Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
Web wiNding apparatus comprising a first support for an arbor at a normal winding station, a second support for an arbor at a temporary winding station, and means for rotating the arbor at the two winding stations, said rotating means being comprised of a pair of spaced-apart arms which are movable so that corresponding ends of the arms can be moved between the temporary winding station and the normal winding station, means carried by said ends of the arms for engaging an arbor and supporting it between the arms, means for rotating the engaging means so as to rotate the arbor supported thereby, and means for moving said arms so that an arbor at the temporary winding station which is engaged and rotated by the engaging means can be moved to the normal winding station as it rotates.
Claim 2
Dependent Claim
138 words
Web wiNding apparatus comprising a first support for an arbor at a normal winding station, a second support for an arbor at a temporary winding station, and means for rotating the arbor at the two winding stations, said rotating means being comprised of a pair of spaced-apart arms which are movable so that corresponding ends of the arms can be moved between the temporary winding station and the normal winding station, means carried by said ends of the arms for engaging an arbor and supporting it between the arms, means for rotating the engaging means so as to rotate the arbor supported thereby, and means for moving said arms so that an arbor at the temporary winding station which is engaged and rotated by the engaging means can be moved to the normal winding station as it rotates.
