The device, according to the invention is suitable for dispensing and cutting wiping materials of any suitable material, cellulose wadding, creped paper and the like, being intended primarily for wiping hands, semi operation - automatic or automatic, and has a joint arrangement at the level of the drum, the blade of the device to ensure the cutting of the processed material web and in particular the path of the blade to ensure the cutting of the paper.

For convenience, it will be, initially, describes the version of the device in semi-automatic operation.

The dispenser device is illustrated in Figure 1 and is referenced in its entirety as (1). It comprises six parts constituting exhaustively all the components and mechanisms required for its operation. The apparatus comprises firstly a housing (2) molded in plastic material, capable of receiving a reel (3) for feeding the wiping material, a drum (4) supporting the blade (5), and a means (6) ensuring, on the one hand, the feeding of the paper band to the drum, and secondly, the tensioning of the paper. displacement movement of the blade towards the drum, for the cutting of paper, are achieved by a means (7) to rack fixedly positioned on one of the wings (2.1) of the housing (2). A protective cover (8) protects the above mechanisms and the paper web in a reel to be dispensed. The protective cover is positioned by a snap-fastening on the housing and their junction is used to define, in the lower portion, a longitudinal slot for the passage of paper. The six aforementioned means are integrated into each other merely by snap-fastening, to the exclusion of any connecting means of screw or other type.

We will now describe each plea separately, with their own characteristics.

The housing (2) is formed integrally of plastic material, and comprises a bottom plate (2.2) having lateral wings (2.1a - 2.1b) shaped to form, in their upper part, projections triangulation (2.3) having facing and directly formed end caps (2.4), cylindrical, permitting the mounting of the material reel (3). The latter comprises, in known manner, a cylinder or sleeve (3.1) inside likely to be engaged by its ends on said free ends mount. Said wings have a slight flexibility to allow the mounting of the coil. There is further provided, ribs (2.5) of reinforcement formed between the end pieces and the base plate (2.2) of the housing, these ribs to conserve and maintain proper positioning of the turns of each coil. This base plate, in its upper part, a profiled hook (2.6) or equivalent means intended to be snapped onto the cover, to ensure closure of the assembly, the latter being completed by all locking means further if necessary.

Advantageously, the bottom plate has a cutout (2.7) which, if necessary, the access to the interior mechanisms.

The lower part (2.1c) of the casing wings extends forward over a wide depth corresponding and very substantially to the width of the device. These wings are arranged with a plurality of holes to allow, on the one hand the positioning of the associated drum to the cutting device, of centering pins, the means (7) fixed rack position, and secondly of means ( 6) for feeding the strip of material and tensioning thereof. Advantageously, said lower part of the casing wings has a cutout line (2.1d) to provide flexibility on the one hand, mounting the means (6) and particularly to allow a slight deformation to accompany the tensioning movements and pressing the paper on the drum.

The housing has, in addition, a horizontal wall capable of receiving directly formed an arch (2.8) gooseneck-shaped disposed in the middle portion of the device opposite the drum and allowing guiding of the paper web drawn. The guide hoop (2.8) formed on the housing has an end shaped yoke (2.8.1) which is engageable around the middle disk (6.3) formed on means (6) of the drum feed . This arrangement makes it possible to control the position of the feed means (6) relative to the drum so that the respective plates are perfectly opposite and support each other.

Advantageously, the horizontal wall has, on the outside, a rounded longitudinal edge (2.9) to facilitate guiding the paper as it exits, and arranged opposite a rounded longitudinal edge (8.1) similarly formed on the cover in the lower part of protective cover.

The drum (4) is formed integrally of plastic material and advantageously comprises a shaft (4.1), the ends (4.2) forming a finger, are engaged in the openings opposite the aforementioned sides of the housing. This drum comprises a small diameter shaft around which is disposed and evenly distributed a plurality of discs (4.3) adjacent and parallel identified successively from right to left looking at the drawings with (4.3.1, 4.3.2, 4.3.3, 4.3 .4, 4.3.5, 4.3.6, 4.3.7). The discs (4.3.2, 4.3.3, 4.3.4, 4.3.5, 4.3.6) have the same configuration and have on their periphery a recess (4.4) profile, can serve as the housing of the cutting blade ( 5) as will be explained later. The disc (4.3.1) is full and advantageously on its circumference a detent (4.3.1 a), and is capable of ensuring the drive control in rotation of the drum under the action of means (6) which will be described thereafter. The end disk before (4.3.1) further comprises a hole (4.3.1b) allowing the engagement and centering of one end of the axis of the blade (5). The rear end disc (4.3.7) comprises a hole (4.3.7a) near its periphery, for the positioning and centering of the other end of the blade. The rear end disc (4.3.7) is particular in that it includes an inner peripheral flange, arranged facing the disc (4.3.6) adjacent intermediate, the collar (4.5) defining a recess or inner chamber (4.5 .1) for. receiving means (7) rack. This flange also presents a cut section (4.5.2) in the same plane as the notches (4.4) for the blade slot to facilitate molding of the assembly, said cut section allowing transversely according to a given sector, access to the interior of said chamber, under the conditions described below. Said chamber allows the positioning means (7) to rack which is established in the form of a ring (7.1) fitting with play within said chamber. This ring has on the outside, two studs or projections (7.1.1 - 7.1.2) for centering, preferably of different diameter, to engage in the openings formed for this purpose on the inner flange facing the casing, in order to ensure implementation and control in off position. The other side of the crown is formed with a boss (7.2) extending semi-circular with a plurality of teeth (7.3) forming rack. Of all the component rack teeth (7), for example, the first three teeth (7.3.a) are constant profile while the following four (7.3.b) are progressive profile for subsequently cause movements the cutting blade. Particularly advantageously, the last tooth of the rack has a greater height than the other to allow escape of the cutting blade and a good penetration into the paper web. This last tooth is, moreover, as will be explained later, a way to backstop when the cutting blade have escaped all the teeth (7.3) of the rack and made to follow the periphery of the boss (7.2) for a new operating cycle, and to represent the first tooth formed on the boss (7.2). This last tooth taller another advantage which is to break the paper with the knife deeper.

The blade (5) is made in one piece of plastic and comprises a support rod (5.1), the ends forming finger (5.2), are engaged on the end of the aforementioned drum disks. The teeth (5.3) of the cutting blade portion (5) are shaped integral with the support rod. These teeth have a profile in successive triangulation, and have a conformation not smooth but curved downwardly to facilitate the attack of the strip material to be cut. Resultant, the underside has a concavity capable of forming the seat (5.4) and support area of ​​the portion of cut material and shown in the drawings. Depending on the nature of the paper to be cut, the teeth of the blade are smooth or serrated.

The blade has, at its end which is capable of being opposite the means (7) rack, a heel-shaped part (9) profiled. The latter has a rear part (9-.1) by triangulation with a jointing angle of rounded (9.2) and two curvilinear edges (9.3 - 9.4) opening towards the widest portion of said heel which is shaped with a plurality of teeth (9.5) forming a rack, said teeth being arranged in progressive distancing with respect to the axis of the blade, the drive tooth (9.5.1) being of greater height to ensure the engagement. This heel-shaped part is secured to the axis of the blade, but in an eccentric position, so as to cause the angular pivoting of the blade and the workpiece itself in a limited position. This pivoting allows the accommodation of the teeth of the saw blade inside of the cavities formed on the intermediate discs of the drum, in a maximum withdrawal position, said blade being in a lower plane to the generatrix defined by the discs of the drum. The outer overflow of the toothing of the blade is limited by the abutment of the teeth with respect to said notches. As will be described later, the rack formed on the heel associated with the blade is arranged to cooperate with the fixed rack formed on the means (7) for causing, under given conditions, the displacement and the output of the cutting blade. Thus, the special provisions of teeth formed on the workpiece (7) and heel (9) progressive toothing, one obtains a movement of the cutting blade to a gradual speed. The first meshing teeth correspond to the phase of the most significant effort when the blade teeth penetrate the paper. After the paper has been penetrated, cutting starts slicing and effort becomes less important. It accelerates the rate of cutting by pulling on the paper, and there is obtained a larger gear by the fact that the teeth are larger, allowing faster cutting.

There is illustrated, in an advantageous alternative embodiment, Figure

12, a side view more particularly illustrating the end disc (4.3.7) formed on the drum with a second complementary anti-return abutment means (4.3.7c). Said means is formed, when carrying the disc concerned, and is in the form of a flexible tongue, free at one end, the tab cam and a member by elastic relaxation light externally projecting with respect to the periphery of the disc . This tongue is located opposite the axis of rotation of the blade and designed to come into stop on the abutment (10) formed on the horizontal wall of the housing. The advantage of such additional anti-return stop which lies in the case where by appropriate manipulation of the manipulator, is tear the paper before cutting. This could happen in the case of a violent oblique tension but not corresponding to the normal use of the device. When the cutting blade has passed, after rotation of the drum, the pressing means (6), the non-return flap (4.3.7c) in front of the stop (10), and in case of back of the drum rotation, tongue comes into contact with the said stop, stopping the rotation of the drum.

We will now describe the means (6) which ensures feeding of the paper band to the drum and the paper tensioning.

This means (6) comprises a shaft (6.1) having at each of its ends of the centering fingers (6.2) to snap between the side wings of the apparatus housing. On this shaft there is arranged a plurality of disks or washers (6.3), the assembly being integral plastic. The number of disks or washers is equal to twice the number of intermediate discs formed on the drum. Thus, after positioning and the snap-fastening means (6), a number of discs (6.3a) will rest on the intermediate discs (4.3.2 - 4.3.3 - 4.3.4 - 4.3.5 - 4.3.6) formed on the drum, while the other intermediate discs (6.3. b) will be located in an intermediate plane between two discs (6.3.1) formed on the drum. The set will help ensure tensioning of the paper. Alternatively, the shaft (6.1) may be solid or otherwise lightened.

The means (6) has, at one end which is opposite to the rack device, a disk (6.4) of larger size, forming handwheel. This disc (6.4) is positionable between the end disc of the drum and the flange facing of the casing. This disc flywheel assembly advantageously has on its periphery a serration (6.4.1). In addition, the wheel (6.4) has adjacent its inner face, a notched cylindrical shoulder (6.4.2) complementary to diameter identical to those formed along the shaft (6.1) to abut on the first disc formed on the drum in order to ensure, after manual intervention on the hand wheel, the rotation of the drum. The handwheel, after snap-fastening and protective cover assembly (8) substantially beyond the latter to be pushed manually by the operator.

Before describing the operation of the apparatus should be of describing particular complementary means which have an effect on the positioning of the cutting blade during rotation of the drum, thereby defining, for the latter, a path very special. These two means are arranged on the side of rack devices controlling the output of the cutting blade. In its lower part, the wall housing (2) has, on its horizontal wall near the lateral side, opposite the rack means, a shaped limit stop (10) with curved profile forming a ramp, against which will come in the heel support (9) profile associated with the blade (5) and support teeth (9.3) of the rack. This stop (10) occurs to cause, after the cutting operation and disengagement of the racks therebetween, the reintegration of the cutting blade in the notches formed on the intermediate discs of the drum.

By profile-shaped ramp, said stopper causes the tilting of the blade according to the arrow (F2) in a direction opposite to the 0 direction of rotation of the drum causing its storage in the aforementioned notches.

In addition, there is provided a supplementary means of the cutting blade position control in the notches formed on the drum 5 ι or alternatively ensuring a locking in position of the cutting blade before the start of a new operating cycle .

To this end and in a first embodiment, is provided on the means (6) ensuring the control in rotation of the drum and the pressure on the paper, a disc (11) further, at the end 2 Q Judit means (6) and arranged in the plane of movement of the heel-shaped part (9) of the blade. This disc (11) further has a function to act as abutment and guide, if for any reason, the blade is in an extended position relative to its housing notches on the drum. Rotation of the drum will cause the abutment of the heel-shaped part (9) by one of its curvilinear portions, against the disc (11) supra. The additional rotation of the drum will result, thereby pivoting and tilting downwards (arrow F3) of the heel-shaped part by causing the retracted again from the blade into the notches formed on the drum, thus preventing the teeth of the blade can come into contact with the means (6). This particular arrangement provides additional security.

Alternatively, the projection (7.2) formed on means (7) rack has an outer offset (7.4) that constitutes a stop means 0 and locking in position of the heel (9) asocié to the blade causing during the return the blade locking thereof in the aforementioned recesses of the drum.

The protective cover (8) has, in the lower part of its wings, openings for its snap-fastening on the wings of the support housing by means of the fingers or projections (12) of centering and positioning. Said housing is also shaped in its bottom part with a wall (8.2) capable of coming opposite the horizontal bottom wall of the housing, but leaving a gap or slot to allow the output device paper . The front protective cover has a vertical slot (8.3)

20 for the passage of the hand wheel means (6).

In addition, and in a particular arrangement, the bottom portion of the protective cover has a plurality of parallel projections (8.4) integrally shaped and obtained during the molding of cover 2 §es projections being intended to come opposite the intermediate discs of drum, significantly penetrating into the recesses (5.5) of the blade, during rotation of the drum, and thus in the bottom portions of the teeth of the cutting blade. These projections essentially aim to ensure better guidance of shot material. To avoid interference with the operation of the apparatus, the recesses (5.5) have been formed on the blade support rod to allow proper operation of the assembly. It is therefore necessary to describe the operation of the semi-automatic machine, with particular reference to Figures 4 to 7 of the drawings.

The apparatus being loaded with a coil material mounted on the end pieces, on the lateral sides of the housing, is undertaken before the loading of the device. After the initial opening of failover protection cover, the operator has the free end of the coil of material between the means (6) and the drum (4) and manipulates a few degrees, the handwheel so to cause the driving of the web of material between the drum and the means (6) and its output to the rear of the unit, without, however, lead in and out of the latter by the proper slot. The strip of material is held in tension by the plurality of discs formed on the drum and the means (6). The one-piece hoop gooseneck formed on the housing, ensures, in addition, if necessary, the paper guide. This a prior loading space being performed, the device cover is closed, and the device is ready for use. At this point the blade is housed completely in the notches formed on the drum. There is no meshing of the rack formed on the blade with the fixed position rack formed on the means (7), accommodated in the chamber of the last disc of the drum.

The process step of cutting is as follows. The end of the paper web is still located inside the device in an area corresponding to the rear of the drum towards the gooseneck portion. The operator manually turning the handwheel in the direction along arrow (F), which causes, by rotation of the means (6), the rotary drive in a direction opposite the drum, in the direction of within the housing. Beginning of the cycle, the blade is disposed within the notches, leaving a gap of several millimeters with respect to the dummy generator formed by the intermediate discs of the drum before opening. The beginning of the rotation of the drum will cause, under the action of means (7 and 9), a displacement of the blade of a few millimeters so that when the first tooth of each means (7 and 9) has meshed , these teeth are in the plane defined by the axis of the blade and the axis of the drum. In this situation, the cutting blade is located at the beginning of contact with the paper to be cut (Figure 11).

Gradual rotation will allow the presentation of the respective first teeth formed on the rack associated to the blade and the fixed rack of the means (7). The end of the material web comes out of the slot formed on the device, and can be gripped by the user. The latter then performs a traction causing rotation of the drum, and thereby ensuring the continuity of the cutting operation. The blade, by eήgrènement teeth of the two racks, will be pivoted out and severing the paper web, due to the meshing of the teeth progressive profile. The output of the teeth takes place at the rear of the device and the material web will be torn and gradually, the pivot blade in the notch formed between the intermediate discs of the drum. The total output of the blade will correspond to the exhaust and meshing of the last two teeth of the racks between them, the last tooth formed on the fixed rack causing the maximum output of the blade.

After exhaust toothings therebetween racks for an instant during rotation of the drum, the blade remains in the "extended" position, the heel-shaped part no longer being in contact with the support disc of the rack in fixed position.

Retraction of the blade then takes place by the abutment and contact with the heel-shaped part of the blade with the curved stopper fixed on the bottom wall of the housing. This curvilinear ramp portion causes a reverse effect tilting and retraction of the blade into the notches formed on the discs of the drum. Pivoting the blade resulting ipso facto that the heel-shaped part, the latter is swung without contact with the disk fixed position of the means (7). When the heel-shaped part comes into the exhaust position of the curved abutment, the teeth of said heel-shaped part present themselves while facing the teeth of the input area formed on the fixed disk, for a new cycle operative until the early engagement of the first teeth of the racks.

If, for any reason, the blade had to disengage notches formed on the intermediate disc, resulting in an overflow of the heel-shaped part associated with the blade, the continuous rotation of the drum then drives the contacting said part forming heel with the stop disc formed at the end of the means (6), which in turn causes the removal and reinsertion of the blade in its housing defined by the indentations on the intermediate discs.

Alternatively, maintaining and blocking in position of the blade in the notches in the second phase of the operating cycle return the drum corresponding to the intervention of the curved stop (10), are obtained by locking said blade in supplementary the shoulder aid formed on the boss (7.2) which causes the retention of the blade in the notches of the drum. Unlocking takes place when the heel (9) associated with the blade gets a new presentation position of its teeth with those formed on the medium (7).

So there is a total security in the functioning of the whole. The semi-automatic device described comprises a limited number of parts, six as indicated above, but each having multiple functions as was evident in the description.

There is shown in Figure 7, schematically, the trajectory (T) of the cutting blade.

We will exhibit the following various complementary facilities of the unit. According to a first arrangement, illustrated in Figures 13 and 14 of the drawings, the housing (2) is arranged with a cover (8) articulated with the inner face (8.1) is arranged with a protrusion (8.2) projecting established in a perpendicular plane, said projection being disposed horizontally at a level such that it comes opposite to the meshing zone of the paper between the means (6) and the drum (4). This projection is intended to guide and to introduce the first web material to be dispensed during loading, to facilitate its introduction between the presser means (6) and the drum (4). Said projection so formed is flush in the space, the introduction of the paper between the means (6) and the drum (4). This arrangement is particularly convenient and produces no additional manufacturing cost, when making the cover.

According to another important feature of the invention, the prior output of the wiping material web must be possible, in an easy way on a few centimeters, that in the case where the user can not manipulate the hand the handwheel. In this case, in a first implementation, the handwheel (6.4) of the aforementioned type overflowing outside the cover, has a cross shape (6.5) or any other polygonal cross section with alternating cavities (6.6) with forms projections. These cavities are such that they allow the positioning of the forearm of the user who may then, by a lowering movement, cause rotation of the steering wheel and therefore of the associated drum, ensuring the output of the band material with a view to its subsequent entry by the hands by the user.

According to another arrangement, in this implementation, there is provided forming, on one of the discs of the drum, a slight boss (34) in cooperation with said disc facing the means (6), ensure a provisional voltage area of ​​the paper web by pressing with the means (6) to facilitate tearing of the paper web drawn. As an alternative to this provision, it is expected that the engagement of the drum with the means (6) is effected by two toothed discs formed respectively at the ends of drum (4) and means (6), as shown FIG 19. the two discs are arranged at one end of the body of the apparatus, as was described in the original patent application. To facilitate separation of the paper web, one (35) of the teeth is longer than the other to ensure against backup-zone.

In both situations of use of a projection or a tooth, to facilitate the separation of the paper web, and their position is determined by particular relative to the cam cooperating with the rod and the actuating means. This position is such that the cam or the longest tooth is situated, to be facing the means (6) tensioning of the paper web, before any action on the operating means, and when the spout of cam is in contact with the heel of the rod. The paper is in this position just at the exit of the device, as shown in the drawings, and does not overflow. The operation on the operating means will therefore enable the output of the paper and cause a paper web tensioning by the restraining effect provided by the boss or the particular tooth, by causing it to tear.

In this implementation, the cam assures, by the fact of complete rotation of the drum, the tilt operating means.

According to another important feature of the invention, using a device referred to in its entirety as (40) for allowing the pre-release of the paper web from the apparatus, for its gripping and traction by the user. This device profile, angled in two parts, integrally formed with a portion forming a lever (41) externally projecting from the device, to be manipulated by the operator, and being extended by an arm (42) inside of the apparatus, to ensure partial rotation of the drum, according to a given sector to allow the output to a few centimeters from the paper web. Said arm (42) is located in a plane parallell to said lever and is arranged at its end with a toothed sector shape (42.1) capable of cooperating with a rack (44) disposed on the axis of drum (4) receptor the cutting tool. In this integral assembly between the lever part and the arm part is provided, in the bent connection region (43), a gap (45) allowing the passage of the corresponding side wall of the housing (8), the latter having at the back, a passage opening (46) of the bent part of the device. Said lever (41) has, in its rear part, a bend forming perpendicular extension (43.1), substantially horizontal, with itself a vertical extension (43.2) defining, by a suitable shape, the articulation zone (43.3) of device. Specifically, the hinge area is provided with two centering studs (43.4) opposite likely to engage in openings formed on the one hand in the lower part of the side wall of the corresponding housing, and on the other hand, reported on a flange (47) disposed opposite to constitute a shaped clevis allowing the articulation of said device. The arm part is made from this articulation zone and extends forwards in the same plane as the lever. It has a front end shaped in the thickness of which is formed integrally on the one hand, an L-shaped angular sector, notched (42.1) and on the other hand, a ribbing (42.2) particularly forming a ramp for cooperating with a cam (48) profiled disposed on the axis of drum (4), the serrated portion (42.1) cooperating with the rack (44) disposed on the drum axis.

The end of this arm and a toothed angular sector with a plurality of teeth (42.3) of equal toothing and with an end tooth (42.4) located in the same plane as the ramp part above. In the thickness of said adjacent end arm toothed sector there is provided a rib (42.2) of great length disposed in a plane inclined relative to the toothed sector supra. This ribbing defines on its front part, shaped ramp capable of cooperating, as will be described later, with a shaped cam arranged on the drum axis. The angular position of rib, relative to the teeth, is established judiciously to allow, after the release over a few centimeters of the paper web, the tilt lever. In its thickness, the arm portion has a relief opening (42.5). The drum has, starting from its axis of rotation, by overflow, the cam (48) above, and a rack (44) comprising a plurality of teeth. Said cam has a particular profile with a shape "S" flattened. Thereof is defined with a first half portion (48.1) semicircular against which is positioned above the rack and a second portion (48.2) disposed opposite semi-elliptical. The junction of the two half circular and elliptical portions with respect to one another is established with a rectilinear profile (48.3) on one side and a curved profile (48.4) forming a ramp on the other side. The shape of this cam defines a particular path that cooperates with the rib (42.2) supra, under the conditions of operation following, with reference to Figures 21 to 26.

The wiping roller apparatus being loaded, the device is in rest position, that is to say that the lever (41) is in a horizontal position to be manipulated by an operator. The wiping paper is not released. The rack (44) mounted on the axis of the drum meshed with the first teeth of the toothed sector of the arm (42), while the profiled cam (48) "S" is in a plane oriented downwards, forms "S" being substantially vertical. The ramp portion (42.2) of the arm in projecting end, forming lug (42.6) is raised upwardly maximum distance position with respect to the cam profile. Actuation downwards according to arrow (F1) on the lever, as illustrated in FIG 22, will cause a toothed sector co-effect of the arms and rack mounted on the drum axis, the rotation part of it, allowing the output to a few centimeters of paper tape. In this phase, the profiled cam "S" fixedly mounted on the drum has taken a new orientation corresponding to the partial rotation of the drum and lies in a plane such that the rib part of the spout forming arm rests on the part curvilinear (48.4) of the ramp. The teeth of the rack and the sector gear formed on the arms are no longer engaged.

According to Figure 23, there is shown the tension of the outgoing material web by the user. This tension will result in additional rotation of the drum, and thus the overflow of the paper web. During this movement, the fixed cam (48) mounted on the drum shaft will rotate according to the arrow (F2) and cause, because of its curved profile, constantly pressing the spout (42.6), lifting of the device consisting of the arm (42) and the lever (41). In this situation, the rack (44) and the toothed sector arm are distant from one another, thus allowing, for a clearance, the easy lifting of the arm-lever.

According to Figure 24, there is shown the position of the device comprising the arm and the lever in the respective position with respect to the shaped cam and rack arranged on the drum axis. This representation corresponds to the time of cutting the paper web by the cutting device inserted and positioned in the drum, as previously described. In this phase of operation, the lever portion (41) is raised to maximum, and the arm part (42) engages a stop (49) fixed to the side wall of the housing to limit the movement. The cam (48) profiled in "S" then has a substantially horizontal position, and the straight portion is also horizontal. The first teeth of the rack and the arm of the sector gear are opposite one another ready to engage. At the end of traction and after cutting the paper web, the lever returns to its initial position as shown in Figure 2, the rack and the sector gear being engaged. During the passage in this position, there is obtained a start of engagement of the teeth of the rack with the toothed sector of the arm.

The implementation of this device is particularly advantageous in that it simplifies the assembly of the whole. In addition, the operation of the device including the lever is easy to implement.

Another improvement on the apparatus resides in an embodiment substantially altered by the means (6) for feeding the strip of material towards the drum (4), and which is illustrated in particular in Figures 27 and 32, to improve the distribution of the material web, irrespective of the direction of pull to the end of the strip by the user. To do this, the means (6) comprising a shaft (6.1) and a plurality of discs (6.3) to be connected with the discs (4.3) formed on the drum is established to provide some flexibility for deformation relative to said drum, and secondly by providing a setting successive folds of the web of material when in contact between the means (6) and the drum (4) during distribution.

According to a first feature, there is provided on either side of discs (6.3) to have complementary discs (6.5) have a diameter (D1) substantially greater than the diameter (D2) of the discs (6.3). Thus, when the discs (6.3) are in contact and engaged with the discs (4.3) formed on the drum, additional disks (6.5) have a slight tendency to penetrate the material in the formed gaps between the successive discs of creating drum a hair setting (Figure 27) or successive corrugations resulting in improved paper tensioning transversely to facilitate cutting. Additional discs (6.5) have a smaller width than the discs (6.3).

According to another feature, the discs (6.3) of means (6) for feeding the paper web of material are constructed with a decreasing diameter from the middle central disc, according to a same angle α on either side. This reduction in diameter of the various discs (6.3) is achieved by a gradual decrease of a few tenths of millimeters in the diameter of consecutive discs. The means (6) which is locked between the lateral sides of the housing can thus be placed substantially bending the assembly, although the ratio discs each other with the drum are in contact. In addition, the drum (4) can he -even, on its shaft between certain discs (4.3) to be furnished with notches or zones of weakness (4.6), preferably obtained by a reduction in diameter to allow it to provide flexibility in combination with that obtained by the means (6) above. Is thus obtained thanks to these particular arrangements a flexible mounting means (6) on the drum (4) and better tensioning of the paper for its cutting.

Moreover, some of the peripheral surfaces of discs (4.3) can be equipped with gripping areas (4.7).

According to another feature, to facilitate the distribution of the material, especially its output below the protective cover, is provided on the drum, to add additional disks (4.8) between the existing drives by forming projections zones (4.9) relative to the tangential generating discs (4.3) above. These zones forming projections (4.9) are established in particular by being adjacent to the notches (4.4) receiving the cutting blade holder formed on the disc. These forms projections are alternately arranged between the disks (4.3) engaging the discs (6.3) of means (6), they thus pass in occurring intervals between the complementary disc (6.5) formed on means (6) during the rotation of the drum. These projections are intended to facilitate the output of the paper at the lower end of the cover.

According to another feature for reducing the noise of operation of the apparatus, it may be disposed on some of the discs of the drum and / or the pressing means (6) of elastomer or equivalent dampers rods for smooth operation of the apparatus.

The advantages are clear from the invention. It emphasizes the new concept of the device, its rapid installation and perfect adaptability to a semi-automatic operation.
