Device for distributing and simultaneously cutting rolled up strips of material

Ea are the priorities from the French patent application No. 72 15588 of April 27, 1972, its 1st additional application No. 72 29761 of August 16, 1972 and 2nd additional registration 72 4-7 127 of December 26, 1972.

The invention has means of dispensing and simultaneous Cutting of rolled up material strips to the object.

The subject matter of the invention relates to the technical fields of handling flat and in strips Materials, as well as on toilet or packing accessories.

Various means, devices or apparatus are proposed has been used to dispense regularly fragmented materials present in tapes, especially dispensers of Toilet paper, bags, handkerchiefs, disposable napkins, foils made of aluminum or tea-like or non-textile-like Materials have been proposed.

In general, these dispensers or dispensers are loaded with either simple or pre-cut rolls of material, which one unrolls, and which one only manually or with the help of a simple device (for example by means of a toothed Edge edge) chopped up to the desired length, or they are filled with layered basins of materials, which are separated from each other sheet by sheet, and which are so

pulls out more or less orderly.

In the case of dispensing bags, envelopes or clad Scrolling, the material lengths are separated either by tearing them off (serrated edge) or with the help of one of the donor-independent cutting device or tool (Hesser, Chisel, frayed blade).

It is known that these various gowns have significant disadvantages and, in particular, are difficult to separate accurately is to be effected satisfactorily or occurs irregularly and may require a certain amount of tedious handling. In addition, the rolls, tapes or packs of material must be pre-cut, cut off or appropriately stacked which increases their cost price.

According to the invention it was intended to provide a device for distributing pieces of rolled haterials, consequently this in a well-ordered, quick and effective manner and way no longer by tearing it off Apparatus, still by separate manual or mechanical cutting, but by cutting simultaneously with the Dealing happens.

The device according to the invention has sum characteristics that they has a roller carrier which is articulated to a drum, which by simply pulling manually on the free, over the Material end emerging from the edge of the apparatus is driven to rotate by friction; that at the end of the draw a cutting device which has a fixed part that is adjustable in its position and a movable part has that the material progressively over its entire width, acting like a knife, cuts off, and that after Cut a new ribbon by positioning the drum protrudes over the edge of the device.

According to a first embodiment variant, a programmed Regulation of the distributed and cut length of material by temporarily removing the cut or cut counterblade when pulling the over the edge of the

Apparatus protruding material band provided. With this design, the cutting blade is independent of the rubbing drum, and is driven by a push finger as it passes the counterblade and while the material is being pulled, which is positively connected to a transmission organ that works with the drum. Another distinguishing feature is that you can measure the length of the material to be cut off in a fork involved in this process by means of a device for varying the drive ratios the drum in the form of conical or, for example, expandable pulleys, one of which on the axis of rotation the drum is wedged, can be changed.

According to a second variant embodiment, on the one hand, they are movable on the material drive drum, on the other hand on one Fixed support provided organs that allow the cutting of the extracted material and in absolute terms safely prohibit the cutting of a second strip of material after the same pull. The whole, from one Stand-enclosed cutting mechanism is attached to the bottom of the housing in such a way that it can be quickly and easily can be easily dismantled from the main body. Another distinguishing feature relates to the assembly of the material .. roller carrier comprising a roller centering device which has an articulated arm which facilitates changing of the reel and is in a spaced position with respect to the housing can be withheld.

Following another distinguishing feature is the roll of material for the purpose of freely handing any length of material out of the drive drum by a swivel system removed, which can be actuated from the outside of the housing and acts directly on the roll of material,

These and other distinguishing features are evident from the following Description.

In order to further concretise the subject matter of the invention, it will be described below in a non-restrictive manner, Described in the figures of the drawings form shown.

Assuming that the distribution and according to the invention Although cutting device is intended to refer to any type of rolled material, an apparatus is described below, designed to cut ribbons into napkins made of plain or coated paper are to be distributed in private or collective sanitary places.

The device can be offered in several different forms: As furniture standing on feet, as a cupboard, as a wall lock or as with a reception table or another Facility positively connected.

In the present case, the design is considered in more detail in the form of the wall block, which is formed by a mounting plate Λ

will that on the wall or wall on some known Wexbo, for example by means of eye bolts, shafts or Screws attached to openings 1a in the plate work together.

The plate 1 has articulation members on one of its sides, such as Hinges 2 for a cover screw 5, which is of such a contour that they comfortably fit the internal mechanisms can take up.

This cover screw can be opened in different ways, be it from top to bottom (hinge on the lower Part of the plate), be it from the bottom up, be it in a preferred way laterally (IPig.1), which makes keeping it open unnecessary makes and avoids the risk of injuries in Ealle of their loosening or detachment in the course of the operations.

Since, as can be seen from the following, the paper roll only engages on one side, so the hinge must be on the side opposite this side, because the contour of the cover screw prevents it from opening to 180 (Appendix e; egen the wall).

A closure member is located between the cover screw and the mounting plate intended. For example, a hook lock 4 can be attached, which can be actuated by means of a key 5 and cooperates with a finger 6 of the plate.

On the mounting plate 1, a U-shaped support 7 is attached in any known manner, the arms of which a. Take up drum 8 freely rotatable.

This drum is not circular over its entire circumference,

but points, following an opening 8a, along its entire length

or surface line arranged, a blade or small rod

whose outer edge is located at a distance greater than the radius of the drum.

This blade is attached to the drum at its central part by means of screws, while its ends remain free (Fig. 4-), for the reasons given below

309845/0416

- 8 - 2318358

can spring through. In addition, rings 11 made of an elastomer or nylon are inserted between the blade and the drum, to dampen the noise (Fig. 8).

The blade 9 acts on a PurJfc the drum rotation with a Counterblade 12 together, which is attached at both ends to transverse struts 1'5, which for their part on angled Branches 7 & of the support 7 are fastened.

The counterblade 12 of rectangular cross-section is arranged in a special way. At first it rests in an oblique position Position on the cross struts 13 (Fig. 8) so that the edge the blade 9 following a line and does not come to the contact system on its entire front side of the cutting edge. on the other hand the counter blade has an inclined position over its length in the horizontal and vertical plane (Fig. 4 and 6), and that is why, so that the cutting of the paper starts from the edge of the iQüige 9 when the drum is rotated beforehand progressively towards the other edge, i.e. in the manner of a pulling knife.

Around. the precise action of the blade 9 with regard to correct cutting and without stressing the paper to be sparged To facilitate this, various equipment is provided. The end. F.ig.8 it can be seen first that the counter blade 12 in adjustable VJeiae on the clamps 7 & with the help of elongated hole openings 7b and. of locking screws interacting with these 14 is attached. Another setting concerns the height of the blade 9 with respect to the counter blade Changing the thickness of the noise-dampening rings 11. Finally, the attack end of the blade 9 has a rounded portion 9a (FIG. 9 and FIG 10), which make clamping easier, and complete the side springs of the blade 9 and a central spring the counterblade allowing assembly of these adjustments.

A deflector plate 15 is attached to the anvil blade 12 in order to prevent the unrolled paper from running over the anvil blade. _

The paper roll R is placed on a transverse support, constituted, for example, by an axle 16 carried by an arm 17 attached at 18 to this mounting plate 1 is hinged. Close to this arm is a hanging or take-up reel carrier made, for example, of nylon 19 arranged, which can rotate freely on the axis, but cannot shift lengthways. This ring at least shows two receiving devices 19a with elastic properties, the firm application and retention of the take-up reel or allow hub B of the paper roll that comes to rest against a shoulder 19b of the ring (FIG. 5).

Preferably, although not limiting the invention, in order not to be mistaken in the sense of clamping the roller, provided, the take-up reels B closed at their end B.

ρ and provided only with a small opening B with a large inner inlet, in which a conical, inserting cylindrical or otherwise shaped part 16a formed at the end of the axle.

On the other side of arm 1? the axis 16 extends laterally further out to form a groove 16b which receives elastic means, such as an elastomeric belt 20, which is wrapped around a corresponding groove 21a, which is formed on a finger 21, which extends as such at the end of a Swing arm or eccentric 22 is located, which is angularly wedged on the axis of rotation of the drum 8 (Fig. 6). The angular position of the eccentric is calculated in such a way that the rotation of the drum is controlled, i.e. braked when pulling and after Cut through- the effectiveness of the belt is accelerated.

The connection paper roll / drum through this elastic means with an eccentric or swing arm allows. Returning the drum to the rest position, ie. in the position after Handing out a ribbon. However, it cannot be ruled out that the elastic return may cease to exist, namely if precise balancing by means of a regulating weight

or the like. fulfills the same functions, i.e. the slight but braked rotation of the drum when pulling on the paper as well as the rapid, accelerated return to the rest position after a cut of the paper allows.

The following is now the handling of the invention Distributing and cutting device described.

After the paper roll is in a fitting manner on its take-up spool support has been brought into position, one unrolls a piece of paper from the roll so that it over the slot 3ä the cover hood extends out in a length that is sufficient now easy to grasp by hand. At this time the blade fl carried by the drum 8 rests on a stop 23 (Sig.J and 7), which is attached to the mounting plate 1 is. This stop only has to hold the drum back after it has passed on the latter. For this purpose, various forms of stops and, for example, a retractable stake are provided. In this version you can see a ring 23a made of plastic material, which is attached to a support 23b, the front end 23c of which is directed upwards in order to limit the deflection of the ring.

By simply pulling the end of the paper protruding from the side this is supported on a wide section of the drum, and displaces this without sliding due to sticking of the Paper on its surface, which is equipped with an anti-slip material 24 · (rubber, emery cloth, grains, etc.) is in rotation.

At the end of the drawing, the blade 9 comes with the counter blade in contact, thereby lifting the paper up and clamping it. The progressive cutting takes place, and so does the user Finally holds the correctly cut ribbon in his hands, and while the under the pulling and under the tension of the Belt started drum continues to turn, blade goes. 9 past the stop 23 and then comes there to a standstill, because the drum is driven by the action of the

- $ 1 - ■ 309845/0416

Belt and stop, which is equally swaying prevented, slowed down at rest.

At this point the paper tape is over the edge reaching out, ready, for the distribution and the simultaneous cutting of a new section of tape like that first to be pulled out.

As can be easily understood, this is the length of the truncated The tape is a function of the diameter of the drum and the number of tapes is a function of the diameter of the roll of paper.

A device is also provided for counting the bands for easy replenishment thanks to a simple, visual control and without having to open the device. Such a device is devoid of the invention to want to limit the following.

A small plate 25, which is attached to the end of the arm 17, is attached in a suitable place, the engraved, glued on or otherwise produced lettering on it Plate from the outside through an opening 3b in the cover are clearly legible through it, which for this purpose with a magnifying Magnifying glass 26 can be provided. The labels can be of any kind of order by, for example consecutively from top to bottom with the digits 50 - 10 - 0, corresponding to the number of blended bands, that remain to be distributed are labeled Apply marks 1/1, 1/2, 0.

It can be understood that the plate 25 is the reduction Marks corresponding to the role can only be seen through the opening in the cover.

As already said above, the device according to the invention also offer under other forms than that of a jack buck.

In Figure 11, for example, a cabinet 27 is shown, the opens laterally, with its upper part the cover

309845/0416

with slot 27a forms, while its middle ;, less wide part 27b inwardly carries stand that accommodate several paper rolls R in the supply. On the lower part can be a swiveling garbage can 27c be set up to the used Collect napkins.

Finally, you can have a supply of .Material rolls (Paper, elastic, fabrics) that can be used directly and in regularly have glues, welds or seams in such a way that bags are cut off immediately In this case, care will have to be taken to ensure that the reel is in position on its carrier of the unwinding coil brought or indexed so that the cut is effected just behind the bottom of the bag.

In a first form of the execution variant, as it is in the 12 to 16 of the drawings, the apparatus essentially comprises a U, for example bent sheet metal existing frame 28 on which a profile iron 28a protrudes, which has a handle for transport or hanging on wall hooks forms "

Feet 29 are detachable under the frame attached to the floor, which, curved, at their cranking point with serving for attachment to the frame Tabs 29b are positively connected.

In the event of hanging on the wall, it is necessary to to distance the apparatus from the wall, so that the inserted role of the material to be distributed and cut does not is present.

For this purpose, fastening tabs are used, for example, in two levels provided through which a hole is drilled for fastening with screws. The plane perpendicular to the mounting plane serves at the same time for positioning support (Fig ^ 12 and 14).

The removable attachment can also be used in other design variants, as described below come. - 15 _

309845/0416

- 2318358

The legs of the frame, free in slideways 28b, take the overlooked axes of the roll of the material to be dispensed on, which moves vertically downwards and thus constantly moves with the drive drum, which is provided with a rough clothing 30 is in contact system and the, radially via a Mante-l line protruding, at the same time carrying the cutting blade J1, as described for the previous embodiment became.

The counterblade 32 is always mounted at an angle with respect to the other blade on its support 33 in such a way that that they progressively over the material as the drum rotates cuts its entire length, but its fastening tabs on the support 33 'force it into their plane to wind upwards in order to be more precise at the moment of the cut. Counterblade to follow (feature 15)

The support 33 is hinged to the legs of the frame and is supported by a strong return spring 34 or something similar Means against a stop 28c of the frame (Figure 13) held in position to make her jump back Prevent time of cutting.

In this embodiment, it is possible to vary the length of the material to be dispensed through the cut. For this purpose, a transmission member, for example a gear 35 is provided at the end of the drum, which directly or cooperates with another gearwheel 36 by means of a chain, axed onto the stop 28c, for example of the frame is. This second wheel carries a roller 37j on its circumference, which is caused by the rotation of the wheel 36 the train on the material (drive of the drum so the wheel 35), can come to that that they against a retractable peg 38 abuts ?, which, arranged on a support 39, is positively connected to the support of the counterblade, and so the counterblade eliminated at the moment of passing the blade (I'ig.13).

In general, one will change the length from single to double by using a wheel 35

309845/0416 '" ^m "

effect, which has twice fewer teeth than the wheel 36, which allows the roller 37, while the drum two revolutions makes to run into the stake only once. It goes without saying that one can just as well have gear ratio wheels 1/3, 1/4 can use whatever allows, single, double, triple length materials, etc., for output to let come.

The attachment of the retractable stake can be done in various ways and, for example, as shown in FIG. done by a button 4ü, which is connected to the stake and crosses a passage of the support, and which one unscrewed to allow the stake to slide smoothly, or it can be moved by elastic positioning in the with two grooves 39b provided passage take place, the cylindrical bearing points 38a of the peg receive (Fig.16). The stake is slidably guided by an axis 41 which extends from the extension 33a of the support of the counterblade will be carried.

The locking stop of the drum is shown in this embodiment held in the section, but is, as is shown in FIGS. 12, 14. 15 and 15 show arranged laterally. Recognizes in these figures one set of 30s. the drum that designed so appropriately is that when the tension exerted by eccentric 43 and its belt becomes zero, it is free against one of the frame hinged web 42, pushing it back, happens and leans there. The web is when it is out of the stop position has come back, fixed by some elastic means 45 to the support 33 äer counterblade.

In order to be able to easily insert the material strip of a new roll between the drum and the counterblade, provision is also made for the spacing of the counterblade to be brought about by hand independently of the roller / peg unit. For example, in FIGS. 12, 13 and 15 a lever 46 can be seen which is hinged to the frame and has a bevel 46 _a for cooperation with another complementary bevel 33 b which is formed on the support of the counterblade.

309845/0416

If you exert a pressure on the lever 46, the support 33 migrates as a result of the cooperation of the slopes. A lock in the emigrated position can be provided.

It can also be seen that this device is the application of a selected, independent of the setting by the stake Material length may allow.

According to another embodiment shown in FIGS. 17 and 18, the dispensing and cutting device has a. Material roll carrier 47, which is articulated to a base plate 48 - the drive drum 49 is in a U-profile 50 axially, which is positively connected to the plate.

The cutting blade 51 is here independent of the drum, i. E. at sector 52, coaxial with the drum, but with respect to this freely rotatable attached. Like the drum, the sector is provided with a rough surface covering in order to drive it by pulling on the strip of material reaching out over the edge of the apparatus.

The rotary drive of the sector, that is to say the blade, takes place during pulling by means of cogwheels or similar means, one of which, "53", is keyed onto the drum axis, while the other, "54", is axled onto the profile 50, where a purpose-sized finger 55 there can be angular.

With this mechanism, if you pull on the strip of material, you drive the drum and continue to drive the toothed wheel 53, the wheel 54 whose finger 55, which then hits the roller 56, causes the sector 52 to turn which leads to the fact that it passes under the roll of material and is driven in part by the train until the blade 51 passes the counterblade 57, thereby cutting off the material. The sector, which is connected to the drive eccentric 58 on one side and is then quickly sent back, as well as the blade come to the already described «» *

309845/0416 ~ ^Λξ> ~

- ie - 2318358

Positioning stop 59 to the plant.

The counter blade 57 is on the legs 50a of the profile 50 mounted at an incline and equipped with a deflector plate 61 to guide the unrolling material.

Other means can also be provided for setting the material lengths to be dispensed, such as embodiments in FIG Figures 19 ″ to 21 are shown.

For example, instead of the gears, a two-part belt pulley 62 can be used on the drum axis on the one hand two disc parts facing each other coaxially in the front, of variable distance and on the other hand on one axis which is positively connected to the support 64 of the drum, attach another pulley 65 of the same type, which are connected to one another by a V-belt 66. In this case, a suitable medium can be used to determine the drive transmission ratio, i.e. the length of the cut material it vary.

The device can be controlled, for example, by means of a swing arm 67 which, with respect to a fixed point of the apparatus (base plate, drum support ....) is rotatably mounted and at both ends of which sleeves 68 are articulated, which are on the axes of the pulleys, on the im Return springs acting to increase the mutual distance between the individual associated pulley parts act. A handling lever is positively connected to the swing arm and extends laterally over the edge of the Apparatus where a scale 70 of some kind is provided can be in order to be able to recognize the length of the cut material in every position.

In FIGS. 21 and 22, a control device is shown in which instead of the belt pulleys with removable pulleys Disc parts provided with inversely conical discs 71,72 connected by a belt 73, of which Running point changed by a fork 74 with friction rollers 74-a can be and which, attached to a support 75, in relation

309845/0416 "

on a tab 76, which is positively connected to the 'drum is, for example in grooves 76a, 76b and by means of a guide finger 77 can move. The groove 76a that of a handling lever 7 ^ -b is traversed, limits the fork movement.

Line divisions marked on the tab 76 above the groove 76a check the selected cutting length.

It is not excluded that for certain applications manual pulling by some motorized drive the drum is replaced in order to deliver a series of cut strips of material (in the weaving mill, for example) obtain.

Other options for dispensing and cutting the tape are available starting from the basic device. So can for example, as shown schematically in Fig. 25 is led, bands of bellows-like stored materials by placing them in a magazine 78 with a stores the material stack only partially restrained bottom 78a, wherein the drum with the cutting blade is arranged at the level of the recessed floor. By pulling on As the material protrudes over the edge, the folded lengths roll off and easily emerge from the drum.

There can also be two or more devices of the first embodiment or their variant, one acting independently of the other, put them next to each other and put them in flight or arrange them one above the other. This method allows it is possible to get by with less frequent reloading of material. If you build with an invulnerable as a precaution Fitting a closure on one assembly and attaching a closure on the other at the opening where the material exits, you can be sure of a successor machine that is always fully stored and ready for use.

This apparatus mapping is especially valuable when it comes to is about dispensing toilet paper in common areas.

On this occasion it should be noted that the paper generally used is of a material quality which does not provide all the necessary guarantees of good driving through the drum, and it happens that the interface does not protrude sufficiently beyond the edge of the device to be comfortably graspable. To remedy this deficiency is for this is provided with a partial cut of the paper, i.e. that after the cut, a small part that has not been cut is allowed to persist beyond the edge, which easily when pulled can be separated, but on the one hand the guidance of the paper and on the other hand the error-free drive of the belt, following the cut, allowed.

In this case one deforms the counter blade or the blade so to speak that it does not cover the whole of the paper Width cuts, and effects a precisely necessary blade display by means of slightly oval fasteners the blade or counter blade.

In order to satisfy certain users, a device for printing on the distributed material (for example for Butchers, pork merchants ...). For this purpose one equips the apparatus with a color block, who works with a relief engraving based on the The drum is mounted in a position that is intended to mark the paper that has been discharged. For example, in 24 a conventional color block 79 can be seen, which is elastic (by Eedern or elastic washers) by means of screws or, especially in the embodiment according to F.ig.i2, Is attached by means of the frame 28 so that it is constantly in contact with a cliché 80, dos on the drum 3 ^> is glued on or otherwise attached to this.

When passing under the applied paper, the cliché prints the lettering it bears by pressing it, without hindering the process.

It is now 4. of interest, the maximum of paper output to limit to prevent any waste. That is true

309845/0416

especially for distributors installed in common areas are.

With the device according to the invention - and this also applies to all variants - you need what the simultaneous and automatic dispensing and cutting of the paper, absolutely not to insure this limitation, since the fact to be forced, a separate piece after each Pulling out a cut already has a limitation.

The problem is, the mechanism after an initial application to block and to release it with an additional actuation.

For this purpose it is provided on the one hand to manually operate the drum to be driven by a crank, handwheel or other similar means and, on the other hand, this drum in position after the distribution and cutting of a piece of paper and to block it by a drive that is independent of the drum drive to release manual activity.

The invention is not restricted in FIGS. 25, 26 and 27 intended example of a blocking device formed by a finger 81 which slides in this way slidable in one with a side part 8 $ of the apparatus mens frictionally connected sleeve 82 is attached that the finger between one end of the drum 84 (which the gears opposite end) and the frame passes through.

This finger is in alignment with a push button 85 Sleeve 82 and is guided in a suitable manner by a collar 85a and its button 85b in its translational movements held captive against the walls of the cover or the structure.

Kine flexible blade 86 (Fig. 25), which is frictionally engaged with the finger is connected, engages by means of a bead-shaped part 86a in a mouth hole 82a of the sleeve when the Finger is in the rearward position, i.e. in the position to block the drum. This blocking occurs

309845/0416 '*'

by placing the finger against a projection 84-a of the Drum on (as Fig. 25 shows).

If you press the pushbutton 85 », it shifts in the sleeve and releases the flexible blade 86 in its mouth hole. Continuing the thrust causes the advancement of finger 81 bent at its end, what. the Approach 84a and consequently the drum released by the Crank or the handwheel can be driven.

When unlocking, the finger is in a recess a cam 87 which is keyed on the axis of the drum and whose precisely defined profile ensures that during the rotation of the drum of the fingers runs back into the position of application against the shoulder 84-a (even if one constantly presses the push button). At the end of the return movement of the finger, the flexible blade falls again into the mouth of the Sleeve a, which automatically prevents the unlocking of the drum (passage of the finger in the sleeve), you must then press harder on the push button to advance the finger again. so release the drum.

It can be seen that in this version the user has both hands had to use, so he cannot take the discharged, i.e. the unrolled and cut paper. To prevent the fact that the piece of paper that has been dispensed falls to the ground can be seen (as in the case of distributing thin toilet paper) the partial Cut the paper in front.

It should also be noted that in this case, the process of becoming effective of the outer eccentric and the drum brake.

Only an elastic retraction for the lower part of the material roll carrier hinged to a base plate (see the first Embodiment and Figures 17 and 18) is retained.

A significant problem arises with these distributing apparatus of paper or, for example, cotton wool still on, namely to prevent the waste of material by the user forces with each pull on the protruding tape only

309845/0416

to pull out a piece, even if he is holding on to the paper pulls with a great force, i.e. even if it acts with great vigor on the drive drum.

In order to achieve this result with absolute certainty, a second variant provides for the apparatus with the in the mechanism shown in Figures 28 to 32 below. In this case, one end is the drive drum 88 a thumb 89 attached, which is axed at 90 and which can be adjusted to a limited extent by leaning against the protruding hub at one end the drum and at the other end against a stop finger 92 lays.

A three-sided bracket 93 carries freely rotatably and with the arrangement of ball bearing rings 88a the axis 88b of the drum 88, which means its thighs 93 & happens which are profiled to on the one hand tabs 93b, which carry the counterblade 94-, and on the other hand rear 93c and side stops for one To form elastomer block 95, which is axed onto the support at 96 and its rotation in the direction of arrow F (Fig. 28) against the action of a return spring 97 'is possible.

A profiled disk 98 can rotate freely on the hangers 88a and rotate against a leg 93a of the support plated and separated from the front of the drum by a space in which the thumb 89 pivots. the Disk 98 has the general shape of an eccentric, the more significant of which ! Hatchet, that is, that of the greater weight, is located downwards and has a beveled portion 98a, which to their rotary drive, following the arrow F (Fig.28), through the Thumb against an elastic return spring 99 is used, which is on the leg 93a of the support and on a protruding molded part 98b of the disc, which is intended to be placed against the elastomer block at the end of the barrel.

The support 93 is on the bottom 100a of the housing 100 in an easily demountable manner, for example by means of a structural unit attached, which has buttons 101 to remain

- 22 -

309845/0416

or removably positioned in the bottom of the housing and passing through the support while angled Plate 102 by means of its open slot 102a for the purpose of locking in a groove 101a of the buttons are inserted.

The housing 10ü is in the position of use of the apparatus by a cover 103 cover; which is hinged for example at 104 and which can be locked with a key.

The mode of operation of the apparatus is best understood with reference to FIGS. 28, 30, 31 and 32 of the drawings.

In Fig. 28 the apparatus is at rest, i.e. the paper protrudes from under the hood on the edge, ready to be pulled out by a user. At this point the Thumb 89 on finger 92, which is simply a consequence of the Weight ratios of the thumb and the position of the finger is.

The user pulls on the paper according to the arrow F (Fig. 28), which has the effect that the drum is driven in the direction of the arrow (Fig. 30) and the thumb 89. The cutting of the paper takes place as a result of the blade passing against the anvil 94. The drum continues to rotate due to its inertia and the thumb comes into contact with the elastomeric block 95 by pushing it against the side tab 93d of the support drives (arrow F, Fig. 30). This contact causes the thumb to tilt (arrow F- ⁷ , FIG. 30), which comes to rest against the hub 91.

The rounded shape of the touching end of the thumb and that Positioning the thumb and the block allow the thumb to pass along the block, which then moves during the rotation of the drum constantly on the concave profile of the thumb, keeping it constantly in contact with the hub 91, applies (Fig. 31). During this time the following one protrudes Paper tape on the marginal edge from under the protective hood.

The thumb 89 then comes with the angled part 98a of the

- 25 -309845/0416

the disc in contact and drives it the arrow F (Fig. 32) and brakes the drum (if the pulling on the paper was very strong at the beginning) until the protruding molded part 98b of the disk against the block 95 by it to tip over (arrow F ', Fig.32) against brings the side stop 93d. The inclined shape of the protruding part 98b prevents it from being passed beyond the Block, and through the elastic return force of the spring, the disc, the thumb and thus the drum return to the Rest position (Fig. 28) back, whereby the thumb is then supported against the elastomer block and from the protruding Part 98a is tipped over to rest against finger 92.

Another arrangement is provided within the scope of this embodiment to facilitate the replacement of the rolls of material. It is shown in Figures 33, 31 and 35 where it can be seen that the arm 106, which is provided with a centering bearing 107 on the blade of the roller, is hinged at 108 to the end of the mounting rod 109 in such a manner that it can be moved away from the roll by hand, some resilient return means bringing the ann back upright. Furthermore, a device is provided for locking in the removed position so that the arm does not have to be held during the role changing. For this purpose, a tab or some approach part 106a of the arm, together with part of the arm, passes through a slot 100b in the housing 10Q (FIG. 34). If the arm is also attached to the rod at 111, rotating in the other sense, it is sufficient to tilt it on one side so that the attachment part 106a is supported against the housing (FIG. 35).

In Figures 36, 37 and 38 a tilting device is shown, designed to remove the roll of paper from the drum by any length of paper without a cut to generate, i.e. to apply by free propulsion.

This device is formed by a bracket or web 112,

309845/0416

who is axed at 112 on the housing and one of them End of a roller or similar organ 114 carries that against the paper roll 115 is pressed near one of its ends.

At the other end, the bracket outside the housing is connected to a foot lever 116 by an axle 117 which is shown in FIG a curvilinear slot 10Oc of the housing is slidable.

By simply pivoting the foot lever, the roller 115 lifted by the roller 114- and you can use any length of paper peel off before cutting, which is effected after releasing the foot lever.

Finally, with Fig. 59, a practical device for the The case of the application of the paper when the drum is driven by an electric motor can be demonstrated, as is the case occasionally the first variant was described and claimed. For this purpose, an angle plate 118 is provided, which is completely or partially covers the lower frontal part of the protective hood, and which is hinged at 119 to the housing that it can be swiveled by simply pressing the hand. Pivoting causes the drum to start rotating, i.e. that Bringing out the Paiers, by the interaction of the electrical contacts 120 out. You can also find "facilities provide that limit the wastage of paper and force the user to stop acting on the panel, before a new piece of paper is ejected.
