Abstract:
1. Machine for constructing a composite box, the machine comprising: a conveyor system for transferring a sheath, which has been pre-assembled at a forming station, which sheath is transferred with its repository; a storage site for storing tray cutouts; means forming extractor arms for picking up said tray cutouts one by one in said storage site and bringing them to a repository, at the level of an assembly station, opposite said sheath; means for applying glue to the edges of the longitudinal sides of the sheath and the flanks of the tray cutout as they are moving toward said assembly station; a portal frame that is arranged transversally above said conveyor system, in the median vertical plane of said assembly station, which portal frame, in the form of a beam, comprises two mobile structures: means arranged on the matrix in order to press said flanks of the tray cutout on said sheath and press-type means, which press is arranged on the supporting structure of said push member, upstream of the latter, and penetrates to the end of said sheath in order to maintain, with suitable actuator-type means, a counter-pressure opposite the pressing means in the form of actuators arranged on the matrix.
