<p>A device for the longitudinal cutting of webs comprises two hollow shafts, each bearing a blade, and supported on a respective spindle. One spindle is supported eccentrically in a frame so that its rotation sets the inter-axis spacing of the two shafts, whereby the blades may be engaged and disengaged in the radial sense. The same spindle is displaceable axially whereby the blades may be engaged and disengaged in the axial sense. Both operations are performed by means of one and the same handle. Means is also provided for displacing simultaneously both spindles in the axial directions in order to position the blades relative to the web.</p> |
