EP0004186A1 — A servicing attachment for a carding machine

Claim 1

Independent Claim 163 words

A servicing attachment for use on a carding machine, of the type which has a rotary device for co-operation with a roller of the machine, said servicing attachment having a longitudinally extending support structure and a traversing unit which unit itself comprises a carriage, a spindle for the rotary device mounted on said carriage, and a driving motor for the rotary device also mounted on said carriage, means mounting said traversing unit for longitudinal reciprocation on said support structure; an arm projecting laterally from each end of said support structure a stub axle carried by each said arm, said two stub axles being coaxial with the axis of said spindle, whereby when said stub axles are located in bearings on a carding machine, adjacent to a roller to be serviced, there is a range of angles about the axis of said spindle at which the attachment can be orientated without altering the setting between the rotary device and the roller to be serviced.

Claim 2

Dependent Claim 163 words

A servicing attachment for use on a carding machine, of the type which has a rotary device for co-operation with a roller of the machine, said servicing attachment having a longitudinally extending support structure and a traversing unit which unit itself comprises a carriage, a spindle for the rotary device mounted on said carriage, and a driving motor for the rotary device also mounted on said carriage, means mounting said traversing unit for longitudinal reciprocation on said support structure; an arm projecting laterally from each end of said support structure a stub axle carried by each said arm, said two stub axles being coaxial with the axis of said spindle, whereby when said stub axles are located in bearings on a carding machine, adjacent to a roller to be serviced, there is a range of angles about the axis of said spindle at which the attachment can be orientated without altering the setting between the rotary device and the roller to be serviced.

Claim 3

Dependent Claim 35 words

A servicing attachment as claimed in Claim 1, in which the arrangement is such that said traversing unit is entirely supported in respect of its own weight and any applied loads by said support structure.

Claim 4

Dependent Claim 138 words

A grinding attachment for use on a carding machine comprising a longitudinally extending beam, at least two laterally spaced longitudinally extending guide tracks carried by said beam, and a traversing unit which itself comprises a saddle having bearings engaging respectively on said guide tracks, said saddle also mounting a grinding wheel spindle disposed on one side of said beam and a driving motor for the grinding wheel spindle disposed on the opposite side of said beam to said grinding wheel spindle, there being an endless flexible drive member connecting said motor to said spindle, said flexible drive member having runs extending on opposite sides of said beam, said traversing unit being located by and adapted to slide longitudinally on said tracks, but being entirely supported in respect of its own weight and any applied loads by said beam.

Claim 5

Dependent Claim 138 words

A grinding attachment for use on a carding machine comprising a longitudinally extending beam, at least two laterally spaced longitudinally extending guide tracks carried by said beam, and a traversing unit which itself comprises a saddle having bearings engaging respectively on said guide tracks, said saddle also mounting a grinding wheel spindle disposed on one side of said beam and a driving motor for the grinding wheel spindle disposed on the opposite side of said beam to said grinding wheel spindle, there being an endless flexible drive member connecting said motor to said spindle, said flexible drive member having runs extending on opposite sides of said beam, said traversing unit being located by and adapted to slide longitudinally on said tracks, but being entirely supported in respect of its own weight and any applied loads by said beam.

Claim 6

Dependent Claim 89 words

A grinding attachment as claimed in Claim 3, in which said guide tracks are provided by a pair of rods of circular cross-section, the first of which said rods is located on said beam by a mounting of V cross-section, and the second of said rods being located on said beam by a mounting having a flat surface, whereby there is provision for some movement of said second rod towards and away from said first rod, there being means for clamping said two rods on to their respective mountings.

Claim 7

Dependent Claim 35 words

A grinding attachment as claimed in Claim 4, in which each of said bearings on said carriage is a recirculating ball-bearing, with the insides of the balls engaging directly on the outsides of said rods.

Claim 8

Dependent Claim 25 words

A grinding attachment as claimed in Claim 3, wherein said beam is of hollow rectangular cross-section, and said saddle is tubular and surrounds said beam.

Claim 9

Dependent Claim 42 words

A grinding attachment as claimed in Claim 4, in which said two guide tracks are positioned adjacent to opposite edges of one face of said beam, normal to the plane containing the axes of said driving motor and said grinding wheel attachment.

Claim 10

Dependent Claim 57 words

A grinding attachment as claimed in Claim 3, wherein said saddle of the traversing unit is of short length and embraces said beam, a first flange projecting from one side of said saddle supporting said grinding wheel mounting and a second flange projecting from the opposite side of said saddle providing a mounting for said driving motor.

Claim 11

Dependent Claim 120 words

A grinding attachment as claimed in Claim 3, wherein said traversing unit has a driving pulley at the motor side of said saddle and a driven pulley at the grinding wheel spindle side of said saddle, said flexible drive member connecting said two pulleys, said driven pulley being of smaller outside diameter than the dimension of said beam perpendicular to the plane passing through the axes of rotation of said motor shaft and said grinding wheel spindle, there being at least one guide pulley for said flexible drive member at the same side of said beam as said grinding wheel mounting, the geometrical arrangement of the pulleys being such that said flexible drive member is held clear of said beam.

Claim 12

Dependent Claim 87 words

A grinding attachment as claimed in Claim 3, in which an arm projects laterally from each end of said beam, and carries a stub axle, said two stub axles being coaxial with the axis of said grinding wheel mounting, whereby when said stub axles are located in bearings on a carding machine, there is a range of angles about the axis of said grinding wheel, at which said grinding attachment can be orientated, without altering the setting between said grinding wheel and the roller to be ground.
