Abstract
A spreader roll that is useful to spread a slit web into a plurality of split webs for rewinding or at numerous other critical processes positions on web machines and related finishing and converting equipment. The spreader roll includes a bowable shaft and a plurality of interconnected cylinder elements mounted for rotation about the shaft. The cylinder elements each include a cylindrical outer surface and opposite end portions having nonlinear profiles to thereby provide intermittent support of the split webs as they pass over the spreader roll.
Claims14
A spreader roll for web processing machines of the type used in the paper, textile and plastics industry, for use on a web of material to be splayed, the spreader roll comprising:
- a shaft, said shaft being bowed along a longitudinal axis;
- a bowed cylindrical outer surface comprising a plurality of cylindrical elements axially aligned along said shaft, each of said elements having an outer surface and at least one end portion having a nonlinear profile;
- and
- whereby the splayed web is intermittently supported by at least one of said plurality of cylindrical elements at said nonlinear profile.
A spreader roll for web processing machines of the typed used in the paper, textile and plastics industry for use on a web of material to be splayed, the spreader roll comprising
- a shaft, said shaft being bowed along a longitudinal axis;
- a plurality of roll segments, said roll segments being bowed and rotatably supported on said shaft;
- each said segment having at least one non-linear end edge profile;
- and
- whereby the splayed web is intermittently supported by at least one of said plurality of cylindrical elements at said nonlinear profile.
