摘要: A tandem arrangement of diecutting rolls severs scrap from a traveling web in two steps, each of which steps effects cutting entirely through the web, but at different peripheral locations. The partially cut scrap is carried with the remainder of the web from the first roll to the second, and any severed piece that lodges within the cutting element of the second roll is removed by the action of a mechanical scraper, which passes therethrough.

摘要: A die-cutting roll is constructed to cut holes in traveling web materials, and for clearing and discharging the fragments, in a highly effective manner. A multiplicity of air vent ports communicate with the channel through which the scrap moves to an internal axial passage of the roll, and supplement the effect of vacuum applied to one end thereof. Desirably, a disuniting effect is produced upon compacted formations strands of the removed material, by creating turbulence within the passage and/or by mechanical impact thereupon.
