1. the equipment for heat-treating multiple curved sewing needle, described equipment comprises:

  • For described multiple curved sewing needle to be transferred to the forwarder of receptor from curved sewing needle source;

    Contiguous described forwarder and the housing of locating, described housing has first end, the second end and extends to the opening of described second end from described first end, and described opening is aimed at described forwarder, passes described opening to enable described multiple curved sewing needle;

    Be positioned at described housing, for heating the thermal source of described multiple curved sewing needle when described multiple curved sewing needle being transferred to described second end of described housing from the described first end of described housing by described forwarder;

    AndFor providing the system of shroud gas, to minimize oxidation and the degraded of described multiple curved sewing needle when described multiple sewing needle passes described housing;

    Wherein, when described multiple curved sewing needle transmits between described curved sewing needle source to described receptor, described multiple curved sewing needle is heated to the temperature of the recrystallization temperature lower than curved sewing needle by described thermal source;

    AndWherein, described forwarder comprises the one or more bands be made up of paper or plastics at least in part.
