Abstract: An apparatus and a method for readying filled supply bobbins for receipt by a winding machine. As each bobbin is delivered to the apparatus it is given a preliminary servicing and inspection, whereupon the bobbin is either rejected or further processed by having a tailing or inner end of the body of yarn severed and an unwinding or outer end of the yarn picked-up and formed into a bunch which is deposited by means of a ram in a hollow core of the bobbin for retention therein until subsequent retrieval at the winding machine. Next the bobbin is again inspected and either rejected or directed to the winding machine. The rejected bobbins may be deposited in a bin for manual inspection.

Abstract: Apparatus for readying wound bobbins having a bore axially therethrough is described. The apparatus includes support means mounting the wound bobbin for delivery from a reserve position to an active unwinding position. Means are provided to create a zone of negative pressure through the bore of the bobbin when the wound bibbin is disposed in its reserve position. This zone of negative pressure acts to induce the outer yarn end of the wound bobbin into the bore when the yarn end is positioned proximate to the bore. A perforated member is provided adjacent the lower end of the bore. This member serves to control the extent to which the outer yarn end is drawn into the bore. This member also serves as a surface on which the yarn may be formed into a bunch if a bunch is desired and controls the amount of yarn drawn into the bore.

Abstract: A method and apparatus for readying filled supply bobbins for receipt by a winding machine. As each bobbin is processed its unwinding end is trimmed and a jet delivers the end through a mouth of a bunch maker and into a chamber which diverges from proximate the mouth. A vortex then carries the unwinding end into the chamber and deposits the unwinding end in a circuitous pattern substantially within an annular concavity in a perforate member forming an end face of the wide portion of the chamber. The amount of yarn deposited in the chamber may be varied to vary the size of a resultant bunch. In order to more readily and uniformly discharge the unwinding end from the perforate member and carry it outwardly through the chamber to provide a compact bunch, air for discharging the bunch is substantially simultaneously passed through all of the perforations with substantially equal force. The resultant bunch is compressed as the flow of air carries it through the chamber and into a neck between the chamber and the mouth. This air passes through vents in the chamber wall upstream of the neck to keep from driving the bunch through the mouth. A ram then moves the compressed bunch through the mouth and deposits the bunch at a desired location in a hollow core of the bobbin which has been positioned at the mouth. In order to provide the previously mentioned discharging air flow through the perforations, a second chamber is provided in communication through the perforate member with the first mentioned chamber. A piston is received in the second chamber. The vortex air stream which deposits the unwinding end on the perforate member passes through the perforations and in conjunction with vacuum applied to both ends of the second chamber, the piston is positioned at the end of the second chamber opposite the perforate member. The vortex air and the vacuum is then stopped and air pressure is introduced into the second cylinder to drive the piston toward the perforate member, whereupon the piston compresses the discharging air which passes with substantially equal force through the perforations of the perforate member.
