the position where the limiting element 63 is directed upwards, the working position for the perforation

of larger special postage stamps. This change for the perforation patterning can be carried out very quickly without having to replace the perforation pins or the perforation roller. 909887/0196

A plague hanging of the web W on one of the perforation pins to prevent retraction from their perforation holes are compressible Plastic cushion 67 (Figures 4 and 6) made of rubber or the like. On the outer surfaces of the Plates 52 glued between the rows of perforation pins 57a, 57b and 57c. These pillows 67 are preferably arranged in a chessboard-like division, as shown in FIG so that a small number is required to attach them along the rows of pins. The thickness of the plastic pad 67 is slightly greater than the distance between the outer surfaces of the Plates 52 and the peripheral surface of the die roll 14 in all working positions according to the FIGS. 7 and 8. Thus, in both working positions, each cushion 67 is acted upon as it passes through the Hatrizenwr '^ e 14 compressed, and bein If it runs off, it expands back to its original thickness and pushes the web away from the neighboring ones Perforation pins

As shown in Figure 2, the die roll 14 preferably has the same effective outer diameter chme as he like the patrix roll 13 and includes also a body consisting of a cylindrical housing 68 and end plates 69 which are attached to the Ends of the housing are arranged and axial stub shafts 7o, which protrude outwards and are rotatably held in bearings in the lateral Frame part «! 11 and 12 are arranged. the

The die roller 14 also has a ring carrier 71, which iat divided into corresponding segments or sections that are curved in cross-section and bear against the outer surface of the housing 68 (Figures 4 and 7-9). Tuck sections of the jacket carrier 71 can have dimensions which are those of the perforation pins supporting plates 52 correspond and are individually on the housing 68 by means of bolts 72 and Dowel pins 73 arranged (Figure 4).

According to the invention, the jacket carrier 71 hfct radial Bores 74 in accordance with the perforation pins 57a, 57b and 57c in the Rotation of the rollers 13 and 14 are arranged. These bores 74 preferably have a larger one Diameter than the perforation pins so that they can easily accommodate the latter when the pins are in penetrate the holes 6o as soon as they have pierced a solid film 75 on the outer Surface of each carrier section is arranged. The film 75 can, for example, consist of a thin stainless or blue tempered spring steel are made, which by gluing, soldering or the like. at least in the region of the bores 74 removably arranged on the outer surface of each carrier unit is. The film 75 can be applied to any carrier have essentially the same dimensions, so that when the carrier parts are mounted a uniform outer surface of the die cloud 14 form. 909887/0196

First of all, the film 75 on each section 71 is imperforate at the locations of the bores 74, as shown in FIG. It is supported by the perforation pins 57a, 57b and 57c, which preferably have hardened heads for this purpose.

According to the invention, the carrier sections Foils 75 which are imperforate in the area of the bores 74. These beam sections are attached to the die roll 14. The Patrizenwalae 13 is in the working position according to FIG 7 brought so that when the rollers 13 and 14 rotate, all of the perforation pins 57a, 57b and 57c penetrate and pierce the film 75 and perforate holes 6o that exactly match the perforation pins. Since the perforation holes in the film 75 are not preformed, but rather from the perforation pins after the support sections have been attached to the body the die roll 14 are formed, there is none Need to be accurate or compensatory Adjustment of the carrier sections when they are attached to the roller. The oversized ones Bores 74 ensure that the perforation pins pierce the foils 75 and into them penetrate without disadvantage, even if a compensatory adjustment of the carrier sections is missing.

Furthermore, the enlarged bores 74 allow the metal ejected from the foil 75 through the perforation pins to pass freely through them into the undercut peripheral parts of the windows 77 of each carrier section 71 arrive (Figure 4). If the foils 75 coincide with each carrier section 71, this is still provided with windows 78 (FIG. 5) which correspond to the windows 77 of the carrier sections. Because the windows 77 and 78 run along the bottom of the cylinder 14, it falls out of the film 75 ejected metal through the window and is thereby removed from the die roll 14.

After the perforation holes 16 are formed in the film 75 by the perforation pins, the device Io is ready to perforate a web W. The web is first around the die roll 14, the rollers being in the position according to FIG. Then the hydraulic cylinder 23 is applied so that the roller 18, the web W against the lateral surface of the Die roll presses and it does not slide on it. Finally, while the device is running

The ejected particles from the web fall through the bores 74 into the lower windows 77 of the carrier sections.

In order to facilitate the removal of these particles from the pen stars 77 at the bottom of the cylinder 14, some parallel tubes 79 (FIG. 1) lie axially under the die roll 14 and have recesses or upwardly open pipe sockets through which an air flow to the perforation holes 6o, Bores 74 and windows 77 and 78 is directed to to remove the particles accumulated in it. The tubes 79 are attached to the side walls of a chamber 8o worn, which has an opening on the head which engages the lower jacket part of the die roller 14 below. The pipes 79 are provided with a manifold 81, from which a branch 82 to a Compressed air generator leads. The interior of the chamber 8o is connected to a suction system at 83 (Figure 2), so that the air-blown particles are sucked into the chamber 8o.

When perforation pins are worn or damaged, the relevant plate 52 carrying these pins is removed from the cylinder 13 and the damaged or worn pins are replaced. When each plate 52 is fastened again on the housing 35 of the male mold roller 13 at the intended location by means of the dowel pins 54, the replaced perforation pins exactly match the relevant perforation holes 6o of the die cylinder. When one of the perforation holes bo is worn, the relevant carrier section is removed from the die roller 14 and replaced by another section 71 which has an imperforate film. The procedure described above for forming the perforation holes 7o is then repeated, these being worked into the film and exactly matching the associated perforation pins from which they are formed. From the carrier

the perforation pins of the male roller 13 are made, is particularly in the case advantageous where an optional perforation of various perforation patterns is provided in the web is. In such a perforating device, the longer pins 57a and 57b accordingly penetrate deeper into the holes in question when the rollers 13 and 14 in a the work position corresponding to FIG. 7, so that all perforation pins interact with the perforation holes. Because the film is 75 thin ■ and the holes 74 of the die support gfößer than the pins are, the longer pins 57a and 57b can penetrate obliquely into the bores 74, because the perforation pins move the roller 13 with a relatively larger angle of rotation will.

However, the described arrangement and procedure, by which the perforation holes 6o in the die roller are brought into precise correspondence with the perforation pins of the male roller, can also be used for any other rotating perforation device, for example for those which only have one row of perforations in the train should form. In all cases, the precise interaction of the perforation holes with the perforation pins allows a smooth working process and a deep penetration of the pins 909887/0196
