ABSTRACT:
A bursting apparatus for separating one or two continuous webs of material along transverse lines of weakening thereon. The material is fed through two pairs of rollers driven by suitable driving apparatus. Magnetic clutch and magnetic brake assemblies halt rotation of one pair of rollers upstream the transverse line of weakening, while the other pair of rollers continues to grip and feed the material. The resultant longitudinal tension along the material promotes rupture at the transverse line of weakening. A breaker roller mounted between the two pairs of rollers has axially mounted spheres to promote discrete points of increased tension along the transverse line of weakening. The bursting operation is repetitive and continuous. Separated sheets are successively transported or stacked after passing through the rollers.
