The invention relates to a method of producing a product comprising a support having a long-acting adhesive and a protective tape disposed thereon, so that said adhesive can be used at a later time. The inventive method is characterised in that it consists in: determining a reference plane (P) which is close to the location of the adhesive deposit and which is either below the plane containing the lower face of the support or above the plane containing the upper face of said support; establishing the distance (D) separating the reference plane (P) and the level (N) at which the adhesive (2) is delivered, which is close to the plane containing the application face of the support; delivering the long-acting adhesive (2); delivering a protective tape (20) which is disposed on top of the adhesive (2) either simultaneously using a prefabricated transfer tape or separately; moving the support in relation to the deposit station; exerting a transverse force on the support such that one of the faces thereof is applied continuously against the reference plane (P); and exerting a pressure, counter to the transverse force, on the protective tape (20) and the adhesive (2).
A method for manufacturing a product consisting of a support on which there is a long-acting adhesive and a protective tape for delayed use of said adhesive, for joining by means of said adhesive two elements of the support, one of which bears a surface known as the “application” surface and the other of which bears a surface known as the “destination” surface, which method consists in bringing about a relative movement between said support and a station for the coordinated deposition of an adhesive and of a removable protective tape, preferably by moving the support and not the deposition station, then in applying to the application surface, from the deposition station, long-acting adhesive either in the form of a prefabricated assembly comprising a base, long-acting adhesive and a removable protective tape, or in the form of two successive applications of an adhesive alone and then of a removable protective tape alone, characterized in that:
A device for manufacturing a product consisting of a support on which there is a long-acting adhesive and a protective tape for delayed use of said adhesive, for joining by means of said adhesive two elements of the support, one of which bears a surface known as the “application” surface and the other of which bears a surface known as the “destination” surface, this device comprising:
A product, in particular a fibrous product, which consists of a part made of cardboard, corrugated cardboard or a similar material, such as a simple panel, a cut preform which is grooved and optionally printed which may have folded and glued parts, or else a volume article such as a container, characterized in that this part has at least one slightly adhesive tape (20) arranged on top of a bead of long-acting adhesive (2) applied to at least a first element of the part which forms a zone known as the “application zone”, in the presence of which there is to be located, after folding and/or partial straightening, a second element of the part along a face known as the “destination surface” without adhesive (2) and thus protective tape (20), this destination surface having greater adhesive (2) retention power than that of the rest of the part.
