Patent ID: 7909282

Claim:
An apparatus for breaking a moving web comprising: a conveying surface over which a moving web is conveyed; a first rotating arm configured to rotate about a first axis, and a second rotating arm configured to rotate about a second axis, wherein the first and second arm are positioned adjacent to the conveying surface, the first rotating arm being spaced upstream from the second rotating arm with respect to a moving web, the first rotating arm defining a first contact surface that contacts the conveying surface when the first rotating arm is rotated, the second rotating arm defining a second contact surface that also contacts the conveying surface when the second rotating arm is rotated; 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, and wherein the first and second axis respectively and the conveying surface are at a fixed position relative to one another and remain at said fixed position relative to each other at all times during conveying of the web such that the first rotating arm and second rotating arm are configured to contact and break the moving web with each full revolution about the first and second axis respectively.
