Fire-resistant or fireproof laminate.

摘要

A fire-resistant or fireproof laminate (86) is produced from a non-extrudable core mixture (24) with a pourable, fireproof filling material and a binder, and covering bands adhesively bonded elastically to the core on both sides. …For a continuous production of the laminate (86) in one operation, the core mixture (24) is poured onto an elastic lower adhesive film (16), supported as it runs in, and a pile extending over the entire width is formed there. Between the elastic lower adhesive film and an elastic upper adhesive film (30), likewise supported as it runs in, material of the core mixture (24) is continuously and uniformly drawn through a wedge gap (40) and for the first time compressed and calibrated to thickness there. The adhesive films (16, 30) containing the precompressed core mixture (24) are bonded to the continuously fed-in covering bands. …The apparatus for carrying out the process comprises a spreader roll for each of the adhesive films (16, 30), a device for uniformly applying the core mixture (24), first means for forming an adjustable run-in angle ( beta ) and the wedge gap (40), second means for supporting the lower adhesive film (16) and third means for final pressing and heating, as well as a cutting-to-length device. ……
