  • Patent number: 5002176
    Abstract: Suspension transport systems which operate automatically or predominantly automatically and which are used for the transport of spools make use of whole trains on which a plurality of spools is arranged. This, however, means that, e.g., in a ring spinning frame, the whole train will have to be exchanged when the first spool is empty. In order to avoid the resultant waste and in order to provide increased flexibility in the motion of the spools used in such a system of automatized or largely automatized operation, the present suspension transport system uses spools equipped with a travelling device of their own, the travelling device remaining on the spool when the spool is inserted into a processing machine. It is thus possible to handle each spool individually, as well as in a train. The suspension transport system is particlarly suitable for transverse insertion into a ring spinning frame.

  • Patent number: 4938149
    Abstract: The switch arrangement allocates first and second connections in groups to each other. A carriage is used which supports a number of connection elements corresponding to the number of second connections per each group. The carriage is movable along the first and the second connections in such fashion that each of the second connections of the group can be connected to the first connection allocated to that group. The switch arrangement is particularly suited for a suspension conveyor system for the feeding of flyer bobbins to ring spinners.
