  • Patent number: 5078262
    Abstract: A conveyor which can be used both as a storage conveyor for storing goods hanging on hangers, particularly articles of clothing, and as a feed or an oblique conveyor. A traction belt which rotates in a direction of transport grasps the hanger hooks at their tip, whereby the hangers are engaged away from their center-of-gravity line. In this way, both the loading and the delivery points of the conveyor can be developed in an operatively reliable manner. Since the traction belt, structured preferably as a toothed belt, can be supported at any desired place without preventing or impeding its transporting ability, the storage conveyor can be of any desired length. By means of a guide ledge which is formed on the base body of the conveyor and extends parallel to the direction of transport, the hangers transported are prevented from swinging out and thus sliding out of the conveyor. The particular application of the conveyor is determined by selection of the traction belt.

  • Patent number: 5048436
    Abstract: A rotary looper for a lockstitch sewing machine, which can receive either a coreless thread package or a thread-wound bobbin. An upper bobbin-housing part is provided with two separate thread-tensioning elements and with respective thread-guide slots associated with them. In this way, the thread withdrawn either from a coreless thread package or a looper-thread bobbin passes over an optimally-shaped thread path on its way to the sewing area, and in both cases, a specifically adapted thread-tensioning force is exerted on the thread withdrawn. Preferably, the front part of the thread supply, in the coreless package or bobbin, can be accommodated in front of the movement path of the sewing needle, whereby the bobbin-housing can accommodate an extra-wide thread supply. An upwardly extended shoulder is provided on the lower part of the bobbin housing, so that the axially widened needle thread loop can slide unimpeded over the axially-extended bobbin-housing upper part.
