    Abstract: Improvements in apparatus of the type including a mandrel around which a continuous filament is coiled and which has a guide channel formed longitudinally therein for slidably receiving a continuous core to be positioned within the coil, and a mandrel holder holding the mandrel adjacent one end thereof and reciprocating with the latter in the longitudinal direction thereof in step with the formation of each convolution of the coil. A unit length of the core required for each coil convolution is forcibly pulled away from a core pay-off bobbin by a pair of pull-out rolls actuated intermittently by a ratchet mechanism. The mandrel holder has formed therein passageways through which the core travels from the pull-out roll pair to the entrance end of the guide channel in the mandrel. The passageways are adapted to provide several obtuse-angled bends for holding the core in frictional contact with the mandrel holder, so that the successive unit core lengths are delivered without tension to the guide channel in the mandrel with the reciprocation of the mandrel holder.

    Abstract translation: 包括围绕连续细丝卷绕的心轴并且纵向地形成有用于可滑动地容纳定位在线圈内的连续芯的引导通道的类型的设备的改进以及保持心轴邻近其一端的心轴夹持器和 与后者沿其纵向方向一起往复运动，同时形成线圈的每次卷绕。 通过由棘轮机构间歇地驱动的一对拉出辊将每个线圈卷绕所需的芯的单位长度强制地从芯放电线轴上拉开。 心轴保持器在其中形成有通道，芯通过该通道从拉出辊对行进到心轴中的引导通道的入口端。 通道适于提供几个钝角弯曲，用于保持芯与心轴保持器摩擦接触，使得连续的单元芯长度随着心轴保持器的往复运动而没有张力地传递到心轴中的引导通道。

    Abstract: A MACHINE FOR COILING CONTINUOUS LENGTH FILAMENTARY MATERIAL SO AS TO FORM A PAIR OF COILED FILAMENTS FOR USE IN SLIDE FASTENER STRINGERS COMPRISING A PAIR OF ROTATABLE SPOOLS HORIZONTALLY ARRANGED IN ALIGNMENT WITH ONE ANOTHER WITH EACH HAVING A SUPPLY OF FILAMENT WOUND THEREAROUND, A PAIR OF ARCUATED NEEDLE-LIKE STATIONARY MANDRELS AROUND WHICH THE FILAMENTS ARE WOUND AS THEY PASS FROM THE ROTATABLE SPOOLS, EACH OF SAID MANDRELS BEING RIGIDLY SUPPORTED AT A POINT OFFSET FROM THE AXES OF ROTATION OF THE ROTATABLE SPOOLS AND BEING RECTANGULAR SHAPE IN CROSS SECTION WHEREBY THE FILAMENTS ARE SUBJECTED TO A GREATER TENSION AS THEY PASS FROM THE ROTATABLE SPOOLS TO

    THE RESPECTIVE MANDRELS THROUGH ONE PART OF A REVOLUTION THAN THAT TO WHICH THE FILAMENTS ARE SUBJECTED DURING THE ROTATION OF THE SAME THROUGH THE OTHER PART OF THE REVOLUTION SO AS TO DEFORM THE FILAMENTS AT SPACED-APART INTERVALS THEREALONG IN COOPERATION WITH THE SIDES OF SAID MANDRELS IN EACH OF THE CONVOLUTIONS OF THE COILED FILAMENTS AT ONE SIDE THEREOF, AND A FORMING WHEEL HAVING A PAIR OF GROOVES ARRANGED AND AROUND THE PERIPHERY THEREOF IN WHICH THE FREE ENDS OF THE NEEDLE-LIKE MANDRELS ARE POSITIONED AND INTO WHICH GROOVES THE COILED FILAMENTS ARE DELIVERED.
