摘要:
The invention relates to a method for connecting sheet metal parts (4) to form a laminated core (11), wherein sheet metal parts (4) are separated, in particular punched, from a sheet metal strip (2) that has, at least in some areas, a layer having curable polymer adhesive (12), and the sheet metal parts (4) are preliminarily connected to form a laminated core (11), the preliminary connection comprising plasticizing the adhesive (12) at least in some areas and joining the sheet metal parts (4) in order to connect the sheet metal parts by means of the plasticized adhesive (12) of at least one of the sheet metal parts (4), and in a subsequent step the laminated core (11) having preliminarily connected sheet metal parts (4) is subjected to a curing of the adhesive (12). In order to create an advantageous connection between the sheet metal parts, the plasticizing of the adhesive (12) comprises the introduction of a softener (16), in particular H2O.
摘要:
The invention relates to a method for bundling or strapping objects, in particular steel coils, wherein a binding tape made of a composite material comprising continuous fibers and a thermoplastic material and having a width of from 10 to 50 mm and a thickness of from 100 to 300 μm is placed around the object, in particular the steel coil, thereby forming overlapping ends of the binding tape, and in the region of the overlapping ends heat is applied to the ends of the binding tape lying one on top of the other, in such a way that the thermoplastic material softens, and pressure is subsequently exerted over the surface area of the softened region in such a way that the ends of the binding tape are pressed against each other; the invention also relates to a device for carrying out the method and to a binding tape for this.
