    摘要: A cutoff, suitable for a continuous rod cigarette-making machine, and having a helical knife. To grind one side of the knife, a stationary grinding wheel inclined at the appropriate angle to grind a bevel edge on the knife is used. To grind the other side of the knife, a grinder wheel is carried by a planetary mechanism to travel in a circular path and so that, as the knife is being ground, the grinder has a motion transverse to the path of the knife.

    摘要: A PLANETARY MECHANISM IN WHICH THE PLANET MEMBER IS ROTATED BY FRICTIONAL ENGAGEMENT BETWEEN A STATIONARY ANNULUS AND A DRIVING RIM CARRIED RESILIENTLY BY THE PLANET MEMBER. UNDER STATIONARY CONDITIONS THERE IS A CLEARANCE BETWEEN THE DRIVING RIM AND THE ANNULUS. ON ROTATION, CENTRIFUGAL FORCE DISPLACES THE RIM RADIALLY RELATIVE TO THE PLANET MEMBER, SO TAKING UP THE CLEARANCE AND PROVIDING A DRIVE. IN THE STATIONARY CONDITION THERE IS NO SIDE THRUST ON THE PLANET MEMBER. THE PLANET MEMBER MAY BE A GRINDER WHEEL FOR A CIGARETTE MACHINE CUT-OFF.
