Definitions

• the subject of the present invention is an automatic application and printing device for a strip of gummed paper.
• the term "gummed paper” means any cellulosic support in a strip provided with a layer of dry adhesive which, once wet, regains its tackiness.
• Many portable dispensers are known which make it possible to distribute and apply portions of adhesive tape from a very long roll on various types of product, but more generally on cardboard boxes so as to ensure their closure.
• These adhesive tapes are made using a very thin support layer coated on one side with an adhesive suitable for sticking to the receiving surface. Such an assembly is satisfactory but has the drawback of using adhesives on a polymer support while industrial trends are moving towards products which are completely recyclable from natural materials.
• This gummed paper is made from a paper tape, one side of which is coated with an adhesive. which, when dry, does not stick to the paper and which has a strong adhesive power as soon as it has been moistened. The taking can then be carried out almost instantaneously. Indeed, the very small amount of water absorbed by the glue diffuses from the application in the thickness of the paper tape which absorbs part of it while the other part is absorbed directly by the cardboard of the box which receives it. .
• the first problem is therefore to moisten this strip of gummed paper with the aid of a saturated humidifying element, avoiding - of course - any untimely flow of water which would wet the dispensing apparatus, which would make it unpleasant to handle or more serious still which would wet the roll of gummed paper, because in this case the ribbon would stick on itself, and would make it permanently unusable.
• the dispenser is portable and it should not be excessively heavy so that the humidifier assembly must be integrated into said dispenser.
• This humidifying device should also be removable so as to allow it to be changed regularly due to wear.
• the distributor must have an easily refillable reserve of water from a tap, a bottle or any other container.
• the system must be robust, taking into account the conditions of use and otherwise reliable since it is generally used with high rates.
• the present invention meets the requirements set out above and also makes it possible to work in all positions, because it is known that this type of device is held substantially horizontal in the waiting position but that it has returned to the working position, constantly undergoing rotations.
• the application device according to the invention also accepts different lengths of rollers having mandrels of different diameters and this also with variable widths.
• Adhesive tapes made of polymer material are generally pre-printed with a special mention. However, the printing of mentions on adhesive tapes is expensive because it requires sophisticated equipment and must be carried out during the manufacture of the adhesive roll. On the other hand, large quantities must be ordered to absorb the material used for printing.
• the present invention provides, in combination with the portable dispenser, an automatic device for printing the strip of gummed paper, at the time of application using this portable dispenser, simultaneously with the application of the strip of gummed paper on the cardboard box. Immediate advantages arise from this automatic printing and in particular the fact that stocks are eliminated, since it suffices to have different printing matrices, the support being identical whatever the mention given since it is always acts of rolls of blank gummed paper.
• the device for applying a strip of gummed paper comprises a dispensing support with a handle, a mandrel holder with at least one applicator cylinder, humidifier means comprising a housing open on a face to receive a felt projecting from this face and designed to cooperate by friction with the adhesive face of the strip of gummed paper and a tank filled with water, characterized in that it comprises a first and a second duct connecting the receiving housing the felt to the water reservoir, the first conduit being shorter than the second and arranged so that the first and second conduits open at their ends into the reservoir respectively at the bottom of this reservoir and above the free surface of the water contained in the tank, that is to say at both ends of the tank.
• the first and second conduits both open at the rear of the housing.
• the first conduit opens behind the felt, in the housing, on the face opposite to the open face and the second conduit extends inside the felt to the immediate vicinity of the projecting part.
• the two conduits are coaxial.
• the handle is hollow to form the reservoir and comprises a tight cover by interlocking at its lower part and transparent so as to allow visualization of the water level contained in the reservoir.
• the chuck holder of the application device according to the invention comprises width adjustment means, more particularly by means of two arms mounted movable in rotation and in translation on a transverse axis and provided with return means. elastic compensation.
• the dispenser support includes a removable reducer designed to cooperate with the support and provide guidance with narrower strips of paper.
• the blade is held in a removable transverse bar provided with a lateral opening for introducing the base of the blade.
• the application device is further characterized in that it comprises means for automatic and simultaneous printing of the strip of gummed paper applied, these printing means comprising an element in relief carried by the application cylinder and coming into contact on the one hand with the ink pad and on the other hand with the non-adhesive face of the strip of gummed paper during each rotation.
