Abstract
Apparatus for cutting which involves the adjustment of height of the cutting blades in a rotating cylinder through the use of cooperating tapered surfaces on two components of a blade supporting bar.
Claims9
Apparatus for cutting web material comprising a frame, a blade roll rotatably mounted on said frame, an impression roll rotatably mounted on said frame adjacent said blade roll,
- said blade roll being equipped with an axially-extending slot having a radially inward generally circumferentially-extending bottom wall and spaced generally radially-extending side walls,
- blade-supporting bar means mounted in said slot having a bottom wall adjacent said slot bottom wall, said bar means being equipped with generally circumferentially-extending integral ledge means adjacent said bar bottom wall, and
- a blade mounted on said ledge means and interposed between said bar means and one sidewall of said slot,
- said bar means including axially extending generally chordally disposed ramp means for adjusting the blade height relative to said impression roll, said ramp means including cooperating surfaces which extend axially and are movable axially relative to one another to support said bar means for radial movement without substantially affecting clamping of said blade by said bar means.
Apparatus for cutting web material comprising a frame, a blade roll rotatably mounted on said frame, an impression roll rotatably mounted on said frame adjacent said blade roll,
- said blade roll being equipped with an axially-extending slot having a radially inward generally circumferentially-extending bottom wall and spaced generally radially-extending side walls.
- blade-supporting bar means mounted in said slot having a bottom wall adjacent said slot bottom wall, said bar means being equipped with generally circumferentially-extending integral ledge means adjacent said bar bottom wall, and
- a blade mounted on said ledge means and interposed between said bar means and one sidewall of said slot,
- said bar means including axially extending generally chordally disposed ramp means for adjusting the blade height relative to said impression roll, said bar means including two component parts having engaged tapered surfaces providing said ramp means, said component parts being equipped with rack and pinion means to incrementally adjust blade height.
Apparatus for cutting web material comprising a frame, a blade roll rotatably mounted on said frame, an impression roll rotatably mounted on said frame adjacent said blade roll,
- said blade roll being equipped with an axially-extending slot having a radially inward generally circumferentially-extending bottom wall and spaced generally radially-extending side walls,
- blade-supporting bar means mounted in said slot having a bottom wall adjacent said slot bottom wall, said bar means being equipped with generally circumferentially-extending integral ledge means adjacent said bar bottom wall, and
- a blade mounted on said ledge means and interposed between said bar means and one sidewall of said slot,
- said bar means including axially extending generally chordally disposed ramp means for adjusting the blade height relative to said impression roll, spring means being operatively associated with said blade roll bearing against said bar means for exerting a generally circumferential force against said bar means to clamp said blade, a resilient base being provided in said slot to permit exertion of a radial force against said bar means.
