Abstract
Abstract A glass roving cutter with a rotatable cutter wheel having a plurality of axial cutting blades spaced at close intervals about its periphery and projecting outwardly therefrom, an anvil roll defining therewith a roving cutting nip and an endless arrangement of axial ejection bars capable of movement within the spacings between the cutting blades but inwardly recessed from the cutting edges thereof at the nip and thereafter moving out of the spacings to eject the cuttings from the blades; said ejection bars preferably being eccentrically mounted on cutter wheel shaft.

Claim 1
Independent Claim
133 words
A roving cutter comprising a shaft, a cutter wheel rotatably mounted on said shaft and having a plurality of axial cutting blades substantially equally spaced at close intervals about its periphery and projecting radially outwardly therefrom, an anvil member contiguous to one side of said cutter wheel defining therewith a roving cutting nip, an endless composite of ejection bars capable of movement in the spacings between said blades, a frame supporting said bars and mounted on said shaft for rotation about a pivot axis eccentric in a direction away from said anvil member to the axis of rotation of said cutter wheel, said frame including a hub rotatably journaled on said shaft, support means extending radially from said hub, and ring means on said support means for holding opposite ends of said bars.
