ABSTRACT OF THE DISCLOSURE The invention provides a cutting assembly for cutting a moving strip of thin flexible material across its width, avoiding the possibility that the flexibility of the material will permit it to move away from the knife edge and not be cut, or be cut unevenly. The assembly comprises a knife-supporting member which is engaged with the moving strip and displaces it out of its usual path close to a roll in the path, so that a very short length of the strip is between two contacting members in the path adjacent to the knife. The knife is provided along its length with a plurality of distributed strip-engaging points pointing in the direction opposite to its direction of movement, which are moved into engagement with this short supported length of the strip, so that the strip movement drives it onto the points, and thereafter continues the movement of the strip into positive engagement with the succeeding knife edges. The assembly is particularly suited for the handling of flattened tubes of plastic material as produced by a blown film plastics line, wherein the continuous strip must be cut for subsequent handling and/or storage.
