1. Förfarande för framställning av en asbestfri, med glasfiber förstärkt, sammansatt cementprodukt, varvid för- 5 farandet omfattar steg för blandande av cement och vatten för bildande av en fly-tande uppslamning i en blandningsmaskin med hög skärkraft, blandande av uppslamningen med en i förväg bestämd proportion av glasfiber, 10 avsättande av den glasfiberhaltiga uppslamningen pä en för vatten genomträngbar bana, urvattnande av uppslamningen genom banan för kvarläm-nande av glasfibern och cementen pä densamma, och härdande av cementen för bildande av den med glasfiber förstärkta, 15 sammansatta cementprodukten, kännetecknat därav, att uppslamningen blandas med glasfiber i en statisk bland-ningsapparat (6), varvid glasfiber först mätäs pä den blot-tade ytan av uppslamningen medan den flyter längs en ledning i den statiska blandningsapparaten (6) och att sedan ström-20 ningsbanan (30) för uppslamningen förändras sä, att nämnda blottade yta kommer att täckas av ett väsentligen tjockt skikt av uppslamning utan användning av rörliga blad eller armar.
2. Förfarande enligt patentkravet 1, k ä n n e - 25 tecknat därav, att glasfiber mätäs pä den blottade ytan medan uppslamningen leds längs en nedätlutande ledning (20) och att uppslamningen sedan förorsakas gä over till en andra nedätlutande ledning (25), vilken riktat i motsatt riktning tili första ledningen (20) uppifrän sett, varigenom 30 strömningsbanan (30) förändras sä, att den frän början blottade ytan av uppslamningen kommer att ligga vid eller närä bottnen av flödet.
3. Förfarande enligt patentkravet 2, kännetecknat därav, att efter att glasfibern matats utförs 35 en initiell blandning medelst en väsentligen konformad stryp-
