VORRICHTUNG UND VERFAHREN ZUM VERBINDEN VON ZWEI DÜNNEN MATERIALBAHNEN

摘要

In a device for splicing two thin film web portions (5, 6) comprising a roll supplying a web of film material, a roll for winding a web of film material and a splicing table (2) adapted to be subject to sub-atmospheric pressure and having a first groove (3) therein defining a cutting line and means for applying a splicing tape (9) to unite said first and second webs of film, the splicing table includes a second groove (4) that is parallel to the first groove, both grooves being perpendicular to the longitudinal direction of the webs of film, the vacuum table being thus split into three regions each individually adapted to be put under sub-atmospheric pressure, the device being useful for highly accurate splicing of webs of ultra-thin film material.
