• the invention relates to a device for applying a wide flexible band to a surface to be covered; it relates more particularly to a simple device for applying a weakly adhesive film on a surface to be protected, especially a flat surface.
• wide flexible band is meant a strip of more than 10 cm (typically between 15 and 60 cm, or even more, up to 100 cm) which, when packaged in a reel, is not susceptible to to be carried by a unpacker sufficiently compact and light to be used with one hand.
• the patent application US 2005/0028941 discloses an apparatus for applying such a flexible band called "wide" packaged in a coil.
• the apparatus is more particularly designed to cover a floor, possibly the steps of a staircase. It comprises for this purpose a carriage carrying the reel and a system of rollers. The carriage is moved using an articulated handle.

• said support may advantageously comprise two actuating elements projecting from the casing in the vicinity of the aforementioned end walls.
• the device comprises a flexible tongue integral with the housing and projecting outside thereof, in the vicinity of the applicator roll, parallel to the latter.
• each pin has the shape of a shoulder bushing mounted in a hole made in a corresponding end wall of said housing. Said pin is engaged in an end of said mandrel which is cylindrical and tubular.
• each pin is frictionally engaged in said corresponding end wall and said tubular mandrel is mounted for free rotation between the two journals.
• the device may comprise two aligned guide rollers, respectively mounted on the aforementioned end walls of said housing, parallel to said application roller.

• the casing 11 comprises an upper wall 17, a rear wall 18 and a bottom wall 19. These three walls can be obtained by a sheet folded twice at right angles.
• the housing is completed by two end walls 21, 22. It is open over its entire length between these walls, to allow unwinding of the flexible strip and its application on any surface, for example a vertical wall 25, as shown in Figure 2.
• the flexible strip may be a weakly adhesive film, known per se.
• the housing is equipped with two journals 27, 28 aligned to define an axis of rotation X of said coil. These two pins are respectively carried by the two end walls 21, 22, to support the mandrel 15.
• the housing also carries an applicator roll 30, arranged parallel to the aforementioned axis of rotation X.
• This applicator roll is rotatably mounted between the two end walls 21, 22.
• the housing also houses a cutting mechanism 34 of said strip.
• this cutting mechanism 34 comprises a blade 37, possibly provided with teeth, the length of which corresponds to the width of the flexible strip to be cut.
• This blade is secured to a support 39 mounted movably in the housing, in a direction perpendicular to the axis of rotation X of the coil, defined by the two journals. More specifically, the support 39 is slidably mounted at its two ends in slides located in the vicinity of the two end walls 21, 22.
• the support 39 carries two actuating elements 41 constituted here by two pushers protruding from the casing in the vicinity of said end walls 21, 22.
• the upper wall 17 has two slots 43 in which said displacers move. tappets.
• the support 39 is urged back inside the housing by elastic means 45 such as springs mounted in tension between the pushers and the end walls.
• each pin 27, 28 is in the form of a shoulder socket mounted in a hole 47 in a corresponding end wall.
• the trunnion (more particularly the part of smaller diameter of the sleeve) is engaged in one end of the tubular mandrel 15.
• each trunnion is engaged with moderate friction in the corresponding end wall 21, 22 while the tubular mandrel 15 is mounted for free rotation between the two journals.
• the hole in the socket has a diameter sufficient to engage one or two fingers and a length small enough for the user to brake the chuck tubular 15, from the inside, during the unwinding of the flexible strip 14.
• the coil change is done in a simple manner by releasing the pins 27, 28.
• the device further comprises a flexible tongue 49 (for example of elastomer) integral with the housing, more particularly fixed to the upper wall 17.
• the tongue 49 protrudes outside the housing over substantially the entire length thereof and at the neighborhood, that is to say above the applicator roller 30, parallel to the latter.
• the cutting mechanism 34 is between the applicator roll 30 and the flexible tongue 49.
• the applicator roll is lined with an elastically deformable material 50 of notable thickness, of the order of 5 mm or more.
• An elastomeric material known as a nitrile with a hardness of 30 shores has given satisfactory results.
• the device is completed by two guide rollers 53, 54, relatively short and small diameter, aligned, respectively mounted on the end walls 21, 22 of the housing, parallel to the applicator roll 30 and below thereof.
• the two guide rollers project into the housing near the opening thereof, as can be seen in FIG. 1.
• These two guide rollers 53, 54 are advantageously made of flexible material.
• Each guide roller is freely rotatably mounted on a corresponding end wall.
• the unrolled web of the spool is in contact with the applicator roll 30 and passes over the guide rollers 53, 54.
• the short length of the guide rollers and their flexibility facilitates the positioning of the film in unwinding position. When the band is cut, the portion attached to the coil 13 falls and is held by the two guide rollers in a position facilitating the unwinding of a new lé.

• the flexible band (the adhesive film) passes between the applicator roll 30 and the guide rollers 53. It is in contact with said applicator roll.
• the blade 37 is retracted inside the housing. The user holds the housing 11 at both ends. By engaging his fingers in the two sleeves forming the pins 27, 28 maintaining the coil inside the housing, it can control the unfolding of the flexible band.
• the user can grind the flexible strip 14 on the surface to be covered as it unfolds, exerting a uniform pressure across the width thanks to the applicator roll 30.
• the user rotates the applicator device to move the applicator roll 30 away from the wall while maintaining a certain tension on the flexible band by means of the flexible tongue 49 which remains applied against the wall .
• the user With its thumbs, it simultaneously presses the two actuating elements 41, which causes the movement of the blade towards the flexible band 14 and the sectioning thereof.
• the end in contact with the application roller falls by gravity and is held by the two guide rollers 53; the user can then easily place this free end in contact with the flexible tongue, for the application of a new le.
