Abstract: There is provided a knife-ring remover for chips having a knife ring arranged rigidly on an axis. The knife ring has a collar of knives and first and second bearing rings concentric to the axis. A housing, that partly encloses the knife ring, has a rear wall, an essentially cylindrical sheath and a door disposed opposite to the rear wall for driving out a rotor. The rotor has a pair of front walls that bear a plurality of blades. The rotor is mounted in a rotatable manner on the axis. First and second abrasion sealing rings are disposed in the regions of the first and second bearing rings. Each abrasion sealing ring has an inner axial edge that lies at least approximately in the same plane perpendicular to the axis as an axial inner edge of the corresponding bearing ring. One abrasion sealing ring is connected to the door and the other is attached directly or indirectly to the rear wall.

Abstract: An apparatus for milling the surface of low slope substrate has a milling device, such as a saw, and a track along which the milling device may move. The track is supported above the substrate by a plurality of adjustable supports which have adjustment means for orienting the track vertically or at a desired angle to horizontal. A mounting assembly for the milling device has means for engaging the track and enabling movement of the assembly along the track with the milling device depending from the mounting assembly. Adjustment means coact with the milling device and the mounting assembly enabling the device to be oriented in a desired manner relative to the substrate.

Abstract: A circular cylindrical bearing section for a die cutter blanket comprises two segments pivoted relative to each other at one interface therebetween and resiliently urged radially apart by spring plungers at a second interface therebetween. A blanket section is wrapped about the two segments which are resiliently urged against the overlying blanket section secured to the bearing section by a conventional channel in the bearing and mating male-female interlocking members on the blanket. An array of bearing-blanket sections on an anvil roll are axially coupled by annularly spaced mating pins and notches at opposite axially facing edges of the bearing sections. The array of bearing-blanket sections are selectively slid as a unit along the anvil roll to rapidly relocate the blanket sections to minimize local blanket wear. The interlock members of each blanket section may be misaligned axially with the respect to the interlock members of the adjacent blanket sections.
