APPARATUS AND METHOD FOR BREAKING A WEB

摘要

An apparatus (60) for breaking a moving web comprissing: a conveying surface (3Od) over wich a moving web (3S) is conveyed; a first rotating arm (306) and a second rotating arm (308) positioned adjacent to the conveying surface, the first rotating arm (306) being spaced upstream from the second rotating arm with respect to a moving web, the first rotating arm defining a first contact surface (310) that contacts the conveying surface (300) when the first rotating arm is rotated, the second rotating arm defining a second contact surface (312) that also contacts the conveying surface when the second rotating arm is rotated; and wherein, in order to break a moving web on the conveying surface,both rotating arms are rotated causing each of the respective contact surfaces to contact the moving web on the conveying surface at or near the same time, the second rotating arm being configured to rotate at a speed faster than the first rotating arm during contact with the moving web causing the moving web to break in between the first and second contact surfaces.
