Claim 11

The rotor assembly defined in claim 8, wherein said channel is of dovetail shape and each of said spacer elements is a similarly shaped block.

Claim 12

The rotor assembly defined in claim 8, wherein one of said end surfaces is provided with a plurality of parallel grooves and each knife blade is a plate-like member having a rib adapted to seat in one of said grooves for selecting the degree of projection of the knife blade from the rotor periphery.

Claim 13

The rotor assembly defined in claim 6, wherein means is provided for exerting a force longitudinally of each channel to increase the clamping pressure of said spacer elements on said knife blade elements.

Claim 14

The rotor assembly defined in claim 6, wherein at least one end of each channel is open, and a clamping ring is removably mounted on that end of the rotor to close said channel ends and retain the spacer elements and knife blades in clamped assembly in said channEls.

Claim 15

The rotor assembly defined in claim 6, wherein said spacer elements have opposite parallel planar knife blade contacting and holding end surfaces that are inclined transversely of the channel and also similarly inclined toward one end of the channel, and said knife blades are flat-sided members clamped between the end surfaces of adjacent spacer elements.

Claim 16

The rotor assembly defined in claim 13, wherein wedge blocks are provided in said channels at opposite ends with their inner ends shaped to engage the adjacent knife blades, and adjustable abutment means is provided engaging one of said wedge blocks for exerting a longitudinal knife blade clamping pressure on the elements in each said channel.

Claim 17

A rotor assembly for a shavings making machine or the like comprising a rotor having an external periphery, means providing a plurality of circumferentially spaced longitudinally extending parallel outwardly open blade mounting channels on the rotor periphery, and a series of relatively short knife blade elements mounted in each of said channels in spaced relation longitudinally of the rotor and all being similarly inclined relative to an intersecting diametrical plane containing the rotor axis, a series of spacer elements being longitudinally slidably mounted in each channel, and said knife blade elements being clamped between adjacent spacer elements with their cutting edges projecting from the open channel.
