7- Dispensing machine as claimed in either of claims 5 or 6 characterised in that support (23) of fourth pulley (22) has a curved edge facing the drum and concentric with the periphery of said drum, thus accompanying the strip of material towards the outlet of the machine.

8- Dispensing machine as claimed in any of claims 5, 6 and 7 characterised in that the ends of the idler roller are fixed to end shields (1b) in openings, the clearance of said idler roller with respect to the drum being adjustable depending on its position in above-mentioned openings.

9- Dispensing machine as claimed in any of claims 1 to 8 characterised in that one end of pressure roller (8) is designed to cooperate with a mechanism for tensioning the strip of material, said mechanism being mounted on swivelling lever (10).

10- Dispensing machine as claimed in claim 9 characterised in that one end of pressure roller (8) is designed with a cylindrical cavity (8c) allowing partial engagement of an end piece (25) which rests on swivelling lever (10), said pressure roller accommodating pulley (15) used to guide the second transmission belt, said pressure roller being designed with a collar (25b) comprising a limit stop (25c), said pressure roller extending into cylindrical cavity (8c) as a cylindrical bearing surface (8d) on which there is an elastic return means (26), said elastic means being attached firstly to collar (25b) and secondly in the bottom of the cavity.

11- Dispensing machine as claimed in claim 10 characterised in that the transverse face (8d) of the pressure roller has a protruding shape (8e) acting as a limit stop and cooperating, when the pressure roller rotates, with the limit stop (25c) of end piece (25) in order to limit the tensioning of the pressure roller in opposition to elastic return means (26).

12- Dispensing machine as claimed in claim 9 characterised in that it comprises a tensioning mechanism with a gearing-down effect.

13- Machine as claimed in claim 12 characterised in that the pressure roller has a shouldered bearing surface (28b) on one side accommodating at least two rings (30-33) or end pieces that are successively actuated in opposition to elastic return means (31-34) when the strip of material if pulled, one of the rings (33) causing rotation of the other ring (30) after rotational travel and providing a gearing-down effect and tensioning the material to be cut, the pressure roller fulfilling the function of tensioning the material to be cut.

14- Machine as claimed in claim 13 characterised in that long shouldered bearing surface (28b) accommodates the tensioning gearing-down mechanism, the long bearing surface accommodating a first internally cut out ring (30) or end piece forming a receptacle to accommodate a return spring (31), said ring having a protruding bearing surface (30a) on one of its lateral faces opposite the area where the material rests against the pressure roller (8), capable of following the peripheral contour of a collar (28c) on the fixed part of the bearing surface of the pressure roller, a protruding point or fixed limit stop (28d) being located on said collar also making it possible to attach one end of return spring (31),

• and in that the other end of said return spring (31) of the first ring (30) is connected to the above-mentioned long fixed bearing surface.

15- Machine as claimed in claim 14 characterised in that, adjacent to the position of said first ring (30), there is a bush (32) with a collar (32a) which passes through the first ring (30) and against which a second ring (33) comes into contact, this ring being capable of being rotated in opposition to a second elastic return means (34), this second ring or end piece being located at the end of a support sleeve (35) which in turn has, in opposition, a pulley (35a) which accommodates transmission belt (C2) associated with the drum of the dispensing machine,

• and in that this second ring has a protruding limit stop (33a) and is moved when the drum rotates in opposition to its elastic return means, one end of which is attached to the bottom of the ring and the other end of which is attached to a fixed protruding point (32b) on the collar (32a) of bush (32), said second ring causing rotation of said first ring.

16- Machine as claimed in either of claims 14 or 15 characterised in that the secondary protruding point (32b) is ideally angularly offset relative to fixed protruding point (28d) of the first collar.

17- Machine as claimed in claim 16 characterised in that said secondary protruding point is physically joined to the support of the first ring to then allow this ring to be driven.

18- Dispensing machine as claimed in any of claims 1 to 9 characterised in that the second end of the pressure roller has a bearing surface (8b) allowing it to fit in a telescopic shaft (24), one end of which fits on swivelling lever (9).

19- Dispensing machine as claimed in any of claims 1 to 9 characterised in that it comprises, in its front part, a fixed front flap separately mounted on the lower part of the end shields of the housing in openings (1b6).
