extending toward the barrel below additionally in response to receiving an indication of the defective wire the scrap wire tray 138 slides into place beneath the accumulator as it moves the scrap wire tray aligns itself with the vertical axis 148 of the coiler above the barrel and below the accumulator so as to properly engage the vertically hanging wire 132 b the scrap wire tray moves on bearings 150 mounted on slide rods 152 and is shifted to this position by a pneumatic band cylinder located below it more detailed diagrams of a scrap tray and lifting mechanism are provided in the set of fig4 a 4j once the scrap wire tray 138 is in position above the barrel 122 the leading edge of the tray table snags the vertically hanging wire 132 b below the accumulator 134 the vertically hanging wire 132 a passes through a knife assembly 136 diagrams of a knife assembly are provided in the set of fig5 a 5h the knife assembly is used to cut the defective wire from the good wire by making two passes the first pass cuts the insulated wire below the defective wire area separating it from the good wire downstream below the second pass cuts above the defective wire area separating it from the good wire that follows from above specifically the reciprocating knife can cut.
