A device for inserting a strip of material in a dispensing machine for material wipes of the type in which the machine includes a housing, a cover, the housing having end shields that support a reel holder, and a drum with a cutting device. The drum includes a cam associated with a start and return spring, a protection flap being located in front of the drum along with a pressure roller resting against the drum. The protection flap has an upper extension forming a support frame devised to accommodate a hinged secondary flap and a swivelling shaped plate is located behind the drum and capable of supporting a service roll that is being used up. The swivelling shaped plate cooperates with a mechanism capable of locking the secondary flap in position when a spare roll (RR) is being loaded and the service roll (RS) is positioned so that it can be used up.

The invention relates to the technical field of dispensing machines for tissue-paper or similar type wipe materials intended for wiping the hands or toilet paper, the strip of material being folded or not folded.
The Applicant has developed numerous automatic and semi-automatic versions of dispensing machines of this type.
The dispensing machines are of the type comprising a housing (1) capable of accommodating a swivel cover (3). The housing accommodates end shields (2) that support a reel holder (4) of wipe material in its upper part. In the lower part, a drum (5) is rotatably mounted with said end shields and is devised to accommodate the cutting device (6). The drum may be designed so that one of its ends has a cam (7) associated with a start and return. spring (8) one end (8a) of which is attached to a finger (7a) associated with the cam and the other end (8b) of which is associated with a fixed part of one of the lateral end shields (2) of the housing. Generally speaking, in the lower part of the machine and towards the front facing the drum, there is a hinged protection flap (9) suitable to prevent entry of the user's hands and any unwanted contact with the cutting device. A pressure roller (10) is located between the end shields of the housing and rests against the drum. The strip of material paid out from the reel is inserted between said drum and said pressure roller.
In order that the object of the illustrated invention may be more readily understood, non-exhaustive reference is made to the accompanying drawings in which:
FIG. 1 is a profile view of the dispensing machine according to the invention when it is dispensing a reel of material normally;
FIG. 2 is a similar view to FIG. 1 showing the presentation of the end of a strip of material from a spare roll when the service roll is in the process of being finished up;
In order that the object of the invention may be more readily understood, it is described below in a non-exhaustive manner, reference being made to the accompanying drawings.
The dispensing machine comprises the components described above.
Protection flap (9) has lateral protruding pins (9a) that engage in and swivel in openings (2b) on the end shields (2a) of the housing. A return spring (8) elastically links said flap via a fixing lug (9b) to a protruding finger (7a) formed on cam (7).
