Abstract
The cutting device (1) for a continuous material, in particular a corrugated web, consists of rotating paired cutter bars (5, 6) mounted in bearings above one another, with blades (8) which run in the lengthwise direction of the cutter bars. Each cutter bar (5, 6) is connected directly with a driving motor (10) on each end (9). A synchronizing device (11, 12, 13) for the cutter bars (5, 6) is present. FIG. 1 is the main illustration.
Claims8
A cutting device for cutting a continuous sheet of material, the cutting device comprising:
- (a) a first elongated cutter bar mounted for rotation about its longitudinal axis and carrying a longitudinally mounted and radially extending first blade;
- (b) a second elongated cutter bar mounted for rotation about its longitudinal axis and carrying a longitudinally mounted and radially extending second blade, the second cutter bar extending substantially parallel to the first cutter bar and being spaced apart from the first cutter bar;
- (c) a synchronizing arrangement for synchronizing the rotation of the first cutter bar about its longitudinal axis with the rotation of the second cutter bar about its longitudinal axis so that the first blade passes the second blade generally in a plane of the material to be cut, the first blade and second blade cooperating as they pass each other to provide a cutting action there between;
- (d) a first drive motor connected to drive the first cutter bar at a first end thereof and a second drive motor connected to drive the first cutter bar at a second end thereof;
- and
- (e) a third drive motor connected to drive the second cutter bar at a first end thereof, and a fourth drive motor connected to drive the second cutter bar at a second end thereof.
