ABSTRACT:
A transverse cutter for a running web of paper or the like has two rotary drum-shaped holders disposed opposite each other at the opposite sides of the path for the web. Each holder carries at least one knife with an elongated cutting edge extending transversely of the path of movement of the web, and each knife of one holder cooperates with a knife of the other holder to sever the web once during each revolution of the holders. One of the knives is adjustable with reference to the respective holder so that its cutting edge can be shifted relative to the cooperating cutting edge of the other knife. The adjusting mechanism for the adjustable knife includes a row of closely adjacent wedge-like retainers which are recessed into the peripheral surface of the respective holder and are movable radially of such holder by threaded fasteners which can move the associated retainers radially inwardly against the opposition of dished springs in the respective holder. Each retainer has a projection which engages one side of the adjustable knife midway between the cutting edge and the innermost portion of such side. The other side of the adjustable knife bears against a second row of wedge-like retainers which are recessed into the respective holder and have projections bearing against the innermost portion of the other side of the adjustable knife. Such mounting allows for at least some elastic flexing of the adjustable knife.
