Abstract
The invention relates to a method, a device and packaging obtained by way of the method, for fitting at least one reinforcement at a given location on a cutout of cardboard sheet or corrugated cardboard suitable for forming the packaging. The blank is removed from a store with the aid of unstacking means comprising a longitudinal structure with a given shape, the blank is transferred horizontally above a template for forming said blank, the blank is compressed between the template and said longitudinal structure, the blank thus configured is transferred with glue being applied to the side edges and the blank thus glued is applied to the cutout at the given location so as to form the reinforcement of said packaging.
Claims19
A method for fitting at least one reinforcement at a given location of a cardboard or corrugated cardboard sheet cutout, which can form packaging provided with walls with a given height, the at least one reinforcement being obtained from a cardboard or corrugated cardboard blank with a length equal to said given height, comprising:
- extracting the blank from a store by grasping it by aspiration using unstacking means comprising a longitudinal structure with a given form, designed to be placed above the blank thus grasped in the direction of the length of the blank;
- transferring the blank horizontally above a template for forming of said blank with a form which is at least partly complementary to said given form;
- compressing the blank between the template and said longitudinal structure, in order to provide part of the blank with said given form, and form horizontal longitudinal lateral edges;
- transferring the blank thus configured whilst gluing the lateral edges;
- and
- applying the blank thus glued on the cutout in the given location, in order to form the reinforcement of said packaging.
A device for fitting at least one reinforcement in a given location of a cardboard or corrugated cardboard sheet cutout which can form packaging provided with a wall with a given height, the reinforcement being obtained from a cardboard or corrugated cardboard blank with a length equal to said given height, comprising:
- means for gripping the blank in a store by aspiration, comprising unstacking means comprising a longitudinal structure with a given form, designed to be placed above the blank thus grasped;
- a template for forming said blank with a form which is at least partly complementary to said given form;
- means for transfer of the blank horizontally above said forming template, compression of the blank between the template and said longitudinal structure in order to provide it partly with said given form, and to have horizontal longitudinal lateral edges, and transfer of the blank thus configured opposite the cutout in the given location;
- and
- means for gluing the lateral edges and pressing the blank thus glued on the cutout in order to form the reinforcement of said packaging.
A packaging made of cardboard or corrugated cardboard sheet material in the form of a box with a polygonal cross-section comprising lateral walls with a given height, an upper wall which forms a lid, and a lower wall which forms the base of the box,
- comprising at least one reinforcement obtained from a cardboard or corrugated cardboard blank with a length equal to, or substantially equal to, said given height, said reinforcement being arranged in the direction of the height of the box, on an inner face of the packaging, and having a central part with a transverse cross-section in the form of an inverted “V” or “U”, and two longitudinal lateral edges glued on said inner face, which edges are entirely spaced from the junctions with the adjacent lateral walls.
