ABSTRACT:
An oven for continuously heating a cord, which oven has a housing defining an internal space for treatment of a cord. The housing has an inlet and an outlet communicating with the internal housing space and between which a cord being heated passes in a predetermined path. A heating chamber is defined within the internal housing space through which a cord being heated travels between the housing inlet and outlet. A first partition within the internal housing space is located beneath at least a part of the predetermined path and defines an upper wall of a hot air supply chamber within the internal housing space. The first partition has an elongate slit therethrough that resides beneath, and extends parallel to, the part of the predetermined path through which slit air in the hot air supply chamber is communicated to the heating chamber. An inlet opening in the housing communicates heated air to the hot air supply chamber. The housing has a second partition with first and second openings spaced in a lengthwise direction relative to the slit for causing heated air in the heating chamber to branch into each of the first and second openings. An air moving element is provided. There is further provided a conduit system for directing air from the first and second openings to the air moving element and for directing air accelerated by the air moving element to the hot air supply chamber. There is additionally a heater for air directed into the heating chamber.
