Abstract: Apparatus for segregating a jumbled mass of bobbins and delivery of the bobbins one at a time in axial orientation. A chain conveyor includes a plurality of buckets for receiving bobbins. These buckets open inwardly and together form the bottom of a hopper which receives the jumbled bobbins. As the conveyor is driven, a bucket receives a bobbin from the hopper and carries the bobbin upwardly along a substantially straight path to a discharge chute at an upper portion of the apparatus. The buckets have a particular cross-sectional configuration so that when they are on the straight upwardly extending path they will retain only one bobbin having a rounded cross section and within a particular range of diameters varying from an empty bobbin core to a full bobbin. If a second bobbin is picked up by a bucket it will drop from the bucket along the straight path and fall back into the hopper. By varying the inclination of the buckets along the straight portion of the path, the range may be varied. A bobbin in the hopper may tend to align itself with its axis parallel to the direction of movement of the buckets and would thus block the buckets from receiving bobbins having their axes transverse to the path of movement of the buckets. Such a parallel bobbin flips into position with its axis transverse to the path of the buckets upon movement of an inclined edge of an adjacent bucket against the bobbin in a direction transverse to the general upward path of the buckets. Concurrently with such transverse movement of each bucket, a finger is moved across the inclined edge and transfers any strands of yarn extending across the edge into a cutter. Alternatively, each bucket may be provided with a cutter which is moved across the inclined edge, in lieu of the finger and common cutter. Bobbins are fed into the hopper responsive to a reduction in weight of the bobbins in the hopper and the hopper is driven intermittently to deliver bobbins one at a time responsive to an external demand.

Abstract: A method and apparatus for severing a generally axially moving strand carried in an airstream. Closing of a slide valve member reduces the velocity of, and preferably substantially stops the stream, thereby reducing the velocity of and preferably stopping the strand. Substantially simultaneously therewith, and preferably after the strand is substantially stopped, a scissor is operated to sever the strand. As the valve member is closed, a guide thereon positions the strand for receipt by the scissor which is operated by a cam on the closed valve member to cut the strand.
