Description

NOTICE OF SUBSEQUENT PATENT APPLICATIONS

This application claims the priority of Italian Patent Application No. 102018000005049 , filed May 3, 2018, to which reference is made.

The present invention relates to a bandage for gluing panels of wood or the like.

In particular, the invention relates to a banding group of the type comprising a banding station for joining a band and a panel; a printer positioned in the cover band for stabilizing the cover on the panel; a cutting device for cutting the edge band; a magazine for a plurality of wrappings of edgebands; and a feed unit for feeding the cover of the magazine to the Umleimgruppe. The feed unit, in turn, generally comprises a guide means which in turn comprises a plurality of flanking feed channels for slidingly guiding respective edge strips and, for each feed channel, a corresponding pair of driven runners.

The cover-laying group further comprises a gumming device for applying adhesive to the cover and / or an activator for activating a heat-melting layer of the cover.

Known Umleimgruppen the above type have some disadvantages, which are mainly due to the fact that each edge strip after its rolling from the respective winding has a curvature that can affect the correct feed of the edge band in the corresponding feed channel of the guide device, the correct sticking of the Edge banding on the board, as well as the correct finishing of the edge band.

The invention has for its object to provide a ply for gluing panels made of wood or the like, which does not have the disadvantages mentioned above and is easy and economical to manufacture.

According to the present invention, there is provided a banding group for gluing panels of wood or the like as claimed in the appended claims.

1 shows a bandage group 1 in their entirety for the gluing of boards 2 of wood or the like, substantially planar, each panel being of substantially parallelepiped shape bounded by two larger surfaces 3 that run parallel to each other, and inter alia, from a lateral extent 4 which is essentially transverse to the surfaces 3 runs.

The bandage group 1 has a feeder 5 for successively advancing the panels 2 through a repatriation station 6 on, accordingly, at least part of the circumference 4 every blackboard 2 , from a corresponding lipping 7 is lined.

The bandage group 1 includes, among other things, a magazine 8th for a plurality of coils 9 of bandages 7 ; a printing unit 10 , mounted according to station 6 for stabilizing each edge band on the circumference 4 the panel concerned 2 ; and a feed unit 11 for advancing the edge band 7 from the magazine 8th to station 6 ,

device 10 comprises at least one pressure roller 12 around a substantially vertical longitudinal axis 13 circulates.

unit 11 includes a guide device 14 between the magazine 8th and the station 6 is mounted and in turn a plurality of feed channels 15 includes, the lappers between them 7 lead smoothly. Facility 14 includes among other things for each channel 15 a corresponding pair of feed rollers 16 at the entrance of the canal 15 arranged and driven to the lipping 7 from the respective winding 9 unroll.

The bandage group 1 includes, among other things, a rubber device 17 upstream of the printing unit 10 in the feed direction 18 of the edge band 7 from the magazine 8th to the station 6 is arranged. It's a rubber roller 19 provided that around an axis 20 parallel to the axis 13 runs around to apply glue to the edge band.

According to a variant not shown, the banding group comprises 1 an activator for activating a heat-fusible layer of the edge band 7 , The activator can be used instead of the rubber device 17 only on the rubber device 17 be arranged, adapted to the Umleimgruppe 1 to different types of edgebands 7 correspond to.

According to the 2 and 3 is the banding group 1 also with a unit 21 for straightening and reducing the curvature of the edge band 7 provided from time to time by the respective winding 9 the station 6 is supplied. The unit 21 to straighten can between the magazine 8th and the guide device 14 and the printing unit 10 be arranged, in particular between the guide device 14 and the gummi device 17 , device 21 includes a plurality of rollers 22 for straightening. These are on the opposite side of a feed path P of the edge band 7 across the device 21 arranged; they are about a respective axis of rotation 23 parallel to the axes 13 and 20 arranged.

The roles 22 are arranged according to an alternating sequence along the path P. In other words: axis 23 every role 22 is in relation to the axis 23 the adjacent role in the direction 18 offset and arranged on the way P opposite side with respect to axis 23 the adjacent role 22 ,

The way P includes a curved entrance section 24 and a substantially rectilinear exit section 25 , arranged in a boundary plane C parallel to the axes 23 , These are at a distance D from the boundary plane C arranged, increasingly in the direction 18 , device 21 includes, among other things, a pair of driver rolls 26 that are downstream of the rollers 22 in the direction 18 are arranged. They are driven to run around corresponding axes of rotation parallel to each other and to the axes 23 ,

According to a variant, not shown, the rollers 26 omitted, and at least part of the roles 22 is powered to the lipping 7 through the device 21 pass therethrough.

The bandage group 1 includes, among other things, a heater 27 located upstream of the rollers 22 in the direction 18 to the lipping 7 to heat up and accurately straightening the part of the rollers 22 to facilitate.

device 27 In the exemplary embodiment comprises two blowing systems 28 , on both sides of the way P mounted, for supplying warm air to the lipping 7 , According to further embodiments, not shown, the blowing systems are omitted and replaced for example by heating rollers or heating lamps.

The presence of the device 21 for straightening guarantees the correct advancement of the lipping along the feed channels 15 the management facility 14 , the correct attachment of the edge band 7 at the extent 4 the boards 2 as well as the correct final editing of the edge band 7 ,
