<p>An apparatus for severing (collar) blanks from a web of material is disclosed. Knife rollers (10) which are provided with knife edges (17) are used to sever blanks of (thin) cardboard from a web. A knife roller (10) is pressed against a counter roller (11). For this purpose, there are provided resiliently adjustable pressure elements (30). The pressure is exerted on the counter roller (11) in the region of annular supporting elements, in particular annular rims (18). The annular rims (18) for exerting pressure are designed such that they are slightly resiliently compressible in the region of contact with the counter roller (11). For this purpose, the annular rims are especially designed to be Z-shaped in cross section.</p> |
