Abstract (en)
[origin: ES8402526A1] In a transverse severing apparatus for webs of thermoplastic material, two parallel pressure bars are lowerable onto and raisable from a section or sections to be severed from the web. The upstream pressure bar clamps the leading end of the web to a backing bar. The second pressure bar, which is disposed between a severing knife and the upstream bar, tensions the web clamped between a pair of feed rollers and the upstream pressure bar before the severing knife cuts the web.
