FR2557859A1 - Method for protecting the fragile edges or sides of a material or an object during handling and transport operations - Google Patents

Abstract

The object 1 whose edges must be protected is either glued definitively to a material 2 which can be cut off easily, whose resistance to cutting is less than that of the object and whose dimensions are greater than those of the object, the excess of the support having to be removed at the moment of making available or of edge-to-edge system fitting; or glued temporarily on a support material 3 whose dimensions are greater than those of the object, this support being simply unstuck at the moment of fitting, making available or of system mounting; these two methods in all cases allowing the object to regain its original or useful dimensions.

Description

PROCESS FOR THE PROTECTION OF FRAGILE EDGES OR SHORE
MATERIAL OR OBJECT, DURING OPERATIONS
HANDLING AND TRANSPORT
The present invention consists of a device intended to protect the edges or edges of fragile materials or objects, by laminating on these fragile materials or objects a material, either easily cutable or easily removable, and whose dimensions are greater than those of the object or material to be protected.

 The laminating, when it already exists, and this for reasons which can be: the stiffening of the fragile object or material, the attribution of insulating, thermal, phonic or caloric properties, or more generally the fact of conferring on the material or object a greater thickness, is generally carried out on a material of dimensions strictly similar to those of the object or the material to be laminated.

 Thus, during handling or transport operations of the fragile object or material, all possible side impacts have the effect of injuring, and the support material, and the main material or object, while surface impacts can be easily amortized using mattresses of various definitions.

 In the same way, fragile materials or objects not intended to be laminated on any support, can, during handling and transport operations, undergo side impacts damaging their edges or edges, while surface impacts can be easily amortized using mattresses of various definitions.

 The present invention stipulates that, when the fragile material or object (i) must be permanently laminated on another material (2) conferring on the former qualities of stiffening, insulation or thickening, the support material must be able to be cut out easily, using sharp, cutting or eroding tools, such as plains, baguette saws, knives or cutters, fine rapes, planes, etc ... and that this support material must have a lower cutting resistance to that of the object or material to be laminated. The support material having dimensions larger than those of the material or object to be laminated (FIG. 1), it is this former which will absorb all lateral impacts during handling or transport operations.

 The overflow of the support material must be calculated in such a way that normal lateral impacts only enter this projecting part. For example, support materials such as gypsum board, plastics or semi-rigid rubbers, should protrude by about 15 millimeters, while more flexible materials, such as foams, expanded polystyrene, etc. protrude at least 30 millimeters. If the support material proves to be too flexible or too fragile to absorb lateral impacts, it will be necessary to resort to the second method, described below, which relates to the temporary lamination of fragile materials and objects.

 During assembly, installation, or commissioning of the fragile material or object thus laminated, the. protruding part of the support (3) will be removed, by cutting or planing, at a bevel or at any useful angle (FIG. 2), this operation having the aim of restoring the fragile object or material to its original or useful dimensions.

 If the material or object whose edges are to be protected is not intended to be laminated on any support material, the protection of its edges or edges will be ensured by a temporary laminating, on a material which could, possibly, be a resistance greater than that of the object, and whose dimensions will be larger than those of the object or material to be protected (Figure 3).

 During assembly, installation, or commissioning. of the object or material thus laminated, the support will be purely and simply peeled off (FIG. 4), the peeling process depending on the qualities of the bonding: by dipping in water, or any solvent, of the glue used, by draw when using magnetic strips, and so on.

 The two devices described above are more particularly intended for objects and materials to be mounted in a system, edge to edge, or to be embedded, without joints or frames, such as panels and tiles.

Claims (3)

1) Method for protecting the edges or edges of fragile objects or materials during handling or transport operations, characterized in that the material or object is laminated to a support material of larger dimensions than those of the object or laminated material, and the overflow of the support, or the entire support, is then removed. 2) Method according to claim 1, characterized in that the support material (2), depending on whether it is permanently laminated or not on the material or object to be protected (1), must be either easily cut with using sharp, cutting or eroding instruments, as well as less resistance to cutting than  the protected object, in the first case, is easily removable in the second. 3) Method according to the two preceding claims, making it possible, in all possible cases, to restore the object or the material to be protected to its original dimensions, after cutting off the excess of the support (3), for placing use, edge-to-edge system layout, installation or embedding.
