Feeding device

Apparatus for handling web material having individual images successively formed thereon and successive cut lines therein which cut lines are curved transverse to the direction of movement of the web material, said apparatus advancing and registering web material relative to a cutting mechanism which cuts the web material transverse to the advancing direction, said apparatus comprising a guide for guiding said web material to said cutting mechanism, a rotating drum spaced from said cutting mechanism and adjacent said guide, projecting elements on said rotating drum and spaced circumferentially on said rotating drum a distance substantially equal to the distance between said cut lines, said projecting elements having a surface portion extending chordally relative to said drum and beyond the periphery of said drum for engaging at least a portion of said web material adjacent said cut line and forcing at least a portion of said web material out of the plane of said web material and for projecting through said plane of said web material, said projecting elements having a further curved surface portion extending transverse to the direction of movement of the web material for engaging the edge of said web material at said cut line and advancing the web material through said guide and to said cutting apparatus, said drum being formed of plural arcuate segments having a predetermined circumference, a drive shaft on which said segments are mounted, means for securing said segments together and for removably clamping said segments on said drive shaft for rotation therewith and for removal therefrom for replacement by other segments of a different circumference when the distance between the cut lines in the web material changes, said guide for guiding the web material to the cutting mechanism comprises a pair of U-shaped lateral guide members, and means for supporting the guide members for adjustment relative to the periphery of said rotating drum to adjust the tangential relationship between the guide members and said drum when there is a change in the segments forming said drum.
