摘要： A tender patrols the spinning stations of a spinning frame and stops to service any station requiring attention. One reason for stopping the tender is because a strand normally spun into yarn has broken at a spinning station. In order to determine whether or not the strands are advancing normally at the spinning stations, the tender carries a transducer responsive to vibration of a feeler upon engaging the normally advancing strands to actuate an electronic switch which provides a signal permitting the tender to continue its patrolling operation. If a strand is not advancing normally the signal is not provided and the tender stops to service the station.

摘要： 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.

摘要： An automatic yarn twisting or spinning and rewinding system has at least one spinning frame with opposite banks of spinning stations. A pair of tenders, one for each of the banks, is provided for patrolling the stations and servicing any of the stations requiring attention. Upon stopping at a station requiring servicing, the tender doffs the bobbin (supply unit) at the station and donns an empty bobbin and starts the strand winding onto the empty bobbin. Thus there is a continuous supply of filled bobbins. The filled bobbins are conveyed to a readier of a winding machine at an end of the spinning frame or frames and, responsive to demand of the winding machine, the filled bobbins are deposited in the readier where they are suitably processed and then delivered to winding stations of the winding machine. The system is regulated so that the winding machine continuously uses the filled bobbins at substantially the same rate at which they are doffed from the spinning frame. After the yarn on the bobbins has been wound onto packages the bobbins may be ejected from the winding machine and are transferred back to a tender which thereupon donns the empty bobbins, as required, at the spinning stations.
