Abstract (en)
[origin: EP0382574A2] A web of material adapted to be driven through a machine by sprocket wheels having projecting sprocket pins comprises a series of main sprocket holes (2) at standard half-inch pitch and a second sprocket hole (3) located midway between each main sprocket hole. A set of radial cuts or lines of weakness (4-7) extend from each secondary sprocket hole so as to a define readily deformable zone (8) on each longitudinal side of each secondary sprocket hole and readily deformable zones (9) on each lateral side of each secondary sprocket hole. The readily deformable zones are deflected out of the plane of the web material if they encounter a sprocket hole located in the zone of but out of direct register with the secondary sprocket holes (3).
