DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to small electrical household appliances, capable of facilitating some operations usually performed manually or by manually operated devices.
BACKGROUND ART
The use of electrical household appliances sometimes has positive effects in particular fields, such as hygiene, very important specially in public areas, places of work, communities and the like, particularly when food and hygienic services are concerned.
In such places there are usually used reels of paper, from which one takes pieces of paper of different length, according to the needs.
At present, these reels of paper are inserted in very simple devices; the user manually unwinds and tears a piece of paper he needs, using the pre-cut lines made in the reel of paper, or suitable blade with which the device is equipped.
The most common types of the above mentioned devices cannot avoid the contact between the user and the paper remaining on the reel, i.e. the paper that will be used by the next user.
This unacceptable situation causes the users' precautionary behaviour, what means that they take first a piece of paper to throw away and another piece of paper to be used.
This results in great waste of material and consequently, in high operating costs, due to frequent interventions of supplying staff.
DISCLOSURE OF THE INVENTION
The object of the present invention is to propose a dispenser of pieces of paper, constructed in such a way as to supply pieces of paper, pulled out from the reel of paper contained therein, of desired length or of length equal to one or more predetermined value, i.e. distance between two following transversal pre-cut lines made in the same reel of paper, the whole without any contact between the user and the not taken paper.
The object as defined before, is achieved by means of a device for supplying pieces of paper from a paper strip with or without transversal pre-cut lines, including a box-shaped housing with a recess for receiving a reel of paper, a first pulling-out mechanism with upper and lower rollers connected to each other by belts which run into grooves made in the rollers, the grooves of the upper roller having innermost diameter bigger than the diameter of the lower rollers' grooves, a second pulling mechanism including a second pair of upper and lower rollers also connected to each other by belts which run into grooves, with the grooves of the upper roller having a diameter bigger than the diameter of the grooves of the lower roller and with a run of each one of these last mentioned belts facing a corresponding run of a previously mentioned belt of the first pulling-out mechanism, a cover hinged to the housing for insertion of a reel into the recess and adapted to assume one or the other of several positions, and power driving means activated by control means and provided for operating said pulling-out mechanisms.
According to a first embodiment, the cover can take two positions which correspond to a first situation in which the upper rollers are almost in contact which each other, whereas the lower rollers are separated from each other to define a condition in which a piece of paper is unrolled from the reel and made pass through said upper rollers, said facing runs of the belts, and said lower rollers, then going out of the dispenser, and to a second situation in which said upper and lower rollers are almost in contact with each other to define a condition in which the piece of paper is separated from the strip along one of said pre-cut lines located between the upper lower rollers as a consequence of pulling action due to higher speed of the lower rollers with respect to the upper rollers.
In a second embodiment there is provided a switch, subjected to elastic means placed between facing runs of the belts and set in engagement therewith, while the cover takes one or the other of two positions, namely an inoperative closing position (R) and an operative closing position (O), and a stationary blade is located in a position intermediate between the upper and lo
