• This device is likely to be implemented when the use roller (R1) is at the end of service, that is to say that, compared to its initial diameter, only a few sections of paper strips remain. to distribute. Under these conditions, the roll at the end of service must be moved by an operator and be positioned in the bottom part and at the rear of the device. forming receptacle (14), as shown for example in Figure 6 of the drawings. Another so-called reserve roller (R2) is put in place.

• tongues (20) projecting internally, with elastic deformation capacity, to come to bear on said roller (R1) and thus ensure, in combination with the aforementioned discs (19a) , means for retaining the roller generating a force in opposition to that exerted during the pulling of the paper, thereby allowing detachment of the paper from its support.
• the second mechanism is thus implemented as follows.
• the tester (18) is arranged from an articulated support piece (21), forming a lever, arranged parallel along the flange of the device.
• This lever has, near its front end, an oblong slot (21a) forming a passage and guide slot relative to a means (22) integral with the flange (4) in a fixed position.
• This lever can be moved backwards under the effect of a means of thrust (23) which is, in practice, produced by the oblique lower profile of the cover (3).

• Said axis (27) is arranged axially and vertically in a support piece (28) formed at the end of the tester member (18).
• This support piece (28) pivots by axes (29 - 30) from profiled lugs (31 - 32) parallel formed on the flange (4) and this against a second return means (33) of the spring type one end (33a) of which is fixed at the rear to a fixed point (33b) on the flange (4) of the casing.
• the tester member (18) is capable, during movements of the lever (21), to pivot and pass through a profiled cutout (4a) formed in the flange (4) facing to come close to the plate ( 17) transverse located at the rear of the drum and in certain operating phases by crossing it to overflow internally towards the drum, as will be explained later.
• the aforementioned support piece (28) has an oblong profile and the axes, or the same through axis, associated on the one hand with the lever, and on the other hand with the second return means, are offset towards one end.
• the action of the lever causes the pivoting of the support piece (28) in an arc of an arc effect causing the radial pivoting of the tester member over more than 90 °.

• the rotation of the drum by a known operating button (38), disposed at the other end of the axis of the drum, allows, without difficulty, the rotation of the drum driving the strip of paper on a section corresponding to the circumference of the drum on a lathe before it is cut by the cutting device, according to well-known methods.
• the device remains in this arrangement constantly until a new intervention occurs. The latter takes place when the maintenance service or the operator realizes that the service roller (R1) under load is in the end of unwinding situation. It is therefore necessary to position another reserve roller (R2).
• the operator opens the cover, which releases the lever (21) and the slide and returns, in the initial retracted position, the tester.
• the operator removes the initial service roller (R1) during depletion and places it at the bottom of the device in the bottom receptacle.
