ABSTRACT:
A web-cutting arrangement uses two-stage cutting to produce a plurality of products from a continuous web (100), while ensuring that the web, and the products (125) cut therefrom, remain continuously guided and undamaged. The arrangement includes a leading cutting structure (170) which provides an initial partial cut (115) into the web. The partial cut (115) is made along a line (110) directed perpendicular to the web length, leaving a remaining uncut portion (120) along the line (110). Using web transport belts (140) located so as to overlap the cutout (or partially cut) portions of the web (100), the continuous web is moved in a direction parallel to the web length with the belts (140) pulling and guiding the web (100) around rotating cylinders (164, 166). A downstream cutting structure (180), having knife edges (210, 212, 214), is located and arranged adjacent but not interfering with the web-guiding belts (140) to cut the remaining uncut portion of the web along the same line (110), while the web-guiding belts (140) are guiding the web (100). An additional feature addresses situations in which the downstream cutting structure (180) would otherwise cut at the wrong place, i.e., not exactly along the same line where the partial cutout is provided. This problem is eliminated by providing a controlling mechanism (190) to adjust the point at which the cutting structure (180) contacts the continuous web (100) to finish the cut.
