US 5,482,562 A · Method and an apparatus for the removal of fibrous material from a rotating shaft

Abstract

Apparatus and method for removing fibrous material wound around a generally cylindrical shaft rotated about a central longitudinal axis thereof. A cutter blade is provided to have a forward edge portion extending along the central longitudinal axis of the shaft, which edge portion is normally spaced from the shaft to define a non-cutting position. The edge portion of the cutter blade is moved about a reciprocating locus defined by a forward movement from the non-cutting position to a predetermined distance from the shaft effective to define a cutting position contacting the fibrous material, a lateral movement in the cutting position along the central longitudinal axis of the shaft to cut the fibrous material for its removal from the shaft, and a rearward movement from the shaft to return the edge portion to the non-cutting position.

Dependent claims

A method for removing fibrous material wound around a cylindrical shaft having a central longitudinal axis comprising the steps of:

providing a cutter blade having a forward edge portion extending parallel to the central longitudinal axis of said shaft, said edge portion being spaced from said shaft to define a non-cutting position;
rotating said shaft about the central longitudinal axis thereof;
forwardly moving, as said shaft is being rotated, said edge portion of said blade from said non-cutting position to a predetermined distance from said shaft effective to define a cutting position contacting the fibrous material;
laterally moving said edge portion of said blade in said cutting position parallel to the central longitudinal axis of said shaft to cut the fibrous material;
removing the cut fibrous material from said shaft;
and
rearwardly moving said edge portion of said blade from said shaft to return said edge portion to said non-cutting position.

4 more elements

An apparatus for removing fibrous material wound around a cylindrical shaft rotating about a central longitudinal axis thereof, said apparatus comprising:

a cutter blade having a forward edge portion extending parallel to the central longitudinal axis of the shaft, said edge portion being spaced from said shaft to define a non-cutting position;
and
a drive assembly coupled to said cutter blade to move said edge portion about a reciprocating locus defined by a forward movement from said non-cutting position to a predetermined distance from the shaft effective to define a cutting position contacting the fibrous material, a lateral movement in said cutting position parallel to the central longitudinal axis of the shaft to cut the fibrous material for its removal from the shaft, and a rearward movement from the shaft to return said edge portion to said non-cutting position.
