• the coil can bear directly on the drum.
• the outlet of the cutting blade (4a) near the support of the pressure roller and the drum (approximately two to four centimeters) promotes the formation of folds in the strip of material by a lack of tension between the abovementioned support and the penetration of the blade into the material, so that the cut is not always clean and straight.
• This drawback is currently found in the two cases where the dispensing device comprises a reel of material in direct contact with the drum, or when the dispensing device comprises a roll of material suspended without contact with the drum, but this contact being ensured by the pressure roller bearing on the receiving drum of the cutting device.

• the strip of material which comes into contact with the drum to be sectioned by the cutting device is perfectly maintained due to the function played by the lower strand (20b) of the third belt (20).
• the support (23) of the fourth pulley (22) has a curvilinear edge (23a) facing the drum to be concentric with the periphery of the drum, and thus accompany the strip of material towards the outlet of the device.

• the pressure roller is arranged at one end with a span (8b) of smaller diameter capable of authorizing the engagement of a telescopic axis (24) whose end (24a) engages in the notch of the rocking lever (9).
• the spacing of the flanges (lb) allows the disengagement of the pressure roller relative to the telescopic axis.

• the pressure roller in contact with the spool is subjected to a normal rotation when the strip of material is pulled by the operator.
• the tension mechanism inside the pressure roller is stressed in two cases: • at the time of cutting when the cutting blade comes out of the drum because there is a stretching of the strip of material in tension between the two points of coil-pressure roller contacts on the one hand, drum-blade output on the other. There is thus by the blade outlet an enlargement of the diameter of the drum when the blade deviates.
• the pressing roller return means corrects and somehow compensates for this effort by allowing a particular complementary rotation of the pressing roller against the return means, this rotation compensating for the tension on the material. There is therefore a voltage regulation effect.
• said mechanism is arranged to have a multiplier effect.
• This specific implementation is then illustrated in FIGS. 6 and 7. More specifically, the said pressure roller is arranged at one end (28a) with a shoulder shoulder of great length capable of receiving a ring (29) forming a sleeve whose end ( 29a) is capable of engaging in a hook shape of the tilting lever (9) of the pressure roller.
• the other end of the pressure roller has a shoulder of great long shoulder (28b) capable of receiving the tension reduction mechanism. More particularly, the very long span receives a first ring (30) or end piece indented internally and forming a housing for the reception of a return spring (31).
• This ring has a projecting surface (30a) on one of its lateral faces, facing the support zone of the material on the pressure roller.
• This projecting surface is capable of following the peripheral contour of a flange (28c) formed on the fixed part of the surface of the pressure roller.
• a point of projection or fixed stop (28d) is disposed on said flange also allowing the anchoring of one end of the return spring (31).
• a sheath (32) Adjacent to the positioning of said first ring, a sheath (32) is provided with a flange (32a) passing through the first ring and against which also comes to bear a second ring (33) capable of being rotated against 'a second elastic return means (34).
• This second ring or end piece is disposed at the end of a support sleeve
• This second ring has a stop projection (33a) and is set in motion during the rotation of the drum against its elastic return means, one end of which is fixed in the bottom of the ring and the other end to a fixed point of projection (32b), formed on the collar (32a) of the sleeve (32).
• This secondary projection point (32b) is advantageously in angular offset with respect to the fixed projection point (28d) of the first flange.
• the angular differential is advantageously a few degrees between 5 ° and 10 ° for example. It can be different depending on the amplitude that you want to give to the tensioning mechanism.
• Said secondary projection is mounted integral with the support of the first ring to then allow the latter to be driven under the conditions set out below.
• This reduction mechanism can include two rings in the above example, but if necessary, depending on the nature of the material distributed, the pressure roller can be arranged with one or more complementary rings.
• the device comprises, for its front part, a fixed front flap (27) which is snapped onto the lower part of the flanges (lb) of the casing, in suitable openings (lb6).
• a protective plate (28) is also positioned between the front part of the flanges (lb) of the device through an appropriate opening (lb7). This protective plate extends at the rear of the device to separate the receiving area of the drum and the second pulley from the receiving area of the material reel and the pressure roller.
• This plate (28) thus has projections (28a) on its rear edge
• the plate also has on its longitudinal edge (28c) before projecting fingers (28d) which penetrate into openings (lb8) formed between the flanges.

• the drum is fitted in any known manner with a retractable serrated cutting device, as described in the applicant's prior patents, and in particular in patent FR 2332215.
• the dispensing device thus described according to the invention has many advantages.
• Another advantage lies in the better guiding and holding of the strip of material on the drum towards the cutting zone.
• the strip of material is in fact held by the lower strand (20b) of the third belt over a large angular distance during the rotation of the drum before the output of the cutting blade. There is therefore no possibility of shifting of the strip of material.
• the deflection roller can be arranged at an adjustable distance from the drum in order to take account of the particular characteristics of this drum. It can indeed be a drum with variable diameter depending on its ability to act as a format selector.
• the drum can be simple, that is to say without a selective format function but with a different diameter.
• the material dispensing device offers very flexible and noise-free operation. Its construction is simple. It also allows cutting of any kind of wiping material.
• the dispensing device can also be used in its application of toilet paper dispensing.
• the various mechanisms are oriented in a position perpendicular to the bottom face of the casing.
• Two flanges identical to those (lb) described are arranged parallel to the bottom face of the casing. It is simply added a complementary fixing wall for positioning the support (23) of the fourth receiving pulley of the third transmission belt.
• the shape of the drum can be arbitrary since there is no longer any support and contact with the loading reel or with the pressure roller on the drum.
• the establishment of the cover tends by its contact with the protruding plates of the flanges to ensure perfect maintenance of the mechanisms and components of the device. Removing or opening the cover allows the operator to grasp the protruding dishes, causing the elastic spacing of the flanges
